Publication date: Available online 22 July 2017 Source:Methods Author(s): Cornelia Veelken, Gert-Jan Bakker, David Drell, Peter Friedl Organotypic in vitro culture of 3D spheroids in extracellular matrix represent a promising cancer therapy prediction model for personalized medicine screens, due to their controlled experimental conditions and physiological similarities to in vivo models. As in tumors in vivo, 3D invasion cultures identify intratumor heterogeneity of growth, invasion and apoptosis induction by cytotoxic therapy. We here combine in vitro 3D spheroid invasion culture with irradiation and automated nucleus-based segmentation for single cell analysis to quantify growth, survival, apoptosis and invasion response during experimental radiation therapy. As output, multi-parameter ...

Malignancy Rates of Thyroid Cytology: Cyst Fluid Benign or Non-Diagnostic?
CONCLUSIONS Despite the limited number of cases, our study concluded that cystic content was closer to the benign category than the non-diagnostic category if the assessment was based on malignancy rates. In this group, similar to aspirations containing plenty of lymphocytes that indicates colloid or lymphocytic thyroiditis, it is still controversial whether criterion for adequacy of follicular epithelial cells should be sought, or if they should be regarded as benign in order to prevent unnecessarily performance of repeat aspirations.

Clinical Approach to Incidental Pancreatic Cystic Neoplasm in Outpatient Clinics.
Authors: Woo YS, Lee KT Abstract Cystic lesions of the pancreas are increasingly observed due to increased use of abdominal images. The malignant rate of pancreas cystic lesion varies widely between various types. Identification of malignant or high-risk lesions is important when determining the appropriate course of management. Using these image findings, including cyst size, presence of solid components, and pancreatic duct involvement, the 2012 International Association of Pancreatology (IAP) and the 2015 American Gastroenterological Association (AGA) guidelines provide a rationale in identifying higher risk patients requiring further workups using an endoscopic ultrasound (EUS). EUS with fine needle aspiration and cytology allows confirmation of the cyst type and determines the...

Beware! Live Virus in Oncologic Therapy: Talimogene Laherparepvec (TVEC) and Nursing Considerations
Melanoma is the most common form of skin cancer. According to the American Cancer Society (2016), melanoma accounts for 76,380 estimated diagnosed new cases and 10,130 deaths in the United States each year. With the increasing numbers of melanoma cases, a new oncolytic drug, Talimogene laherparepvec (TVEC), was recently approved by the Food and Drug Administration (FDA) for use in the local treatment of melanoma tumors, recurrent after initial surgery. TVEC contains an attenuated live herpes simplex 1 virus which is genetically modified to replicate inside tumors, causing rapid oncolysis. (Source: Journal of PeriAnesthesia Nursing)

Post-Operative Urinary Retention (POUR) is a common phenomenon and is associated with many risk factors. Identifying high risk patient populations and assessing them for voiding will enhance patient safety. A need was identified to have a standardized voiding criteria guideline in place to improve the standardization among Post Anesthesia Care Unit (PACU) nursing providers. A knowledge gap was acknowledged in determining voiding criteria for surgical oncology patients. Based on this identified knowledge gap, a nursing initiative was developed to evaluate the literature and determine best practice guidelines for nursing staff.

ObjectivesPrimary squamous cell carcinoma (SCC) of the thyroid is a rare disease. It usually presents with locally advanced disease and has an overall poor prognosis. In this study, we investigated the characteristics and outcomes of patients with SCC of the thyroid, and reported our experience with chemotherapy with lenvatinib in the treatment of SCC of the thyroid.MethodsThe management outcome of 10 patients who had SCC of the thyroid between January 2000 and 2015 at Kyushu University Hospital or associated facilities was reviewed.ResultsThere were 3 males and 7 females, ranging in age from 53 to 77 years. Extent of disease was staged as follows: stage IVA, 3 cases; stage IVB, 3 cases; stage IVC, 4 cases. Only tracheostomy was applied for 2 cases, surgical resection, such as total thyroidectomy and neck dissection, for the other 8 cases. Radiotherapy following surgical treatment was applied for 9 cases. Four patients started on oral lenvatinib due to recurrent or progressive SCC of the thyroid. The one year actuarial survival rate of patients was 22.7%. There was no 2-year survivor of all patients.ConclusionsTreatment should primarily be targeted at surgical resection with negative margins in patients with resectable disease. Lenvatinib may show promise to potentially extend survival.

Modulatory effect of neoadjuvant chemotherapy on the prognosis of patients with breast cancer.
CONCLUSION: Changes in hormone receptor status, HER2 status and Ki-67 occurred after NAC in patients with LABC. A change from negative to positive hormone receptor status and HER2 status offers new treatment options, like endocrine therapy, and/or trastuzumab therapy for breast cancer patients. The decrease of Ki-67 expression after NAC was associated with better outcome. PMID: 28730768 [PubMed - in process] (Source: Journal of B.U.ON.)

A mathematical optimization model for efficient assignment of inpatients in an oncology center in China.
Authors: Lv M, Kou B, Zhou ZL, He WB Abstract This paper addresses a problem for assignment of chemo-receiving inpatients in an oncology care center, which has not been addressed in the literature. Chemotherapy is regarded as one of the most effective treatments for cancer. In recent years, as cancer incidence increased, the number of patients admitted to a cancer treatment center has also been rising. How to balance the workload of medical service resources by planning admission of patients has become an essential problem that must be given consideration by policy- makers. The allocation of chemotherapy patients, different from that of the routine inpatients, is restrained by treatment agreements of patients and presents periodic features. Therefore, the allocation of chemotherapy...

DNA mismatch repair deficiency in lung and oral cavity carcinomas: the role of histogenetic origin.
Authors: Spetsotaki KN, Tsiambas E, Stamatelopoulos A, Fotiades PP, Kastanioudakis I, Tomos P, Ragos V Abstract DNA mismatch repair system (DNA MMR) is a crucial genetic mechanism for DNA homeostasis in prokaryotic and eukaryotic cells. During DNA replication and also recombination, point intra-nucleotide errors including base deletion, insertion, and mis-incorporation happen. These raised abnormalities in the newly synthesized DNA strand could affect negatively the stability of the molecule and the function of the corresponding genes. DNA MMR proteins prevent these errors by recognizing and repairing them, securing directly the normal anatomy of the DNA double strand and indirectly the expression of the genes. Specific genomic alterations - mutations, loss of heterozygosity (LOH),...

Myeloid suppressor cells in cancer and autoimmunity.
Authors: Sica A, Massarotti M Abstract A bottleneck for immunotherapy of cancer is the immunosuppressive microenvironment in which the tumor cells proliferate. Cancers harness the immune regulatory mechanism that prevents autoimmunity from evading immunosurveillance and promoting immune destruction. Regulatory T cells, myeloid suppressor cells, inhibitory cytokines and immune checkpoint receptors are the major components of the immune system acting in concert with cancer cells and causing the subversion of anti-tumor immunity. This redundant immunosuppressive network poses an impediment to efficacious immunotherapy by facilitating tumor progression. Tumor-associated myeloid cells comprise heterogeneous populations acting systemically (myeloid-derived suppressor cells/MDSCs) and/or ...

Infectious and Noninfectious Pulmonary Complications in Patients With Primary Immunodeficiency Disorders.
Authors: Yazdani R, Abolhassani H, Asgardoon M, Shaghaghi M, Modaresi M, Azizi G, Aghamohammadi A Abstract Primary immunodeficiency disorders (PIDs) are caused by 1 or more defects of the immune system. Patients are more likely to experience recurrent and/or severe infections and tend to develop a wide range of complications. Respiratory diseases are the main and initial manifestation in most cases and the most common complication. Pulmonary complications cause significant morbidity and mortality in patients with PIDs. Early diagnosis and appropriate treatment can prevent or at least slow the development of respiratory complications. Since the spectrum of pulmonary complications in PIDs is broad, we divided pulmonary complications into upper respiratory complications (eg, sinusitis...

Authors: Tully CM, Chinnakannan S, Mullarkey CE, Ulaszewska M, Ferrara F, Temperton N, Gilbert SC, Lambe T Abstract Seasonal influenza viruses are a common cause of acute respiratory illness worldwide and generate a significant socioeconomic burden. Influenza viruses mutate rapidly, necessitating annual vaccine reformulation because traditional vaccines do not typically induce broad-spectrum immunity. In addition to seasonal infections, emerging pandemic influenza viruses present a continued threat to global public health. Pandemic influenza viruses have consistently higher attack rates and are typically associated with greater mortality compared with seasonal strains. Ongoing strategies to improve vaccine efficacy typically focus on providing broad-spectrum immunity; although B an...

Authors: Venet F, Demaret J, Blaise BJ, Rouget C, Girardot T, Idealisoa E, Rimmelé T, Mallet F, Lepape A, Textoris J, Monneret G Abstract T lymphocyte alterations are central to sepsis pathophysiology, whereas related mechanisms remain poorly understood. We hypothesized that metabolic alterations could play a role in sepsis-induced T lymphocyte dysfunction. Samples from septic shock patients were obtained at day 3 and compared with those from healthy donors. T cell metabolic status was evaluated in the basal condition and after T cell stimulation. We observed that basal metabolic content measured in lymphocytes by nuclear magnetic resonance spectroscopy was altered in septic patients. Basal ATP concentration, oxidative phosphorylation (OXPHOS), and glycolysis pathways in T cells w...

Galectin-1-Driven Tolerogenic Programs Aggravate Yersinia enterocolitica Infection by Repressing Antibacterial Immunity.
Authors: Davicino RC, Méndez-Huergo SP, Eliçabe RJ, Stupirski JC, Autenrieth I, Di Genaro MS, Rabinovich GA Abstract Yersinia enterocolitica is an enteropathogenic bacterium that causes gastrointestinal disorders, as well as extraintestinal manifestations. To subvert the host's immune response, Y. enterocolitica uses a type III secretion system consisting of an injectisome and effector proteins, called Yersinia outer proteins (Yops), that modulate activation, signaling, and survival of immune cells. In this article, we show that galectin-1 (Gal-1), an immunoregulatory lectin widely expressed in mucosal tissues, contributes to Y. enterocolitica pathogenicity by undermining protective antibacterial responses. We found higher expression of Gal-1 in the spleen and Peyer's patches of ...

SYPL1 overexpression predicts poor prognosis of hepatocellular carcinoma and associates with epithelial-mesenchymal transition.
Authors: Chen DH, Wu QW, Li XD, Wang SJ, Zhang ZM Abstract Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide, which is mainly due to relapse and metastasis. Synaptophysin-like 1 (SYPL1), a member of SYP family proteins, exerts complicated functions, which prompted us to wonder whether SYPL1 contributed to HCC progress. Herein, we performed integrative experiments of quantitative real-time polymerase chain reaction (qRT-PCR), western blot analysis and immunohistochemistry (IHC), and found that SYPL1 overexpression in HCC tissues was closely correlated with several malignant clinicopathologic features of HCC. The results from IHC in serial sections of HCC tissues further indicated that SYPL1 expression was associated with epithelial-mesenchymal ...

Snail maintains metastatic potential, cancer stem-like properties, and chemoresistance in mesenchymal mouse breast cancer TUBO ‑P2J cells.
In this study, we analysed the role of Snail in the highly metastatic mesenchymal TUBO‑P2J mouse breast cancer cells, by loss of function using short hairpin RNA. Though silencing Snail did not restore the E-cadherin expression or induce morphological changes, Snail silencing significantly ablated in vitro and in vivo metastatic potentials. In addition, Snail silencing also reduced resistance to chemotherapy drugs and cancer stem-like properties, such as CD44 expression, aldehyde dehydrogenase (ALDH) activity, colony formation, and in vivo tumour formation and growth. However, radioresistance was not decreased by silencing Snail. Collectively, this study suggested that Snail is a main regulator of the maintenance of malignancy potentials and is a good target to prevent cancer metasta...

miR-216b inhibits glioma cell migration and invasion through suppression of FoxM1.
Authors: Zhang T, Ma G, Zhang Y, Huo H, Zhao Y Abstract MicroRNAs (miRNAs) play a vital role in tumour biological and pathologic processes. In the present study, we aimed to detect the expression and biological role of miR-216b in glioma. Our data showed that miR-216b was significantly downregulated in human glioma tissues and cells. Ectopic expression of miR-216b inhibited the proliferation and invasion of U87 and U251 cells and suppressed the growth of xenograft tumours in vivo. Bioinformatic and luciferase reporter analyses identified Forkhead box protein M1 (FoxM1) as a direct target of miR-216b. Overexpression of miR-216b inhibited the expression of FoxM1 in glioma cells. Rescue experiments demonstrated that co-transfection of FoxM1 lacking the 3'-untranslated region partial...

Phosphorylation of Bcl-2 plays an important role in glycochenodeoxycholate-induced survival and chemoresistance in HCC.
Authors: Zhou M, Zhang Q, Zhao J, Liao M, Wen S, Yang M Abstract Hepatocellular carcinoma (HCC) is a highly malignant tumor and can evolve rapidly to resistance to chemotherapies. Glycochenodeoxycholate (GCDA), which is toxic and hydrophobic, is the main ingredient in the bile and associated with carcinogenesis of gastrointenstinal tumors. Bcl-2 is the most important anti-apoptotic protein and overexpressed in various human tumors. In the present study, we found that GCDA can induce the chemoresistance of human liver cancer cells and specific depletion of Bcl-2 by RNA interference blocks GCDA-stimulated chemoresistance, which indicate the pivotal role of Bcl-2 in such process. Mechanistically, GCDA simultaneously stimulates phosphorylation of Bcl-2 at Ser70 site and activates extra...

In vivo and in vitro inhibition of human gastric cancer progress by upregulating Kank1 gene. Oncol Rep. 2017 Jul 17;: Authors: Chen T, Wang K, Tong X Abstract Recent research has found that Kank1 gene, as one of the important members of the Kank gene family, plays an important role in the occurrence and development of malignant tumors. As a brand new cancer suppressor gene, its expression is significantly downregulated or missing in various kinds of malignant tumors. However, no report on the specific role of Kank1 in the genesis and development of gastric cancer is available yet. In the present study, we found significantly lower expression of Kank1 gene in human gastric cancer cells. When Kank1 gene was upregulated, it was found that the proliferation of gastric ca...

Bufalin reverses acquired drug resistance by inhibiting stemness in colorectal cancer cells.
Authors: Sun J, Xu K, Qiu Y, Gao H, Xu J, Tang Q, Yin P Abstract Drug resistance is an obstacle to chemotherapy in tumor patients. Recent studies have shown that the high stemness of cancer cells may be induced by chemotherapeutic drugs, which is correlated with drug resistance. In the present study, we investigated the effects of bufalin on the stemness of colorectal cancer. We found that cisplatin could induce high stemness through the tumorsphere formation assay in vitro and in vivo in the colorectal cancer cell lines HCT116 and LoVo. In addition, cisplatin-treated tumorsphere cells showed drug‑resistant properties. These results suggested that acquired drug resistance induced by cisplatin in colorectal cancer cells occurred via high stemness. On assessing the effects of buf...

Anacardic acid induces cell apoptosis of prostatic cancer through autophagy by ER stress/DAPK3/Akt signaling pathway.
In this study we found that anacardic acid inhibited cell proliferation, induced apoptosis and caspase-3/9 activities and Bax protein expression of prostatic cancer. Anacardic acid induced the ER stress inducing factors (BiP, CHOP, p-eIF2α), autophagy, LC3, Beclin-1, Atg 7 and DAPK3 protein expression, and suppressed p-Akt and p-mTOR protein expression of prostatic cancer. Si-CHOP was used to inhibit ER stress in prostatic cancer by anacardic acid, which showed that the cell proliferation was increased, apoptosis, and caspase-3/9 activities and Bax protein expression was suppressed, autophagy, LC3, Beclin-1, Atg 7 and DAPK3 protein expression was reduced, and p-Akt and p-mTOR protein expression was promoted. DAPK3 inhibited p-Akt and p-mTOR protein expression, enhanced the anticancer effe...

Let-7c-5p inhibits cell proliferation and induces cell apoptosis by targeting ERCC6 in breast cancer.
In this study, we found that let-7c-5p expression was clearly downregulated in breast cancer tissues compared with that of corresponding adjacent tissues. Furthermore, overexpression of let-7c-5p in MCF-7 breast cancer cells could significantly inhibit cell proliferation and induce cell apoptosis. The target genes of let-7c-5p were predicted by the way of bioinformatics, and validated by dual luciferase reporter assay and western blotting demonstrating that excision repair cross complementing 6 (ERCC6) gene was a direct target. Collectively, the present study suggested that let-7c-5p acted as a tumor suppressor in breast cancer possibly by negatively regulating ERCC6, which took an important part in nucleotide excision repair and it may provide a new potential strategy for breast cancer t...

LHX3 is an early stage and radiosensitivity prognostic biomarker in lung adenocarcinoma.
Authors: Lin X, Li Y, Wang J, Han F, Lu S, Wang Y, Luo W, Zhang M Abstract Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. We previously identified LHX3 as a new preferentially expressed gene in NSCLC. In the present study, we sought to determine its expression, the clinical relevance and the functional roles in NSCLC. LHX3 expression is sharply increased in carcinoma tissues compared to non-carcinoma tissues. Relational analysis reveals a significant association between LHX3 expression and clinical stage (n=172, p=0.032) or radiotherapy (n=167, p=0.022) of patients. LHX3 expression is much higher in the patients at advanced stages (stage III-IV) than in the patients at early stages (stage I-II, p=0.0304), and LHX3 expression is remarkably increased in ...

However, new findings have shown that it is expressed in greater amounts in advanced cancers than in early-stage tumors. The role and clinical significance of ANP32A in colorectal cancer (CRC) is still unknown. In the present study, the expression of ANP32A was assessed in 68 CRC patients by IHC, and then the correlation of its expression with clinicopathological factors was investigated using the Allred, Klein and immune response scoring system analysis. Western blot and real-time PCR analyses were used to assess ANP32A expression and the activity of Akt and p38 ...

Heat shock-induced HIKESHI protects cell viability via nuclear translocation of heat shock protein 70.
In this study, we examined the intracellular movement of HSP70 during heat shock to investigate the significance of HIKESHI expression in gastric cancer (GC) and determine if HIKESHI inhibition has cytotoxic effects. We examined HIKESHI using GC cell lines and immunostaining in 207 GC tissue samples. HIKESHI expression in GC tissues was associated with the progression of lymphatic invasion. Suppressing HIKESHI using siRNA did not affect cell viability at normal temperatures. However, suppressing HIKESHI during heat shock inhibited HSP70 nuclear transport and suppressed cell viability. Our results suggest that HIKESHI is a marker of cancer progression and that the combination of HIKESHI inhibition and hyperthermia is a therapeutic tool for refractory GC.

SMURF1 promotes the proliferation, migration and invasion of gastric cancer cells.
Authors: Tao Y, Sun C, Zhang T, Song Y Abstract Smad ubiquitin regulatory factor 1 (SMURF1), a well-known E3 ubiquitin ligase, targets substrate proteins for ubiquitination and proteasomal degradation. Accumulating studies have shown that SMURF1 acts as an oncogenic factor in human malignancies. However, the clinical significance of SMURF1 and its role in gastric cancer (GC) remain unclear. The expression of SMURF1 was detected in 68 cases of GC and corresponding tumor-adjacent specimens. Our results revealed that SMURF1 was prominently overexpressed in GC specimens compared to corresponding tumor-adjacent tissues. Furthermore, increased levels of SMURF1 mRNA were also observed in GC cell lines. Clinicopathological detection ascertained that SMURF1-positive expression was associa...

Achaete-scute Complex Homologue 2 Accelerates the Development of Sj ögren's Syndrome-like Disease in the NOD/ShiLtJ Mouse.
This study examined whether Ascl2 plays a role in the development of SS. NOD/ShiLtJ mice were injected with an Ascl2-overexpression vector, and the infiltration of lymphocytes into salivary and lacrimal glands was assessed. The expression of inflammatory cytokines and chemoattractants for T or B cells was measured. The activation of TFH cells was assessed using a specific marker of TFH cells. Ascl2 level was also measured in SS patients. Overexpression of Ascl2 increased the expression of C-X-C chemokine receptor type 5 (CXCR5) in both salivary and lacrimal glands (p<0.0001). Overexpression of Ascl2 also increased the expression of proinflammatory cytokines and chemoattractants including interleukin 6 (IL-6), tumor necrosis factor-α, IL-8, programmed cell death 1 (PD-1), IL-21, and B-c...

Uncovering the role of brain ‐derived neurotrophic factor/tyrosine kinase receptor B signaling in head and neck malignancies
Brain‐derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors that was first known as responsible for sustain the growth, function, and plasticity of neural cells. BDNF exerts its effects by binding to the tyrosine kinase receptor B (TrkB). The BDNF/TrkB axis has been reported to be overexpressed in several neurogenic and non‐neurogenic tumors. Its higher expression was associated with a poor prognosis to patients affected by different human malignancies, tumor growth, invasion, and metastasis; epithelial‐mesenchymal transition and resistance to chemotherapy. BDNF/TrkB represent promising targets to the development of novel anticancer therapies. Some clinical trials are currently evaluating the efficacy of Trk protein‐target drugs in different ty...

Oxidative stress and inhibition of nitric oxide generation underlie methotrexate-induced senescence in human colon cancer cells
Publication date: Available online 21 July 2017 Source:Mechanisms of Ageing and Development Author(s): Magdalena Dabrowska, Lukasz Uram, Zbigniew Zielinski, Wojciech Rode, Ewa Sikora The response of human colon cancer C85 cells to methotrexate takes the form of reversible growth arrest of the type of stress-induced senescence. In the present study it is shown that during C85 cell progression into methotrexate-induced senescence, dihydrofolate reductase, the primary intracellular target for the drug, is stabilized at the protein level and its enzymatic activity, assayed in crude cellular extracts, decreases by 2-fold. Dihydrofolate reductase inhibition results in an increase in dihydrobiopterin level and an ultimate decrease in the tetrahydrobiopterin: dihydrobiopterin ratio in senescent c...

MicroRNAs as Multifaceted Players in Glioblastoma Multiforme.
Authors: Mercatelli N, Galardi S, Ciafrè SA Abstract Glioblastoma multiforme (GBM) is the most common and inevitably lethal primary brain tumor, with a median survival rate of only 15 months from diagnosis. The current standard treatment involves maximal surgical resection flanked by radiotherapy and chemotherapy with the alkylating agent temozolomide. However, even such aggressive treatment is never curative, and recurrent tumors always arise, commonly in more aggressive, chemo- and radio-resistant forms, leading to untreatable and deadly tumors. MicroRNAs, recognized major players in cancer, are deeply involved in GBM, as shown by more than a decade of studies. In this review, we revise the main milestones of MicroRNA studies in GBM, and the latest relevant discoveries in this f...

Following MicroRNAs Through the Cancer Metastatic Cascade.
Authors: Grisard E, Nicoloso MS Abstract Approximately a decade ago the first MicroRNAs (MiRNAs) participating in cancer metastasis were identified and metastmiRs were initially only a handful. Since those first reports, MiRNA research has explosively thrived, mainly due to their revolutionary mechanism of action and the hope of having at hand a novel tool to control cancer aggressiveness. This has ultimately led to delineate an almost impenetrable regulatory network: hundreds of MiRNAs transversally dominating every aspect of normal and cancer biology, each MiRNA having hundreds of targets and context-dependent activity. Providing a comprehensive description of MiRNA roles in cancer metastasis is a daunting task; nevertheless, we still believe that grasping the big picture of MiRN...

MicroRNAs as Key Effectors in the p53 Network.
Authors: Goeman F, Strano S, Blandino G Abstract The guardian of the genome p53 is embedded in a fine-spun network of MicroRNAs. p53 is able to activate or repress directly the transcription of MicroRNAs that are participating in the tumor-suppressive mission of p53. On the other hand, the expression of p53 is under tight control of MicroRNAs that are either targeting directly p53 or factors that are modifying its protein level or activity. Although the most important function of p53 is suggested to be transcriptional regulation, there are several nontranscriptional functions described. One of those regards the modulation of MicroRNA biogenesis. Wild-type p53 is increasing the maturation of selected MicroRNAs from the primary transcript to the precursor MiRNA by interacting with th...

MicroRNAs in Oncogenesis and Tumor Suppression.
Authors: Barbato S, Solaini G, Fabbri M Abstract MicroRNAs (MiRNAs) have emerged in the last 15 years as central players in the biology of cancer. Increasing lines of evidence have supported their regulatory role in the expression of both oncogenes and tumor-suppressor genes, progressively clarifying which genes are modulated by specific MiRNAs dysregulated in cancer. Intriguingly, a "target-specific" understanding of MiRNA function in oncology has been replaced by a more "pathway-specific" vision of their involvement in cancer biology. This work provides a state-of-the-art knowledge of the role of MiRNAs in the most frequently altered signaling pathways in cancer cells and provides an updated overview on some of the most relevant findings trying to decode the complex molecular mec...

Understanding the Genomic Ultraconservations: T-UCRs and Cancer.
Authors: Fabris L, Calin GA Abstract Transcribed ultraconserved regions (T-UCRs) are genomic regions conserved across large evolutionary distances, which encode for noncoding RNAs that serve as regulators of gene expression. Although T-UCRs have been linked to multiple aspects of mammalian gene regulation, the roles of their extreme evolutionary conservation remain largely unexplained. Growing body of literature is now focusing on T-UCRs as potential cancer biomarkers or as new drug targets. Here we present an overview of the discoveries so far published about the role of T-UCR in cancer and disease.

Impact of MicroRNAs in the Cellular Response to Hypoxia.
Authors: Bertero T, Rezzonico R, Pottier N, Mari B Abstract In mammalian cells, hypoxia, or inadequate oxygen availability, regulates the expression of a specific set of MicroRNAs (MiRNAs), termed "hypoxamiRs." Over the past 10 years, the appreciation of the importance of hypoxamiRs in regulating the cellular adaptation to hypoxia has grown dramatically. At the cellular level, each hypoxamiR, including the master hypoxamiR MiR-210, can simultaneously regulate expression of multiple target genes in order to fine-tune the adaptive response of cells to hypoxia. This review addresses the complex molecular regulation of MiRNAs in both physiological and pathological conditions of low oxygen adaptation and the multiple functions of hypoxamiRs in various hypoxia-associated biological proce...

MicroRNAs in DNA Damage Response, Carcinogenesis, and Chemoresistance.
Authors: Fang Y, Zhang L, Li Z, Li Y, Huang C, Lu X Abstract In the classical model of tumorigenesis, cancer develops via slowly accumulating mutations that facilitate uncontrolled cell growth and allow cells to escape apoptosis. Oncogenes and tumor suppressor genes regulate the key signaling pathways involved in tumorigenesis and cancer progression. Moreover, studies indicate that MicroRNAs (MiRNAs) are also key parts of these processes. MiRNAs are short, noncoding RNAs that regulate the expression of target genes at the posttranscriptional level. By regulating the expression of numerous cytokines, MiRNAs play crucial roles in cell growth, apoptosis, and stemness maintenance. Abundant evidence demonstrates that MiRNAs can function as both oncogenes and tumor suppressors in accommo...

Cancers, Vol. 9, Pages 94: Targeting Platelets for the Treatment of Cancer
Authors: Omar Elaskalani Michael Berndt Marco Falasca Pat Metharom The majority of cancer-associated mortality results from the ability of tumour cells to metastasise leading to multifunctional organ failure and death. Disseminated tumour cells in the blood circulation are faced with major challenges such as rheological shear stresses and cell-mediated cytotoxicity mediated by natural killer cells. Nevertheless, circulating tumour cells with metastatic ability appear equipped to exploit host cells to aid their survival. Despite the long interest in targeting tumour-associated host cells such as platelets for cancer treatment, the clinical benefit of this strategy is still under question.
