DMKN contributes to the epithelial-mesenchymal transition through increased activation of STAT3 in pancreatic cancer

Summary

DMKN was first identified in relation to skin lesion healing and skin carcinoma. Recently, its expression has been associated with pancreatic cancer tumorigenesis, although its involvement remains poorly understood. Herein, we show that DMKN loss of function in Patu-8988 and PANC-1 pancreatic cancer cell lines results in reduced phosphorylation of signal transducer and activator of transcription-3 (STAT3), and increased activation of extracellular signal-regulated kinase (ERK1/2) and AKT serine/threonine kinase. This decreases the proliferation ability of pancreatic ductal adenocarcinoma (PDAC) cells. In addition, DMKN knockdown decreased the invasion and migration of PDAC cells, partially reversed the epithelial-mesenchymal transition, retarded tumor growth in a xenograft animal model by decreasing the density of microvessels, and attenuated the distance metastasis of human PDAC in a mouse model. Taken together, these data suggest that DMKN may be a potential prognostic biomarker and therapeutic target in pancreatic cancer.
