Abstract
Mammary serine protease inhibitor or Maspin has been characterized as a class II tumor suppressor gene in several cancer types, among them prostate cancer (CaP). Androgen ablation is an effective therapy for CaP, but with short-term effectiveness, thus new therapeutic strategies are actively sought. The present study is aimed to explore the effects of a glucosamine derivative, 2-(N-Carbobenzyloxy)l-phenylalanylamido-2-deoxy-β-d-glucose (NCPA), on two CaP cell lines, PC3 and LNCaP. In particular we analyzed the impact of NCPA on Maspin production, cell viability and cell cycle progression and apoptosis/necrosis pathway activation in PC3 and LNCaP cell lines. NCPA is able to stimulate Maspin production in PC3 and not in LNCaP cell lines. NCPA blocks the PC3 cell cycle in G1 phase, by inhibiting Cyclin D1 production and induces the apoptosis, therefore interfering with aggressiveness of this androgen-insensitive cell line. Moreover, NCPA is able to induce the expression of Maspin in LNCaP cell line treated with androgen receptor inhibitor, Bicalutamide, and in turn to stimulate the apoptosis of these cells. These findings suggest that NCPA, stimulating the endogenous production of a tumor suppressor protein, could be useful in the design of new therapeutic strategies for treatment of CaP.
