Chalcones exhibit chemopreventive and antitumor effects. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a naturally occurring anticancer agent that induces apoptosis in cancer cells and is not toxic to normal cells. We examined the cytotoxic and apoptotic effect of five chalcones in combination with TRAIL on prostate cancer cells. The cytotoxicity was evaluated by the MTT an...

background: during the past few years, hesa-a, a herbal-marine mixture, has been used to treat cancer as an alternative medicine in iran. however, weight of the evidence is not sufficient to accept or refuse the use of this compound as a cytotoxic drug. we investigated the selective anticancer effects of hesa-a on breast, prostate, colon, and glioblastoma multiforme (gbm) neoplastic cell lines....

prostate cancer is a devastating disease for which current therapies are inadequate. various lines of evidences have suggested the 5-lipoxygenase (5-lox) pathway and the leukotriene receptor pathway are potential targets for prevention or treatment of prostate cancer. thus, search for new anti-cancer drugs targeting 5-lox and leukotriene is very essential and important. the objective of the pre...

INTRODUCTION Bispecific antibodies (BiAbs) are used to enhance targeting of T cells and other cytotoxic agents to tumors while minimizing non-specific tissue toxicities. This study compares the targeting efficacy of 3 BiAbs derived from chemically heteroconjugating a T cell-directed monoclonal antibody (mAb) to 9184, 9187 or 9189, which are mAbs directed at extracellular antigens expressed on h...

Prostate-specific membrane antigen (PSMA) is an attractive target for treatment of prostate cancer. Using the PSMA-recognizing mouse monoclonal antibody 2C9 obtained in our previous study, the biological activities of PSMA antibody were evaluated. Mouse-human chimeric IgG1 of 2C9 (KM2777) showed antibody-dependent cellular cytotoxicity activity against PSMA-expressing prostate cancer cells in t...

Core2 β-1,6-N-acetylglucosaminyltransferase (C2GnT) forms an N-acetylglucosamine branch in the O-glycans (core2 O-glycans) of cell surface glycoproteins. We previously revealed that the expression of C2GnT is positively correlated with poor prognosis in prostate cancer patients. However, the detailed mechanisms underlying their poor prognosis remain unclear. In the current study, we report that...

introduction: prostate cancer is one of the most common cancers among males and the second factor resulting to death due to cancer among them.(1) the median age of its diagnosis is 65 years. the initial treatment includes androgen ablation or orchiectomy.(2, 3) in case of patient’s hormone refractory, chemotherapy would be substituted. the objective of this study is the consideration of intermi...

Four triterpenes were isolated from a traditional Japanese tea product produced by anaerobic microbial fermentation of heated green tea leaves (Camellia sinensis). Two of the compounds were novel and characterized by spectroscopic investigation to be 13,26-epoxy-3β,11α-dihydroxyolean-12-one and 3β,11α,13β-trihydroxyolean-12-one. Two known triterpenes were identified as taraxastane-3β,20β-diol a...

Among the many identified androgen-regulated genes, sGCα1 (soluble guanylyl cyclase α1) appears to play a pivotal role in mediating the pro-cancer effects of androgens and androgen receptor. The classical role for sGCα1 is to heterodimerize with the sGCβ1 subunit, forming sGC, the enzyme that mediates nitric oxide signaling by catalyzing the synthesis of cyclic guanosine monophosphate. Our publ...
