The oncogene erbB-2 codes for a receptor tyrosine kinase that functions as a key mitotic signal in a variety of cell types. Amplification or overexpression of erbB-2 occurs in many forms of cancer, such as of the breast, colon, and prostate, and is an indicator of poor prognosis in those diseases. In the human prostate cancer cell lines LNCaP and PC-3, erbB-2 kinase was activated by pesticides ...

Aims: To investigate the effect of parthenolide on nucleolin in controlling expression miR-375 that induces apoptosis and cell cycle arrest prostate cancer.
 Study Design: This study is an experimental study.
 Methodology: The cytotoxicity was tested by MTT assay for 48 h. Microscopic techniques were used to identify morphological changes line. apoptotic regulatory genes analyzed Real...

The proteasome inhibitor, bortezomib, has been demonstrated to sensitize tumor cells to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis. Natural killer (NK) cells represent potent antitumor effector cells. They also express TRAIL. Therefore, we investigated whether bortezomib could sensitize tumor cells to NK cell-mediated killing, and have the same effect in ...

The prostate has been identified as a target for 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)-induced carcinogenesis. Humans are exposed to PhIP through ingestion of well-done cooked meats, and there is evidence from epidemiological studies that implicates red meat consumption in prostate carcinogenesis. The alpha and pi class isoforms of glutathione S-transferases (GSTs) have been sh...

objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...

background: erythropoietin (epo) is a glycoprotein hormone function to regulate the production of red blood cells. deficiency of epo is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. availability of recombinant epo has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. glycosylation of e...

Limited treatment options are available for aggressive prostate cancer. Gossypol has been reported to have a potent anticancer activity in many types of cancer. It can increase the sensitivity of cancer cells to alkylating agents, diminish multidrug resistance and decrease metastasis. Whether or not it can induce autophagy in cancer cells has not yet been determined. Here we investigated the an...
