p27 is a cyclin-dependent kinase inhibitor that regulates the progression of cells from G(1) to S phase of the cell cycle. Loss of p27 has been associated with disease progression and with an unfavourable outcome in prostate cancer. In this study, we investigated whether exogenous p27 expression in the human androgen-independent prostate cancer PC3 cell line had any effect on cell growth, and w...
Calponin is an actin filament-associated protein and its h2 isoform inhibits cell motility. Here we report significant expression of h2-calponin in prostate epithelial cells, which is diminished in cancerous cells. Comparison between a prostate cancer cell line PC3 and its metastatic derivative PC3-M showed lower levels of h2-calponin in PC3-M, corresponding to faster rates of cell proliferatio...
زمینه و هدف: امروزه، سرطان ها یکی از بزرگترین نگرانی های جوامع بشری است. ترکیبات پلی فنلی و آنتی اکسیدان ها به عنوان یک فاکتور مهم و کلیدی در پیشگیری و یا درمان انواع سرطان ها به خوبی معرفی شده اند. این تحقیق با هدف بررسی اثر کارواکرول به عنوان یک ماده آنتی اکسیدانی قوی بر مهار رشد و میزان تخریب ژنوم رده سلول سرطانی PC3 پروستات انجام شده است. روش بررسی: در این مطالعه تجربی آزمایشگاهی، سلول های...
Previously, we found a positive correlation between the expression of platelet-type 12-lipoxygenase (12-LOX) and the progression of human prostate adenocarcinoma (PCa; Gao et al., Urology, 46: 227-237, 1995). To determine the role of 12-LOX in PCa progression, we generated stable 12-LOX-transfected PC3 cells, which synthesize high levels of 12-LOX protein and 12(S)-hydroxyeicosatetraenoic acid ...
سابقه و هدف: تریسین به عنوان یک ترکیب فلاوونی در بسیاری منابع غذایی، دارای اثرات ضد التهابی و ضد تکثیری در برخی ردههای سلولی سرطانی میباشد. با توجه به اهمیت استفاده از داروهای طبیعی با خواص ضد سرطانی در سرطانهای مقاوم به درمان همچون سرطان پروستات، هدف از مطالعه حاضر بررسی اثر تریسین بر رشد و تکثیر سلولی و القای آپوپتوز در رده سلولی سرطان پروستات انسانی PC3 می باشد. مواد و روشها: در این مطال...
Background & Objective: Herbal medicine and their composition are widely used for different therapeutic purposes. Therefore, this study was designed to evaluate of the anti-proliferation and anti-migration effects of Thymoquinone (TQ), an active part of Nigella sativa, on PC3 prostate cancer cells. Materials & Methods: In this experimental study, PC3 prostate cancer cells were treated with 0, 1...
BTG2/TIS21/PC3 (B cell translocation gene 2) has been known as a p53 target gene and functions as a tumor suppressor in carcinogenesis of thymus, prostate, kidney, and liver. Although it has been known that the expression of BTG2/TIS21/PC3 is induced during chemotherapy-mediated apoptosis in cancer cells, a role of BTG2/TIS21/PC3 in cell death remains to be elucidated. In this study, the mechan...
Zinc ions (Zn2+) are known to influence cell survival and proliferation. However the homeostatic regulation of Zn2+ and their role in prostate cancer (PC) progression is poorly understood. Therefore the subcellular distribution and uptake of Zn2+ in PC cells were investigated. Inductively coupled plasma mass spectroscopy and fluorescent microscopy with the Zn2+-specific fluorescent probe FluoZi...
PC3, a mammalian homologue of the yeast subtilisin-like proteinase Kex2, was expressed in Xenopus oocytes and its activity was characterized. PC3 cleaved human proinsulin at one of the two dibasic sites (KTRR32 but not LQKR65). The specificity, inhibitor profile, pH optimum (5.5) and Ca(2+)-dependence (K0.5 = 2.5-3 mM) paralleled those of the insulin-granule type 1 endopeptidase activity, sugge...
Growing evidence indicates that cell cycle arrest and neurogenesis are highly coordinated and interactive processes, governed by cell cycle genes and neural transcription factors. The gene PC3 (Tis21/BTG2) is expressed in the neuroblast throughout the neural tube and inhibits cell cycle progression at the G1 checkpoint by repressing cyclin D1 transcription. We generated inducible mouse models i...
