مقدمه: پدیده گذر از اپیتلیال به مزانشیم(emt) پدیده رایجی است که در اکثر سرطانهایی که منشاء اپیتلیالی دارند، رخ می دهد و کاهش بیان ژن cdh1 در القاء این پدیده نقش موثری دارد. از آنجایی که عوامل اپی ژنتیکی در تنظیم بیان این ژن دخیل می باشند، در این مطالعه تغییرات هیستونی در ناحیه تنظیمی ژن cdh1 در سلول های کارسینومای جنینی (eccs) و سلول های بنیادی و غیر بنیادی سرطان پروستات مورد بررسی قرار گرفت. ...
زمینه و هدف: یکی از علل اصلی مرگ ومیر ناشی از سرطان در مردان، سرطان پروستات می باشد. روش های درمانی متفاوتی برای درمان سرطان پروستات وجود دارد؛ اما بسیاری از بیماران مبتلا به سرطان پروستات از عود بیماری پس از عمل و متاستاز رنج می برند. افزایش بیان 1 hmga2، یک پروتئین انکوژن، در انواع مختلف تومورهای بدخیم از قبیل سرطان کولورکتال، تیروئید، پانکراس، ریه با پیشرفت تومور همراه است. هدف از این مطالعه...
The p53-inducible gene PC3 (TIS21, BTG2) is endowed with antiproliferative activity. Here we report that expression of PC3 in cycling cells induced accumulation of hypophosphorylated, growth-inhibitory forms of pRb and led to G(1) arrest. This latter was not observed in cells with genetic disruption of the Rb gene, indicating that the PC3-mediated G(1) arrest was Rb dependent. Furthermore, (i) ...
Bone is a major site of metastasis for several types of malignant tumor. Specific interactions between tumor cells and the bone microenvironment contribute to the tendency of tumors to metastasize to bone. Furthermore, Wnt5a participates in the progression of several types of malignant tumor. This study investigates the role of Wnt5a in the migration of the prostate cancer (PCa) cell line PC3 t...
We assessed the capability of paclitaxel, one of the taxanes, to induce death in two prostate cancer lines, LNCaP and PC3. Paclitaxel drove an apoptotic pathway in LNCaP, but not in PC3 cells, in response to G2/M arrest. An examination of the levels of anti-apoptotic proteins revealed that Bcl-xl was much higher in PC3 cells than in LNCaP cells and Bcl2 could be detected only in PC3 cells, not ...
Drugs that target the tumor vasculature and inhibit angiogenesis are widely used for cancer treatment. Individual tumors show large differences in vascularity, but it is uncertain how these differences affect responsiveness to antiangiogenesis. We investigated this question using two closely related prostate cancer models that differ markedly in tumor vascularity: PC3, which has very low vascul...

BACKGROUND It is extensively supposed that vegetarian diet could affect cancer progress and increase the influence of formal chemotherapy. OBJECTIVES The present study was designed to determine the effect of the ethanol Bane skin extract against chemo resistant prostate cancer PC3 cells. MATERIALS AND METHODS PC3 and L929 cells were cultivated and then incubated in the ethanol Bane skin ext...
BACKGROUND Tumour-derived extracellular vesicles (EVs) play a role in tumour progression; however, the spectrum of molecular mechanisms regulating EV secretion and cargo selection remain to be fully elucidated. We have reported that cavin-1 expression in prostate cancer PC3 cells reduced the abundance of a subset of EV proteins, concomitant with reduced xenograft tumour growth and metastasis. ...
