Mismatch repair (MMR) enzymes have been shown to be deficient in prostate cancer (PCa). MMR can influence the regulation of tumor development in various cancers but their role on PCa has not been investigated. The aim of the present study was to determine the functional effects of the mutL-homolog 1 (MLH1) gene on growth of PCa cells. The DU145 cell line has been established as MLH1-deficient a...
BACKGROUND Prostate cancer initially develops in an androgen-dependent manner but, during its progression, transitions to being androgen-independent in the advanced stage. Pin1, one of the peptidyl-prolyl cis/trans isomerases, is reportedly overexpressed in prostate cancers and is considered to contribute to accelerated cell growth, which may be one of the major factors contributing to their an...
KAI1/CD82 protein is a member of the tetraspanin superfamily and has been rediscovered as a cancer metastasis suppressor. The mechanism of KAI1/CD82-mediated suppression of cancer metastasis remains to be established. In this study, we found that migration of the metastatic prostate cancer cell line Du145 was substantially inhibited when KAI1/CD82 was expressed. The expression of focal adhesion...
AIM OF THE STUDY To explore the mechanism of oxidative stress in the development of prostate cancer, here we compared 4-hydroxynonenal (4-HNE)- treated LNCaP (hormone-sensitive) and DU145 (hormone insensitive) cells with significant differences in sensitivity to androgen. MATERIAL AND METHODS The prostate cancer cell line LNCaP and late cell line DU145 were treated with different concentratio...
An increasing number of malignancies has been shown to be initiated and propelled by small subpopulations of cancer stem cells (CSC). However, whether tumor aggressiveness is driven by CSC and by what extent this property may be relevant within the tumor mass is still unsettled. To address this issue, we isolated a rare tumor cell population on the basis of its CD44(+)CD24(-) phenotype from the...
the purpose of this study is to investigate the effects of quercetin as an inhibitor of heat shock proteins and hyperthermia on the induced dna damages and colony formation ability of du145 tumor spheroid culture. du145 cells were cultured as spheroids. on day11, spheroids with mean diameter 100 μm were treated with different concentration of quercetin for 24 hours and then exposed to hyperther...
Cyclic Arg-Gly-Asp-D-Phe-Lys [c(RGDfK)] targeted poly(L-glutamic acid) (PGA)-(Gd-DO3A) conjugate with a biodegradable cystamine spacer was prepared and evaluated for in vivo detection of an angiogenesis biomarker, alpha(v)beta3 integrin, in neoplastic tissues with T1 mapping, a quantitative magnetic resonance imaging (MRI) technique. The binding activity of the c(RGDfK) containing conjugate was...
shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
زمینه و هدف: ساخت و ترکیب داروهای جدید گیاهی و شیمیایی علیه بیماری هایی مثل سرطان، از جمله تلاش های مهم سال های اخیر محسوب می شود. ترکیبات ترپنی از جمله ترکیبات مهمی هستند که خواص بیولوژیکی و فارماکولوژیکی متعددی دارند، اما به دلیل حلالیت کم آن ها در محلول های آبی کمتر مورد توجه بوده اند. سیکلودکسترین ها نیز نانوکپسول های طبیعی تشکیل شده از واحدهای گلوکزی هستند که می توانند ایجاد نانوحفره نماین...
