The aim of this study is to address the role of phosphorylated mTOR (p-mTOR) in prostate adenocarcinoma-induced lymphangiogenesis and lymph node metastasis as well as to investigate its relationship with chicken ovalbumin upstream promoter transcriptional factor 2 (COUP-TFII) and the vascular endothelial growth factors A/C (VEGF A/C).
Artificial overexpression of miR-199a-5p decreased cell proliferation, motility, and tumor angiogenesis and increased apoptosis in PCa cell liness PC-3 and DU145 by directly targeting the 3'-untranslated region (UTR) of HIF-1α mRNA, which reduced HIF-1α levels as well as downstream genes transactivated by HIF-1α (such as VEGF, CXCR4, BNIP3 and BCL-xL).
Although basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) have been characterized as promoters of angiogenesis, their precise localization in prostatic adenocarcinoma remains unclear.
Human prostate and bladder cancers (prostatic adenocarcinoma and transitional cell carcinomas) were evaluated for VEGF mRNA expression by in situ hybridization.
