objective: prostate cancer is the fifth most common cancer. in 2012, it was the second leading cause of cancer death for men worldwide. the pi3k/akt pathway plays an essential role in pathogenesis of prostate cancer; the key role of this pathway in cancer progression makes it an attractive target for prostate cancer therapy. micrornas (mirnas) that regulate gene expression have a special abilit...

BACKGROUND Chronic hepatitis C virus (HCV)-induced liver fibrosis involves upregulation of transforming growth factor (TGF)-β and subsequent hepatic stellate cell (HSC) activation. MicroRNAs (miRNAs) regulate HCV infection and HSC activation. METHODS TaqMan miRNA profiling identified 12 miRNA families differentially expressed between chronically HCV-infected human livers and uninfected contro...

PURPOSE Transforming growth factor β1 (TGFβ1) is very important in the synthesis and degradation of extracellular matrix (ECM) and also in the mediation of human orbital fibroblasts (OFs) proliferation. MicroRNA-29 (MiR-29) plays an important role in this process. In the present study, the effects of TGFβ1 on the expression of miR-29 and whether miR-29 is involved in pro-survival signaling path...

Background. Chronic Hepatitis C Virus (HCV) induced liver fibrosis is mediated by upregulation of Transforming Growth Factor (TGF)-beta and subsequent hepatic stellate cell (HSC) activation. MicroRNAs (miRNAs) regulate HCV infection and HSC activation. Methods. TaqMan miRNA profiling identified 12 miRNA families differentially expressed between chronically HCV-infected human livers and uninfect...

BACKGROUND Leukemia seriously threatens human life and health. MicroRNAs can regulate cell growth, proliferation, and death. This article investigated the role of miR-29 on regulating leukemia cell growth, proliferation, and apoptosis. MATERIAL AND METHODS miR-29 and scramble miRNA were transfected to K562 cells. MTT assay, colony formation assay, caspase-3 activity detection, and flow cytome...

MicroRNAs are essential for spermatogenesis. However, the stage-specific requirements for particular miRNAs in the male mammalian germ line remain largely uncharacterized. The miR-34 family is, to date, the only miRNA proven to be necessary for the production of sperm in mammals, though its germline roles are poorly understood. Here, we generate and analyze paired small RNA and mRNA profiles ac...

OBJECTIVE The goal of this study was to determine whether antagonizing microRNA (miR)-29 enhances elastin (ELN) levels in cells and tissues lacking ELN. METHODS AND RESULTS miR-29 mimics reduced ELN levels in fibroblasts and smooth muscle cells, whereas miR-29 inhibition increased ELN levels. Antagonism of miR-29 also increased ELN levels in cells from patients haploinsufficient for ELN and i...

MicroRNA molecules have been increasingly regarded as a diagnostic and prognostic marker of certain diseases. The aim of this study was to investigate the expression and clinical significance of miR-122 and miR-29 in liver disease related to hepatitis B virus infection. The serum levels of miR-122 and miR-29 in 20 patients with hepatocellular carcinoma (HCC), 20 patients with liver cirrhosis (L...

microRNAs (miRNAs) are non-coding RNAs which have the capacity to regulate gene expression at the post-transcriptional level, and have emerging as key factors involved in cancer at all stages ranging from initiation to metastasis. In the present review, we summmarize the diverse roles of the microRNA-29 (miR-29) family in cancer. First, we present a concise introduction to the miR-29 family and...
