miR-21 represses Pdcd4 during cardiac valvulogenesis.
The discovery of small non-coding microRNAs has revealed novel mechanisms of post-translational regulation of gene expression, the implications of which are still incompletely understood. We focused on microRNA 21 (miR-21), which is expressed in cardiac valve endothelium during development, in order to better understand its mechanistic role in cardiac valve development. Using a combination of i...
متن کاملmiR-21 promotes migration and invasion by the miR-21-PDCD4-AP-1 feedback loop in human hepatocellular carcinoma.
Distant migration and invasion is the main contributor to the death of cancer patients and miRNAs have been implicated in these processes. In the present study, we identified the role of microRNA-21 (miR-21) in hepatocellular carcinoma (HCC) migration and invasion and determined its underlying regulatory mechanism. miR-21 was significantly upregul...
متن کاملERK8 is a novel HuR kinase that regulates tumour suppressor PDCD4 through a miR-21 dependent mechanism.
Programmed cell death 4 (PDCD4) is a tumour suppressor implicated in cancer development and progression and was recently identified as a repressor of cap-independent translation of specific genes involved in the regulation of apoptosis. We show that the RNA-binding protein HuR binds to the PDCD4 3'UTR to protect it from miR-21-induced silencing. However, following H2O2 treatment, PDCD4 mRNA is ...
متن کاملMiR-499-5p protects cardiomyocytes against ischaemic injury via anti-apoptosis by targeting PDCD4
Recent studies have reported that miRNAs might play critical roles in acute myocardial infarction (AMI). The objective of this study is to investigate the role of miR-499-5p in AMI and its potential molecular mechanisms. The expression level of MiR-499-5p was remarkably decreased in the infarcted myocardial tissues and in the cultured neonatal rat cardiomyocytes induced by hypoxia. Overexpressi...
متن کاملIL-6 Inhibits the Targeted Modulation of PDCD4 by miR-21 in Prostate Cancer
Prostate cancer is the most common cancer among men in the Unites States. The cytokine IL-6 activates several prostate cancer pathways, but its upstream trans-signaling pathway remains poorly understood. In this study, we evaluated the role of IL-6 in PDCD4 gene expression and how the microRNA miR-21 regulates this process in prostate cancer cell lines PC-3 and LNCaP. The expression pattern of ...
