Hepatitis C virus genetics affects miR-122 requirements and response to miR-122 inhibitors
Hepatitis C virus (HCV) replication is dependent on a liver-specific microRNA (miRNA), miR-122. A recent clinical trial reported that transient inhibition of miR-122 reduced viral titres in HCV-infected patients. Here we set out to better understand how miR-122 inhibition influences HCV replication over time. Unexpectedly, we observed the emergence of an HCV variant that is resistant to miR-122...
متن کاملmiR-122-induced down-regulation of HO-1 negatively affects miR-122-mediated suppression of HBV.
As the most abundant liver-specific microRNA (miRNA), miR-122 has been extensively studied for its role in the regulation of lipid metabolism, hepatocarcinogenesis and hepatitis C virus (HCV) replication, but little is known regarding its role in the replication of Hepatitis B virus (HBV), a highly prevalent hepatotropic virus that can cause life-threatening complications. In this study we exam...
متن کاملOverexpression of miR-21 and miR-122 in preeclamptic placentas.
OBJECTIVE Preeclampsia is a pregnancy-associated disease with the impact of genetic, epigenetic and environmental factors. Increased apoptosis was observed in cells from preeclamptic placentas. MicroRNAs are involved in the regulation of apoptosis and are abundant in placenta. In this study, we focused on the analysis of differential gene expression of apoptosis-associated miRNAs in preeclampti...
متن کاملRegulation and biological function of the liver-specific miR-122.
miRNAs (microRNAs) are important regulators of gene expression. In higher eukaryotes, the tightly controlled expression of different miRNAs, each of which regulates multiple target mRNAs, is crucial for the maintenance of tissue type and the control of differentiation. miR-122 is a highly liver-specific miRNA that is important in hepatitis C virus infection, cholesterol metabolism and hepatocel...
متن کاملHepatitis C Virus RNA Functionally Sequesters miR-122
Hepatitis C virus (HCV) uniquely requires the liver-specific microRNA-122 for replication, yet global effects on endogenous miRNA targets during infection are unexplored. Here, high-throughput sequencing and crosslinking immunoprecipitation (HITS-CLIP) experiments of human Argonaute (AGO) during HCV infection showed robust AGO binding on the HCV 5'UTR at known and predicted miR-122 sites. On th...
