Peptide YY inhibits transcription and replication of hepatitis B virus by suppressing promoter/enhancer activity.
Hepatitis B virus (HBV) infection is a noteworthy cause of liver diseases, especially cirrhosis and hepatocellular carcinomas. However, the interaction between the host and HBV has not been fully elucidated. Peptide YY (PYY) is a 36-amino-acid gastrointestinal hormone that is mainly involved in the regulation of the human digestive system. This study found that PYY expression was reduced in HBV-expressing hepatocytes and HBV patients. Overexpression of PYY could significantly inhibit HBV RNA, DNA levels, and the secretion of HBsAg. In addition, PYY inhibits HBV RNA dependent on transcription through reducing the activities of CP/Enh I/II, SP1 and SP2. Meanwhile, PYY blocks HBV replication independent on core, polymerase protein and ε structure of pregenomic RNA. These results suggest that PYY can impair HBV replication by suppressing viral promoters/enhancers in hepatocytes. Our data shed light on a novel role for PYY as anti-HBV restriction factor.
期刊介绍：
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
