Notoginsenoside R1 inhibits hepatitis B virus replication by modulating SIRT1 activity
Acta Virologica
|March 23, 2023
Summary
Notoginsenoside R1 effectively suppresses hepatitis B virus (HBV) replication. This occurs by reducing sirtuin 1 (SIRT1) activity, showing therapeutic potential for HBV infection.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Hepatitis B virus (HBV) infection is a significant global health concern.
- Notoginsenoside R1, known for its pharmacological effects, is explored for HBV treatment.
Purpose of the Study:
- To investigate the therapeutic potential of notoginsenoside R1 against HBV infection.
- To elucidate the mechanism underlying notoginsenoside R1's effect on HBV replication.
Main Methods:
- Utilized HBV-positive hepatocellular carcinoma cell lines (HepG2, MHCC97H).
- Assessed HBV DNA, surface antigen, core antigen, and SIRT1 levels via RT-qPCR and Western blotting.
- Employed an HBV hemodynamic replication model and animal experiments for in vivo validation.
Main Results:
- Notoginsenoside R1 demonstrated significant inhibition of HBV replication.
- The inhibitory effect was linked to the downregulation of sirtuin 1 (SIRT1) activity.
- Inhibition of SIRT1, through silencing or using selisistat, also suppressed HBV replication.
Conclusions:
- Notoginsenoside R1 suppresses HBV replication both in vitro and in vivo.
- The mechanism involves the downregulation of SIRT1 activity.
- Notoginsenoside R1 presents a promising therapeutic candidate for hepatitis B virus infection.

siRNA - Small Interfering RNAs
16.9K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Experimental RNAi
6.2K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Viruses with RNA Genomes
63
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Eukaryotic Transcription Inhibitors
9.9K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...
