Decremental effect of non-host humoral milieu interfacing viral envelope on the RNA level and surface antigenicity of hepatitis C virus (HCV) in vitro

Conclusion: This study clearly shows that the non-host humoral milieu such as mouse, and DMEM decreases the RNA level and surface antigenicity, clinically implying the decremental infectivity of HCV virions. This is the frst note to tune HCV viability via conditioning only host humoral milieu free of genetic approach.

MicroRNA-122 (miR-122) is highly expressed in hepatocytes, where it plays an important role in regulating cholesterol and fatty acid metabolism, and it is also a host factor required for hepatitis C virus replication. miR-122 is selectively stabilized by 3′ adenylation mediated by the cytoplasmic poly(A) polymerase GLD-2 (also known as PAPD4 or TENT2). However, it is unclear how GLD-2 specifically stabilizes miR-122. Here, we show that QKI7 KH domain-containing RNA binding (QKI-7), one of three isoforms of the QKI proteins, which are members of the signal transduction and activation of RNA (STAR) family of RNA-bindin...

o Binder Chronic Hepatitis C virus (HCV) infection still constitutes a major global health problem with almost half a million deaths per year. To date, the human hepatoma cell line Huh7 and its derivatives is the only cell line that robustly replicates HCV. However, even different subclones and passages of this single cell line exhibit tremendous differences in HCV replication efficiency. By comparative gene expression profiling using a multi-pronged correlation analysis across eight different Huh7 variants, we identified 34 candidate host factors possibly affecting HCV permissiveness. For seven of the candidates, we c...

ConclusionBupleuri Radix/Curcumae Radix medicine pair may have an effect on the procedure of programmed death and apoptosis and lipid metabolism. PIK3CG, BCL2, CASP3, MMP1 and CASP8 may play a key role in the treatment of hepatitis C. The two medicines may work on those targets and have an effect on hepatitis C.

In conclusion, we studied the incidence of OCI in Iranian patients with hemophilia for the first time. Our results demonstrated that unfavorable genotypes of IFNL3 SNPs and IFNL4 ss469415590 have a strong relationship with OCI positivity. It seems that the host immune response plays a vital role in OCI positivity. PMID: 31838260 [PubMed - as supplied by publisher]

Hepatitis C virus clearance and less liver damage in patients with high cholesterol, low-density lipoprotein cholesterol and APOE ε4 allele. World J Gastroenterol. 2019 Oct 14;25(38):5826-5837 Authors: Gonzalez-Aldaco K, Roman S, Torres-Valadez R, Ojeda-Granados C, Torres-Reyes LA, Panduro A Abstract BACKGROUND: Cholesterol is related to improvements in the rate of sustained virological response and a robust immune response against the hepatitis C virus (HCV). APOE gene polymorphisms regulate cholesterol levels modifying the course of the HCV infection. The relationship between cholesterol, AP...

This study elicited the preferences of CHC patients for treatment attributes of new DAAs.MethodsAn online discrete choice experiment survey was designed to collect data from adult CHC patients in the USA, UK, France, Germany, Spain, and Italy. Patients were asked to choose from alternative hypothetical DAA options, defined by differing levels of nine attributes [i.e., treatment duration, tablet count and packaging, cure rate, required office visits when on treatment, modifications to statins or to proton pump inhibitors (PPIs), and risks of diarrhea, headache and nausea]. Logistic regression was used to assess preference f...

Authors: González-Aldaco K, Torres-Reyes LA, Ojeda-Granados C, José-Ábrego A, Fierro NA, Román S Abstract Hepatitis C virus (HCV) is a lipid-enveloped virion particle that causes infection to the liver, and as part of its life cycle, it disrupts the host lipid metabolic machinery, particularly the cholesterol synthesis pathway. The innate immune response generated by liver resident immune cells is responsible for successful viral eradication. Unfortunately, most patients fail to eliminate HCV and progress to chronic infection. Chronic infection is associated with hepatic fat accumulation...
