Prevalence of Naturally-Occurring NS5A and NS5B Resistance-Associated Substitutions in Iranian Patients With Chronic Hepatitis C Infection

Frontiers in Microbiology, 2021
BackgroundHepatitis C virus (HCV), non-structural 5A (NS5A), and non-structural 5B (NS5B) resistance-associated substitutions (RASs) are the main causes of failure to direct-acting antiviral agents (DAAs).

Hepatitis C virus 3'UTR regulates viral translation through direct interactions with the host translation machinery. [PDF]

, 2013
The 3' untranslated region (3'UTR) of hepatitis C virus (HCV) messenger RNA stimulates viral translation by an undetermined mechanism. We identified a high affinity interaction, conserved among different HCV genotypes, between the HCV 3'UTR and the host ...

Analysis of genetic polymorphisms and drug resistance mutations in the NS5 region of HCV genome (Flasuviricetes: Amarillovirales: Flaviviridae: Hepacivirus C) in samples obtained in 2022–2023 from HIV-infected treatment-naive residents of Altai Krai

Вопросы вирусологии
Introduction. Altai Krai is a region with an unfavorable situation of HIV-1 and HCV infection, as well as HIV-1 and HCV coinfection. Due to this, it is necessary to study the HCV genetic variants and their drug resistance (DR) to direct-acting antivirals
