WebJun 21, 2013 · Introduction. Host cell reactivation (HCR) of damaged reporter genes has long been used to examine the DNA repair capacity of different cell types ().The specific repair pathway examined is determined by the agent used to damage the DNA of the reporter construct. WebDuring reactivation from latency, gammaherpesviruses radically restructure their host cell to produce virion particles. To achieve this and thwart cellular defenses, they induce rapid degradation of cytoplasmic mRNAs, suppressing host gene expression. ...

WebSteps of Virus Infections. A virus must use its host-cell processes to replicate. The viral replication cycle can produce dramatic biochemical and structural changes in the host cell, which may cause cell damage. These changes, called cytopathic effects, can change cell functions or even destroy the cell.

WebJul 23, 2024 · After a virus invades the host cell, the host produces a corresponding stress response that stimulates stress kinases (GCN2, PKR, PERK, HRI), which affect eIF2α phosphorylation. Among these kinases, GCN2 and PKR have antiviral effects in the viral infection process. PERK plays a role in ER stress caused by viral protein synthesis, and … WebApr 7, 2024 · Host-cell reactivation of reporter constructs containing synthetic dG(C8)-AAF and TT dimer (T T), as NER substrates processed by both TC-NER and GG-NER, is shown for comparison.

WebMost viruses use host cell proteins to repair and replicate. Taking advantage of this, a repair assay was designed to use the ability of UV-damaged viruses or plasmids to replicate in host cells as an indicator of the host repair capacity. This forms the basis for the host replication-dependent Host Cell Reactivation assay (83–88).
