Splet09. jul. 2024 · In the direct pathway, endogenous or exogenous materials directly contact DNA, leading to the breakage of chemical bonds in DNA molecules, and thereby changing the structure and activity of DNA.... SpletDNA damage repair (DDR) mechanisms have been implicated in a number of neurodegenerative diseases (both genetically determined and sporadic). Consistent with this, recent genome-wide association studies in Huntington’s disease (HD) and other trinucleotide repeat expansion diseases have highlighted genes involved in DDR …

Splet28. maj 2024 · p21Waf/CIP1 is a small unstructured protein that binds and inactivates cyclin-dependent kinases (CDKs). To this end, p21 levels increase following the activation of the p53 tumor suppressor. CDK inhibition by p21 triggers cell-cycle arrest in the G1 and G2 phases of the cell cycle. In the absence of exogenous insults causing replication stress, … Spletlines through gaps in the cGAS pathway. We demonstrate that SETD8's ability to promote DNA virus replication is determined by its enzyme activity. Our findings also indicate that PCNA stability, an essential component of viral DNA replication, depends on SETD8. The stimulation of SETD8 ...
