ENOCs were divided by cases with microsatellite instability (28%), with a distinct mismatch-repair mutation signature. Taken together, our work establishes the potency of the somatic genome, reflective of diverse DNA repair deficiencies, to stratify ovarian cancers into distinct biological strata ...

Mechanisms of nuclear trafficking mediated by NLS A schematic model for nuclear protein import through NPC illustrates how can a complex biological function can be generated by a spatially and temporally organized cycle of interactions between cargoes, carriers and Ran GTPase [46]. NLS-dependent protei...
Learn about double-strand break repair, including what causes double- and single-strand breaks in DNA. Review repair mechanisms for DNA double-strand breaks. Updated: 11/21/2023 Table of Contents Double-Stranded Break Repair DNA Double-Strand Break Repair by Homologous Recombination DNA Double-...
IV- Regulation at the level of Translation: Most eukaryotic translational controls affect the initiation ofprotein synthesis, the initiation factors for translation, particularly eukaryotic initiation factor 2(eIF2), are the focus of these regulatory mechanisms, the action of eIF2 can be inhibite...
Identifying genes that specifically regulate this process is difficult due to the proliferative state of GC B cells and the associated DNA repair mechanisms inherent in any proliferating cell. By using the CL, we identified similar cell types that are proliferating and then subtracted any shared up...
Therefore, ionizing radioresistant organisms have developed all, or a combination of different strategies like the novel and adaptive DNA repair mechanisms, antioxidant and enzymatic defense systems, and a condensed nucleoid. Fast and accurate repair of genomes is essential in surviving doses of ionizin...
Citation6 Additionally, SPP1’s role in the tumor microenvironment has garnered significant attention, as it is involved in immune cell infiltration, cytokine secretion, and immune evasion mechanisms.Citation5,Citation7 However, the expression characteristics of SPP1 in gliomas and its potential as a...
Cell-intrinsic regulatory mechanisms of OPC function include genetic and epigenetic factors that control their proliferation, differentiation, and survival. Interestingly, in artificial cell culture environments, OPCs proliferate indefinitely and only become senescent when exposed to genotoxic drugs [77]. In...
is added to dna is called dna methylation. methylation helps regulate gene expression by repressing transcription. this activity changes genetic function without altering dna sequences and is one of many epigenetic mechanisms. gene expression processes attributed to dna methylation include genomic ...
