WebGlobal transcription from cryptic TSSs after treatment We hypothesized that the aberrant activation of cryptic TSSs is not restricted to the DAPK1 locus but a global … WebApr 6, 2024 · Although histone methylation decreased overall in senescent cells, the team observed a specific pattern of increased methylation on histone 3. This pattern is normally seen at the start sites of transcription at sequences known as promoters and provides further support that epigenetic changes drive cryptic transcription.

WebMar 19, 2009 · Alternatively, sites of cryptic transcription could be distributed arbitrarily relative to length and transcription rate, but still represent functional internal promoters … WebDec 2, 2016 · By using a previously described reporter cell line for epigenetic reactivation of the DAPK1 locus, we have shown that epigenetic treatment causes transcription from uncharacterized intronic transcription start sites (TSSs), thereby generating DAPK1 mRNA with novel first exons.
WebMar 9, 2024 · Set2 methylation normally functions to suppress cryptic transcription, which can be sense or antisense to normal transcription [19,20,46,47]. We hypothesized that activation of cryptic antisense transcription in a set2 Δ (or H3K36A) mutant would stimulate repair of the NTS through the TC-NER pathway, thereby restoring UV resistance.

WebSep 23, 2010 · The Set2-Rpd3S pathway is important for the control of transcription memory. Mutation of components of this pathway results in cryptic transcription initiation within the coding region of approximately 30% of yeast genes.
