Summary from the GEO: "We report that the protein encoded by the SMARCB1 gene, SNF5, is capable of inhibiting MYC binding in vitro and in a malignant rhabdoid tumor (MRT) cell line. By comparing the effects of reintroduction of SNF5 with genetic inhibition of MYC (OMOMYC) on multiple aspects of chromatin remodeling and transcription in MRT cells, we show that regulation of MYC binding by SNF5 is not...

Summary from GEO: "The phosphoinositide 3-kinase (PI3K) pathway integrates extracellular stimuli to phosphorylate and activate key downstream effectors such as AKT and serum-and glucocorticoid-inducible kinase (SGK1). We have previously reported that the PI3K pathway regulates ER-dependent transcription in breast cancer through the phosphorylation of the epigenetic regulator KMT2D by AKT. Here, we...

Summary from GEO: "Chromosomal instability (CIN) and epigenetic reprograming are characteristic of advanced and metastatic human cancers, yet whether they are mechanistically linked is unknown. Here we show that missegregation of mitotic chromosomes, their sequestration in micronuclei, and subsequent micronuclear envelope rupture significantly disrupt normal histone post-translational modifications,...

Summary from GEO: "We show that ligation-competent Okazaki fragments in Saccharomyces cerevisiae are sized according to the chromatin repeat. Using deep sequencing, we demonstrate that ligation junctions preferentially occur around nucleosome midpoints rather than in internucleosomal linker regions. Disrupting chromatin assembly or lagging strand polymerase processivity impacts both the size and...
