Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

DNA methylation plays an important role in silencing transposable elements. Here the authors find that loss of DNMT1 and DNA methylation leads to transcriptional activation and chromatin remodelling of evolutionarily young—hominoid-specific —LINE-1 ...

Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Endosymbiotic ratchet accelerates divergence after organelle origin
Primary endosymbiosis gave rise to mitochondria and plastids. The proximate impacts of organelle origin on lineage evolution have not been addressed at the population level. Using data from the photosynthetic amoeba Paulinella, we hypothesize that primary endosymbiosis accelerates lineage divergence, a process we refer to as the endosymbiotic ratchet ...

LTR-retrotransposons in R. exoculata and other crustaceans [PDF]
Transposable elements are major constituents of eukaryote genomes and have a great impact on genome structure and stability. They can contribute to the genetic diversity and evolution of organisms. Knowledge of their distribution among several genomes is

This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

Insecticide use is pervasive as a selective force in modern agroecosystems. Insect herbivores exposed to these insecticides have been able to rapidly evolve resistance to them, but how they are able to do so is poorly understood. One possible but largely

CINs of the cytoplasm: dissecting dsRNA signaling in chromosomal instability
Micronuclei, formed during cell division in chromosomal instability settings, rupture and lead to the accumulation of immunogenic double‐stranded RNA in the cytoplasm, activating MAVS‐dependent interferon signaling and innate antitumor immunity.

A powerful global test for spliceQTL effects
Abstract Statistical methods to test for effects of single nucleotide polymorphisms (SNPs) on exon inclusion exist but often rely on testing of associations between multiple exon–SNP pairs, with sometimes subsequent summarization of results at the gene level. Such approaches require heavy multiple testing corrections and detect mostly events with large

Identification of structural variation in mouse genomes. [PDF]
Structural variation is variation in structure of DNA regions affecting DNA sequence length and/or orientation. It generally includes deletions, insertions, copy-number gains, inversions, and transposable elements.
