Phase separation of ERCC6L2-CtIP regulates the extent of DNA end resection.

The ataxia telangiectasia mutated (ATM) kinase orchestrates the early stages of DNA double-strand break repair by promoting hyperphosphorylation of CtIP, a key step in the initiation of DNA end resection. However, the regulatory mechanisms controlling resection extent remain incompletely understood. Here we identify ERCC6L2 as a key regulator of DNA end resection in response to ATM inhibition.

An end-to-end multifunctional AI platform for intraoperative diagnosis.

Intraoperative frozen section diagnosis provides essential, real-time histological insights to guide surgical decisions. However, the quality of these time-sensitive sections is often suboptimal, posing significant diagnostic challenges for pathologists. To address these limitations, we utilized over 6700 whole slide images to develop GAS, a comprehensive platform comprising three modules: Generation, Assessment, and Support modules.

Telomere-to-telomere gapless genome assembly of the Chinese sea bass (Lateolabrax maculatus).

Chinese sea bass (Lateolabrax maculatus) is a highly sought-after commercial seafood species in Asian regions due to its excellent nutritional value. With the rapid advancement of bioinformatics, higher standards for genome analysis compared to previously published reference genomes are now necessary. This study presents a gapless assembly of the Chinese sea bass genome, which has a length of 632.

Transcriptomic analysis and expression of C-type lectins in response to Vibrio parahaemolyticus challenge in Scapharca subcrenata.

Little information is available on innate immune defense mechanisms of Scapharca subcrenata. C-type lectins (CTLs) are not only pattern recognition proteins that can bind pathogen-associated molecular patterns, but also crucial maternally-derived immune factors in mollusc egg. In this study, the comparative transcriptome analysis of Vibrio parahaemolyticus-infected and untreated hepatopancreas were performed to identify the key genes involved in maternal transfer of immunity.
