Super-enhancer Activates Master Transcription Factor NR3C1 Expression and Promotes 5-FU Resistance in Gastric Cancer.

Poor response to 5-fluorouracil (5-FU) remains an obstacle in the treatment of gastric cancer (GC). Super enhancers (SEs) are crucial for determining tumor cell survival under drug pressure. SE landscapes related to 5-FU-resistance are mapped to GC using chromatin immunoprecipitation-sequencing (ChIP-Seq).

Mutation of lysine-specific demethylase 5 is associated with enhanced tumor immunity and favorable outcomes in pan-cancer immune checkpoint blockade.

The lysine-specific demethylase 5 (KDM5) family, a key post-translational modification of chromatin, can shape tumor immune microenvironment. Here, we performed an extensive clinical and bioinformatic analysis to explore the association between KDM5 mutation and tumor immunity and its impact on the outcomes in pan-cancer immunotherapy. In 2943 patients across 12 tumor types treated with immune checkpoint inhibitors, KDM5-mutant tumors were associated with favorable overall survival (hazard ratio, 0.

Leadless pacemaker implantation after delayed atrial lead perforation and battery depletion: a case report.

Background: Delayed lead perforation is a rare complication of cardiac implantable electronic device (CIED). Clinical presentations range from completely asymptomatic to pericardial tamponade. Surgical lead extraction is recommended and transvenous lead extraction (TLE) with surgical backup is an alternative method.

New Contributions on Species Diversity of Genus and s.l. in China.

Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera and sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU- phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz.

Two sides of the same coin: Weathering differences of plastic fragments in coastal environments around the globe.

Plastic debris in coastal environments usually undergoes weathering due to various environmental conditions. However, the weathering effects on exposed and shaded sides of the same plastics are underexplored. In this study, 1573 plastic fragments were collected from 15 coastal sites worldwide between December 2021 and December 2022, and weathering experiments were conducted outdoors.
