Human REXO4 is Required for Cell Cycle Progression.

Unlabelled: Human REXO4 is a poorly characterized exonuclease that is overexpressed in human cancers. To better understand the function of REXO4 and its relationship to cellular proliferation, we have undertaken multidisciplinary approaches to characterize its cell cycle phase-dependent subcellular localization and the cis determinants required for this localization, its importance to cell cycle progression and cell viability, its protein-protein association network, and its activity. We show that the localization of REXO4 to the nucleolus in interphase depends on an N-terminal nucleolar localization sequence and that its localization to the perichromosomal layer of mitotic chromosomes is dependent on Ki67.

"Todes" and "Todxs", linguistic innovations or grammatical gender violations?

This study compared the processing of non-binary morphemes in Spanish (e.g., todxs, todes) with the processing of canonical grammatical gender violations in Spanish pronouns (e.

Epicardial adipose tissue, cardiac damage, and mortality in patients undergoing TAVR for aortic stenosis.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Absence of MCJ/DnaJC15 promotes brown adipose tissue thermogenesis.

Obesity poses a global health challenge, demanding a deeper understanding of adipose tissue (AT) and its mitochondria. This study describes the role of the mitochondrial protein Methylation-controlled J protein (MCJ/DnaJC15) in orchestrating brown adipose tissue (BAT) thermogenesis. Here we show how MCJ expression decreases during obesity, as evident in human and mouse adipose tissue samples.

Brief communication: gaps and opportunities in HIV research in Venezuela.

Over the past decade, Venezuela has experienced a political and economic crisis that has affected the country's scientific research development. Currently, the state of HIV research in Venezuela remains unknown. We conducted a systematic review identifying 683 articles over the last 20 years of which only 101 met our inclusion criteria.
