N-acetyltransferase 10 (NAT10) is involved in regulating senescence. However, its role in glomerular diseases remains unclear. Therefore, this study aims to investigate the mechanisms by which NAT10 influences senescence and damage in an adriamycin (ADR)-induced nephropathy model. Senescence (p16 and p21) and DNA damage markers (γ-H2AX (ser139)) were assessed in ADR-induced nephropathy. NAT10 function was demonstrated using Remodelin or small interfering RNA (siRNA) interventions. Transcriptome...

Ferroptosis is closely linked with various pathophysiological processes, including aging, neurodegeneration, ischemia-reperfusion injury, viral infection and, notably, cancer progression; however, its post-translational regulatory mechanisms remain incompletely understood. Here we revealed a crucial role of S-palmitoylation in regulating ferroptosis through glutathione peroxidase 4 (GPX4), a pivotal enzyme that mitigates lipid peroxidation. We identified that zinc finger DHHC-domain containing...

The landscapes of somatic mutation in normal cells inform us about the processes of mutation and selection operative throughout life, providing insight into normal ageing and the earliest stages of cancer development¹. Here, by whole-genome sequencing of 238 microdissections² from 30 individuals, including 18 with gastric cancer, we elucidate the developmental trajectories of normal and malignant gastric epithelium. We find that gastric glands are units of monoclonal cell populations that accrue...

CONCLUSION: The study highlights the strong association between elder abuse, pain with depression, especially among older female. These findings underscore the need for targeted public health interventions among vulnerable groups such as older female, and future research to explore cross- national dynamics and underlying risk factors.

The hippocampus is a complex structure critically involved in numerous behavior-regulating systems. In young adults, multiple overlapping spatial modes along its longitudinal and transverse axes describe the organization of its functional integration with neocortex, extending the traditional framework emphasizing functional differences between sharply segregated hippocampal subregions. Yet, it remains unknown whether these modes (i.e. gradients) persist across the adult human lifespan, and...

Untangling the functional organisation of a brain region crucial for memory and learning helps reveal how individual differences are linked to variations in recall ability, aging and dopamine receptor distribution.
