NAD+‒circadian rhythm coupling in dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

MicroRNA‐Mediated Regulation of Brain Aging Hallmarks: Implications for Neurodegeneration and Neural Recovery

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
Hallmarks of brain aging regulated by microRNAs (miRNAs). This graphical abstract illustrates the central role of miRNAs in coordinating key biological processes associated with brain aging. miRNAs regulate multiple interconnected hallmarks, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis and impaired ...

Germline Pathogenic Variants in HER2‐Positive Breast Cancer: Spectrum and Clinical Implications in a High‐Risk Chinese Cohort

open access: yesCancer Medicine, Volume 15, Issue 5, May 2026.
ABSTRACT Objective Hereditary cancer risk assessment has predominantly focused on HER2‐negative breast cancer (BC), with limited characterization of germline pathogenic variants (GPVs) in HER2‐positive disease. This study aimed to delineate the prevalence, clinicopathological correlates, and clinical implications of GPVs in a cohort of HER2‐positive BC
