The Redox Activity of Protein Disulphide Isomerase Functions in Non‐Homologous End‐Joining Repair to Prevent DNA Damage

open access: yesAging Cell, EarlyView.
Schematic diagram illustrating the protective role of protein disulphide isomerase (PDI) against DNA damage via non‐homologous end‐joining (NHEJ), which repairs double stranded DNA breaks (DSBs). Induction of DNA damage results in the formation of γH2AX and p53‐binding protein 1 foci during NHEJ repair of DSBs.

A Comprehensive Multiomics Signature of Doxorubicin‐Induced Cellular Senescence in the Postmenopausal Human Ovary

open access: yesAging Cell, EarlyView.
Explants of human postmenopausal ovarian cortex and medulla were treated with doxorubicin for 24 h followed by culture for up to 10 days in doxorubicin‐free medium. Single nuclei sequencing and proteomics revealed an unbiased signature of ovarian senescence driven by epithelial cells in the cortex and stromal cells in the cortex and medulla ...

Identification of Functional Cellular Markers Related to Human Health, Frailty and Chronological Age

open access: yesAging Cell, EarlyView.
Human skin fibroblasts in vitro preserve the memory of age and health. ABSTRACT Aging leads to a decline in physiological reserves, an increase in age‐related diseases, reduced functional ability and a shortened healthspan. While molecular markers of chronological aging exist, their link to general health and intrinsic capacity (IC), a composite ...

Mouse genome engineering uncovers 18 genes dispensable for male reproduction

open access: yesAndrology, EarlyView.
Abstract Background Male infertility is an intricate multifactorial disease involving the interplay between genetic and environmental factors. Genetic anomalies account for more than 15% of all male infertility cases; however, diagnosing them exhibits enormous challenges due to variable symptomatic presentations and limited knowledge of gene functions.
