A time-gated model is proposed to reconcile the transient vs. persistent biological activities of cellular senescence, in which 'time' seems to be the main orchestrator of the beneficial vs. detrimental effects of the senescent programme.

Tissue damage induces a reversible cell cycle arrest in G2, which promotes survival and mitogenic signals to facilitate tissue regeneration but drives senescence-like phenotypes under chronic stress conditions.
Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.
Targeted therapies induce an aberrant fucosylation of complex tumor secretomes stimulating the expansion of minority drug-resistant clones and promoting therapy resistance.

A neural precursor cell defect precedes widespread inflammation, amyloid plaque pathology, and cognitive deficit in Alzheimer's disease, which can be reversed by inhibiting USP16.

Breast luminal epithelial cells are the hotspots of aging-associated changes, which prime aged epithelia for oncogenic gene activation and may explain individual differences in breast cancer susceptibility due to the aging-associated increase in gene expression variances in luminal epithelia.
Disruption of the intracellular vimentin network upon cellular stress results in enhanced cell surface vimentin on human osteoarthritic chondrocytes and might represent a novel membrane-associated marker of stress-induced premature senescence.
Depleting senescent osteoclasts using the senolytic drug Navitoclax (ABT263) can reduce sensory innervation in the endplate and attenuate low back pain, thus representing a potent therapy for treating spinal pain.
