Lifespan of Mice Extended by as much as 35%; No Adverse Effects found

Clearance of senescent cells prolongs healthspan.

Clearance of senescent cells prolongs healthspan

Researchers have shown senescent cells – cells that no longer divide and accumulate with age – negatively impact health and shorten lifespan by as much as 35% in normal mice. The results demonstrate that clearance of senescent cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects.

“Cellular senescence is a biological mechanism that functions as an ’emergency brake’ used by damaged cells to stop dividing,” says Jan van Deursen, Ph.D., Chair of Biochemistry and Molecular biology at Mayo Clinic...

Tom1 Modulates Binding of Tollip to Phosphatidylinositol 3-Phosphate via a Coupled Folding and Binding Mechanism

Tom1 Modulates Binding of Tollip to Phosphatidylinositol 3-Phosphate via a Coupled Folding and Binding Mechanism •Tollip TBD is a disordered domain that partially folds when bound to Tom1 GAT •Tom1 GAT also directly binds to the Tollip C2 domain •Binding of Tom1 to Tollip inhibits binding of Tollip to PtdIns(3)P •Tollip TBD plays a major role in Tom1’s inhibitory function

It has important implications for Rx of allergies, heart disease, cancer types. The discovery explains how 2 particular proteins, Tollip and Tom1, work together to contribute to the turnover of cell-surface receptor proteins that trigger inflammation...
