Targeting p21Cip1 highly expressing cells in adipose tissue alleviates insulin resistance in obesity

Lichao Wang et al.

Summary: This study identifies a small population of p21 high-expressing cells that accumulate in adipose tissue with obesity and shows that intermittent clearance of these cells can prevent and alleviate insulin resistance. Inactivation of the NF-kB pathway within these cells attenuates insulin resistance. Additionally, a drug combination of dasatinib and quercetin can eliminate p21 high-expressing cells in human fat and mitigate insulin resistance.

Cellular senescence in ageing: from mechanisms to therapeutic opportunities

Raffaella Di Micco et al.

Summary: Cellular senescence is characterized by permanent proliferation arrest and can occur in response to various stresses like telomere dysfunction. Apart from stress-induced senescence, it can also be part of controlled programs in biological processes like embryonic development. Senescent cells contribute to impaired tissue regeneration, chronic diseases, and organismal aging, but also present an opportunity for intervention in aging and associated diseases.
