In conclusion, mTORC1 signaling contributes to the ISC fate decision, enabling regional control of intestinal cell differentiation in response to nutrition. « Back to Top Reviewing the Development of Senotherapeutics to Treat Aging https://www.fightaging.org/archives/2024/02/reviewing-the-development-of-senotherapeutics-to-treat-aging/ Senescent cells accumulate with age and contribute meaningfully to chronic inflammation and degenerative aging. Destroying these cells produces rapid and sizable reversal of age-related diseases in mice, demonstrating that the presence of senescence cells acts to maintain a more dysfunctional, inflamed metabolism. This is well known by now, and numerous biotech companies in the first wave of development of senolytic treatments to selectively destroy senescent cells are in varying stages of preclinical and clinical development. Meanwhile, the off-label use of dasatinib and quercetin, a low-cost senolytic therapy that is neither developed nor promoted by any company, continues to look promising based on the slow progression of clinical trials. Cellular senescence is implicated in ageing and associated with a broad spectrum of age-related diseases. Importantly, a cell can initiate the senescence program irrespective of the organism's age. Various stress signals, including those defined as ageing hallmarks and alterations leading to cancer development, oncogene activation, or loss of cancer-suppressive f...
