The Role of Senescence in Crafting Cancer-Friendly Microenvironments

Posted by in categories: biotech/medical, life extension

The incidence of cancer increases exponentially as we age. Unlike most age-related diseases, which generally cause cell and tissue degeneration and loss of function, cancer cells must acquire different, albeit aberrant, functions to progress to lethal disease. One link between age-related cancer and degeneration could be an inflammatory tissue environment driven by MTOR in senescent cells.

In her groundbreaking 2010 research perspective paper, The Senescence-Associated Secretory Phenotype: The Dark Side of Tumor Suppression, Dr. Judith Campisi from the Buck Institute for Research on Aging highlighted the tumor-promoting aspects of senescent cells. Campisi’s research showcased the significant ability of senescent cells to reshape the cellular landscape around them, crafting what scientists term the ‘microenvironment.’

Far from being an inert backdrop, this microenvironment serves as a dynamic stage upon which cells interact and potentially pave the way for disease progression, particularly cancer.
