Exploring the interlaced relationship between cellular senescence, cancer and aging
Why do we get more cancer as we get older and how to treat it: The role of aging cells
Just like us, individual mammalian cells get old. This cellular aging phenomenon, termed cellular senescence, is normally a good thing. Cellular aging is hardwired into a cell genetic program and is activated in response to cellular stresses or damages that could otherwise turn a normal cell into a cancer cell. In short, cellular senescence prevents the apparition of cancer cells via activation of a stable growth arrest. But that's not the only reason why senescence exists, it is also activated by stress during tissue repair, mostly because senescent cells are adept at communicating with other cells and coordinate the repair process. Unfortunately, during normal aging or diseases associated with age, senescent cells accumulate beyond a normal threshold and disorganize tissues leading to organ dysfunctions including a paradoxical increase in tumor growth. The cellular and molecular mechanisms that regulate the accumulation and the biological functions of senescent cells remains poorly understood, which provide opportunities for discovery and room for novel therapeutic interventions.
Current projets (techniques used):
My laboratory uses human, animal and cell models to understand how aging cells contribute to tissue malfunctions and we are attempting to use this knowledge to ameliorate human healthspan. For example, one of our projects tries to understand how and why rheumatoid arthritis is associated with premature aging of the immune system. More recently, we have observed that cancer treatments like radiation or chemotherapy also activate premature cellular aging, both in normal tissues and in the treated tumors. How premature cell senescence contributes to the outcome of cancer treatment remains unappreciated providing a discovery opportunity. Taking into account the good and bad sides of cellular aging (senescence), we are focusing our discovery efforts on determining which specific aspects are good or bad and whether we can optimize beneficial effects while negating detrimental effects to improve age- associated diseases or cancer treatments.
