With age, senescent cells become detrimental to tissues. Mayo Clinic scientists have observed this phenomenon in the lung alveoli, where senescent macrophages accumulated in aging tissue and in early stages of non-small-cell lung cancer (NSCLC) driven by the Kras oncogene. “We found that the macrophages were present in the earliest stages of the disease. Strategies targeting these cells for elimination or preventing their accumulation would be worthwhile to test in other conditions (assuming we find they occur),” Darren Baker, a Mayo Clinic senescent cell biologist and senior author of the study, told BioWorld.
A study of more than a thousand tumor samples, led by the Weizmann Institute of Science in Israel, gives valuable insight into the different gene expression patterns seen in different cancers. The new findings could help address challenges associated with targeting many types of tumors, which are hard to treat in large part due to the variable nature of their cells and gene expression patterns, by helping to create better targeted therapeutics.
