Study details cancer-promoting mechanisms of overlooked components in secondhand smoke

A University of Colorado Cancer Center study published in the journal PLoS One explores two of these low-molecular-weight (LMW) PAHs — 1-methylanthracene (1-MeA) and 2-methylanthracene (2-MeA) — and shows that while they don’t necessarily cause cancer, 1-MeA promotes conditions that will likely allow cancer to grow. "There’s a big distinction between initiating cancer and promoting it," says Alison Bauer, PhD, CU Cancer Center investigator and assistant professor at the Colorado School of Public Health. Her study showed that in a mouse cell model using a progenitor cell of lung cancer, the LMW 1-MeA promoted inflammation and increased mitogenic pathways, both of which are linked to tumor promotion. 2-MeA, while nearly structurally identical, did not…
