abstract：:Aging is associated not only with oxidant stress, but also with increased interleukin-6 (IL-6) levels. To determine if oxidative stress could contribute to the age-associated increase IL-6 expression, we exposed LNCaP prostate carcinoma cells and HeLa cervical carcinoma cells to H2O2 as an oxidant challenge. We found ...
