Alkyl esters of gallic acid inhibited the respiration rate of mouse sarcoma 786A and mouse mammary adenocarcinoma TA3 cell lines and its multiresistant variant TA3-MTX-R more effectively than gallic acid, both in the absence and in the presence of the uncoupler CCCP. The order of inhibition of the
The role of reactive oxygen (RO) in the promotion of neoplastic transformation of JB6 mouse epidermal cells by 12-O-tetradecanoylphorbol-13-acetate (TPA) was investigated using inhibitors of RO itself or RO generating systems of seven different types. Bovine erythrocyte CuZn superoxide dismutase
The anti-oxidant and the anti-tumor-promotion activities of several hydrolyzable tannins (HTs), including a commercial tannic-acid (TA) mixture, were examined in mouse skin treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) in vivo. A single application of TPA gradually increases the
We examined the relationship between natural killer (NK) cell-mediated cytotoxicity, the produced active-oxygen and cytotoxic factor (CF) release in co-culturing canine NK cells with tumor cells (CL-1 target cells). In co-culturing, the adding of n-propyl gallate (active-oxide scavenger) removed the
