The effects of a synthetic phenolic antioxidant, 1-O-hexyl-2,3,5-trimethylhydroquinone (HTHQ), two novel synthetic ascorbic acid derivatives, 3-O-ethyl ascorbic acid (EAsA) and 3-O-dodecylcarbomethylascorbic acid (DAsA), and phenylethyl isothiocyanate (PEITC) on 7,12-dimethylbenz[a]anthracene
Pancreatic ductal adenocarcinoma (PDAC) frequently develops therapeutic resistances, which can be divided into extrinsic and intrinsic resistance. The extrinsic resistance that arises from the surrounding dense tumor stroma is much better understood. However, the mechanisms of intrinsic resistance
OBJECTIVE
Hydrogen sulfide (H(2)S) is a prominent gaseous constituent of the gastrointestinal (GI) tract with known cytotoxic properties. Endogenous concentrations of H(2)S are reported to range between 0.2-3.4 mmol/L in the GI tract of mice and humans. Considering such high levels we speculate
Early effects (only 1 h of exposure) of three isothiocyanates (benzyl, phenylethyl, and sulforaphane) on nuclear accumulation of thioredoxin, APE/Ref-1, and transcription factors NF-kappaB and Nrf2, as well as production of reactive oxygen species (ROS) and reduced glutathione levels were examined
