This study evaluated oxidative stress markers in Human Sertoli cells cultivated on Geltrex® and exposed to Monobutyl Phthalate (MBP), and the potential cytoprotective role of GIM-1 on the antioxidant response. Exposure was performed at 30 min, 1, 12 and 48 h into 4 groups: control, MBP (10μM), GIM-1 (0,05μM) and MBP + GIM-1. Morphology was evaluated. Antioxidant enzymes were analyzed by colorimetric method; NRF-2, SIRT-1, 8- OHdG and Cleaved Caspase-3 by Western Blot. Larger spaces between cells were shown in MBP treatment; GIM-1 was similar to Control and MBP + GIM-1 showed an intermediate aspect. MBP reduced enzymatic activity of all enzymes and NRF-2 expression, increasing cleaved Caspase-3 expression; while GIM-1 increased antioxidants markers alone and attenuated MPB effects in MBP + GIM-1. MBP induced deleterious effects on Sertoli cells, increasing the oxidative stress, apoptosis and modifying their distribution in culture; however, GIM-1 acted as an important cytoprotective agent reversing our attenuating MBP effects.
