WebTo investigate the mechanism behind the accumulation of miR-593-5p following MPP + exposure, we examined the levels of its precursor forms, pri-miR-593 and pre-miR-593, using qRT-PCR. Our results indicated that MPP + exposure did not increase the levels of these precursor forms, while miR-593-5p levels did increase ( Fig. 4 A).
