TGFB1 and Alzheimer disease: A postmortem study that included patients with Alzheimer’s disease (AD), stated that miR-30e was up-regulated in the hippocampus at Braak stages III/IV of non-demented and early AD subjects and that overexpression of the molecule increased the levels of superoxide dismutase, glutathione, and glutathione-peroxidase, and decreases ROS levels by inhibiting TGF-β [74].
