also reported that ferroptosis was associated with DN, that ferroptosis-related molecules, such as SlC7A11 and GPX4, were reduced in kidney biopsy samples from patients with DN compared with those from non-DN patients, and that the mRNA and protein expression of SLC7A11 and GPX4 were reduced in the kidneys of DM mice compared with that in control mice (16).Wang et al. The gene discussed is GPX4; the disease is diabetes mellitus.
