In addition, mouse HL‑1 cells were cultured in a hypoxic and serum‑free medium, followed by reoxygenation to establish an <i>in vitro</i> cell model of hypoxia/reoxygenation (H/R).

RGS12 was highly expressed in both the myocardial tissues of mice with MIRI and HL‑1 cells subjected to H/R. The results from the <i>in vitro</i> experiments demonstrated that the knockdown of RGS12 reduced oxidative stress under a pathological environment, as indicated by decreased reactive oxygen species (ROS) levels and malondialdehyde activity and increased activities of superoxide dismutase and catalase. Furthermore, mice with MIRI and HL‑1 cells that underwent H/R stimulation exhibited increased ferroptosis, whereas RGS12 knockdown reversed these changes. These results showed that post‑RGS12 silencing the levels of Fe<sup>2+</sup> and lipid ROS were decreased, the expression levels of glutathione peroxidase 4 and cystine transporter solute carrier family 7 member 11 were increased and mitochondrial structure was improved by preventing the loss of the mitochondrial crest.
