Ferroptosis, an iron\u2010dependent form of regulated cell death, exacerbates the neurological damage associated with TBI. This study investigates whether nicorandil, a potassium channel opener with nitrate\u2010like properties known for its antioxidative and neuroprotective effects, can mitigate depression\u2010like behaviors following TBI by modulating ferroptosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A controlled cortical impact (CCI) device was used to establish the TBI model. Depression\u2010like behaviors in rats were assessed using the sucrose preference test (SPT), the tail suspension test (TST), and the forced swimming test (FST). The antioxidant system, lipid peroxidation, and ferroptosis levels were evaluated. The SLC7A11\/GPX4 axis was analyzed using quantitative real\u2010time PCR (qRT\u2010PCR) and Western blot analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Nicorandil administration significantly ameliorated depression\u2010like behaviors in rats with TBI. Nicorandil administration also effectively restored the antioxidant system, substantially reduced lipid peroxidation, and attenuated ferroptosis in the hippocampus of rats with TBI. Mechanistically, nicorandil administration promoted the SLC7A11\/GPX4 axis in the hippocampus of rats with TBI. Crucially, knockdown of hippocampal SLC7A11 abrogated the protective effects of nicorandil on depression\u2010like behaviors, lipid peroxidation, and ferroptosis in the hippocampus of rats with TBI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These findings indicate that
