However, considering the limitations of the experimental conditions, we did not have more opportunities to deeply explore the specific mechanisms of these genes in renal cancer-associated ferroptosis; as a result, how SLC7A11, HMOX1, and MT1G induce ferroptosis in different subtypes of renal cancer cells remains unknown; nevertheless, it will be the main direction of our subsequent studies. The gene discussed is HMOX1; the disease is renal carcinoma.
