Expression and potential immune involvement of cuproptosis in kidney renal clear cell carcinoma.

Cuproptosis is a newly identified programmed cell death pathway mediated by intracellular free copper. Cuproptosis genes were studied in this study for a better insight into the role of cuproptosis in cancers. The analysis identified kidney renal clear cell carcinoma (KIRC) as a cancer type most likely to be affected by cuproptosis. This study analyzed the multi-omic data to explore the cancer-noncancer expression pattern and potential immune involvement of the cuproptosis pathway in KIRC. This study clustered the TCGA KIRC samples based on the gene set of 12 cuproptosis genes to study the role of cuproptosis in the KIRC immune microenvironment and found the potential value of cuproptosis signature for immunotherapy prognosis. This study concluded that cuproptosis might affect KIRC and had potential application value in immune therapy. Hopefully, this study can contribute to the application of cuproptosis in the clinical therapy of KIRC.
