COXFA4L2 and nonpapillary renal cell carcinoma: Lucarelli et al. used integrative omics analysis of ccRCC involving metabolomics, genomics, and transcriptomics and identified NDUFA4L2 (NADH dehydrogenase 1 alpha subcomplex 4‐like 2) as the gene most highly expressed in ccRCC, and further they experimentally showed that this gene can functionally participate in cancer cell‐mediated angiogenesis as well as several other biological processes that affect cancer growth (Lucarelli et al., 2018).
