Recently,a pathway enrichment analysis revealed that the OCIAD2 coexpressedgenes derived from RNA-seq data sets are enriched in mitochondria-relatedsignaling pathways. Given the modestcorrelation between RNA levels and expression of protein products,, transcriptome-level analyses may not be sufficient to fully understandthe role of OCIAD2 in lung adenocarcinoma. Here, OCIAD2 is linked to lung adenocarcinoma.
