According to the KEGG pathway enrichment analysis and PPI analysis, we further found the relationship between BVES-AS1-201-50aa and the Src/mTOR signaling pathway, which is a key pathway in cancer biology and actively participates in the pathogenesis of multiple cancers, such as melanoma, hepatocellular carcinoma and non-small cell lung cancer [27, 28, 39]. Here, POPDC1 is linked to hepatocellular carcinoma.
