ARHGEF2 and nonpapillary renal cell carcinoma: Notable lncRNAs of the green module (increased in SR, then decreased under regorafenib) include ARHGEF2-AS2, a survival predictor in clear cell renal cell carcinoma (ccRCC) [43], and AC007563.2, AC013451.1, LINC00607, and LINC01583, which are potentially involved in angiogenesis and cell adhesion [44–47].
