MHENCR and melanoma: Remarkably, CTD-3184A7.4, also termed as MHENCR, and RP11-108L7.15 have been reported to promote melanoma progression via PI3K-Akt signaling (Chen et al., 2017), and cell proliferation, migration and invasion in glioblastoma (Shi et al., 2017), further suggesting that these lncRNAs might play functional roles in COAD progression.
