SOD2 and gastric cancer: Of interest, the interaction between WDR5 and GClnc1, a long non-coding RNA (lncRNA), ensures its recruitment to a subset of pro-metastasis genes to activate transcription in gastric cancer cells[36], suggesting that non-protein factors could also contribute to the tethering of WDR5 to selective promoters although it is not clear whether these processes are independent of each other or act in concert.
