MicroRNA-24-1 suppresses mouse hepatoma cell invasion and metastasis via directly targeting O-GlcNAc transferase

0 views | Jan 14 2019

Liu Y et al. suggested that as a tumor suppressor, miR-24-1 may regulate mouse hepatocarcinoma cells migration and invasion, at least partially through targeting OGT, which could regulate the O-GlcNAcylation and the stability of this oncoprotein c-Myc. This may give insight into a novel mechanism and therapy of tumor lymphatic metastasis. [Read the Full Post]
