Abstract

Long noncoding RNAs (lncRNAs) are considered as regulators of gene expression in cancers. However, Cancer profiling has little focused on noncoding genes. Here, we reported that RP11-115N4.1 (here renamed novel lncRNA inhibiting proliferation and metastasis [NLIPMT]) was downregulated in breast Cancer tissues. Ectopic expression of NLIPMT inhibited mammary cell proliferation, motility in vitro. Moreover, lnc-NLIPMT reduced the growth of implanted MDA-MB-231 cells in vivo. Mechanistically, glycogen synthase kinase 3β (GSK3β) was identified as an effector protein regulated by lnc-NLIPMT. Inhibition of GSK3β activity restored NLIPMT-induced inhibition of proliferation and motility in breast Cancer cells. These data reveal that lnc-NLIPMT functions as a driver of breast Cancer progression and might serve as a potential target for antimetastatic therapies.
