Reference title
Long non-coding RNA PCAT7 regulates ELF2 signaling through inhibition of miR-134-5p in nasopharyngeal carcinoma.
Experimental verification
qPCR,Western blot,Luciferase reporter assay
Functional description
Relative expression of PCAT7 expression in NPC cell lines and normal oral epidermal cell.Here, we discovered the novel LncRNA, prostate cancer associated transcript 7 (PCAT7), which was overexpressed and associated with worse prognosis in NPC. Decreased PCAT7 expression was found to significantly suppress tumor cell proliferation in vitro, and inhibited tumor growth and reduced the expression of proliferation antigen Ki67 in vivo. Rescue assay was performed to further confirm that PCAT7 contributed to the progression of NPC through regulating miR-134-5p/ELF2 signal pathway.The Kaplan-Meier survival analysis indicated that PCAT7 high expression has a worse overall survival compared to the low expression subgroup hese results indicated that PCAT7 might contribute to the tumor progression in NPC by functioning as a ceRNA to sponge miR-134-5p.
