In nasopharyngeal carcinoma NPC tumorigenesis, ''PCAT7'' acts as a key regulator through regulating miR-134-5p/ELF2 signal pathway. It mediates its oncogenic role by functioning as a competitive endogenous RNA (ceRNA) for miR-134-5p and directly interacts with miR-134-5p at recognized sites. ''PCAT7'' accelerates NPC cell growth partially by spongeing miR-134-5p, releasing the miR-134-5p's inhibitory role for its target gene ELF2 therefore up-regulating ELF2 and subsequently initiating ELF2 signaling pathway. <ref name="ref2"/>

''PCAT7'' is higher expressed in NPC tissues than corresponding noncancerous tissues, and higher ''PCAT7'' expression is associated with worse survival in NPC patients.

PCAT7 is a 1937-bp long non coding RNA gene located at chromosome 9q22.32. Studies suggest that PCAT7 might be acted as oncogene, a potential diagnostic marker, and a novel therapeutic target for cancer. [2]

Function

In nasopharyngeal carcinoma NPC tumorigenesis, PCAT7 acts as a key regulator through regulating miR-134-5p/ELF2 signal pathway. It mediates its oncogenic role by functioning as a competitive endogenous RNA (ceRNA) for miR-134-5p and directly interacts with miR-134-5p at recognized sites. PCAT7 accelerates NPC cell growth partially by spongeing miR-134-5p, releasing the miR-134-5p's inhibitory role for its target gene ELF2 therefore up-regulating ELF2 and subsequently initiating ELF2 signaling pathway. [2]

Expression

PCAN-R2 or PCAT7 is upregulated in metastatic prostate cancer and knockdown of this lncRNA resulted in substantial decrease in both cell growth and soft-agar colony formation in the androgen-dependent prostate cancer cell line LNCaP. [1]

PCAT7 is higher expressed in NPC tissues than corresponding noncancerous tissues, and higher PCAT7 expression is associated with worse survival in NPC patients. Silencing PCAT7 exerted tumor-suppressive roles by suppressing NPC cell proliferation in vitro and tumor growth in vivo. [2]

PCAT7 was found to be overexpressed in Non-Small-Cell Lung Cancer (NSCLC) tissues (compared with corresponding non-tumor tissues) and NSCLC cells (compared with normal cell line 16-HBE). Overexpression of PCAT7 resulted in the promotion of tumor cell proliferation, inhibition of cells apoptosis, facilitation of cells metastasis, and formation of EMT (epithelial-to-mesenchymal transition) phenotype, while PCAT7 expression deletion remarkably prohibited cell proliferation, accelerated their apoptosis, weakened metastasis, and reversed EMT to MET.
