Annotated Information
Name
CERNA3:competing endogenous lncRNA 3 for miR-645
CTA [1]
Function
LncRNA CTA is an essential regulator in DOX-induced (doxorubicin) osteosarcoma cell apoptosis, and the lncRNA CTA-miR-210 interaction plays an important role in reducing osteosarcoma chemoresistance [1]. Overexpression of lncRNA CTA markedly enhances DOX-induced apoptosis and inhibition of proliferation in osteosarcoma cells, MG63 and Saos-2 cells. Moreover, lncRNA CTA exerts a synergic effect with DOX in increasing the levels of Caspase 3 and in decreasing the levels of Bcl-2 and in growth inhibition of osteosarcoma cells in nude mice [1].
Low expression of lncRNA CTA is significantly associated with the advanced clinical stage, tumor size and the malignant progression of osteosarcoma, and patients with low lncRNA CTA expression show a worse prognosis when compared with those with high level of lncRNA CTA [1].
Regulation
Chronic exposure to DOX induces significant downregulation of CTA in osteosarcoma MG63/DOX cells compared with their parental cells, and bioinformatic analysis shows that lncRNA CTA is a direct target of miR-21 [1].
Expression
CTA's expression is significantly decreased in osteosarcoma tumor tissues compared with adjacent tissues [1].
Diseases
Osteosarcoma [1]
