LINC00630 promotes cholangiocarcinoma cell proliferation, migration and invasion by mediating the miR-199a/FGF7 axis.

ABSTRACT: Cholangiocarcinoma (CCA) is a type of cancer with a relatively low morbidity, but poor prognosis. Aberrant long non-coding RNA (lncRNA) expression has been observed in the pathological development of CCA. In the present study, lncRNA long intergenic non-protein coding RNA 630 (LINC00630) was found to be significantly upregulated in CCA tissues and cultured cells. LINC00630 expression was positively associated with histological differentiation, TNM stage and lymph node invasion. Short hairpin RNA (sh)-LINC00630 transfection could effectively decrease CCA cell proliferation, migration and invasion. Further investigations found that LINC00630 could interact with microRNA (miR)-199a, which specifically targeted fibroblast growth factor 7 (FGF7) for degradation. FGF7 overexpression restored the
