LncRNA TRPM2-AS promotes ovarian cancer progression and cisplatin resistance by sponging miR-138-5p to release SDC3 mRNA

TRPM2-AS contributed to the OvC progression in vitro. (A) RT-qPCR analysis revealed that the TRPM2-AS was overexpressed in ovarian tumor tissues (Tumor) compared with the contralateral normal fallopian tube tissues (cNor FT) and normal fallopian tube tissues from patients with benign gynecological tumor (Nor FT). (B) RT-qPCR analysis revealed that the TRPM2-AS was overexpressed in four OvC cell lines (EB0405, CAOV3, HEY and SKOV3) compared with human ovarian surface epithelial cell line IOSE-80. (C) TRPM2-AS was mainly located in cytoplasm. (D) The high transfection efficiency of sh-TRPM2-AS and TRPM2-AS overexpression in CAOV3 and SKOV3 cells. (E) TRPM2-AS was proved to promote cell viability in CAOV3 and SKOV3 cells by CCK8 assay. (F) The colony formation ability was enhanced by TRPM2-AS. (G) TRPM2-AS promoted cell migration by the assessment of wound healing assay. (H) TRPM2-AS enhanced the cell invasive ability by Transwell invasion assay. Blank, blank control. NC, negative control.
