Fig. 5From: Circular RNA circ_0081001 knockdown enhances methotrexate sensitivity in osteosarcoma cells by regulating miR-494-3p/TGM2 axisThe expression of TGM2 was regulated by circ_00081001 and miR-494-3p in MTX-resistant OS cells. a, b WB assay was employed to examine the protein level of TGM2 in U2OS/R and HOS/R cells after transfection with sh-NC, sh-circ_00081001, sh-circ_00081001 + anti-miR-NC, or sh-circ_00081001 + anti-miR-494-3p. **P < 0.01Back to article page
