MTMR3 is a direct target of miR-99a-5p. a Potential binding site of miR-99a-5p for MTMR3 as predicted by TargetScan. b Luciferase reporter assay for determining whether miR-99a-5p could bind to wt-MTMR3–3’UTR or mut-MTMR3–3’UTR. c Pull-down assay confirmation of MTMR3 as a target of miR-99a-5p. d RIP assay confirmation of the interaction between miR-99a-5p and MTMR3. e qRT-PCR analysis revealing that downregulation of miR-99a-5p could increase the expression levels of MTMR3. f Increased protein expression levels of MTMR3 after knockdown of miR-99a-5p. g qRT-PCR analysis of the expression of MTMR3 CDDP-sensitive and CDDP-resistant GC cells. h MTMR3 detection in CDDP-resistant and CDDP-sensitive GC cells by western blotting. i MTMR3 expression detection using qRT-PCR in CDDP-sensitive and CDDP-resistant GC tissues. j Negative correlation between MTMR3 expression and miR-99a-5p expression. k and l qRT-PCR analysis showing that MTMR3 expression was increased by circMCTP2 but reversed by overexpression of miR-99a-5p. m and n Diminishment of the promotive effect of circMCTP2 on the protein expression of MTMR3 by the overexpression of miR-99a-5p.
