circRNA_15430 knockdown promoted xenograft tumour growth in vivo. A MGC-803 cells knockdown circRNA_15430 and NC group were used to obtain the tumours of the xenograft mouse model and image. B BGC-823 cells which overexpressed circRNA_15430 and Vector group to analyzed the effect on the subcutaneous tumor in nude mice. C qRT-PCR detected the level of circRNA_15430 expression in NC and si-circRNA_15430 group subcutaneous tumor tissues. D Tumor weight of NC and si-circRNA_15430 group subcutaneous tumor. E qRT-PCR detected the expression level of circRNA_15430 in Vector and OE-circRNA_15430 group in BGC-823 cells in subcutaneous tumor tissues. F Tumor weight of Vector and OE-circRNA_15430 group subcutaneous tumor. G and H The tumor volume of each group were analyzed. *P < 0.05, **P < 0.01, ***P < 0.001
