LASP1 and cancer: In contrast with the si-hsa_circ_0004370 and miR-1294 inhibitor groups, cotransfection of the two molecules obviously attenuated the changes in the mRNA level of LASP1 in both cancer cells (Figure 4I,J), confirming that hsa_circ_0004370 positively regulating LASP1 through down-regulating miR-1294.
