CircAHNAK1 inhibits proliferation and metastasis of triple-negative breast cancer by modulating miR-421 and RASA1

Figure 2. Overexpression of circAHNAK1 inhibits proliferation and metastasis of TNBC. (A)Successfully established two breast cancer cell lines that overexpress circAHNAK1; (B) CCK-8 assay to evaluate the effect of circAHNAK1 on cell proliferation; (C) Colony formation assay to evaluate the effect of circAHNAK1 on cell colony forming ability; (D) Number of clones quantified by ImageJ; (E) Transwell invasion assay to evaluate the effect of circAHNAK1 on cell invasion; (F) ImageJ quantifies the number of invading cells; (G) Wound healing assay evaluates the effect of circAHNAK1 on wound closure; (H) ImageJ quantifies the extent of wound healing; (I) Xenograft model to evaluate the effect of circAHNAK1 on tumor proliferation in vivo; (J) Effect of circAHNAK1 on proliferation in vivo by tumor weight; (K) Representative images of luciferase signaling to assess the effects of circAHNAK1 on lung metastasis in vivo; (L) Representative images of HE staining of lung metastatic nodule sections; (M) Quantification of the number of lung metastatic nodules.
