To evaluate the role of ATG7 in MIR190A mediation of BC invasion, we stably transfected ATG7 constitutively expressed plasmid into UMUC3(Anti‐MIR190A) cells to see whether ectopic expression of ATG7 could reverse the inhibitory effect of Anti‐MIR190A on BC invasion. The gene discussed is ATG7; the disease is breast cancer.
