The imitation switch (ISWI) nuclear ATPase SMARCA5 (Snf2h) is one of the most conserved chromatin remodeling factors which are associated with various developmental disorders and cancer.21, 22 A study reported that SMARCA5 expression was higher in gastric cancer samples than in normal mucosa24 and overexpression of SMARCA5 correlated with cell proliferation and migration in breast cancer.25 In the present study, SMARCA5 expression was inversely correlated with miR‐660‐5p expression. The gene discussed is SMARCA5; the disease is breast cancer.
