During cell proliferation, previous studies have found that both miR‐30a‐5p and Wnt/β‐catenin are mostly negatively correlated, such as the miR‐30a‐5p/chromodomain helicase DNA binding protein 1 (CHD1) axis, which, through inhibition of the Wnt/β‐catenin signaling pathway inhibits the proliferation, migration and invasion of ovarian cancer cells to achieve apoptosis [34]. The gene discussed is CHD1; the disease is ovarian cancer.
