Some researchers have revealed that propofol restrained cell malignant phenotypes via downregulating FOXM1 through regulating the circ_RHOT1/miR-326 axis in NSCLC [19] and the circ_TADA2A/miR-155-3p axis [12] or circ_ERBB2/miR-7-5p axis [13] in lung cancer. The gene discussed is ERBB2; the disease is lung carcinoma.
