Similarly, cryptotanshinone (CTS), a bioactive component of Salvia miltiorrhiza, was shown to sensitize gefitinib‐resistant EGFR‐mutant lung cancer cells by targeting catalase (CAT), heme oxygenase 1 (HMOX1) and stearoyl‐CoA desaturase (SCD). The gene discussed is SCD; the disease is lung carcinoma.
