Remodeling and spacing factor 1 (RSF1), which is one of chromatin‐remodeling factors, has been demonstrated to be highly expressed and associated with poor prognosis in NSCLC, renal cancer, and ovarian cancer (Wu et al., 2017; Yang et al., 2014; Zhang et al., 2018). The gene discussed is RSF1; the disease is non-small cell lung carcinoma.
