RECQL and cancer: RECQL is highly expressed in various human cancer types and tumor cell lines (Mendoza-Maldonado et al, 2011; Sharma, 2014; Viziteu et al, 2017), and high expression levels are correlated with poor clinical prognosis (Li et al., 2006; Futami et al, 2010; Arai et al, 2011; Futami & Furuichi, 2014).
