WRAP53 and squamous cell carcinoma: Specifically, germline mutations in WDR79 that affect the WD-repeat domain result in congenital dyskeratosis,9 and WDR79 overexpression has been observed in rectal cancer,10 head and neck carcinomas,11 squamous cell carcinoma,12 breast cancer13 and ovarian cancer.14 In a previous study, we also found that WDR79 is frequently overexpressed in cell lines and tissues derived from non-small cell lung cancer (NSCLC) and accelerates NSCLC cell proliferation.15 However, the detailed mechanism underlying the effect of WDR79 on the proliferation of NSCLC cells remains unclear.
