Interestingly, while increased FasL expression levels were observed in L-SIL and H-SIL cases with respect to the NCL group (2.8 RUE, P=0.008, and 8.1 RUE, P = 000001), they were substantially decreased in CC cases (1.35 RUE, P=0.00001). The gene discussed is FASLG; the disease is squamous cell intraepithelial neoplasia.
