Fig. 1A shows the ubiquitous expression of hFAF1 is in various cell lines. Fig. 1B shows that the expression of hFAF1 is significantly reduced in six squamous cell carcinomas and one adenocarcinoma compared to normal cervical tissues. Because it has been reported that Hsp70s, chaperones that refold denatured proteins, significantly increase in tumor tissues [18], we investigated the effect of hFAF1 expression on tumor formation. The gene discussed is FAF1; the disease is adenocarcinoma.
