Silencing of CD44 Expression in Prostate Cancer by Hypermethylation of the CD44 Promoter Region

Nicole S Verkaik, Gert J van Steenbrugge, Wytske M van Weerden, Marion J Bussemakers, Theodorus H van der Kwast
2000 Laboratory Investigation  
Similarly, in 6 out of 12 in vivo-growing human prostate carcinoma xenograft models, hypermethylation of the CD44 gene was found.  ...  In the xenografts lacking hypermethylation of the CD44 gene, high levels of CD44 mRNA and protein were expressed in some models, whereas in others CD44 mRNA expression was only detectable by RT-PCR and  ...  Instead of a direct effect, it is likely that CD44 expression is suppressed by the indirect effect of the chromatin structure changes mediated by binding of MeCPs close to the Sp1.  ...
