摘要
In the present study, we aimed to examine whether SET domain-containing methyltransferases are up-regulated in different classes of renal cell carcinoma. We immunoblotted against SET domain and quantified the expression of these modular domains. Furthermore, we examined the expression of Rad51, the key protein that confers genomic stability. There was enhanced expression of SET domain-containing histone methyltransferases in whole lysates of all classes of renal carcinoma. In metastatic high grade clear cell carcinoma, this expression was more pronounced. Though we could not demonstrate direct correlation, we showed that epigenetic modification by methylation is associated with decreased genomic translation of Rad51.
