To investigate whether URGCP regulates the expression of these regulators in glioma, we performed western blotting and found that silencing URGCP only suppressed Cyclin D1 and Cyclin E1 expression, while, URGCP overexpression enhanced Cyclin D1 and Cyclin E1 expression in U87 and U251 cells (Fig. 3a). This evidence concerns the gene CCNE1 and central nervous system cancer.
