From: Downregulation of CDKN2A and suppression of cyclin D1 gene expressions in malignant gliomas
Konckdown of CDKN2A promotes the low grade gliomas to high grade gliomas. Western blot analysis revealed a markedly decreased expression of CDKN2A after tranfecting a pool of four siRNA duplexes for CDKN2A in HS-683 and H4 cell lines(A). Knockdown of CDKN2A accelerates the growth of HS-683 (B) and H4 (C) glioma cell lines. However, flavopiridola, a cyclin D1 inhibitor, can reverse the accelerated cell growth both of HS-683 and H4 cell lines.
