Downregulation and upregulation of receptors

WebWe demonstrated that miR-3928 is down-regulated in GBM tumor tissue samples and GBM cell lines and that it strongly suppresses growth and invasiveness in a panel of GBM cell lines as well as in in vivo GBM xenografts. We show that miR-3928 exogenous expression leads to the degradation of multiple important oncogenes.
