Furthermore, we were able to dissect distinct properties of the Rb family by demonstrating that p130/pRb2 inhibits proliferation of the glioblastoma cell line T98G, which is resistant to the growth suppressive effects of both pRb and p107.     ///    p130/pRb2 has growth suppressive properties similar to yet distinctive from those of retinoblastoma family members pRb and p107..
