SOX11 promotes tumor angiogenesis through transcriptional regulation of PDGFA in mantle cell lymphoma.
Published: October, 2014

Abstract: SOX11 is overexpressed in several solid tumors and in the vast majority of aggressive mantle cell lymphomas (MCLs). We have recently proven that SOX11 silencing reduces tumor growth in a MCL xenograft model, consistent with the indolent clinical c...
