Signal transduction and the tumor microenvironment


Our group/department has:

  • demonstrated that high constitutive hypoxia-inducible factor-1alpha (Hif-1alpha) expression in MM cells is associated with oncogenic c-Myc; anti-MM agents that decrease Hif-1alpha and c-Myc levels include bortezomib, lenalidomide, enzastaurin and adaphostin; a c-Myc/Hif-1alpha-dependent pathway mediates vascular endothelial growth factor production and secretion; and there exists a significant link between HIF1A overexpression and poor prognosis. These findings demonstrate the potential therapeutic benefit of targeting angiogenesis via a c-Myc/Hif-1alpha-dependent pathway in MM (Cancer Res 2009, 69:5082-90).
  • demonstrated a novel role for beta-catenin in ER stress and apoptotic signaling (Blood 2009, 113:1513-21).
  • demonstrated a pivotal role for Mcl-1 in bortezomib-induced apoptosis (Oncogene 2008, 27:721-31; Cancer Lett. 2014 Feb 28;343(2):286-94).
  • shown that upregulation of c-Jun inhibits proliferation and induces apoptosis via caspase-triggered c-Abl cleavage in human multiple myeloma (Cancer Res 2008, 67:1680-8).
  • demonstrated the potential therapeutic value of targeting PKC with the novel, orally available small-molecule inhibitor enzastaurin (Blood 2007, 109:1669-77).
  • demonstrated that the small-molecule VEGF receptor inhibitor pazopanib (GW786034B) targets both tumor and endothelial cells in MM (Proc Natl Acad Sci USA 2006, 103:19478-83).
