  • RAS and RAF members were initially discovered as viral oncogenes that transformed mammalian cells and such eventually lead to the identification of human homologs with similar oncogenic transforming activity (Rapp, U.R., et al., Proc. Natl. Acad. Sci., 80: 4218-4222, 1983: Malumbres, M. and Barbacid, M., Nat. Rev. Cancer, 3: 459- 465, 2003 and references therein).
  • RAF activation is normally regulated by an upstream RAS-GTP bound complex that orchestrates RAF binding to the cell membrane. Subsequent conformational changes induce RAF phosphorylation and kinase activity. The active RAF kinase then phosphorylates and activates MEK, that in-turn phosphorylates and activates ER 1/2 in a signaling cascade that is conserved across a wide variety of animal species (Kolch, W. Biochem. J. 351 : 289-305, 2000 and references therein).
  • A-RAF A-RAF
  • B-RAF B-RAF
  • C-RAF also known as c-RAF-1
  • signaling of RAF to MEK normally requires KSR, a RAF homo log lacking intrinsic kinase activity acting as a scaffold in protein-protein interactions.
  • B-RAF gain-of-function mutations identified to date involve substitution of a valine for a glutamic acid at position 600.
  • V600E this single amino acid substitution leads to constitutive kinase activity approximately 500-fold higher than basal wild-type B-RAF kinase activity (Wan, P.T.C., et al, Cell, 116: 855-867, 2004; Garnett, M.J. and Marais, R. Cancer Cell, 6: 313-319, 2004).
  • B-RAF (V600E) is by itself transforming, and increases tumor cell proliferation, survival and tumor growth in vivo (Davies, H., et al, Nature, 417: 949-954, 2002; Wellbrock, C, et al, Cancer Res., 64: 2338- 2342, 2004). Furthermore, B-RAF (V600E) mutations have been correlated with decreased response rates in cancer patients undergoing chemotherapy (Samowitz, W.S., et al, Cancer Research, 65: 6063-6069, 2005; Houben R., et al, J. Carcinogenesis, 3: 6-18, 2004).
  • siRNA directed to B-RAF (V600E) results in tumor cell growth arrest and/or apoptosis (Karasarides, M., et al, Oncogene, 23: 6292- 6298, 2004; Hingorani, S.R., et al, Cancer Res., 63: 5198-5202, 2003; Hoeflich, K.P., et al,
  • MAPK mitogen-activated protein kinase
  • cytokines pro-inflammatory cytokines
  • MAPKs mitogen-activated protein kinase family involved in the regulation of cell survival and cell stress responses, and are indeed also activated by pro-inflammatory cytokines. Inhibition of p38 MAPK activity may limit growth and/or survival of certain cancer cells expressing high basal activity of these kinases. However, in other cell types p38 MAPKs may be pro-survival signaling molecules whose inhibition then sensitizes cancer cells to apoptosis (Xia et al, Science, 270: 1326-1331, 1995; Potapova et al, J. Biol. Chem., 272: 14041-14044, 1997, and references therein). Taken together these results suggest that p38 MAPK inhibitors appropriately targeted to tumors dependent on signaling through the p38 MAPK pathway may have antitumor effects.
