The present invention relates to the mitogen-activated protein kinase called MAPK5. The rice MAPK5 gene, its protein and kinase activity were induced by abscisic acid, pathogen infection, wounding, drought, salt and cold temperature. However, suppression of MAPK5 expression and kinase activity in dsRNAi transgenic plants resulted in constitutive expression of pathogenesis-related genes such as PR-1 and PR-10 but enhanced resistance to fungal and bacterial pathogens. In contrast, overexpressed transgenic lines exhibited elevated MAPK5 kinase activity and increased tolerance to drought, salt and cold stresses. This invention provides methods for increasing tolerance to abiotic and biotic stress in plant using MAPK5.

The invention provides novel means to inhibit the Mitogen Activated Protein Kinases (MAPKs) pathway activated by Ras/Raf complex using GILZ protein related compounds as inhibitors of Raf/Ras-mediated signal transduction. Pharmaceutical compositions containing such compounds are also disclosed.

The present invention provides for methods and compositions for treating cancer. A subject having cancer is administered an interferon and an inhibitor of mitogen-activated protein kinase (MAPK) signaling pathway. The combination of the interferon and the inhibitor of the MAPK pathway produces a synergistic effect on the cancer compared to the effect of the interferon or the inhibitor of the MAPK pathway alone. The activity of the interferon pathway, interferon expression levels and/or interferon locus copy number can be used as biomarkers for treatment of cancer by MAPK pathway inhibitors.
