TranscriptomicsAberrant ERK signaling causes resistance to EGFR kinase inhibitors
The clinical efficacy of EGFR kinase inhibitors is limited by the development of drug resistance. The irreversible EGFR kinase inhibitor WZ4002 is effective against the most common mechanism of drug resistance mediated by the EGFR T790M mutation. Here we show that in multiple complementary models ha...

TranscriptomicsThe role of Raf-1 kinase inhibitor protein in the regulation of pancreatic beta cell proliferation in mice
AIMS/HYPOTHESIS: Manoeuvres aimed at increasing beta cell mass have been proposed as regenerative medicine strategies for diabetes treatment. Raf-1 kinase inhibitor protein 1 (RKIP1) is a common regulatory node of the mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) pathways and...

TranscriptomicsDepletion of Erk1 and Erk2 MAP kinases in primary human keratinocytes
We assessed the effect of RNAi-mediated MAP kinase cascade signaling blockade in primary human keratinocytes. Two sets of siRNA targeting different regions of the Erk1/2 genes were used, enabling identification of off-target siRNA effects. Primary human keratinocytes were electroporated with scra...

TranscriptomicsTranscription profiling of preimplantation mouse embryos to study the requirement of the MAP kinase signaling pathway for preimplantation development.
We examined expression profiles of genes that could be regulated by the MAPK pathways during mouse preimplantation development. We used Affymetrix GeneChips for microarray analysis, and three independent experiments were carried out. 8-cell stage embryos were treated or untreated with MAPK inhibit...

ProteomicsProteomics-based insights into mitogen-activated protein kinase inhibitor resistance of cerebral melanoma metastases
Background MAP kinase inhibitor (MAPKi) therapy for BRAF mutated melanoma is characterized by high response rates but also development of drug resistance within a median progression-free survival (PFS) of 9 to 12 months. Understanding mechanisms of resistance and identifying effective therapeutic al...

TranscriptomicsFGFR signature
Drugs that target specific gene alterations have proven beneficial in the treatment of cancer. Because cancer cells have multiple resistance mechanisms, it is important to understand the downstream pathways of the target genes and monitor the pharmacodynamic markers associated with therapeutic effic...

ProteomicsChemical phosphoproteomics reveals kinase network topologies associated to genotypes and phenotypes of cancer cells.
We compare the in vitro specificity profiles of several kinase inhibitors with their effects on cellular phosphoproteomes. For this aim, we developed an algorithm which utilizes information on kinase inhibitor selectivity to determine the most probable kinase(s) acting upstream of phosphorylation si...

TranscriptomicsTranscriptional response to stress in serum deprived mouse fibroblasts in the presence of MSK1/2 inhibitor.
We have employed gene expression profiling in order to identify targets of transcriptional response to stress in resting mouse Swiss 3T3 fibroblasts, either untreated (control) or treated with anisomycin for 3 or 6 hours to induce the p38/MAP kinase pathway. In order determine transcriptional effec...

ProteomicsKinase-catalyzed Biotinylation to Map Cell Signaling Pathways (K-BMAPS): Application to Epidermal Growth Factor Signaling
Cell signaling involves a network of protein-protein interactions and post-translational modifications that govern cellular responses to environmental cues. To understand and ultimately modulate these signaling pathways to confront disease, the complex web of proteins that becomes phosphorylated aft...

TranscriptomicsTranscription profiling of mouse NIH3T3 cell line cultured with and withput FGF and treated with the MEK Inhibitor U0126 at 3 time points before FGF addition reveals ERK-dependent downregulated genes have the ability to block S phase entry
The ERK family of MAP kinase plays a critical role in growth factor-stimulated cell cycle progression from G0/G1 to S phase. But, how sustained activation of ERK promotes G1 progression has remained unclear. Here, our systematic analysis on the temporal program of ERK-dependent gene expression shows...
