TranscriptomicsRAS/MAPK activation drives resistance to Smo inhibition, metastasis and tumor evolution in Shh pathway-dependent tumors
Aberrant Shh signaling promotes tumor growth in diverse human cancers. The importance of Shh signaling is particularly evident in medulloblastoma and basal cell carcinoma (BCC), where inhibitors targeting the Shh pathway component Smoothened (Smo) show great therapeutic promise. However, the emergen...

TranscriptomicsExpression data from Control, AKT and RAS transduced cells
Mutations in both RAS and the PTEN/PIK3CA/AKT signaling module are found in the same human tumors. PIK3CA and AKT are downstream effectors of RAS, and the selective advantage conferred by mutation of two genes in the same pathway is unclear. Based on a comparative molecular analysis, we show that ac...

TranscriptomicsDownstream targets of let-60 Ras in Caenorhabditis elegans
In Caenorhabditis elegans, let-60 Ras controls many cellular processes, such as differentiation of vulval epithelial cells, function of chemosensory neurons, and meiotic progression in the germ line. Although much is known about the let-60 Ras signaling pathway, relatively little is understood about...

TranscriptomicsTranscription profiling of C. elegans with activated let-60 Ras
In Caenorhabditis elegans, let-60 Ras controls many cellular processes, such as differentiation of vulval epithelial cells, function of chemosensory neurons, and meiotic progression in the germ line. Although much is known about the let-60 Ras signaling pathway, relatively little is understood about...

ProteomicsLabel-free quantitative phosphoproteomics with novel pairwise abundance normalization reveals synergistic RAS and CIP2A signaling
Label-free quantification is a powerful method for studying cellular protein phosphorylation dynamics. However, whether current data normalization methods achieve sufficient accuracy has not been examined systematically. Here, we demonstrate that a large uni-directional shift in the phosphopeptide ...

TranscriptomicsSelective Requirement for Mediator MED23 in Ras-active Lung Cancer
K-RAS activating mutations occur frequently in non-small cell lung cancer (NSCLC), leading to aberrant activation of Ras-MAPK signaling pathway that contributes to the malignant phenotype. However, the development of Ras-targeted therapeutics remains challenging. Here, we show that MED23, a componen...

TranscriptomicsPrimary and ras keratinocytes plus TGFbeta1
We have compared the response to TGFbeta1 in normal and v-rasHa transduced primary mouse keratinocytes using NCI cDNA microarrays. This analysis reveals that Ha-ras alters global TGFbeta1 mediated gene expression in a gene specific manner. The expression pattern of TGFbeta1 immediate early response ...

TranscriptomicsRNA-Seq of Ras induced Epithelial to Mesenchymal Transition (EMT) in Madin-Darby Canine Kidney (MDCK) cells
To gain more information about EMT induced by oncogenic Ras in MDCK cells, we performed RNA-seq of MDCK and MDCK-Ras cells and compared their genome-wide gene expression profiles.

GenomicsOncogenic ETS proteins replace activated Ras/MAPK signaling in prostate cells.
Approximately 50% of prostate cancers have chromosomal translocations resulting in the over-expression one of four ETS family transcription factors. However, it is not known why these four four family members are selected for oncogenic roles, while other ETS proteins are not. We found that the four...
