TranscriptomicsTranscription profiling of human pancreatic duct epithelial cell line (H6c7) Gene expression changes induced by K-ras oncogene in the
k-ras oncogene was transduced into the HPV16-E6E7 immortalized normal human pancreatic duct epithelial cell line (H6c7) to generate a stable K-ras oncogene-expressing cell line (H6c7-Kr). The gene expression profile of the H6c7-Kr cells was compared to that of H6c7 cells. We have excluded (subtracte...

TranscriptomicsMutant K-ras promotes carcinogen-induced murine colorectal tumourigenesis, but does not alter tumour chromosome stability
K-ras mutations are observed in around 40% human colorectal adenomas and carcinomas and contribute to the pathogenesis of human and rodent colorectal tumour formation. Previously, we developed and characterised a strain of transgenic mice with inducible intestinal epithelial expression of K-rasVal12...

TranscriptomicsDisplacement and re-accumulation of centromeric cohesin during transient pre-anaphase centromere splitting
The ring-shaped cohesin complex links sister chromatids until their timely segregation during mitosis. Cohesin is enriched at centromeres, where it provides the cohesive counter-force to bi-polar tension produced by the mitotic spindle. As a consequence of spindle tension, centromeric sequences tran...

ProteomicsIntegrative proteomic and transcriptomic profiling identifies unique and shared functions of oncogenic KRAS and RIT1
Lo A, Holmes K, Mundt F, Moorthi S, Fung I, Fereshetian S, Watson J, Carr SA, Mertins P, Berger A. Aberrant activation of RAS oncogenes is a prevalent event in lung adenocarcinoma, with somatic mutation of KRAS occurring in ~30% of tumors. Recently, we identified somatic mutation of the RAS-family G...

TranscriptomicsPten loss and RAS/MAPK activation cooperate to promote EMT and prostate cancer metastasis initiated from stem/progenitor cells
PTEN loss or PI3K/AKT signaling pathway activation correlates with human prostate cancer progression and metastasis. However, in preclinical murine models, deletion of Pten alone fails to mimic the significant metastatic burden that frequently accompanies the end stage of human disease. To identify...

TranscriptomicsCohesin localisation along fission yeast chromosomes delineates conserved mechanisms of binding
Cohesin holds sister chromatids together to enable their accurate segregation in mitosis. How, and where, cohesin binds to chromosomes are still poorly understood, and recent genome-wide surveys have revealed an apparent disparity between its chromosomal association patterns in different organisms. ...

TranscriptomicsDefective K-Ras Oncoproteins Initiate Cancer In Vivo and Evolve to Overcome Impaired Effector Binding
The oncogenic proteins expressed in human cancer cells are exceedingly difficult targets for drug discovery due to intrinsic properties of the Ras GTPase switch. As a result, recent efforts have largely focused on inhibiting Ras-regulated kinase effector cascades, particularly the Raf/MEK/ERK and PI...

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...

TranscriptomicsHeLa cell response to overexpression of wild type and mutated forms of the P19 splice variant of c-H-ras
The c-H-ras proto-oncogene undergoes alternative splicing of the exon termed IDX giving rise to a novel protein of the Ras family, p19 (H-RasIDX). The experiment tests the effect on the transcriptome of overexpressing the wild type and W164A mutated forms of p19. Keywords: genetic modification Thre...
