TranscriptomicsKRAS-Dependent Sorting of miRNAs and other small RNAs to secreted vesicles
Although long thought to act cell autonomously, mutant KRAS colorectal cancer (CRC) cells release protein-laden exosomes that can alter the tumor microenvironment. We have previously shown that mutant KRAS induces EGFR-ligand trafficking to exosomes and drastically alters exosomal protein contents,...

TranscriptomicsRescue of KRAS suppression in HCT116 colon cancer cell line
Cancer cells that express oncogenic alleles of RAS typically require sustained expression of the mutant allele for survival, but the molecular basis of this oncogene dependency remains incompletely understood. To identify genes that can functionally substitute for oncogenic RAS, we systematically ex...

TranscriptomicsGene expression profiling by DNA microarray in Colo741 cell line transfected by KRas-G12D or KRas-G12V
Mutations of the proto-oncogene KRas, together with the inactivation of the onco-suppressor genes APC and TP53, are considered to have an important role both in the carcinogenesis and in the colorectal tumor progression. The oncogene K-ras has activating mutations, especially in codon 12, in about ...

TranscriptomicsKRAS and YAP1 converge to regulate EMT and tumor survival
Cancer cells that express oncogenic alleles of RAS typically require sustained expression of the mutant allele for survival, but the molecular basis of this oncogene dependency remains incompletely understood. To identify genes that can functionally substitute for oncogenic RAS, we systematically ex...

TranscriptomicsKras mutant v WT with or without AZD6244 in vivo study
HCT116 (kRas mt) cells and HKH2 (Kras wt) cells were implanted into the right and left flanks of nude mice and either untreated or treated with a MEK inhibitor (AZD6244) over time. Tumours were excised and harvested for RNA extraction at the end of the experiment and hybridised to the Colorectal DS...

GenomicsEffect of a KRAS peptide nucleic acid clamp on the Ion Torrent sequencing protocol
To test whether the addition of a peptide nucleic acid (PNA) clamp, which binds WT KRAS at codon 12, can increase the efficacy of mutation detection for KRASG12D within a targeted NGS setting. We tested the effect of clamping the wild-type KRAS sequence in a reference standard (Tru-Q 7, 1.3% Tier fr...

ProteomicsDynamic conformational equilibria in the active states of KRas and NRas
The design of potent RAS inhibitors benefits from a molecular understanding of the dynamics in KRAS and NRAS and their oncogenic mutants. Here we characterize switch-1 dynamics in GTP-state KRAS and NRAS by 31P NMR, by 15N relaxation dispersion NMR, hydrogen-deuterium exchange mass spectrometry (HDX...

TranscriptomicsExpression profiling of KRas ablation surviving cells and matched Kras expressing spheres in pancreatic tumors
In this dataset, we include the expression data obtained from KRas expressing tumors, matched Kras expressing tumor spheres, surviving cells and surviving cells after KRas re-expression for 24hs Data reported here are obtained from 5 independent tumors (from 1 to 5). For each tumor, expression data ...
