Expression data comparing KRas(G12D/+);CreT, R26(H1047R/+);KRas(G12D/+);CreT, and MMTV-Neu mouse mammary tumors

Project description:Breast Cancer (BC) has been associated with alterations in signaling through a number of growth factor and hormone regulated pathways. Mouse models for metastatic BC have been developed using oncoproteins that activate PI3K, Stat3 and Ras signaling. To determine the role of each pathway, we analyzed mouse mammary tumor formation when they were activated singly or pairwise. We used microarrays to detect differentially expressed genes in the KRas(G12D/+);CreT and R26(H1047R/+);KRas(G12D/+);CreT tumors Total RNA was extracted from tumors developed by Qiagen RNAeasy kit and hybridized on Affymetrix microarrays.

Disruption of STAT3 signaling promotes KRAS induced lung tumorigenesis

Project description:Oncogenic STAT3 functions are known in various malignancies. We found that STAT3 plays an unexpected tumor suppressive role in KRAS-mutant non-small-cell-lung cancer (NSCLC). In mice, tissue-specific inactivation of Stat3 resulted in increased Kras (G12D)-driven NSCLC initiation and malignant progression leading to markedly reduced survival. Clinically, low STAT3 expression levels correlate with poor survival in human lung adenocarcinoma patients with smoking history. Consistently, KRAS-mutant lung tumors showed reduced STAT3 levels. Mechanistically, we show that STAT3 controls NFÎºB-induced IL-8-expression by sequestering NFÎºB in the cytoplasm while IL-8 in turn regulates myeloid tumor infiltration and tumor vascularization thereby promoting tumor progression. These results identify a novel STAT3-NFÎºB-IL-8 axis in KRAS-mutant NSCLC with therapeutic and prognostic relevance WT: Control lung; KRAS: Lung tumors expressing KRAS G12D; KRAS STAT3 KO: Lung tumors expressing KRAS G12D- STAT3 deficient; tumors of four mice pooled per sample

RNA-SEQ analysis of pancreatic ductal adenocarcinoma tumours in Pdx1-Cre;lsl-KRas[G12D] (KC), Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM] (KMC), Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM];c-Myc[fl/+] (KMC-Mycfl/+), and Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM];Zbtb17[fl/fl] mice (KMC-Miz1fl/fl)

Project description:Activation of endogenously expressed KRas[G12D] in the pancreas of mice gives rise primarily to early stage PanIN lesions, however such lesions can occasionally progress to end-stage ductal adenocarcinoma (PDAC). Progression of KRas[G12D]- initiated lesions to PDAC is accelerated by modest expression of MYC from the Rosa26 locus. Deletion of 1 copy of endogenous c-Myc or both copies of endogenous Zbtb17 (aka Miz1), slows progression to PDAC and extends healthful survival of Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM] (KMC) mice. Tumours were removed from mice with all 4 genotypes and validated by histological examination prior to RNA-SEQ analysis.

Mutation-specific and common phosphotyrosine signatures of KRAS G12D and G13D alleles

Project description:KRAS is one of the most frequently mutated genes across all cancer subtypes. Two of the most frequent oncogenic KRAS mutations observed in patients result in glycine to aspartic acid substitution at either codon 12 (G12D) or 13 (G13D). Although the biochemical differences between these two predominant mutations are not fully understood, distinct clinical features of the resulting tumors suggest involvement of disparate signaling mechanisms. When we compared the global and phosphotyrosine proteomic profiles of isogenic colorectal cancer cell lines bearing either G12D or G13D KRAS mutation, we observed both shared as well as unique signaling events induced by the two KRAS mutations.

KRAS WT and G12D overexpression RNA-seq

Project description:KRAS is an important oncogene in cancer. Long noncoding RNAs (lncRNAs) have been characterized to be involved in various types of cancer. In this study, we investigated the functions of KRAS-responsive lncRNAs in cancer. We perfomed the RNA-seq to examine the lncRNA expression after overexpession of KRAS WT and G12D in H1299 cells.

Isogenic mouse model of Kras G12D mutation in Acute Lymphoblastic Leukemia

Project description:RAS-MAPK activating mutations in NRAS, KRAS and PTPN11 were present in 24/55 (44%) cases in our series of diangosis and relapsed ALL. To evaluate the specific role of RAS-MAPK activating mutations in chemotherapy resistance in ALL we used primary isogenic leukemia cells expressing either Kras wild type or a mutant oncogenic form of Kras (Kras G12D) Mechanistically, functional dissection of Kras wild type and mutant Kras (Kras G12D) isogenic ALL cells demonstrated induction of methotrexate resistance, but also improved response to vincristine, in mutant Kras-expressing ALL cells. These results pave the road for the development of tailored personalized therapies for the treatment of relapsed ALL
