In conclusion, whilst oncogenic KRAS mutation might activate Yap in other cell types, we could find no evidence for this in myoblasts because the expression of KRAS G12V expression did not change Yap/Taz activity in myoblasts and there was a limited overlap in gene expression between KRAS G12V and YAP1 S127A-driven tumours.
Disruption of Acvr1b in LSL-KRAS(G12D);Pdx1-Cre mice accelerated the growth of pancreatic IPMNs compared with LSL-KRAS(G12D);Pdx1-Cre mice, but did not alter growth of pancreatic intraepithelial neoplasias.
The K-Ras(V14I) mutation is a mild activating K-Ras protein; thus, we have used this model to study tumour susceptibility in comparison with mice expressing the classical K-Ras(G12V) oncogene.
Coactivation of BRAF(V600E) and KRAS(G12D) markedly reduced lung tumor numbers and overall tumo</span>r burden compared with activation of BRAF(V600E) alone.
Orthotopic implantation of PDCs carrying the activated Kras(G12D</span>)-allele and shRNA against p16(Ink4a) or Trp53 resulted in tumor growth, metastasis, and reduced survival of NSG mice.
We found that the deletion of Ink4a/Arf in K-Ras(G12D) expressing mice led to high expression of PDGF-D signaling pathway in the tumor and tumor-derived cell line (RInk-1 cells).
Both tumors develop in mice upon conditional deletion in melanocytes of Ink4a/Arf tumor suppressor genes with concomitant expression of oncogene H-Ras(G12V) and a known tumor antigen.
However, we identified a p14ARF exon 1beta missense germline mutation (G16D) in a melanoma-neural system tumour syndrome (CMM+NST) family and a 8474 bp germline deletion from 196 bp upstream of p14ARF exon 1beta initiation codon to 11233 bp upstream of exon 1alpha of p16(INK4A) in a family with five melanoma cases.
