RNA-seq to investigate impact of treatment of KRAS mutant NCI-H2009 lung adenocarcinoma cells with the multi-ERBB inhibitor Neratinib

ABSTRACT: KRAS mutation is widely presumed to confer independence from upstream RTK signalling, however emerging evidence from mouse models of lung cancer suggests that ERBB RTKs may amplify signalling through RAS isoforms and participate in mutant RAS-driven lung cancer. This is one of 3 datasets where we examined the transcriptional impact of treatment of KRAS mutant human lung cancer cell lines with the multi-ERBB inhibitor Neratinib

KRAS is the most frequently mutated driver oncogene in human adenocarcinoma of the lung. There are presently no clinically proven strategies for treatment of KRAS-driven lung cancer. Activating mutations in KRAS are thought to confer independence from upstream signaling; however, recent data suggest that this independence may not be absolute. We show that initiation and progression of KRAS-driven lung tumors require input from ERBB family receptor tyrosine kinases (RTKs): Multiple ERBB RTKs are ...[more]

Dual inhibition of KRASG12D and pan-ERBB is synergistic in pancreatic ductal adenocarcinoma

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer with a low survival rate. Recently, new drugs that target KRASG12D, a common mutation in PDAC, have been developed. We studied one of these compounds, MRTX1133, and found it was specific and effective at low nanomolar concentrations in patient-derived organoid models and cell lines harboring KRASG12D mutations. Treatment with MRTX1133 upregulated the expression and phosphorylation of EGFR and HER2, indicating that inhibition of ERBB signaling may potentiate MRTX1133 anti-tumor activity. Indeed, the irreversible pan-ERBB inhibitor, afatinib, potently synergized with MRTX1133 in vitro, and cancer cells with acquired resistance to MRTX1133 in vitro remained sensitive to this combination therapy. Finally, the combination of MRTX1133 and afatinib led to tumor regression and longer survival in orthotopic PDAC mouse models. These results suggest that dual inhibition of ERBB and KRAS signaling may be synergistic and circumvent the rapid development of acquired resistance in patients with KRAS mutant pancreatic cancer.

KRAS and YAP1 converge to regulate EMT and tumor survival

Project description: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 expressed 15,294 open reading frames in a human KRAS-dependent colon cancer cell line engineered to express an inducible KRAS-specific shRNA. We found 147 genes that promoted survival in the setting of KRAS suppression. In this model, the transcriptional co-activator YAP1 rescued cell viability in KRAS-dependent cells upon suppression of KRAS and was required for KRAS-induced cell transformation. Acquired resistance to Kras suppression in a Kras-driven murine lung cancer model also involved increased YAP1 signaling. KRAS and YAP1 converge on the transcription factor FOS and activate a transcriptional program involved in regulating the epithelial-mesenchymal transition (EMT). Together, these findings implicate transcriptional regulation of EMT by YAP1 as a significant component of oncogenic RAS signaling Three biological replicates of primary lung adenocarcinoma cells derived from the Kras Lox-STOP-Lox-G12D;p53flox/flox (KP) mouse lung cancer model into which a doxycycline-inducible shRNA targeting Kras expressed from the 3’UTR of GFP was introduced (KP-KrasA cells) were analyzed at timepoints (days) D0, D4, and D21.

Comparison of KrasG12D/WT;p53Fx/Fx and KrasG12D/G12D;p53Fx/Fx MEFs

Project description:Microarray expression data generated to compare the biological impact of KrasG12D allelic duplication in p53null mouse embryonic fibroblasts (MEFs). The RAS/MAPK-signalling pathway is frequently deregulated in non-small cell lung cancer (NSCLC), often through activating mutations in KRAS. Mouse models demonstrated that activation of a single endogenous mutant Kras allele is sufficient to promote lung tumour formation, but acquisition of other genetic alterations is required for malignant progression. Using a well-established lung cancer mouse model we recently demonstrated that advanced KrasG12D-driven spontaneous tumours frequently exhibit enhanced MAPK signalling and KrasG12D allelic enrichment (KrasG12D/Kraswild-type>1), implying that mutant Kras copy gains are positively selected during lung cancer progression. To compare the oncogenic impact of a single mutant allele versus additional mutant Kras copy gain, we carried out a comprehensive analysis of mutant Kras homozygous and heterozygous MEFs and lung cancer cells and show that these genotypes are phenotypically distinct. Title: Mutant Kras copy number defines metabolic reprogramming and therapeutic susceptibilities Authors: Emma M Kerr, Edoardo Gaude, Frances K Turrell, Christian Frezza and Carla P Martins For MEF generation, KrasLSL-G12D/+ ;p53Fx/Fx mixed background (C57Bl/6/129/Sv) animals were interbred and embryos collected at day E12.5 to overcome KrasLSL-G12D/G12D embryonic lethality and Cre-mediated recombination performed immediately after MEF generation. Cells were cultured in DMEM supplemented with 10% FBS, 2 mM L-Glutamine for one passage and then infected with adenovirus-Cre (5âÃâ107âplaque-forming units/1 x 106 cells). Recombination of LoxP sites was confirmed by PCR analysis. Three independent embryos per genotype were analysed using GPL6887 Illumina MouseWG-6 v2.0 expression beadchip.

PTEN-deficiency in luminal MMTV-ErbB-2 mouse model results in dramatic acceleration in mammary tumorigenesis/metastasis

Project description:Overexpression and/or amplification of the ErbB-2 oncogene, as well as inactivation of the tumor suppressor PTEN, are two important genetic events in human breast carcinogenesis. To address the biological impact of conditional inactivation of PTEN on ErbB-2-induced mammary tumorigenesis, we generated a novel transgenic mouse model that utilizes the MMTV promoter to directly couple expression of activated ErbB-2 and Cre recombinase to the same mammary epithelial cell (MMTV-NIC). Disruption of PTEN in the mammary epithelium of the MMTV-NIC model system dramatically accelerated the formation of multifocal and highly metastatic mammary tumors, which exhibit homogenous pathology. PTEN-deficient/NIC tumorigenesis was associated with an increase in angiogenesis. Moreover, inactivation of PTEN in the MMTV-NIC mouse model resulted in hyperactivation of the PI3K/Akt signalling pathway. However, like the parental strain, tumors obtained from PTEN-deficient/NIC mice displayed histopathological and molecular features of the luminal-like subtype of breast cancer. Taken together, our findings provide important implications in understanding the molecular determinants of mammary tumorigenesis driven by PTEN deficiency and ErbB-2 activation, and could provide a valuable tool for testing the efficacy of therapeutic strategies that target these critical signalling pathways.

Gene Regulation by microRNA-16 forced expression in ErbB-2 positive murine breast cancer cells.

Project description:miR-16 is a potent tumor suppressor in ErbB-2 positive breast cancer. The primary objetive of this study was to identify previously uncharacterized putative mRNA targets of miR-16 in ErbB-2 postitive breast cancer cells. To achieve our objective we studied the effects of exogenously expressed miR-16 on the gene expression profile of primary cultures of ErbB-2 positive murine breast cancer tumors. The C4HD tumor line displays high levels of estrogen receptor and progesterone receptor, overexpresses ErbB-2 and ErbB-3, exhibits low ErbB-4 levels, and lacks EGF-R expression.

High efficacy of combined MEK Inhibitor Trametinib and RTK Inhibitor Anlotinib Therapy in KRAS-Mutant Lung Cancer

Project description:Oncogenic KRAS mutations frequently detected in non-small cell lung cancer (NSCLC)1,2, have been considered undruggable until recent development of inhibitors, e.g., sortorasib, adagrasib or divarasib, specifically targeting KRASG12C 3-6. However, it still remains as a big challenge to target all the KRAS mutants besides KRASG12C 2,7,8. We here found that MEK inhibitor trametinib treatment results in the feedback activation of multiple receptor tyrosine kinases (RTKs) in NSCLC, and combined treatments with trametinib and anlotinib, a pan-RTK inhibitor, effectively inhibited KRAS-mutant lung cancer progression.

A receptor tyrosine kinase network comprised of FGFRs, EGFR, ERBB2, and MET drives growth and survival of HNSCC cell lines.

Project description:We have previously shown that some gefitinib insensitive head and neck squamous cell carcinoma (HNSCC) cell lines exhibit dominant autocrine fibroblast growth factor receptor (FGFR) signaling. Herein, we deployed a whole genome loss-of-function screen to identify genes whose knockdown potentiated the inhibitory effect of the FGFR inhibitor, AZ12908010, in HNSCC cell lines. Three HNSCC cell lines expressing a genome-wide shRNA library were treated with AZ8010 and the abundance of shRNA sequences was assessed by deep sequencing. Synthetic lethal hits were validated through use of specific inhibitors and independent shRNAs. We found that multiple alternate receptors provided protection from FGFR inhibition, including the receptor tyrosine kinases (RTKs), epidermal growth factor receptor 2 (ERBB2) and hepatocyte growth factor receptor (MET). We showed that specific knockdown of either ERBB2 or MET in combination with FGFR inhibition led to increased inhibition of growth relative to FGFR tyrosine kinase inhibitor (TKI) treatment alone. These results were confirmed using specific small molecule inhibitors of either ERBB family members or MET. Moreover, the combination of FGFR, MET and ERBB family inhibitors showed the largest inhibition of growth as compared to the double combinations. These results reveal a role for alternate RTKs in maintaining pro-growth and survival signaling in HNSCC cells in the setting of FGFR inhibition. Thus, improved therapies for HNSCC patients could involve rationally designed combinations of TKIs targeting FGFR, ERBB family members and MET. Using a genome-wide shRNA library in combination with deep sequencing, we screened for gene targets that were synthetic lethal with the FGFR inhibitor, AZ12908010 in HNSCC cells. Three HNSCC cell lines were screened in triplicate and the abundance of shRNA sequences in drug treated cells was compared to control treated cells.
