Differentially expressed genes in KPC Cxcr2 KO vs KPC mouse PDAC

Project description:Recently, Bailey et al (2016, Nature) defined four subtypes of pancreatic cancer that are associated with distinct histopathological characteristics and differential survival, namely, Squamous, Pancreatic Progenitor, Immunogenic, and ADEX (Aberrantly Differentiated Endocrine eXocrine). We set out to assess by RNASeq whether loss of CXCR2 was significantly associated with a specific PDAC subtype. Pancreatic tumors were harvested from KPC or KPC Cxcr2-/- mice at endpoint (n=5 v 5), RNA prepared, and RNASeq analysis carried out. Reads were analysed using the bcbio-nextgen framework (https://bcbio-nextgen.readthedocs.org/en/latest/). After quality control and adaptor trimming, reads were aligned to the mouse genome build (UCSC mouse mm10) using STAR. Counts for known genes were generated using the function featureCounts in the R/Bioconductor package \Rsubread\. The R/Bioconductor package edgeR was used to identify differentially expressed genes.

Genes activated by 5-aza-dC (DAC) in pancreatic (KPC-Brca1) cancer-associated fibroblasts (CAFs)

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy that resists current treatments. To test epigenetic therapy against this cancer we used the DNA demethylating drug 5-aza-2’-deoxycytidine (DAC) in a KrasLSL-G12D; p53LSL-R270H/+; Pdx1-cre; Brca1flex2/flex2 (KPC-Brca1) mouse model of aggressive stroma-rich PDAC. In untreated tumors, we found globally decreased 5-methyl-cytosine (5mC) in malignant epithelial cells and in cancer-associated myofibroblasts (CAFs), and increased amounts of 5-hydroxymethyl-cytosine (5HmC) in CAFs, in progression from pancreatic intraepithelial neoplasia (PanIN) to PDAC. DAC further reduced DNA methylation and slowed PDAC progression, markedly extending survival in an early treatment protocol and significantly though transiently inhibiting tumor growth when initiated later, without adverse side effects. Escaping tumors contained areas of sarcomatoid transformation with disappearance of CAFs. Mixing-allografting experiments and proliferation indices showed that DAC efficacy was due to inhibition of both the malignant epithelial cells and the stromal CAFs. Expression profiling and immunohistochemistry highlighted DAC-induction of STAT1 in the tumors, and DAC plus gamma-interferon produced an additive anti-proliferative effect on PDAC cells. DAC induced strong expression of the testis antigen DAZL in CAFs. These data show that DAC is effective against PDAC in vivo and provide a rationale for future studies combining hypomethylating agents with cytokines and immunotherapy. Treatment of a short-term explant culture of cancer-associated fibroblasts (CAFs) from a KPC-Brca1 mouse pancreatic carcinoma, with 2 micromolar 5-aza-dC (decitabine; DAC) for 48 hours. The experiment includes 3 replicate plates untreated and 3 replicates treated.

Inhibition of ketohexokinase C isoform impairs the development of PDAC tumors

Project description:the genetic inactivation of Khk-C enhanced the survival of KPC-driven PDAC model even in absence of high fructose diet. Moreover Khk-C knock out decreased the viability of KPC organoids and cancer cells, the migratory capability of PDAC cells in vitro and the growth of KPC cells in vivo in a cell autonomous manner.

RNAseq of parental and neratinib resistant 5637 and OVCAR8 cells with or withour neratinib treatment

Project description:Pan-HER TKI neratinib has demonstrated clinical activity in patients with HER2-mutant cancers. However responses are heterogenoeus and not generally prolonged, suggesting de-novo and acquired resistance to neratinib. To study mechanisms of resistance to neratinib we generated neratinib resistant cells by gradual dose escalation until resistance was achieved and performed various analyses including RNAseq.
