Longitudinal analysis of pancreatic adenocarcinoma development reveals transient gene expression signatures

Project description:We performed a transcriptome time-course analysis of genetically tagged human PDAC cells reprogrammed into a pluripotent stem cell-like line (10-22 cells) through the progression from PanINs to PDAC in mice. The results were validated using the Cancer Genome Atlas (TCGA) PDAC dataset, human clinical PanIN/PDAC tissues, and well-established murine PDAC model. Human normal pancreatic ductal epithelial cell line (H6C7) and PDAC cell lines (Miapaca2, Aspc1) are used for functional validation of HBP1. Pathways for extracellular vesicle transport pathways and neuronal cell differentiation were derepressed in the progression of PanINs to PDAC. Analysis of transcription factor (TF) motifs at dynamically expressed genes revealed roles for HBP1 and BACH during PDAC progression and their inverse correlations with PDAC patients' prognosis. Notably, we detected gene activity changes that were transient during PDAC progression. Our longitudinal analysis provides insights into networks underlying PDAC progression and pathogenesis.

Ito2019 - gefitnib resistance of lung adenocarcinoma caused by MET amplification

Project description:The model is based on publication: Mathematical analysis of gefitinib resistance of lung adenocarcinoma caused by MET amplification Abstract: Gefitinib, one of the tyrosine kinase inhibitors of epidermal growth factor receptor (EGFR), is effective for treating lung adenocarcinoma harboring EGFR mutation; but later, most cases acquire a resistance to gefitinib. One of the mechanisms conferring gefitinib resistance to lung adenocarcinoma is the amplification of the MET gene, which is observed in 5–22% of gefitinib-resistant tumors. A previous study suggested that MET amplification could cause gefitinib resistance by driving ErbB3-dependent activation of the PI3K pathway. In this study, we built a mathematical model of gefitinib resistance caused by MET amplification using lung adenocarcinoma HCC827-GR (gefitinib resistant) cells. The molecular reactions involved in gefitinib resistance consisted of dimerization and phosphorylation of three molecules, EGFR, ErbB3, and MET were described by a series of ordinary differential equations. To perform a computer simulation, we quantified each molecule on the cell surface using flow cytometry and estimated unknown parameters by dimensional analysis. Our simulation showed that the number of active ErbB3 molecules is around a hundred-fold smaller than that of active MET molecules. Limited contribution of ErbB3 in gefitinib resistance by MET amplification is also demonstrated using HCC827-GR cells in culture experiments. Our mathematical model provides a quantitative understanding of the molecular reactions underlying drug resistance.
