Project description:Examination of effect of stable DDR1 knockdown by shRNA on transcriptional profile in BXPC3 cell line to understand role of DDR1 in tumorigenesis. Transcriptional profiles of parental BXPC3 cell line was compared to BXPC3 cells stably transfected with non-target shRNA or DDR1 shRNA, N=3 for each condition.

Project description:Purpose: The goals of this study are to compare mammary tumor transcriptome profiling with or without DDR1 in immunocompetent mice in an unbiased way. Methods: In vitro samples: DDR1 WT or KO in vitro cultured E0771 cells were sequenced. Rag1-/- samples: DDR1 WT or KO E0771 cells were injected in Rag1-/- mice, and tumors were harvested and sequenced. C57BL/6 samples: DDR1 WT or KO E0771 cells were firstly inoculated into Rag1-/- mice. When tumor volume reached approximately 200~300 mm3 (usually 20 days after inoculation), 60 mg of tumor organoid were transplanted to WT C57BL/6 mice. Tumor samples were collected on day 4 after transplantation for RNA-seq. Antibody treatment samples: DDR1 KO E0771 cells were reconstituted with human DDR1, then injected into C57BL/6 mice. Isotype control IgG or anti-hDDR1 ECD antibody treatment (10mg/kg intrutumural) started when tumor volume reached approximately 100 mm3. Tumor samples were collected on day 6 after treatment for RNA-seq. Results: Approximately 50 million sequence reads were obtained per sample and identified more than 20,000 transcript isoforms. Conclusions: The RNA-seq results represents the detailed analysis of DDR1 WT/KO mammary tumor transcriptomes in immunocompetent mice C57BL/6.

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a highly desmoplastic, aggressive cancer, frequently progressing and spreading by liver metastasis. Cancer-associated fibroblasts (CAF), extracellular matrix (ECM), and type I collagen (Col I) support or restrain PDAC progression and may impede blood supply and nutrient availability. The dichotomous role of the stroma in PDAC, and the mechanisms through which it influences patient survival and enables desmoplastic cancers to escape nutrient limitation remain poorly understood. Here we show that matrix metalloprotease (MMP)-cleaved or intact Col I (cCol I and iCol I, respectively) exert opposing effects on PDAC bioenergetics, macropinocytosis (MP), tumor growth and metastasis. While cCol I activates DDR1 (discoidin domain receptor-1)-NF-kB-p62-NRF2 signaling to promote PDAC growth, iCol I triggers DDR1 degradation and restrains PDAC growth. Patients whose tumors are iCol I enriched and DDR1 and NRF2 low have improved median survival compared to those with high cCol I, DDR1 and NRF2. Inhibition of DDR1-stimulated NF-kB or mitochondrial biogenesis blocked tumorigenesis in wildtype mice but not in mice expressing MMP-resistant Col I. The diverse effects of the tumor stroma on PDAC growth, metastasis, and patient survival are mediated through the Col I-DDR1-NF-kB-NRF2-mitochondrial biogenesis pathway, presenting new therapeutic opportunities.

Project description:Patients diagnosed with hormone dependent breast cancer (HDBC) receive five or more years of adjuvant endocrine therapies (ETs). Adjuvant ETs delay relapse by targeting clinically undetectable micro-metastatic deposits, yet up to 50% of patients receiving ET relapse at a constant rate over the course of decades after surgery. The mechanisms driving these clinical dynamics are largely unknown but likely involve dormancy. We developed two approaches to study the fate of dormant cells in long-term experiments. Firstly, we profiled samples from late relapse (10-35 yrs.) and patients treated with 16-44 months of neoadjuvant ETs until progression to dissect the contribution of genetic and transcriptional changes to tumour awakening. Next, we developed a first of its kind in vitro evolutionary study to systematically record adaptive strategies of individual lineages in unperturbed parallel experiments through several months. Collectively our data demonstrate that ETs induce a heritable cell state transition into dormancy via epigenetic reprogramming. Single lineages with divergent phenotypes awaken unpredictably via epigenetic erosion. Targeting the dormant epigenome shows promising activity against adapting cancer cells. Overall, this study uncovers the contribution of epigenetic adaptation to the evolution of resistance to ETs with profound implications for breast cancer.

Project description:The clinical management of metastatic colorectal cancer (mCRC) faces major challenges. For instance, patients harbouring oncogenic mutations in RAS signalling do not respond to anti-EGFR targeted treatment. Therefore, RAS-independent therapies are needed. Interestingly nilotinib, a clinically approved drug for chronic myeloid leukaemia, inhibits human CRC cell invasion in vitro and reduces their metastatic potential in intrasplenic tumour mouse models. Nilotinib acts by inhibiting the kinase activity of DDR1, a receptor tyrosine kinase for collagens, which we identified as a RAS-independent inducer of CRC metastasis. Using quantitative phosphoproteomics, we identified BCR as a new DDR1 substrate and demonstrated that nilotinib prevents DDR1-mediated BCR phosphorylation on Tyr177, which is important for maintaining -catenin transcriptional activity necessary for tumour cell invasion. DDR1 kinase inhibition also reduced the invasion of patient-derived metastatic and circulating CRC cell lines.
