Project description:To investigate the differentially expressed genes and the pathways they might alter upon loss of MUC16 and subsequent perturbation of its downstream signaling We performed gene expression profiling analysis using data obtained from RNA-seq of the two different conditions (WT versus MUC16-knockout) (three replicates each).
Project description:Alternative splicing is a key event to human transcriptome and proteome diversity and complexity. Recent evidence suggests that pancreatic cancer might possess particular patterns of splice variation that influence the function of individual genes contributing to tumour progression in this disease. The identification of new pancreatic cancer-associated splice variants would offer opportunities for novel diagnostics and potentially also represent novel therapeutic targets. In this dataset, we investigated the alterations in the splicing machinery in pancreatic adenocarcinoma (PDAC) specimens with full clinicopathological details, in comparisons to adjacent pancreatic tissues and normal tissues from donors.
Project description:With the advent of cancer immunotherapy, intense investigation has been focused on tumor-infiltrating immune cells. With only a fraction of patients responding to these new therapies, a better understanding of all elements of the tumor microenvironment (TME) that may influence therapeutic outcome is needed. Stromal elements of the TME, chiefly fibroblasts, have emerged as potential contributors to tumor progression and most recently resistance to immunotherapy, but their precise composition and clinical relevance remain incompletely understood. Here we use single-cell transcriptomics to chart the fibroblastic landscape during pancreatic ductal adenocarcinoma (PDAC) progression in animal models, identifying two healthy tissue fibroblast subsets that co-evolve along individual trajectories into four subsets of carcinoma-associated fibroblasts (CAFs).

Project description:Doublecortin-like kinase 1 (Dclk1) is known as a cancer stem cell marker of pancreatic ductal adenocarcinoma (PDAC). But the functional evidence to define the stem cell activity of these cells within tumors has not been explored. We compared the gene expression profiles of Dclk1-positive and -negative PDACs cells.
Project description:Analysis of myofibroblast ablation at the gene expression level of PDAC tumors. Total RNA optained from pancreas of PDAC mice with and without aSMA myofibroblast ablated In addition, late stage aSMA ablated mice were treated with anti-CTLA4 treatment
