Project description:Protein arginine methylation has been established an essential protein modification regulating cancer initiation and progression, but its implications in PDAC (Pancreatic ductal adenocarcinoma) still remains poorly elucidated. In this study, we characterized ADMA (asymmetric dimethylarginine)-bearing peptides in human pancreatic ductal epithelium cell line HPDE6c7 and PDAC cell line PANC-1 by a label-free quantitative proteomics combined with affinity purification.

Project description:Pancreatic ductal adenocarcinoma, caused by activating mutation in K-Ras, is an aggressive malignancy due to its early invasion and matastasis. Ral GTPases, negatively regulated by RalGAP, are activated downstream of Ras and play a crucial role in development and progression of pancreatic ductal adenocarcinoma. However, the underlying mechanisms remain unclear. We used microarrays to detail the global programme of gene expression underlying the human pancreatic ductal adenocarcinoma cell line, MIA PaCa-2 with RalGAPβ deficiency or not, and identified distinct classes of Ral activation-related mRNA.

Project description:Constitutive Kras and NF-kB activation is identified as signature alterations in human pancreatic ductal adenocarcinoma (PDAC). Here, we report that pancreas-targeted IKK2/beta inactivation inhibited NF-kB activation and completely suppressed PDAC development. Our findings demonstrated that NF-kB is required for development of pancreatic ductal adenocarcinoma that was initiated by Kras activation. Pancreatic tissue from 4 groups of mice were used in this project: (1) the pancreas normal appearance of Pdx1-cre;KrasLSL-G12D;IKK2/beta mice, (2) the normal pancreas of Pdx1-cre;KrasLSL-G12D mice, (3) the pancreatic lesion of pancreatic intraepithelial neoplasia (PanIN) of Pdx1-cre;KrasLSL-G12D mice, and (4) the pancreatic lesion of PDAC of Pdx1-cre;KrasLSL-G12D mice. Each group included three mice. RNA samples from mouse pancreas were hybridized on GeneChip Mouse Gene 1.0 ST arrays (Affymetrix). Group (1) and group (2) were compared, and group (2), group (3) and group (4) were compared.

Project description:Pancreatic ductal adenocarcinoma (PDAC) has one of the worst prognoses of any human malignancy and there are few human cellular models of disease progression. When human PDAC cells are injected into immunodeficient animals, they create tumors of the late stage from which they were derived. We hypothesized that if human pancreatic cancer cells were converted to pluripotency and then allowed to differentiate back into pancreas, the developmental progression would recapitulate early stages of the cancer. To that end, we have generated isogenic matched sets of induced pluripotent stem (iPS) cell-like lines from epithelial cells of human pancreatic tumors and from histologically normal epithelial cells at the resected pancreatic margins. Notably, when injected into immunodeficient mice, at low or high passages, a human pancreatic cancer iPS-like line, but not the corresponding margin iPS-like line, slowly generates intra-epithelial neoplasia (PanIN) ductal structures that typically reflect the early stages of human pancreatic cancer. The PanIN-like ducts can be isolated and cultured. They secrete protein products reflective of PanINs and provide new insights into underlying regulatory networks. An additional iPS-like line from histologically normal cells at a pancreatic resection margin, but containing a mutation that predisposes to PDAC, does not generate PanIN ductal structures. These studies demonstrate that iPS technology can be exploited to recapitulate early progression events of a human epithelial cancer. Study includes a single experiment (#10): a tumor-adjacent pancreatic tissue control (10N); tumor tissue (10C); IPS-transformed tissue control (10N12); and IPS-transformed tumor tissue (10C22).
