Project description:Pooled KRC (LSL-KrasG12D; Rb1L/L; Pdx1-Cre: oncogenic Kras and deleted Rb1 in the pancreas) cells derived from 2 month old mice were compared to pooled KC (LSL-KrasG12D; Pdx1-Cre: oncogenic Kras in the pancreas) cells derived from 8 month old mice.
Project description:To investigate the role of SHP2 (Ptpn11) in pancreatic carcinogenesis, murine pancreatic whole tissue RNA samples of 9 week old mice with the genotypes Ptf1a-Cre;LSL-KrasG12D (ID-labels Kxxx) and Ptf1a-Cre;LSL-KrasG12D;Ptpn11fl/fl (ID-labels Mxxxx) were analyzed by microarray.
Project description:Gene expression analysis of pancreatic tumors from genetically engineered mice (Pdx-Cre;LSL-KRASG12D;TGFBRIIf/f) with depletion of aSMA+ or FAP+ cells. The pancreas tumors were harvested and analysed for gene expression profiles comparisons. Overall design: Total RNA was isolated from the pancreas tumors of 3 PKT FAP control mice, 3 PKT FAP depleted mice, 3 PKT aSMA control mice, 3 PKT aSMA depleted mice
Project description:Genetically engineered mice developed spontaneous pancreas cancer (Pdx-Cre;LSL-KRASG12D;P53Mut). Mice were also engineered to develop similar spontaneous pancreas cancer without Twist or Snail (conditional gene knockout). The pancreas tumors were harvested and analysed for gene expression profiles comparisons. Total RNA was isolated from the pancreas tumors of 2 mice with wild-type Twist and Snail, from 2 mice without Twist expression in the pancreas, and from 2 mice without Snail expression in the pancreas.
Project description:These experiments aimed to determine the global gene expression patterns in p120WT, p120HET, and p120NULL cells in the context on oncogenic mutant KrasG12D Overall design: p120ctn was deleted using in vitro lentiviral Cre recombinase in pancreatic ductal cells isolated from LSL-KrasG12D;Ctnnd1wt/wt (KC-p120ctnWT), LSL-KrasG12D;Ctnnd1fl/wt (KC-p120ctnHET) , and LSL-KrasG12D;Ctnnd1fl/fl (KC-p120ctnNULL) mice.
Project description:Transcriptional profiling of mouse Prostate cancer cells comparing Pbsn-Cre LSL-KrasG12D P53L/L cells with Pbsn-Cre LSL-BrafV600E P53L/L cells, and to determine the effects of Kras or Braf mutantion on murine PCa gene expression. Overall design: Three-condition experiment, Pbsn-Cre LSL-KrasG12D P53L/L cells vs. Pbsn-Cre LSL-BrafV600E P53L/L cells vs. Pbsn-Cre P53L/L cells: 2 wild type replicates, 2 KrasG12D mutant replicates and 2 BrafV600E mutant replicates.
Project description:This study used Illumina RNA-sequencing to examine transcriptomic profile of mice with Klf5 knockout in context of oncogenic Kras expression. The study analyzed total RNA extracted from pancreas of mice 2 days after cerulein-induce pancreatitis. In addition, this study include 2 biological replicate of mice with each of the following genotypes: Ptf1aCreERTM, Ptf1aCreERTM;Klf5fl/fl, Ptf1aCerERTM;LSL-KrasG12D, and Ptf1aCreERTM;LSL-KrasG12D;Klf5fl/fl. Overall design: Transcriptomic profiling of pancreata from 2 Ptf1aCreERTM mice, 2 Ptf1aCreERTM;Klf5fl/fl mice, 2 Ptf1aCerERTM;LSL-KrasG12D mice, and 2 Ptf1aCreERTM;LSL-KrasG12D;Klf5fl/fl mice 2 days after cerulein-induced pancreatitis.
Project description:Analysis of primary PDAC cells established from Pdx-1CreAPCL/+p53L/L and Pdx-1Crep53L/L mice. APC haploinsufficiency combined with P53 loss in the pancreas drives MCN progression in mice. Results provide insight into molecular mechanisms invloved in the MCN formation of Pdx-1Cre APCL/+P53L/L mice. Pdx-1CreAPC+/LP53L/L PDAC cell lines and 2 Pdx-1CreP53L/L ductal cell lines were analyzed.
Project description:Purpose: determine RNA expression differences in an unbiased fashion between UPS tumors derived from LSL-KrasG12D;Trp53-/- (KP) mice, and UPS tumors derived from LSL-KrasG12D;Trp53-/-;Epas1-/- (KPH2) mice. Epas1 encodes HIF-2alpha protein. RNA-seq was performed on KP (n = 4) and KPH2 (n = 4) derived UPS tumors using Illumina HiSeq 2000.
Project description:A subset of human pancreatic ductal adenocarcinoma cells (PDACs) is characterized by high Fosl1 expression and Fosl1 is linked to the control of pro-inflammatory pathways and growth of PDAC cells. To mimick the human disease in mice (> 90% of PDAC patients harbour Kras mutations) the mutated LSL-KrasG12D allele was combined with the pancreas specific Cre recombinase Ptf1aCre (p48Cre). The two pancreatic cancer cell lines (Ptf1aCre, LSL-KrasG12D/+) were isolated from these mice and used for transcriptomics studies. The two different murine pancreatic cancer cell lines (Ptf1aCre, LSL-KrasG12D) were treated with two different Fosl1 siRNAs and one control siRNA, each. 72h after transfection a sufficient knockdown was tested by immunoblotting and qPCR. Total mRNA was isolated and checked for integrity. According to manufacture's recommendation the samples were subjected to microarray analysis using the Affymetrix Mouse Gene ST 1.0 array chip to discover differentially expressed genes.
