RNAseq of pancreatas from KRasG12D/RosaMycER+/- or KRasG12D/RosaMycER+/+ treated with Tamoxifen for 12h

ABSTRACT: Experiment designed to study the effect of 1 or 2 copies of deregulated myc on transcriptional profile during pancreatic cancer progression. In the KRasG12D/RosaMycER mouse model KRas and MycER are expressed exclusively in the pancreas, but MycER activity depends on Tamoxifen presence. RNAseq was preformed on pancreatas from KRasG12D/RosaMycER+/- or KRasG12D/RosaMycER+/+ mice treated 12 hours with Tamoxifen.
Project description:Experiment designed to study the effect of deregulated myc on pancreatic cancer progression and regression. In the KRasG12D/RosaMycER mouse model KRas and MycER are expressed exclusively in the pancreas, but MycER activity depends on Tamoxifen presence. RNAseq was preformed on pancreata from mice treated with Tamoxifen as follows: 1- Normal food. 2- Tamoxifen food 2 weeks. 3- Tamoxifen food 2 weeks, followed by normal food 1 day. 4- Tamoxifen food 2 weeks, followed by normal food 3 days.

Project description:Experiment designed to study the effect of deregulated myc on pancreatic cancer progression and regression. In the KRasG12D/RosaMycER mouse model KRas and MycER are expressed exclusively in the pancreas, but MycER activity depends on Tamoxifen presence. For this experiment a mouse was treated with Tamoxifen during 3 weeks, the pancreas was collected and the epithelial cells were grown in vitro in the presence of 4-OHT (4-Hydroxytamoxifen, active form of Tamoxifen). RNAseq were preformed on the cell line treated as follows: 1- 4-OHT all the time. 2- EtOH 6h. 3- EtOH 12h. 4- EtOH 18h.
Project description:A transgenic mouse model of Kras-driven lung adenocarcinoma, with reversible activation of Myc, was used to explore the effect of Myc activity on lipid metabolism in lung tumours. Gene expression analysis links lipid metabolism, transport and storage to Myc activity. Lung cells from adeno-cre infected R26LSL-CMER and LSL-KrasG12D; R26LSL-CMER mice were isolated 14 days post-treatment with (LSL-KrasG12D; R26LSL-CMER and R26LSL-CMER) or without (R26LSL-CMER only) tamoxifen. GFP positive cells were FACs sorted. To increase RNA yield, cells from two mice of the same genotype and treatment were combined. There were two biological replicates for each condition. Gene expression was compared between lung cells with inactive MycER and lung cells expressing active MycER plus or minus KRasG12D.
Project description:Aim: To determine RNA expression levels in heart tissues of mice 4 and 48 hours post Myc activation. Mice were systemically infected with a cardiomyocyte specific adeno associated virus (AAV9) at 4 to 6 weeks of age. Hearts were isolated from adult mice that had been infected with AAV9-Ccnt1 and were either Myh6-cre;R26CAG-c-MycERT2/+ or R26CAG-c-MycERT2/+ following 4 hours of MycER activation via administration of (Z)-4-hydroxytamoxifen. Hearts were isolated from adult mice that had been infected with either AAV9-Ccnt1 or AAV9-RFP and were R26CAG-c-MycERT2/+ 48 hours post a single injection of tamoxifen to induce MycER activity.
Project description:Analysis of MycER-BclXl-induced insulinoma in Fzd9 wt and knock out mice after three days of MycER activation Mice (n=4/genotype) were euthanized three days after tamoxifen inoculation and pancreatic islets were isolated and frozen at -80ºC until processing.
