Project description:This study explore the role of the Myc oncogene in liver injury, in particular for the determination of the cellular programme involved in tissue repair and normalization after injury, a process that is blocked by Myc deregulation. The first objective of this study is to define the transcriptional profile of mouse livers 12 days after injury with or without MycER activation. The second objective is to determine the trancriptionl signature at 1,2,3,7 days after MycER was inactivated in pre injured liver to monitor its normalization.
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.
Project description:Aim: To determine RNA expression levels in the heart of mice 4 hours post Myc activation. Hearts were isolated from 15 day old wild-type (R26+/+) and R26CAG-c-MycERT2/+ mice following 4 hours of MycER activation via administration of (Z)-4-hydroxytamoxifen. Hearts were isolated from adult TetO-HRas; Myh6-tTA; R26CAG-c-MycERT2/+ and TetO-HRas; Myh6-tTA following 4 weeks of oncogenic H-Ras activation (Doxycycline withdrawal) and following 4 hours of MycER activation via administration of (Z)-4-hydroxytamoxifen.
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:Aim: To determine RNA expression levels in various tissues of mice 4 hours post Myc activation. Tissues were isolated from adult wild-type (R26+/+) and R26CAG-c-MycERT2/+ mice following 4 hours of MycER activation via administration of (Z)-4-hydroxytamoxifen.
Project description:Aim: To determine RNA expression levels in heart tissues of mice 4 post Myc activation. Mice were either untreated or systemically infected with a cardiomyocyte specific adeno associated virus (AAV9) at 4 to 6 weeks of age. Cardiomyocytes were isolated from adult mice that were either untreated or 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.
Project description:MCF10A MycER cells were grown either on 2D monolayer culture in the presence of complete growth medium, in the absence of EGF and insulin or in 3D Matrigel culture for 20 days to form acinar structures. MycER was activated with 4-hydroxytamoxifen (4-OHT) in all samples for 2 or 48 h. Control cells were treated with ethanol. The aim of the study was to explore the effect of different growth conditions on gene expression changes in response to c-Myc activation.
Project description:Aim: To determine Myc binding sites in mouse heart and liver, 4 hours post MycER activation. c-Myc ChIP sequencing performed on chromatin isolated from hearts and livers harvested from wild-type (R26+/+) and R26CAG-c-MycERT2/+ mice 4 hours post administration of (Z)-4-hydroxytamoxifen.
Project description:Aim: To determine RNA Pol II binding sites in mouse heart and liver, 4 hours post MycER activation. Pol II ChIP sequencing performed on chromatin isolated from hearts and livers harvested from wild-type (R26+/+) and R26CAG-c-MycERT2/+ mice 4 hours post administration of (Z)-4-hydroxytamoxifen.
