Expression data from mammary epithelia and mammary fibroblasts from mice with and without epithelial KrasG12D and with and without stromal p53 deletion

Project description:p53 is a known tumor suppressor. We have found that stromal p53 regulates breast cancer development, the immune landscape, and survival in an oncogene specific manner when comparing the epithelial oncogenes ErbB2 and KrasG12D In this dataset, we have evaluated mammary epithelia from mice with and without epithelial KrasG12D and with and without stromal p53 deletion. We have also evaluated mammary fibroblasts from mice with and without epithelial KrasG12D and with and without stromal p53 deletion.

Single cell RNA-seq reveals heterogeneity and hierarchy of mouse mammary epithelia

Project description:The mammary epithelia are mainly composed of two distinct lineages, the basal and luminal cells. Due to the limitation of traditional transcriptome analysis of bulk mammary cells, the hierarchy and heterogeneity of mammary cells within these two lineages remain unclear. Hence, we have performed single cell RNA-seq on mammary epithelial cells of virgin and pregnant mice. Based on the respective gene expression profiles, we found mammary cells are highly heterogeneous and can be classified into distinct subgroups with signature markers. Besides, we identified and verified a rare CDH5+ subpopulation of basal lineage as quiescent mammary gland stem cells (MaSCs). Furthermore, knockout of Cdh5 in mouse mammary cells via CRISPR-Cas9 significantly impairs cell stemness and promotes the cell differentiation to luminal lineage. In addition, via pseudo-temporal analysis, we reconstructed the mammary epithelia developmental trajectory and revealed the relevant changes of gene expression and biological functions of mammary cells along the developmental process.

mRNA expression pattern of KrasG12D mice with acute pancreatitis compared with wild-type mice without acute pancreatitis

mRNA expression pattern of KrasG12D mice with acute pancreatitis compared with wild-type mice without acute pancreatitis

Project description:Transgenic KrasG12D mice can recapitulate pancreas intra-epithelial neoplasia (PanIN). Caerulein is a cholecystokinin analogue and induces acute pancreatitis when injected intra-abdominally. Caerulein-induced acute pancreatitis will accelerate PanIN progression in KrasG12D mice. We compared mRNA profile changes between KrasG12D mice with acute caerulein-induced pancreatitis and wild-type mice without acute pancreatitis. The experiment had two groups. Experiment group: KrasG12D mice with acute caerulein-induced pancreatitis (N=6). Three mice in experiment group received 1-week caerulein injection, and the other three mice received 2-week caerulein injection. All experiment group mice started to receive caerulein injection at 1-month of age, and were sacrificed at the last day of caerulein injection. Control group: wild-type mice without acute pancreatitis (N=6). The mice were sacrificed at 1.5-month of age. Whole pancreas tissue lysate samples were subjected to mRNA array assay.

Temporal Transcriptional Profiling in response to cMYC and KrasG12D Expression and Inactivation in In Vitro Cultured Primary Mammary Epithelial Cells of Adult Virgin Mice

Project description:Mammary glands from 8 week old, female, virgin GEMM MMTV-rtTA/TetO-MYC/TetO-KrasG12D mice were dissociated into single cells and seeded into matrigel matrix for in vitro culture. To determine the gene expression changes which occur upon oncogene induction 5 days after seeding doxycycline was added to the media for 5 days, and then removed. Samples were taken of the following populations: 5 days on, 5 days on/7days off and never induced.

Transcription profiling of pancreata from Ptf1a-Cre;LSL-KrasG12D and Ptf1a-Cre;LSL-KrasG12D;RelAfl/fl mice

Project description:Oncogene-induced senescence in early mPanIN lesions depends on intact RelA function in vivo. We investigated the difference in gene expression between KrasG12D pancreata with and without deletion of RelA. Pancreata from 7 day old mice were prepared, RNA was isolated and Affymetrix microarray expression analysis was performed.

Expression data comparing Rb/p53 and p53 deficient mammary tumors and normal mammary tissue

Project description:To investigate the impact of combined Rb and p53 loss in mammary tumorigenesis, we used transgenic and viral approaches to delete Rb and p53 floxed alleles specifically in the mouse mammary epithelium. Although MMTV-Cre (NLST) targets stem/bi-potent progenitors in the mammary gland, a subset of MMTV-Cre:Rbf/f;p53f/f mice developed non-mammary tumors. Thus, freshly isolated primary mammary epithelial cells from these animals were transplanted into the mammary fat pads of immunodeficient mice and monitored for tumor formation. In addition, primary MECs were isolated from Cre-negative Rbf/f;p53f/f mice, infected with Ad-Cre followed by orthotopic transplantation. In all these cases, resulting tumors shared similar spindle-shape histology, expressed high levels of vimentin, a mesenchymal marker, but not E-cadherin, a luminal marker, and were classified as adeno-sacrcomatoid/spindle-cell/mesenchymal-like breast cancer. We used microarrays to detect differentially expressed genes in the Rb/p53 double-knock-out vs p53 single deletion or normal mammary tissue.

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

Project description: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.
