Project description:Zeb1, a zinc finger E-box binding homeobox epithelial-mesenchymal (EMT) transcription factor, confers properties of ‘stemness’, such as self-renewal, in cancer. Yet little is known about the function of Zeb1 in adult stem cells. Here, we used the hematopoietic system, as a well-established paradigm of stem cell biology, to evaluate Zeb1 mediated regulation of adult stem cells. We employed a conditional genetic approach using the Mx1-Cre system to specifically knockout (KO) Zeb1 in adult hematopoietic stem cells (HSCs) and their downstream progeny. Acute genetic deletion of Zeb1 led to rapid onset thymic atrophy and apoptosis driven loss of thymocytes and T cells. A profound cell-autonomous self-renewal defect and multi-lineage differentiation block was observed in Zeb1 KO HSCs. Loss of Zeb1 in HSCs activated transcriptional programs of deregulated HSC maintenance and multi-lineage differentiation genes, and of cell polarity, consisting of cytoskeleton, lipid metabolism/lipid membrane and cell adhesion related genes. Notably, Epithelial cell adhesion molecule (EpCAM) expression was prodigiously upregulated in Zeb1 KO HSCs, which correlated with their enhanced cell survival capacity and diminished differentiation in transplantation. Thus, Zeb1 acts as a crucial transcriptional regulator in hematopoiesis, co-ordinating HSC self-renewal and multi-lineage differentiation fates, in part, via EpCAM repression.

Project description:Purpose: Characterize the gene expression profile of gastrocnemius muscle in wild type, ZEB1 and ZEB2 knock out mice subjected to 36 hours of fasting Methods: RNA sequencing of RNA from total gastrocnemius muscle after 36h of fasting from the three genotypes used in this study: ZEB1-control, ZEB1-KO, ZEB2-control, ZEB2-KO. Males and females were used from the four genotype (ZEB1flx/flx, ZEB1flx/flx;HSACre, ZEB2flx/flx, ZEB2flx/flx;HSACre). Results: Knockout of ZEB1 or ZEB2 results in differential gene expression in atrophic gastrocnemius muscle Conclusions: Comparison of wild type, ZEB1 and ZEB2 KO muscles displayed differential gene expression profiles after fasting

Project description:PABPN1L participates in the process of post-transcriptional regulation and degradation of maternal mRNA.So,we collect samples of each period from pabpn1l ko and wt female mice during different stages.Then, RNA was extracted and detected.Reverse transcription was performed on the samples that met the effective concentration.After quality inspection, build the library.GV oocytes, MII oocytes and zygotes were collected from three different PABPN1L KO or WT mice separately.

Project description:Differentiation of epithelial cells is strongly affected by transcription factors related to epithelial to mesenchymal-like progression. We used gene expression profiling to identify genes that are differentially regulated upon repression of the transcription factor Zeb1 (deltaEF1/Areb6). NM18 cells were transfected with non-silencing siRNA (ns-siRNA) or siRNA targeting Zeb1 (Zeb1 siRNA) for 48h. Experiments were performed as independent biological triplicate. Three non-silencing siRNA samples (GSM1322708, GSM1322709, and GSM1322710) were originally deposited in Series GSE54715. The samples were reanalyzed with the Zeb1 siRNA samples and the data is linked at the bottom of the Series record.
