Effect of Trp63 deletion on the developing vagina

ABSTRACT: Gene expression in the neonatal uterus and vagina from transformation related protein 63 (Trp63) conditional heterozygous and null mice was analyzed in order to identify upstream and downstream of Trp63 in the developing vagina. Differential gene expression between vaginal (Trp63 positive) and uterine (Trp63 negative) tissues should reflect both the upstream and downstream of Trp63 expression, whereas the comparison between conditional knockout and heterozygous vaginae should identify what is downstream of Trp63. Thus, the three-way comparison should identify what is upstream of Trp63. Total RNA was extracted from the Trp63 conditional heterozygous (Trp63 flox/wt ; Pax2-cre) uteri and vaginae, and Trp63 conditional knockout (Trp63 flox/floxt ; Pax2-cre) vaginae. Total 12 samples (3 different genotype/tissue groups x 4 independent samples each).

Neurofibromatosis type 1-dependent alterations in mouse microglia function are not cell-intrinsic

Project description:We previously discovered a sex-by-genotype defect in microglia function using a germline heterozygous knockout mouse model of Neurofibromatosis type 1 (Nf1+/- mice), in which only microglia from male Nf1+/- mice exhibited defects in purinergic signaling. Herein, we leveraged an unbiased proteomic approach to demonstrate that male, but not female, heterozygous Nf1+/- microglia exhibit differences in protein expression, which largely reflect pathways involved cytoskeletal organization. In keeping with potential defects in cytoskeletal function, only male Nf1+/- microglia had reduced process arborization and surveillance capacity. Next, to determine whether these microglial defects were cell autonomous or reflected adaptive responses to Nf1 heterozygosity in other cells in the brain, we generated conditional microglia Nf1-mutant knockout mice by intercrossing Nf1flox/flox with Cx3cr1-CreER mice (Nf1flox/wt; Cx3cr1-CreER mice, Nf1MG+/- mice). Surprisingly, neither male nor female Nf1MG+/- mouse microglia had impaired process arborization or surveillance capacity. In contrast, when Nf1 heterozygosity was generated in neurons, astrocytes and oligodendrocytes by intercrossing Nf1flox/flox with hGFAP-Cre mice (Nf1flox/wt; hGFAP-Cre mice, Nf1GFAP+/- mice), the microglia defects found in Nf1+/- mice were recapitulated. Collectively, these data reveal that Nf1+/- sexually dimorphic microglia abnormalities are likely not cell-intrinsic properties, but rather reflect a response to Nf1 heterozygosity in other brain cells.

Heterozygous and Homozygous Knock-Out of USP7 mouse models [mouse_RNA-seq]

Project description:RNAseq analysis of USP7 conditional knock-out (cKO) mice. They were designed to flox exon 6 of USP7 and to allow deletion of exon 6 upon expression of Cre recombinase 27. USP7FL/FL mice were bred with Vav1-Cre mice to obtain USP7FL/wt-Vav1-Cre mice (heterozygote). USP7FL/FL-Vav1-Cre mice (homozygote) were obtained via breeding of heterozygous cKO mice.

The Zinc Finger Transcription Factor Sp9 Is Required for the Development of Striatopallidal Projection Neurons

Project description:Purpose: To assess changes in gene expression profiles from the P0 littermate Sp9Flox/Flox control striatum (including SVZ) and conditional mutant striatum of Drd2-Cre; Sp9Flox/Flox mice. Methods: total RNA was isolated and sequenced from the striatum of the P0 littermate Sp9Flox/Flox control or conditional mutant striatum of Drd2-Cre; Sp9Flox/Flox mice in triplicate using an Illumina high-seq 2500. Raw data was analyzed using TopHat. Genes were considered changed which demonstrated fold-change>=2, and p value <=0.05. Changed genes were then filtered to reveal Sp9 downstream targets which were altered in vivo due to the loss of Sp9 expression. Results: 179 genes were significantly increased and 147 genes were significantly decreased in expression level due to the loss of Sp9 expression. total RNA was isolated and sequenced from the striatum of the P0 littermate Sp9Flox/Flox control or conditional mutant striatum of Drd2-Cre; Sp9Flox/Flox mice in triplicate using an Illumina high-seq 2500.

Expression data from mesodermal Tbx1-knockout otic vesicles at E11.5

Project description:The T-box transcription factor Tbx1 is expressed in the otic vesicle and surrounding periotic mesenchyme during inner ear development. Mesenchymal Tbx1 is essential for inner ear development, with conditional mutants displaying defects in both auditory and vestibular systems. We have previously identified reduced expression of retinoic acid metabolic genes in the periotic mesenchyme of mesoderm conditional Tbx1 mutants, using the T-Cre mouse line, implicating retinoic acid in mesenchymal-epithelial signaling downstream of Tbx1 in the periotic mesenchyme. In order to identify downstream effectors of mesenchymal-epithelial signaling downstream of mesenchymal Tbx1, we have utilized a gene profiling approach comparing embryonic day 11.5 otic vesicle tissue from T-Cre-mediated conditional Tbx1 mutants (Mest-KO) and conditional heterozygous control litter mates (control). E11.5 T-Cre-mediated conditional Tbx1 mutants (Mest-KO) and control (T-Cre conditional Tbx1 heterozygotes) embryos were microdissected to isolate the otic vesicle. Left and right ears from 3 embryos of the same genotype were pooled for each chip.
