Project description:Purpose: Zinc Finger MIZ-Type Containing 1 (Zmiz1) is a member of the PIAS family of protein and function as a transcriptional coactivator of Notch, Androgen Receptor (AR), p53, Estrogen Receptor (ER), and Smad3/4 . Despite Zmiz1 mutations association with neurodevelopmental disorders such as ASD, ADHD, and intellectual disability, its role in physiological and pathological neurodevelopment is significantly unknown. Here, we use murine model to knockout Zmiz1 using Emx1Cre and performed RNA sequencing on P7 cortex to profile transcriptional changes upon Zmiz1 deletion. Timed pregnancy was carried out. Mice was euthanized using CO2 and embryos brain were extracted at E15.5. Cortex was dissected and dissociated into single cell suspension using Neural Tissue Dissociation Kit (P) (Miltenyi Biotec, 130-092-628) following manufacture instruction. Intermediate progenitors were magnetically selected and isolated using Anti-Prominin-1 MicroBeads, mouse (Miltenyi Biotec, 130-092-333). Total RNA was extracted from wildtype and Zmiz1-KO samples. RNA concentration and RNA integrity number were determined. RNA library was prepared, quantified, and verified using TruSeq RNA Library Prep Kit v2, Qubit dsDNA High Sensitivity Assay kit and Bioanalyzer DNA1000 assay kit respectively. Verified samples were sequenced using the NextSeq1000/2000 P2 Reagents (200 Cycles) v3 on a Nextseq1000/2000. RNA-seq data analysis was performed using illumina BaseSpace Sequence Hub. Briefly, sequenced reads were aligned to mouse (mm10) reference genome with RNA-Seq alignment tool (STAR aligner) and differentially expressed genes (DEG) were determined using the RNA-Seq Differential Expression tool (version 1.0.1). Results: We found 114 differentially expressed genes of which 35 genes were upregulated while 69 genes were downregulated. Downregulated genes were enriched in biological processes such as forebrain deveopment, axon development, neuron differentiation etc. Conclusions: We assessed P7 cortex specific transcriptional profile changes which are potentially regulated by Zmiz1.
Project description:To unravel the effect of increased extracellular serotonin levels on brain development, RNA-seq was performed in the medial prefrontal cortex of serotonin transporter knockout and wildtype rats at five time points from early life to adulthood (postnatal day (PND) 8, 14, 21, 35 and 70). Differential expression of protein-coding genes was analyzed and we demonstrate that a lack of functional 5-HTT especially affects gene expression in early postnatal life (PND8).
Project description:To investigate the gene expression difference between knee joint cartilaginous tissues of conditionally knockout Hbb or wildtype postnatal day 6 mice.
Project description:To examine how miRNAs differ between medial entorhinal cortex layers during postnatal development, we analyzed the miRNA expression in layer II and the deep layers (III-VI) at postnatal ages P2, P9, P23 and P45 in wildtype Long Evans rats. The expression of the two most significantly differentially expressed miRNAs were validated by in situ hybridization.
Project description:To investigate the role of Gm1142 protein in mouse reproduction, We collected Gm1142-/-, Gm1142-/- Gm4779-/- and normal wildtype mouse testes on postnatal day 7 (P7) for RNA sequencing.

Project description:DNA methylation profiling of Prefrontal Cortex of male rats at postnatal day 62 whose mothers were exposed to restraint stress from gestation day 14 until delivery The groups consist of 1. Control rats (Ctrl) 2. Prenatally stressed rats (PNS)
Project description:Transgenic mice expressing a truncated form of Zmiz1 in the skin develop spontaneous keratoacanthomas. In this experiment, a Cre-inducible transgene expressing a truncated form of Zmiz1 was introduced into mice. Activation of the transgene in these mice was achieved by breeding to K14-Cre transgenic animals. Double transgenic mice formed spontaenous keratoacanthomas with short latency. In this experiment, we generated gene expression profiles for five Zmiz1-induced keratoacanthomas and six normal skin samples.
