Project description:Gonadal sex determining (GSD) genes that initiate fetal ovarian and testicular development and differentiation are expressed in the cells of the urogenital ridge that differentiate as somatic support cells (SSCs), i.e., granulosa cells of the ovary and Sertoli cells of the testis. To identify potential new mammalian GSD genes, we analyzed the gene expression differences between XX and XY SSCs cells isolated from the gonads of embryonic day (E) 13 mouse fetuses carrying an EGFP reporter transgene expressed specifically in SSCs. In addition, genome wide expression differences between XX and XY E13 whole gonads were examined. Newly identified differentially expressed transcripts are potential GSD genes involved in unexplained human sex reversal cases. Experiment Overall Design: Two seperate RNA samples were obtained from E13 XX and XY sorted EGFP+ cells, and two seperate RNA samples were obtained from E13 XX and XY pooled gonads. Approximately 20ng of total RNA from each sample was used to generate biotin-labelled cDNA. Approximately 2.5ug biotin labelled cDNA of each sample was used for each Mouse Genome 430v2.0 GeneChip array (Affymetrix). Significantly differentially expressed transcripts were identified using R/maanova. Statistical significance was determined at a false discovery rate value of equal to or less than 1%.

Project description:Here we report that the epigenetic factor Chromodomain Y-like (CDYL) protein is a critical regulator for the initiation and maintenance of activity-dependent intrinsic neuroplasticity. Genome-wide ChIP-sequencing analysis revealed that CDYL regulates multiple neuronal functional pathways including voltage-gated ion channels in mouse brains. We showed that CDYL binds to a regulatory element in the intron region of SCN8A and mainly recruits H3K27me3 activity for transcriptional repression of the gene. Injection of lentivirally-delivered CDYL shRNA to rat hippocampal neurons resulted in augmented Nav1.6-mediated sodium currents, lower neuronal threshold and increased seizure susceptibility, whereas transgenic mice over-expressing CDYL had higher neuronal threshold and were less prone to epileptogenesis. Finally, examination of human brain tissues revealed decreased expression of CDYL and increased expression of SCN8A in the temporal lobe epilepsy group. Together, our findings indicate CDYL is a critical player for experience-dependent gene regulation in controlling intrinsic excitability, which potentially contributes to learning and memory and CNS disorders involving change in activity such as epilepsy.

Experiment Overall Design: Two-color Agilent microarray profiles of 20 individual pairs of e11.5 XY gonads, including 5- C57BL/6J, 5- 129S1/SvImJ, 5- (B6x129S1)F1, and 5- (129S1xB6)F1 samples. Within each strain, samples were collected from multiple litters to account for potential litter biases. All samples were processed following the same protocol.

Project description:We report that the epigenetic factor CDYL is crucial for pain processing. CDYL downstreams in mouse dorsal root ganglia (DRG) are mostly associated with neurological functions, including chemical synaptic transmission, regulation of membrane potential and ion transport. CDYL facilitates H3K27me3 deposition at the Kcnb1 intron region thus silencing Kv2.1 transcription. Loss function of CDYL enhances total Kv and Kv2.1 current density in DRG and knockdown of Kv2.1 reverses the pain-related phenotypes of Cdyl deficiency mice.

Project description:Impaired endometrial receptivity is one of the major causes of recurrent implantation failure (RIF), and the underlying molecular mechanism has not been fully elucidated. We demonstrated that Chromodomain Y like (CDYL) was highly expressed in the endometrium at mid-secretory phase during the normal menstrual cycles. However, the expression of CDYL was down-regulated in the endometrial tissues obtained from women with RIF, consistently with the protein level of LIF, which is the marker of endometrial receptivity. Knockdown of CDYL significantly decreased the cell migration of human endometrial Ishikawa cells and primary endometrial cells. Genomic analyses revealed that CDYL gene silencing resulted in decreased expression of many genes associated with cytoskeleton and migration regulation.

Project description:Background:molecular mechanisms coupling cellular metabolisms with the epigenome in cystic cells remains largely unknown Methods:To investigate the molecular mechanisms underlying the suppression of cyst growth by CDYL overexpression, we generated an engineered ADPKD cell line by stably expressing CDYL with TY1 tag in WT 9-12 human ADPKD cells (CDYL OE). We profiled genome-wide distribution of CDYL through chromatin immunoprecipitation coupled with sequencing (ChIP-seq) analysis in both parental WT 9-12 cells (control) and CDYL OE cells. Genetic overexpression of CDYL reduces histone Kcr. We examined histone Kcr on CDYL-target genes by performing ChIP-seq analyses using antibody recognizing PanKcr and H3K18cr in control and CDYL OE cells. Results: Using integrative cistromic and transcriptomic analyses, CDYL-regulated cyst-associated genes are identified, whose downregulation depends on CDYL-mediated suppression of histone Kcr. Conclusions: Thus, through establishing a metabolic niche via nuclear condensation, CDYL connects metabolic changes to transcriptional response via histone Kcr in ADPKD.
