Project description:Hippocampus and hypothalamus RNA-sequencing of WFS1-deficient mice [hippocampus]

Project description:Wolfram syndrome is caused by mutations in the WFS1 gene. WFS1 protein dysfunction results in a range of neuroendocrine syndromes and is mostly characterized by juvenile-onset diabetes mellitus and optic atrophy. WFS1 has been shown to participate in membrane trafficking, protein processing and Ca2+ homeostasis in the endoplasmic reticulum. In the present study we aimed to find the transcriptomic changes influenced by Wfs1 in the hypothalamus and hippocampus using RNA-sequencing. We used WFS1-deficient mice as a model system to analyze the changes in transcriptional networks. The number of differentially expressed genes between hypothalami of WFS1-deficient (Wfs1KO) and wild-type (WT) mice was 43 and between hippocampi 311 with False Discovery Rate (FDR) <0.05. In hypothalamus of Wfs1KO mice one of the most upregulated genes was Avpr1a whilst Avpr1b was significantly upregulated in hippocampus. Trpm8 was the most upregulated gene in the hippocampus of Wfs1KO mice. The functional analysis revealed significant enrichment of networks and pathways associated with protein synthesis, cell-to-cell signaling and interaction, molecular transport, metabolic disease and nervous system development and function. In conclusion, the transcriptomic profiles of WFS1-deficient hypothalamus and hippocampus do indicate the activation of degenerative molecular pathways causing the clinical occurrences typical to Wolfram syndrome.

Project description:The hypothalamus is a functionally and cellularly complex tissue controlling many developmental processes, including puberty. While key hormonal aspects of puberty regulation in the hypothalamus are well established, understanding the genes, cell-types, and epigenetic mechanisms underlying and regulating puberty is limited. Here, we performed 3’-UTR-seq on the hypothalamus from both sexes of C57BL/6J mice at 5 ages spanning pubertal transition (postnatal days 12, 22, 27, 32, 37) (4-5 replicates per sex at each age) to examine genome-wide age- and sex-biased trends in gene expression in a cell-type aware manner. Sample collection, RNA extraction, and sequencing was completed using the same protocols and on the same mice as PMID: 3622112 (E-MTAB-9459). QuantSeq 3’mRNA-seq libraries were constructed from total RNA using an automated method with Agilent NGS Workstation. The resulting single-end libraries were sequenced at SickKids TCAG core on the Illumina v4 flow cell with SR50 bp cycles extended to 68 bp. A customized pipeline was developed and used for the analysis of reads obtained (PMID: 36221127 for details). Processed reads were mapped to mouse genome (mm10).

Project description:Wolfram syndrome, an autosomal recessive disorder characterized by juvenile-onset diabetes mellitus and optic atrophy, is caused by mutations in the WFS1 gene. WFS1 encodes an endoplasmic reticulum resident transmembrane protein. The Wfs1-null mice exhibit progressive insulin deficiency and diabetes. The aim of the present study was to describe the insulin secretion and transcriptome of pancreatic islets in WFS1-deficient mice. WFS1-deficient (Wfs1KO) mice had considerably less pancreatic islets than heterozygous (Wfs1HZ) or wild-type (WT) mice. Wfs1KO pancreatic islets secreted less insulin after stimulation with 2 and 10 mM glucose and with tolbutamide solution compared to WT and Wfs1HZ islets, but not after stimulation with 20 mM glucose. Differences in proinsulin amount were not statistically significant although there was a trend that Wfs1KO had an increased level of proinsulin. After stimulation with 2 mM glucose solution the proinsulin/insulin ratio in Wfs1KO was significantly higher than that of WT and Wfs1HZ. RNA-seq from pancreatic islets found melastatin-related transient receptor potential subfamily member 5 protein gene (Trpm5) to be downregulated in WFS1-deficient mice. Functional annotation of RNA sequencing results showed that WFS1 deficiency influenced significantly the pathways related to tissue morphology, endocrine system development and function, molecular transport network. These findings suggest an interactive role of WFS1 and TRPM5 in insulin secretion. 12 samples: three genotypes, 4 individuals in each genotype

Project description:WFS1 gene is coding protein with unknown function but its functional deficiency causes different neuropsychiatric and neuroendocrine syndromes. In the present study we aimed to find the functional networks influenced by the Wfs1 deficiency in the hypothalamus. We performed gene expression profiling (Mouse Gene 1.0 ST Arrays) in Wfs1 deficient mice (ko). Modified t-statistics was used for comparison of groups (wt vs ko). Functional annotation of the alterations in RNA levels was performed with Ingenuity Pathway Analysis. 305 genes were differentially expressed with nominal p-value less than 0.01. FDR adjusted p-values were significant (0.007) only for two genes M-bM-^@M-^S C4b (t=9.66) and Wfs1 (t=-9.03). However, several genes related to the G-protein signalling were very close to the FDR adjusted significance. For instance, Rgs4 (regulator of G-protein signalling 4) was down-regulated (-0.34, t=-5.4) in Wfs1 deficient mice. Changes in Rgs4 and C4B expression were confirmed by QRT-PCR. In humans, Rgs4 is in the locus for bipolar disease (BPD) and its expression is down-regulated in BPD. C4b is the gene related to the neurodegenerative diseases. In conclusion, hypothalamic gene expression profiling indicates alterations in some functionally relevant molecular pathways explaining the clinical syndrome in the Wolfram syndrome patients. 18 samples, two genotypes (wild type and mutant), in 129S6 genetic background
