Project description:Gallstone disease is a worldwide common disease. However, the knowledges concerning the gallbladder in the pathogenesis of cholesterol gallstone formation remains limited. In this study, using single-cell RNA sequencing (scRNA-seq), we showed cellular heterogeneity and transcriptomic dynamics in murine gallbladder cells during the process of lithogenesis. Our results indicated gallbladder wall were subjected to remodeling during the process of lithogenesis. The major molecular events happened included proliferation of epithelial cells, infiltration of immune-cells, activation of angionesis and extracellular matrix modulation. Furthermore, we observed partial reversal of gallbladder cell transcriptomes by ursodeoxycholic acid treatment. This work thus provides novel and integral knowledges on the cellular changes during lithogenesis, which is of great significance to the understanding of pathogenesis and treatment of cholesterol gallstone.

Project description:<p>Gallstones are crystalline deposits in the gallbladder that are traditionally classified as cholesterol, pigment or mixed stones based on their composition. Microbiota and host metabolism variances among the different types of gallstones remain largely unclear. Here, the bile and gallstone microbial species spectra of 29 subjects with gallstone disease (GSD, 24 cholesterol and 5 pigment) were revealed by type IIB restriction site-associated DNA microbiome sequencing (2bRAD-M). Among them (21 subjects: 18 cholesterol and 3 pigment), plasma samples were subjected to liquid chromatography-mass spectrometry (LC-MS) untargeted metabolomics. The microbiome yielded 896 species comprising 882 bacteria, 13 fungi, and 1 archaeon. Microbial profiling revealed significant enrichment of Cutibacterium acnes and Microbacterium sp005774735 in gallstone and Agrobacterium pusense and Enterovirga sp013044135 in the bile of cholesterol GSD subjects. The metabolome revealed 2296 metabolites, in which malvidin 3-(6''-malonylglucoside), 2-Methylpropyl glucosinolate and ergothioneine were markedly enriched in cholesterol GSD subjects. Metabolite set enrichment analysis (MSEA) demonstrated enriched bile acids biosynthesis in individuals with cholesterol GSD. Overall, the multi-omics analysis revealed that microbiota and host metabolism interaction perturbations differ depending on the disease type. Perturbed gallstone type-related microbiota may contribute to unbalanced bile acids metabolism in the gallbladder and host, representing a potential early diagnostic marker and therapeutic target for GSD.</p>

Project description:Gallstone disease is a major contributor to health care costs in the United States. Approximately 12 % of the U.S. population has gallstones. As a result, more than 700,000 cholecystectomies are performed in this country each year. Many of these patients are obese and have a positive family history; but surprisingly, little is known about the link between obesity, genetics and gallstone formation. Obese individuals have been shown to have supersaturated bile, larger gallbladder fasting volumes and impaired gallbladder emptying. We have recently demonstrated that leptin plays a role in gallbladder motility. In an effort to understand the genetic basis for these observations, we tested the hypothesis that leptin would alter gallbladder gene expression. Methods: Affymetrix oligonucleotide microarrays 430 2.0 were used to compare gallbladder gene expression profiles from 12 week old control saline-treated leptin-deficient (Lep ob) and from leptin-treated Lep ob female mice. Analyses were performed on pooled RNA (n=4) from the gallbladders of 12 saline-treated Lep ob mice and from 12 Lep ob mice which were administered daily IP 5 ug/g of recombinant murine leptin for 4 weeks. Resulting data were analyzed utilizing Gene Chip Operating Software or MAS 5.0. Results: Of the genes analyzed 314 were upregulated and 108 were downregulated by leptin administration. Numerous genes related to gallstone pathogenesis, gallbladder absorption/secretion, inflammatory cytokines, and insulin resistance were altered by leptin. Keywords: comparitive response to leptin

Project description:Following a large-scale genome-wide association study of gallstone disease, we performed RNA sequencing from tissues of four human gallbladders (3 healthy controls and 1 case with chronic gallstones) and one liver sample from the gallstone case. We aimed to determine the expression patterns of gallstone disease-associated genes in gallbladder and liver, two organs of interest in disease etiology.

Experiment Overall Design: Female B6.V-lepob obese mice (n=24) aged 7 weeks were obtained from The Jackson Laboratory (Bar Harbor, ME). Upon arrival, mice were placed on a standard chow diet and were allowed to acclimate for 1 week before starting the experiment. For leptin treatments, mice received daily intraperitoneal injections of either recombinant mouse leptin (R&D Systems, Minneapolis, MN) (n=12) at a dose of 5 µg/g body weight or with saline as a control (n=12) for 4 weeks. At 12 weeks of age, mice were fasted overnight with free access to water. The following morning the mice underwent cholecystectomy. Three gallbladders were pooled to create 4 pools in each treatment and total RNA was isolated. Affymetrix murine 430 2.0 arrays were utilized to examine altered gallbladder gene expression as a result of leptin administration. The resulting data was analyzed utlizing Gene Chip Operating Software or MAS 5.0.

Project description:Gene expression throughout the reproductive process in rice (Oryza sativa) beginning with primordia development through pollination/fertilization to zygote formation was analyzed. We analyzed 25 stages/organs of rice reproductive development including early microsporogenesis stages with 57,381 probe sets, and identified around 26,000 expressed probe sets in each stage. Fine dissection of 25 reproductive stages/organs combined with detailed microarray profiling revealed dramatic, coordinated and finely tuned changes in gene expression. Decrease of expressed genes in the pollen maturation process was observed in a similar way with Arabidopsis and maize. An almost equal number of ab initio predicted genes and cloned genes appeared or disappeared coordinated with developmental stage progression. A large number of organ-/stage-specific genes were identified; notably 2,593 probe sets for developing anther, including 932 probe sets corresponding to ab initio predicted genes. Analysis of cell cycle-related genes revealed that several CDKs, cyclins and components of SCF E3 ubiquitin ligase complexes were expressed specifically in reproductive organs. Cell wall biosynthesis or degradation protein genes and transcription factor genes expressed specifically in reproductive stages were also newly identified. Rice genes homologous to reproduction-related genes in other plants showed expression profiles both consistent and inconsistent with their predicted functions. The rice reproductive expression atlas is likely to be the deepest and most comprehensive dataset available, indispensable for unraveling functions of many specific genes in plant reproductive processes that have not yet been thoroughly analyzed. This SuperSeries is composed of the following subset Series: GSE13988: Rice expression atlas (1): Anther development GSE14298: Rice expression atlas (2): Pollination - Fertilization GSE14299: Rice expression atlas (3): Early embryogenesis GSE14300: Rice expression atlas (4): Vegetative tissues GSE14301: Rice expression atlas (5): Anther development (Agilent data) Refer to individual Series

Project description:We determined the global microRNA expression profiles of primary human gallbladder cells and genetically reprogrammed human gallbladder cells and compared with pancreatic beta cells to ascertain the degree of cellular transdifferentatiation of insulin-producing human gallbladder cells to become beta-like cells. First, we cultured patient-derived gallbladder cells and then we transduced these with beta cell transcription factors to reprogram gallbladder cells to become beta-like cells. We used a pan-islet surface monoclonal antibody to enrich for insulin-producing reprogrammed human gallbladder cells using FACS.
