Project description:The gut microbiome shapes local and systemic immunity. The liver is presumed to be a protected sterile site. As such, a hepatic microbiome has not been examined. Here, we show that the liver hosts a robust microbiome in mice and humans that is distinct from the gut and is enriched in Proteobacteria. It undergoes dynamic alterations with age and is influenced by the environment and host physiology. Fecal microbial transfer experiments revealed that the liver microbiome is populated from the gut in a highly selective manner. Hepatic immunity is dependent on the microbiome, specifically Bacteroidetes species. Targeting Bacteroidetes with oral antibiotics reduced the hepatic immune cell infiltrate by ~90%, prevented APC maturation, and mitigated adaptive immunity. Mechanistically, presentation of Bacteroidetes-derived glycosphingolipids to NKT cells promotes CCL5 signaling, which drives hepatic leukocyte expansion and maturation. Collectively, we reveal a microbial – glycosphingolipid – NKT – CCL5 axis that underlies hepatic immunity.

Project description:Microbiome dysregulation affects the estrogen metabolism (estrobolome) profile which in turns affects the immunological response. Estrogen hormone is an essential hormone that regulates the sexual activity in females as well as immune response in both sexes. Endometriosis is one of complicated disorder influnce the fertility of females due to escape of endometrial tissue into peritoneal cavity where the immunotoxicity will be undertaken. This study designed to investigate if there is any correlation between the microbiome dyregulation with the severity of endometriosis outcomes.

Project description:Comparison of mRNA expression profiles in W12 Series 1 cervical ectokeratinocytes at passage number 22 versus 19 (during which time the cells gain an invasive phenotype) As these cells demonstrate gain of chromosome 5p during this time, mRNA expression profiling data interrogated for over-expressed genes on 5p that may be important in cervical neoplastic progression.

Project description:The Estrogen Receptor beta (ERβ) has an essential role in endometriosis progression. However, the molecular mechanism of how ERβ drives endometriosis progression is not elucidated, yet. To define the role of genomic ERβ in endometriosis progression, we have employed whole-genome microarray expression profiling as a discovery platform to identify ERβ-regulated transcriptome in endometriotic tissues. To get this transcriptome, we applied endometrium specific ERβ overexpression (ERBOE) mouse model by crossing mouse having a pCAG promoter-loxPSTOPloxP-ERβ cassette with PRCre knockin mice that Cre recombinase cDNA was inserted into exon 1 of PR gene. Endometriosis was surgically induced in ERBOE mice and PRCre mice as the control by transplantation of uterine tissues. The ectopic lesions and eutopic endometrium were harvested at the estrus cycle in 4th weeks after endometriosis induction.

Project description:To explore the circRNA expression profiles during the development and progression of cervical cancer, we performed RNA sequencing analysis with ribosomal RNA-depleted in HPV negative normal cervical epithelium, HPV16 positive normal cervical epithelium, HPV16 positive high-grade squamous intraepithelial lesion (HSIL), and HPV16 positive cervical squamous cell carcinoma tissues,6 cases in each group.Totally 66868 circRNAs were identified (Back-spliced junctions reads≥1)

Project description:Gut-brain connections monitor the intestinal tissue and its microbial and dietary content1, regulating both intestinal physiological functions such as nutrient absorption and motility2,3, and brain–wired feeding behaviour2. It is therefore plausible that circuits exist to detect gut microbes and relay this information to central nervous system (CNS) areas that, in turn, regulate gut physiology4. We characterized the influence of the microbiota on enteric–associated neurons (EAN) by combining gnotobiotic mouse models with transcriptomics, circuit–tracing methods, and functional manipulation. We found that the gut microbiome modulates gut–extrinsic sympathetic neurons; while microbiota depletion led to increased cFos expression, colonization of germ-free mice with short-chain fatty acid–producing bacteria suppressed cFos expression in the gut sympathetic ganglia. Chemogenetic manipulations, translational profiling, and anterograde tracing identified a subset of distal intestine-projecting vagal neurons positioned to play an afferent role in microbiota–mediated modulation of gut sympathetic neurons. Retrograde polysynaptic neuronal tracing from the intestinal wall identified brainstem sensory nuclei activated during microbial depletion, as well as efferent sympathetic premotor glutamatergic neurons that regulate gastrointestinal transit. These results reveal microbiota–dependent control of gut extrinsic sympathetic activation through a gut-brain circuit.

Project description:The association between endometriosis, genomic copy number variant polymorphisms and differential gene expression is still unclear. The rationale of this study was to identify regions of copy number change in familial endometriosis, which could contain genes that may be involved with the susceptibility and progression of this disease.

Project description:Endometriosis is associated with aberrant gene expression in the eutopic endometrium of women with disease. To determine if the development of endometriotic lesions directly impacts eutopic endometrial gene expression, we sequentially analyzed the eutopic endometrium across the time course of disease progression in a baboon model of induced disease. Endometriosis was induced in baboons by intraperitoneal inoculation of autologous menstrual endometrium. Eutopic endometria were collected at 9-11 days postovulation) in five time points: 1, 3, 6-7, 10-12, and 15-16 months after disease induction and compared with tissue from disease-free baboons. We used microarrays to identify differentially expressed genes between time points. Sequential analysis of the same animals during disease progression demonstrated an early disease insult and a transitory dominance of an estrogenic phenotype. However, as the disease progressed, a progesterone-resistant phenotype became evident. Endometriosis was experimentally induced in Papio anubis female baboons (n = 4) by intraperitoneal inoculation with menstrual endometrium on two consecutive menstrual cycles. Baboons with spontaneous endometriosis (n = 2) were also included in this study with an unknown duration of disease. Control endometrium was similarly harvested from animals (n = 4) with no previous surgeries and with no visible disease. The progression of disease was monitored in each animal by consecutive laparoscopies and video recording at 1 (n = 2), 3 (n = 4), 6-7 (n = 4), 10-12, (n = 4), and 15-16 (n = 3) months after inoculation during a window of 9-11 days postovulation. Eutopic endometrial tissues were harvested and were snap frozen in liquid nitrogen for RNA extraction. Additionally, menstrual endometrium was harvested on Days 1-2 of menses using a Unimar Pipelle (Cooper Surgical Inc., Shelton, CT) immediately prior to laparoscopy. Blood samples were collected daily from days 7 through 16 postmenstruation of menstrual cycles.
