Project description:Background: Idiopathic Chronic Diarrhea (ICD) is a common cause of morbidity and mortality among juvenile rhesus macaques. Characterized by chronic inflammation of the colon and repeated bouts of diarrhea, ICD is largely unresponsive to medical interventions including corticosteroid, antiparasitic and antibiotic treatments. Although ICD is accompanied by large disruptions in the composition of the commensal gut microbiome, no single pathogen has been concretely identified as responsible for the onset and continuation of the disease. Results: Fecal samples were collected from twelve ICD-diagnosed macaques and twelve age and sex-matched controls. RNA was extracted for metatranscriptomic analysis of species and activity within the gut microbiome. Using SAMSA2, these samples were contrasted to identify shifts both in overall organism activity and functional activity. Bacterial, fungal, archaeal, protozoan, and macaque (host) transcripts were simultaneously assessed. ICD-afflicted animals were characterized by increased activity of known bacterial pathogens and by decreased activity of archaeal methanogens. Interestingly, known fungal opportunists were not increased in ICD, nor were the usual enteric protozoans, although Trichomonas activity is up-regualted. Known mucin degrading organisms and mucin-degrading enzymes were up-regulated in the fecal microbiomes of ICD-afflicted animals. Assessment of colon sections using immunohistochemistry confirmed differential mucin composition between healthy control and ICD animals. Finally, assessment of host-derived transcripts confirms colonic inflammation and suggests that the lumen is infiltrated by granulocytes. Conclusions: The simultaneous profiling of bacterial, fungal, archaeal, protozoan, and macaque transcripts from stool samples suggests that ICD of rhesus macaques is associated with increased pathogen activity and altered mucin degradation.

Project description:Spotted 10uM of phenylacetylglutamine on a metal surface and used wooden cotton swabs to wipe the area after 45min. Extracted the recovery in Eppendorfs through centrifugation. Dried and resuspended the samples in 50% methanol spiked with sulphadimethoxine for LC-MS analysis. Spotted samples were wiped for 1min vs 5sec, once vs twice, and the cotton swab rinsed in some cases. Data file names in the master sequence and Skyline report are labeled as "car-XX.raw", but in all cases the standard is actually phenylacetylglutamine.

Project description:Irritant contact dermatitis (ICD) is a non-immunological, cutaneous inflammatory response to a variety of triggers that requires no sensitization and accounts for up to 80% of occupational dermatitis cases. Numerous inflammatory cytokines play critical roles in the mechanism and severity of ICD, one being interleukin-6 (IL-6). Therefore, to investigate the influence of this pleotropic cytokine transcriptome analysis (MiSeq) was employed examining irritant-exposed and control skin samples from C57 and IL-6KO mice to gain a better understanding of the immunological mediators of ICD and what role IL-6 plays. Overall, this study offers new insight into the pathogenesis of ICD, indicates new mediators/markers that may influence the variability of responses to irritants and potential targets for therapeutic manipulation.

Project description:Genome wide DNA methylation profiling of blood samples collected from patients after diagnosis with hepatocellular carcinoma (HCC) (cases) vs. blood samples collected from healthy individuals without family history of cancer (controls). The Illumina Infinium 450K Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 450,000 CpGs in human samples corresponding to cases (post-diagnostic HCC) and controls. Samples included 24 cases and 24 controls. Cases were matched with controls on gender, age, ethnicity, hepatitis C infection, and diabetes. The presence or absence of HCC in our study was determined based on the AASLD criteria.
