Project description:Food composition of diets strongly determines the risk of experiencing inflammation related metabolic or cardiovascular disease. We aimed to determine the extent of inheritance of inflammatory responses to isocaloric changes in food composition as a prerequisite of personalized dietary recommendations in human twins. 34 monozygotic and 12 dizygotic healthy pairs of twins recruited from a twin register (HealthTwiSt, Berlin, Germany) or by public advertisements completed the study. All participants received a low fat diet (55% carbohydrate, 30% fat, 15% protein) for 6 weeks (CID1=LF thereafter) followed by 6 weeks of a high fat diet (40% carbohydrate, 45% fat, 15% protein) (CID2=HF1 after 1 week, and CID3=HF6 after 6 weeks of high fat diet). Both diets were isocloric. A physical examination, anthropometry (DEXA scan), and medical history were obtained and 12h fasted blood was collected at 8:00 a.m. on study days. Resting energy expenditure (indirect calorimetry) and physical activity level (PAL) was assessed by questionnaire and dietary food records for five days were completed before and during the study. Fasting blood levels of cytokines, chemokines and adipokines were determined by ELISA. The participants were instructed, trained and accompanied by an experienced nutritionist. Individual energy requirements were calculated based on participants REE and PAL. Participants received a list of 94 foods items and individual daily meal plans on how to exchange and combine these foods and energy intake was adjusted according to body weight if needed. Seven days before the LF, HF1 and HF6 examination days 70 percent of the food was provided to ensure standardized dietary patterns for all participants. A biopsy of periumbilical abdominal subcutaneous adipose tissue was performed on each CID for gene expression analysis.

Project description:This study describes a comparison of global proteome expression in small intestinal tissue collected from celiac disease patients at different stages of disease. We have analyzed sections from FFPE biopsy blocks and identified more than 4500 protein without sample pre-fractionation. We have compared protein expression in two sample cohorts that were chosen retrospectively from patients participating in research protocols at our facility. First we compared biopsies from 10 patients collected at the time of diagnoses (untreated CD) with biopsies collected 1 year later following gluten free diet (treated CD). We observed overall good agreement between differential expression of proteins and histological changes that occur in the intestine. We identified biological pathways that are known to operate in the disease lesion. We also observed a strong signal for neutrophil infiltration. By use of a dedicated immunoglobulin variable gene family database we found that differential expression of IGHV5-51 distinguished our untreated from treated CD patients. We also compared protein expression in 4 treated CD patients that developed histological changes in the small intestine in response to a 3 day gluten challenge. Although these patients develop an intestinal lesion resembling the lesion observed in untreated patients, we observed differential expression of proteins involved in acute tissue remodeling that were not seen when we compared UCD to TCD samples. Our study presents a proof-of-concept to demonstrate that analysis of material from FFPE tissue block material can provide a comprehensive overview of many disease processes that occur in the celiac small intestine. Changes in protein expression will reveal information on disease state that may not be observed by histological evaluation

Project description:Untargeted proteomics based precise diagnosis and typing of amyloid deposits are crucial for guiding patient management. However, it may not be suitable for early-stage renal amyloidosis with minor damages. Here, we aimed to develop parallel reaction monitoring (PRM)-based targeted proteomics to achieve high sensitivity and specificity in identifying early-stage renal immunoglobulin-derived amyloidosis.This study demonstrates that the utility of these prioritized peptides in PRM-based targeted proteomics ensure highly sensitive and reliable for identifying early-stage renal amyloidosis. Owing to the development and clinical application of this method, rapid acceleration of the early diagnosis, and typing of renal amyloidosis is expected.

Project description:Eosinophlic esophagitis (EoE) is increasely recognized as an antigen-drived disorder. The goal of this study is to reveal the gene expression changes in EoE before and after a successful glucocorticoid steroid treatment. We used microarrays to identify distinct genes involving the pathophysiology of EoE. Esophageal mRNA from the epithelial layers of 5 paired paraffin-embedded biopsies before and after treatment with glucocorticosteroids were harvested and profiled using Affymetrix Human Gene 1.0 ST array to generate differentially regulated mRNA transcripts.

Project description:Eosinophlic esophagitis (EoE) is increasely recognized as an antigen-drived disorder. The goal of this study is to reveal the miRNA expression changes in EoE before and after a successful glucocorticoid steroid treatment. Total RNA was extracted from the esophageal epithelial layers of 5 paired paraffin-embedded biopsies before and after treatment with glucocorticosteroids using RecoverAll Total Nucleic Acid Extraction Kit for FFPE tissues (Ambion, Austin, TX). Five nanograms of total RNA was reverse-transcribed using the Taqman MicroRNA Reverse Transcription Kit and the Megaplex RT primer Human Pool A (Applied Biosystems). The reverse-transcribed cDNA was then pre-amplified in 12 cycles of PCR using Taqman PreAmp Master Mix and the Megaplex PreAmp primers, Human Pool A (Applied Biosystems). The cDNA’s were then diluted and loaded on to a Taqman Human miRNA Array card A (Platform GPL9731 ; Applied Biosystems), which contains probes for 377 distinct miRNAs. The Array cards were run on an ABI HT7900 qPCR instrument. Ct values were obtained for all miRNAs represented on the cards and fold changes in expression were calculated using the delta delta Ct (ddCt) method.

Project description:Purpose: evaluate if different proestrus-estrus concentrations of estradiol (E2) and metestrus progesterone (P4) concentrations specifically regulate oviductal gene expression. Methods: ampulla and isthmus samples of animals whit a large pre-ovulatory follicle and a large CL (LF/LCL) and animals whit a small pre-ovulatory follicle and a small CL (SF/SCL) were collected after slaughter at day four of the estrous cycle. Total RNA was extracted and RNA sequencing was performed using the Illumina HiScanSeq (ampulla samples) and the Illumina HiSeq 2500 (isthmus samples) platforms. Results: After using HTSeq-count, approximately ~60% of the total reads uniquely mapped to the UMD 3.1 reference genome. In the ampulla samples, a total of 692 genes showed differential expression, of which 325 and 367 were up-regulated in the LF-LCL and SF-SCL samples, respectively. In the isthmus samples, a total of 590 genes showed differential expression, of which 274 and 316 were up-regulated in the isthmus of LF/LCL and SF/SCL samples, respectively. Conclusions: Our study represents the first detailed analysis of oviduct transcriptomes, generated by RNA-seq technology. Differential global gene expression profiles identified indicate that the biology of the bovine oviductal tissue is modulated by the periovulatory endocrine milieu. The LF-LCL group transcriptome may potentially reveal molecules associated with higher fertility. Oviductal mRNA profiles of cows whit different endocrine milleus were generated by next generation sequencing.

Project description:Purpouse: Aims of this study were (1) to characterize the endometrial transcriptome, (2) to identify functional pathways, and (3) to molecularly characterize selected pathways overrepresented in the endometrium of day 7 post-ovulation induction of cows treated to ovulate larger versus smaller follicles Methods: Seventy-four multiparous, nonlactating, presynchronized Nelore cows received a progesterone-releasing device and estradiol benzoate on Day–10 (D?10). Animals received cloprostenol (large follicle-large CL group; LF-LCL; N = 35) or not (small follicle-small CL group; SF-SCL; N = 39) on D?10. Progesterone devices were withdrawn and cloprostenol administered 42 to 54 hours (LF-LCL) or 30 to 36 hours (SF-SCL) before GnRH treatment (D0). Tissues were collected at slaughter on D7. Transcriptional profiling of the endometrial tissue was performed by RNA-seq and protein markers for proliferation and apoptosis were identified by immunohistochemistry. Results: Functional enrichment data indicated that LF-LCL endometrium expressed greater abundance of genes associated with biosynthetic and metabolic processes, whereas SF-SCL endometrium .gene expression profile was biased towards cell proliferation. Extracellular matrix-related genes were also upregulated in the SF-SCL endometrium suggesting reorganization of the ECM towards a proliferation permissive phenotype. Immunohistochemistry data confirmed the greater proliferative activity observed in SF-SCL endometrium I comparison to LF-LCL counterparts, and indicated a time-related transition within experimental group. In conclusion, the periovulatory endocrine milieu regulates bovine endometrial gene expression. Furthermore, timing and amplitude of ovarian steroid secretion pattern seem to determine the transition from a proliferation permissive to a biosynthetic and metabolically active endometrial phenotype, which may be associated with the preparation of an optimally receptive uterine environment. Conclusion: the periovulatory endocrine milieu affected D7 endometrial molecular signature. Main pathways affected were related to cell proliferation, ECM composition and remodeling, biosynthetic and metabolic processes. Reported data further suggest that the endometrial tissue from LF-LCL cows experienced an early proliferative phase (D4), whereas the SF-SCL endometrium, exposed to a distinct periovulatory endocrine environment, expressed a delayed onset of the proliferative activity (D7). endometrial mRNA profiles of endocrine manipulated cows were generated by deep sequencing using Illumina HiScanSQ platform
