Project description:MicroRNAs negatively regulate gene expression and may serve as biomarkers for human cardiomyopathy. In the domestic cat, hypertrophic cardiomyopathy (HCM) represents the most common primary cardiomyopathy. In humans, the etiology of HCM is linked to mutations in genes of contractile muscle proteins, while in cats a clear proof for causal mutations is missing. The etiology of feline HCM is uncertain. Diagnosis is made by heart ultrasound examination and measuring the serum level of N-terminal pro B-type natriuretic peptide. The purpose of this study was to investigate whether microRNA profiles in the serum of cats with HCM are different from the profiles of healthy cats and whether specific miRNAs can be detected to serve as potential biomarkers for feline HCM or may help in understanding the etiology of this disease Blood was drawn from two groups of cats: 12 healthy cats and 11 cats suffering from hypertrophic cardiomyopathy. After clotting, samples were centrifuged and total mRNA was extracted from serum. These 23 serum samples were analyzed and the groups were compared

Project description:Background: The horn fly, Haematobia irritans (L.), is an obligate blood-feeding parasite of cattle and control of this pest is a continuing problem in the United States and other parts of the world. Worldwide annual economic losses attributable to this pest surpass $1 billion. The fly is becoming resistant to pesticides and new control technologies are needed by cattle producers. Results: Dominant conditional lethal gene systems are being investigated as population control technologies against agricultural insect pests. One of the critical components of these systems is a highly expressed female-specific gene promoter which can be used to drive expression of a lethality-inducing gene. To identify candidate genes to supply this gene promoter, microarrays were designed from a recently developed horn fly EST database and probed to identify female-specific and larval-specific differential gene expression. Analysis of dyeswap experiments found 432 and 417 transcripts which were over- and under-expressed in adult female flies, respectively, compared to adult male flies. Additionally, 419 and 871 transcripts were over- and under-expressed in first instar larvae compared to adult flies. Three transcripts were identified which were over-expressed in adult females flies compared to adult males and which also were over-expressed in the first instar larval lifestage compared to adult flies. Conclusion: We have identified 3 strong candidates for further evaluation as a gene promoter source for the development of a female-specific conditional lethality system in the horn fly. One of these candidates, the putative nanos orthologue, has a high female-to-male expression ratio, has a moderate expression level in first instar larvae, and has been well characterized in D. melanogaster. Further investigations leading from this microarray analysis will include transformation of the horn fly and evaluation of the female conditional lethal system components for applicability to the specific biological parameters of natural populations of the horn fly.

Project description:A soy diet worsens the progression of an inherited form of hypertrophic cardiomyopathy (HCM) in male mice when compared to casein-fed mice. Females are largely resistant to this diet effect and better preserve cardiac function. We hypothesized that the abundant phytoestrogens found in soy are mainly responsible for this diet-dependent phenotype. Indeed, feeding male mice a phytoestrogen-supplemented casein-based diet can recapitulate the negative outcome seen when male mice are fed a standard soy-based diet. To gain mechanistic insights into disease pathogenesis, we used Affymetrix microarrays to profile gene expression in left ventricular tissue from 2 month old HCM male and female mice as well as wild-type littermate controls. These mice were fed a phytoestrogen (genistein + daidzein)-supplemented casein-based diet. We identified a number of molecular pathways that could explain both the male and female phenotypes. Hearts from male and female wild-type or HCM C57BL/6 mice fed a phytoestrogen-supplemented (genistein and daidzein mix) casein-based diet were excised at 2 months of age. Total RNA was extracted from left ventricles. Biotin-labeled amplified RNA was hybridized to Affymetrix Mouse Genome 430 2.0 microarrays.

Project description:We present a comparative analysis of sex-specific tegument proteins of paired or virgin Schistosoma mansoni. By apply a new and highly sensitive workflow, detection of even low abundance proteins from the worm was achieved Therefore, a streptavidin-biotin affinity purification technique in combination with single pot solid-phase enhanced sample preparation was established for subsequent LC-MS/MS analysis. We were able to identify 1519 tegument proteins for male and female as to virgin and paired worms. Sex-specific proteins were screened, present in both virgin and paired adult schistosomes to reduce the impact of mating. Bioinformatic analysis revealed an involvement of female-specific tegument proteins in signaling pathways of cellular processes and antioxidant mechanisms. Male-specific proteins were found to be enriched in processes linked to phosphorylation and signal transduction. This suggests a task sharing between the sexes that might be necessary for survival in the host. Our datasets provide a basis for further studies to understand and ultimately decipher the strategies of the two worm sexes to evade the immune system.

Keywords: adult male vs female hornfly gene expression In short, RNA from female horn flies was labeled and hybridized against labeled RNA from male horn flies in a dyeswap design. Similarly, RNA from first instar larvae was labeled and hybridized against labeled a 50:50 mix of RNA from adult male and female flies. All labeling, hybridization and washing procedures were performed according to respective manufacturer protocols. For each sample, 10 ïg of total RNA and 50-fold dilution of Agilent two color spike-in control RNA kit (Agilent Technologies Inc.) were labeled with either CyDye3-dCTP or CyDye5-dCTP (Amersham Biosciences, Piscataway, NJ) using the LabelStar kit (Qiagen Inc., Valencia, CA) and oligo-dT and Random nonamers (Sigma-Aldrich Inc., St. Louis, MO). Labeled cDNA was hybridized to the Agilent microarrays using the Gene Expression Hybridization kit (Agilent Technologies Inc.) following manufacturerâs protocols. Arrays were washed with Gene Expression Wash Buffer kit (Agilent Technologies Inc.) A total of 8 arrays, including a dye swap for each RNA replicate (4 biological replicates), were analyzed to obtain genes that were consistently regulated while limiting false discover rate (FDR) below 2.5% [26].
