Project description:The eccrine sweat gland is an exocrine gland that is involved in the secretion of sweat for control of temperature. Malfunction of the sweat glands can result in disorders such as miliaria, hyperhidrosis and bromhidrosis. In addition, inadequate reabsorption of salt from sweat is a major feature of cystic fibrosis. Understanding the transcriptome and proteome of sweat glands is important for understanding the physiology and the role in disease. However, no systematic transcriptome or proteome analysis of sweat glands has yet been reported. To this end, we isolated eccrine sweat glands by microdissecting them from human skin and performed both RNA-seq and proteome analysis. In total, ~138,000 transcripts and ~6,100 proteins were identified. The proteome data of eccrine sweat gland showed enrichment of proteins involved in secretion, reabsorption, and wound healing while the transcriptome data did not show any enrichment for a specific pathway. Importantly, protein level identification of TRPV4 in eccrine sweat gland establishes its importance in re-epithelialization of partial-thickness wound and prevention of dehydration. Furthermore, this study enabled us to identify2 missing proteins. Integration of RNA-seq and proteomic data allowed us to identify 7 peptides from 5 novel genes. Most of the novel proteins were from short open reading frames (sORFs) suggesting that many sORFs still remain to be annotated in the human genome. The peptides mapping to the missing or novel proteins were validated by analyzing synthetic peptides. This study provides the first integrated analysis of the transcriptome and proteome of the human eccrine sweat gland and should become an invaluable resource to biomedical research community for studying sweat glands in physiology and disease.

Project description:Biological processes are optimized by circadian and circannual biological timing systems. In vertebrates, the pineal gland plays an essential role in these systems by converting time into a hormonal signal, melatonin; in all vertebrates, circulating melatonin is elevated at night, independent of lifestyle. We have analyzed the rat pineal transcriptome at mid-day and mid-night to identify genes that exhibit night/day changes in expression. We have also used these data to characterize the non-rhythmic features of the transcriptome that set the pineal gland apart from other tissues by comparing them to the median expression in other rat tissues as found in the Genomics Institute of the Novartis Research Foundation (GNF), Entrez Gene Expression Omnibus (GEO) dataset GDS589.

Project description:We have developed an oligoGEArray with 434 genes from Ae. aegypti salivary gland. OligoGEArray was customized with the salivary gland genes chosen from the transcriptome source published by Ribeiro et al (2007). Oligonucleotides (60bp) were designed and array were manufactured by SABiosciences. Using this OligoGEArray, we analyzed the differential expression of salivary trancritptome upon blood feeding. Salivary glands were dissected from 1, 3, 24 and 48 hours post fed (hpf) and unfed Ae. aegypti. Total RNA were extracted and the differential expression of transcriptome were analysed. Quantitative Real-Time PCR was performed on selected genes to validate the OligoGEArray data.

Project description:Background: The Anopheles gambiae salivary glands play a major role in malaria transmission and express a variety of bioactive components that facilitate blood-feeding by preventing platelet aggregation, blood clotting, vasodilatation, and inflammatory and other reactions at the probing site on the vertebrate host. Results: We have performed a global transcriptome analysis of the A. gambiae salivary gland response to blood-feeding, to identify candidate genes that are involved in hematophagy. A total of 4,978 genes were found to be transcribed in this tissue. A comparison of salivary gland transcriptomes prior to and after blood-feeding identified 52 and 41 transcripts that were significantly up-regulated and down-regulated, respectively. Ten genes were further selected to assess their role in the blood-feeding process using RNAi-mediated gene silencing methodology. Depletion of the salivary gland genes encoding D7L2, anophelin, peroxidase, the SG2 precursor, and a 5'nucleotidase gene significantly increased probing time of A. gambiae mosquitoes and thereby their capacity to blood-feed. Conclusions: The salivary gland transcriptome comprises approximately 38% of the total mosquito transcriptome and a small proportion of it is dynamically changing already at two hours in response to blood feeding. A better understanding of the salivary gland transcriptome and its function can contribute to the development of pathogen transmission control strategies and the identification of medically relevant bioactive compounds. Salivary glands from blood-fed vs. unfed A. gambiae. 3 replicates.
