Project description: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, lack of reabsorption of Cl- ions from reabsorptive duct of eccrine sweat gland is a major feature of cystic fibrosis. Understanding the proteome of eccrine sweat glands is important for understanding the physiology of sweat formation. In spite of this, no systematic transcriptome or proteome analysis of eccrine 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 showed the enrichment in protein digestion/absorption and salivary secretion, while the transcriptome data did not show any enrichment for a specific pathway. This study also enabled us to confirm 2 missing proteins. Integrating 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: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.

Project description:Eccrine sweat glands contribute to the regulation of human body temperature. Acquired idiopathic generalized anhidrosis (AIGA) is extensive anhidrosis of unknown etiology, that causes the fatal heatstroke and skin dryness. Eccrine sweat glands in hidrotic and anhidrotic skin areas were excised from paraffin-embedded skin specimens from AIGA patients, and the gene expression was profiled by RNA-sequencing. We analyzed the RNA samples to clarify the difference in gene expression between hidrotic and anhidrotic skin areas from AIGA patients.

Project description:Sweat glands are abundant glands of our body and essential for thermoregulation. Like mammary glands, they originate from epidermal progenitors. However, they display few signs of cellular turnover, and whether they have stem cells and tissue regenerative capacity remain largely unexplored. Here we address these issues. Using lineage-tracing, we identify multipotent progenitors in sweat duct that transition to unipotency after developing the sweat gland. In characterizing four adult stem cell populations of glandular skin, we show that they display distinct regenerative capabilities and remain unipotent when healing epidermal, myoepithelial-specific and luminal-specific injuries. We devise purification schemes, isolate and transcriptionally profile progenitors. Exploiting molecular differences between sweat and mammary glands, we show that only some progenitors regain multipotency to produce de novo ductal and glandular structures, but that these can retain their identity even within certain foreign microenvironments. Our findings provide new concepts about glandular stem cells and sweat gland biology.

Project description:K and Cl channels play critical role for sweat secretion, however, individual K or Cl channels and their functions are largely unknown. By comparing expreession profilings between wild-type and Eda mutant Tabby footpads we identified 4 K and 2 Cl channels highly expressed in mouse eccrine sweat glands.
