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: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: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.

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 are indispensable for human thermoregulation and, similar to other mammalian skin appendages, form from multipotent epidermal progenitors. Limited understanding of how epidermal progenitors specialize to form these vital organs has precluded therapeutic efforts toward their regeneration. Herein, we applied single-nucleus transcriptomics to compare the expression content of wild-type, eccrine-forming mouse skin to that of mice harboring a skin-specific disruption of Engrailed 1 (En1), a transcription factor that promotes eccrine gland formation in humans and mice. We identify two concurrent but disproportionate epidermal transcriptomes in the early eccrine anlagen: one that is shared with hair follicles and one that is En1 dependent and eccrine specific. We demonstrate that eccrine development requires the induction of a dermal niche proximal to each developing gland in humans and mice. Our study defines the signatures of eccrine identity and uncovers the eccrine dermal niche, setting the stage for targeted regeneration and comprehensive skin repair.

Project description:In clinical routine, the diagnosis of cystic fibrosis (CF) is still a challenge due to the limitations of diagnosis guidelines and tests. A diagnosis test of choice, the sweat test measures eccrine sweat chloride concentration as a byproduct of the eccrine sweat gland CFTR function. Despite the combined use of CFTR genotyping and direct physiologic testing of CFTR function, reports of inconclusive diagnosis justified the need for alternative tests and new biomarkers. Meanwhile, eccrine sweat composition has already been linked to disease-specific profiles of non-electrolytes (i.e. proteins, peptides and metabolites). In this study, we analyzed sweat samples from 28 healthy volunteers and 14 CF patients by UHPLC-Q-Orbitrap-based Shotgun proteomics, to address CF-related changes in sweat protein composition and abundance. Over 1000 proteins were identified and quantified in a label-free manner. Beside similar protein composition, enrichment and functional classifications, HV and CF samples were grouped apart since protein abundance profiles were significantly correlated with CF status and degree of severity (ΔF508 homozygous and pancreatic insufficiency onset). Four-hundred and two proteins in CF-specific abundance, 68 proteins in genotype-specific abundance and 71 proteins in abundance related to pancreatic status, respectively, highlighted eccrine gland cell perturbations in protein biosynthesis & trafficking, CFTR proteostasis & membrane stability, cell-cell adherence, membrane integrity & cytoskeleton crosstalk. Cytoskeleton-related biomarkers were of utmost interest because of consistent abundances between CF sweat and other CF tissues. Nine clinical CF diagnosis biomarker (CUTA, ARG1, EZR, AGA, FLNA, MAN1A1, MIA3, LFNG, SIAE) and 5 CF severity biomarker (ARG1, GPT, MDH2, EML4 (ΔF508 homozygous), MGAT1 (pancreatic insufficiency)) candidates were deemed suitable for further verification.

Project description:We performed a global proteomic profile of eccrine sweat sampled from patients with active pulmonary TB, other lung diseases (non-TB disease), and healthy controls. A comparison of proteomics results between Active-TB, Non-TB and Healthy Controls was done in search for proteins unique to the active TB-patient cohort as well as proteins unique to those without TB disease. We conclude tthat global proteomic profiling of eccrine sweat collected from TB and non-TB patients is a viable approach for the identification of unique proteins differentially present based on clinical cohort. These proteins may represent unique biomarker profiles that upon further verification and validation could be used to develop a non-sputum based test for diagnosis of active TB.
