Abstract
Evaporation of sweat on the skin surface is the major mechanism for dissipating heat in humans. The secretory capacity of sweat glands (SWGs) declines during aging, leading to heat intolerance in the elderly, but the mechanisms responsible for this decline are poorly understood. We investigated the molecular changes accompanying SWG aging in mice, where sweat tests confirmed a significant reduction of active SWGs in old mice relative to young mice. We first identified SWG-enriched mRNAs by comparing the skin transcriptome of Eda mutant Tabby male mice, which lack SWGs, with that of wild-type control mice by RNA-sequencing analysis. This comparison revealed 171 mRNAs enriched in SWGs, including 47 mRNAs encoding 'core secretory' proteins such as transcription factors, ion channels, ion transporters, and trans-synaptic signaling proteins. Among these, 28 SWG-enriched mRNAs showed significantly altered abundance in the aged male footpad skin, and 11 of them, including Foxa1, Best2, Chrm3, and Foxc1 mRNAs, were found in the 'core secretory' category. Consistent with the changes in mRNA expression levels, immunohistology revealed that higher numbers of secretory cells from old SWGs express the transcription factor FOXC1, the protein product of Foxc1 mRNA. In sum, our study identified mRNAs enriched in SWGs, including those that encode core secretory proteins, and altered abundance of these mRNAs and proteins with aging in mouse SWGs.

BURNS & TRAUMA 2021; 9:tkab013. [PMID: 34213515 PMCID: PMC8240535 DOI: 10.1093/burnst/tkab013] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 02/09/2021] [Indexed: 12/22/2022]
Abstract
Background Sweat glands (SGs) and hair follicles (HFs) are two important cutaneous appendages that play crucial roles in homeostatic maintenance and thermoregulation, and their interaction is involved in wound healing. SGs can be regenerated from mesenchymal stem cell-laden 3D bioprinted scaffolds, based on our previous studies, whereas regeneration of HFs could not be achieved in the same model. Due to the lack of an in vitro model, the underlying molecular mechanism of the interaction between SGs and HFs in regeneration could not be fully understood. The purpose of the present study was to establish an in vitro model of skin constructs with SGs and HFs and explore the interaction between these two appendages in regeneration. Methods To investigate the interaction effects between SGs and HFs during their regeneration processes, a combined model was created by seeding HF spheroids on 3D printed SG scaffolds. The interaction between SG scaffolds and HF spheroids was detected using RNA expression and immunofluorescence staining. The effects of microenvironmental cues on SG and HF regeneration were analysed by altering seed cell types and plantar dermis homogenate in the scaffold. Results According to this model, we overcame the difficulties in simultaneously inducing SG and HF regeneration and explored the interaction effects between SG scaffolds and HF spheroids. Surprisingly, HF spheroids promoted both SG and HF differentiation in SG scaffolds, while SG scaffolds promoted SG differentiation but had little effect on HF potency in HF spheroids. Specifically, microenvironmental factors (plantar dermis homogenate) in SG scaffolds effectively promoted SG and HF genesis in HF spheroids, no matter what the seed cell type in SG scaffolds was, and the promotion effects were persistent. Conclusions Our approach elucidated a new model for SG and HF formation in vitro and provided an applicable platform to investigate the interaction between SGs and HFs in vitro. This platform might facilitate 3D skin constructs with multiple appendages and unveil the spatiotemporal molecular program of multiple appendage regeneration.

Abstract
For several decades now, researchers, professional bodies, governments, and journals such as the journal of Experimental Dermatology have worked to reduce the number of animals used in experimentation. This review centres on investigations into how human sweat glands produce sweat and how that research has evolved over the years. It is hoped that this review will show that as methodologies advanced, sweat gland research has come to rely less and less on a variety of animal models as investigative tools and information is being primarily obtained through human and mouse material, with a view to further reductions in using animal models.

Abstract
Several studies have reported inducing adult cells into sweat gland-like cells; however, slow transition and low efficiency limit the potential for cell-based treatment. Here, we show that overexpression of the transcription factor FoxC1 was sufficient to reprogram epidermal cells to induced functional sweat gland-like cells (iSGCs). The iSGCs expressing secreting-related genes, had a global gene expression profile between fetal SGCs (P5) and adult SGCs (P28). Moreover, iSGCs transplanted into the burn mice model facilitated wound repair and sweat gland regeneration. We further demonstrated that the Foxc1 upregulated BMP5 transcription and BMP5 is responsible for the cell-type transition. Collectively, this study shows that lineage reprogramming of epidermal cells into iSGCs provides an excellent cell source and a promising regenerative strategy for anhidrosis and hypohidrosis.

Abstract
BACKGROUND Cutaneous malformations are at times associated with some forms of congenital heart defects. Many a times subtle cutaneous phenotypes maybe overlooked as their significance on the lives of individuals is minimal. Lebanon represents an area of high consanguinity, where the rates can go beyond 70% in some districts. For the past 6 years, we have been studying several genodermatoses in Lebanon including those with cardiac malformations. OBJECTIVES The main aim of this study is to document the genetic basis of a familial case of Axenfeld-Rieger Syndrome (ARS) with a mild cutaneous phenotype represented histologically with degeneration/ absence of hair follicles and incomplete formation of sebaceous and eccrine glands, in addition to the cardiac and ocular phenotypes. METHODS Whole exome sequencing was performed on two identical-twins with ARS along with their affected father and non-affected mother. Sanger sequencing was used to confirm the mutation, and the effects of the mutations on protein function was assessed in vitro using transient transfections. RESULTS A novel mutation inFOXC1 designated p.L240Rfs*75 was found in both twins and their father. The affected individuals share also a rare documented variant in NFATC1 designated p.V197 M. Both were absent from 200 Lebanese exomes. Our in vitro results suggested a gain of function activity of the FOXC1/NFATC1 complex, confirming its documented role in controlling murine hair follicle stem cells quiescence and regeneration. CONCLUSION This is the first documented human case with a mutation inFOXC1 regulating multi-organ developmental pathways that reflect a conserved mechanism in cell differentiation and proliferation.

Abstract
Recently, Forkhead box C1 (FOXC1) has been identified to play important roles in human cancers. However, the clinical significance and biological role of FOXC1 in cervical cancer remains unclear. Here, we showed that FOXC1 was frequently overexpressed in cervical cancer versus adjacent non-tumor tissues. Overexpression of FOXC1 was significantly correlated with tumor stage (P=0.011), tumor size (P=0.034), stromal invasion (P=0.001), and lymph nodes metastasis (P=0.008). Survival analysis further suggested that high FOXC1 expression was significantly correlated with poor overall survival (P=0.007) and recurrence-free survival (P=0.003) in cervical cancer patients. Moreover, we found that knock-down of FOXC1 by short hairpin RNAi significantly suppressed cervical cancer cells proliferation, migration, and invasion in vitro. Mechanistic studies showed that the FOXC1 requires PI3K/AKT signaling for its regulation of cell proliferation, migration and invasion. Our findings indicate that FOXC1 plays an important oncogenic role in cervical cancer progression.

Abstract
The epidermis serves as a critical protective barrier between the internal and external environment of the human body. Its remarkable barrier function is established through the keratinocyte (KC) terminal differentiation program. The transcription factors specifically regulating terminal differentiation remain largely unknown. Using a RNA-sequencing (RNA-seq) profiling approach, we found that forkhead box c 1 (FOXC1) was significantly up-regulated in human normal primary KC during the course of differentiation. This observation was validated in human normal primary KC from several different donors and human skin biopsies. Silencing FOXC1 in human normal primary KC undergoing differentiation led to significant down-regulation of late terminal differentiation genes markers including epidermal differentiation complex genes, keratinization genes, sphingolipid/ceramide metabolic process genes and epidermal specific cell-cell adhesion genes. We further demonstrated that FOXC1 works down-stream of ZNF750 and KLF4, and upstream of GRHL3. Thus, this study defines FOXC1 as a regulator specific for KC terminal differentiation and establishes its potential position in the genetic regulatory network.
