Project description:Global warming and rising temperature significantly increase the incidence of heat stress, which is known to affect the process of inflammation and aging. However, the effect of heat stress on skin melanogenesis is not fully known. We found that healthy foreskin tissues underwent significant pigmentation when exposed to 41℃. Furthermore, heat stress promoted melanogenesis in pigment cells by increasing the paracrine effects of keratinocytes. High-throughput RNA sequencing showed that heat stress activates the Hedgehog (Hh) signaling pathway in keratinocytes. The agonists of Hh signaling promote the paracrine effect of keratinocytes on melanogenesis. In addition, TRPV3 agonists activate the Hh signaling in keratinocytes and augment its paracrine effect on melanogenesis. The heat-induced activation of Hh signaling is dependent on TRPV3-mediated Ca2+ influx. Heat exposure promotes melanogenesis by increasing the paracrine effects in keratinocytes via the TRPV3/Ca2+/Hh signaling pathway. Our findings provide insights into the mechanisms of heat-induced skin pigmentation.

Project description:To understand the impact of dysfunctional TRPV3 on keratinocyte proliferation and differentiation, we conducted transcriptomic analysis on cells that express cloned different TRPV3 mutations identified in focal palmoplantar keratoderma (FPPK) patients and identified a number of perturbed pathways associated with epidermal cells construction and development. We also analyzed the molecular changes of skin biopsy samples from patients. Our data suggests that TRPV3 dysfunction inhibits keratinocyte differentiation, actives apoptosis pathway resulted in cell death, and disturbs the balance between keratinocyte proliferation and differentiation processes in the skin.

We also analyzed the molecular changes of skin biopsy samples from patients. Our data suggests that TRPV3 dysfunction inhibits keratinocyte differentiation, actives apoptosis pathway resulted in cell death, and disturbs the balance between keratinocyte proliferation and differentiation processes in the skin. To explore the functional impact of the different TRPV3 mutations on cells, we cloned the wild type and mutant TRPV3 clones into expression vector. The wild-type human TRPV3 gene was amplified from cDNA made from a mixture of human tissue total RNA and cloned into pcDNA3.1 (Life Technologies, Carlsbad, CA). The accuracy of the cloned sequence was checked with Sanger sequencing. Quick Change II XL site-directed mutagenesis kit (Agilent, Santa Clara, CA) was used to introduce sequence changes corresponding to mutations observed in patients. The HEK293T cells were transfected using Lipofectamine 2000 (Life Technologies, Carlsbad, CA) according to the manufacturerâs instructions. Cells were also transfected with the same plasmid without insert as control.

Project description:TRPV3 is highly expressed in human skin and is involved in the development of inflammatory dermatoses. However, it remains unclear whether TRPV3 influences inflammation in human sebaceous glands and its role in the pathogenesis of acne. Here, we showed that TRPV3 expression was increased in the sebaceous glands of facial acne lesions and acne-like mice. TRPV3 increased the secretion of pro-inflammatory cytokines and chemokines in human SZ95 sebocytes, as well as the chemotaxis of neutrophils, which were the major immune cells found in acne lesions. We demonstrated that P.acnes promoted TRPV3 expression through regulating lipid profile especially upregulated arachidonic acid levels in human sebocytes. TRPV3 further upregulated TLR2 expression by promoting transcriptional factor p-FOSL1 expression and its binding to the TLR2 promoter, leading to downstream NF-κB signaling activation. Importantly, either genetic silencing or pharmacological inhibition of TRPV3 alleviated acne-like inflammation in mice, showing reduced acne-characteristic cytokines and chemokines production and neutrophil infiltration by inhibiting the TLR2-NF-κB axis. Thus, our study revealed the critical role of TRPV3 in sebocytes inflammation, which was involved in the development of acne, indicating that TRPV3 is a potential therapeutic target for acne and other disorders of the pilosebaceous unit.

Project description:Paracrine Hedgehog (Hh) signaling regulates growth and patterning in many Drosophila organs. We mapped chromatin binding sites for Cubitus interruptus (Ci), the transcription factor that mediates outputs of Hh signal transduction, and we analyzed transcription profiles of control and mutant embryos to identify genes that are regulated by Hh. Putative targets we identified include several Hh pathway components, most previously identified targets, and many targets that are novel. Analysis of expression patterns of pathway components and target genes gave evidence of autocrine Hh signaling in the optic primordium of the embryo. And, every Hh target we analyzed that is not a pathway component appeared to be regulated by Hh in a tissue-specific manner. We present evidence that Hh-dependent tissue specificity is dependent upon transcription factors that are Hh-independent, suggesting that “pre-patterns” of transcription factors partner with Ci to make Hh-dependent gene expression position-specific.

Project description:Epidermal transient receptor potential (TRP) channels are involved in complex interactions between the peripheral nervous system and the immune system in atopic dermatitis (AD). Recently, we identified that TRPV3 interacts with protease-activated receptor 2 (PAR2) to mediate non-histaminergic itch. However, the downstream molecular mechanisms following TRPV3 activation in keratinocytes remain unclear.This study aims to investigate whether TRPV3 channels regulate mast cells in the context of AD.

Project description:We identified a number of affected pathways through transcriptome analysis on the skin biopsy samples of the FPPK patients. Our findings suggest that TRPV3 dysfunction may increase apoptotic activity, inhibit keratinocyte differentiation and disturb the intricate balance between proliferation and differentiation state of keratinocytes in the skin. To understand the effect of TRPV3 mutation, transcriptome of HaCaT cell lines transfected with mutant TRPV3 were profiled in time-course manner (16, 24 and 40hr).
