In this study, we investigated the expression and putative role of Sox9 in epidermal keratinocyte. Immunohistochemical staining showed that Sox9 is predominantly expressed in the basal layer of normal human skin epidermis, and highly expressed in several skin diseases including psoriasis, basal cell carcinoma, keratoacanthoma and squamous cell carcinoma.

BACKGROUND Recently, autologous platelet-rich plasma (PRP) has attracted attention in various medical fields, including plastic and orthopedic surgery and dermatology, for its ability to promote wound healing. PRP has been tested during facelift and hair transplantation to reduce swelling and pain and to increase hair density. OBJECTIVE To investigate the(More)
BACKGROUND Café-au-lait macules (CALMs) are a common pigmentary disorder. Although a variety of laser modalities have been used to treat CALMs, their efficacies vary and dyspigmentation may develop. OBJECTIVE We evaluated the clinical efficacy and safety of a low-fluence 1064-nm Q-switched neodymium-doped yttrium aluminium garnet (Nd:YAG) laser for the(More)

Acne vulgaris is the most common disease of the pilosebaceous unit. The pathogenesis of this inflammatory disease is complex, involving increased sebum production and perifollicular inflammation. To identify effective agents for factors that induce acne vulgaris, we explored the pharmacological potential of epigallocatechin-3-gallate (EGCG), which has been(More)
BACKGROUND Aquaporins (AQPs) are a family of water transporting proteins present in many mammalian epithelial and endothelial cell types. Among the AQPs, AQP3 is known to be a water/glycerol transporter expressed in human skin. OBJECTIVE The relationship between the expression level of AQP3 and transpidermal water loss (TEWL) in the lesional and(More)
Terminal differentiation of skin keratinocytes is a vertically directed multistep process that is tightly controlled by the sequential expression of a variety of genes. To gain further insight into the molecular events involved in this process, we used suppression subtraction hybridization (SSH) and cDNA microarray analysis. Messenger RNAs were isolated(More)
S100A8 and S100A9 are members of the S100A8 protein family that exist as homodimers and heterodimers in neutrophils, monocytes, and macrophages. Recent studies have shown the pivotal roles of S100A8 and S100A9 in the propagation of inflammation and keratinocyte proliferation in psoriasis. We found significant up-regulation of S100A8 and S100A9 secretion(More)
BACKGROUND Radiation induces many cellular events leading to radiodermatitis. OBJECTIVES The aim of this study was to establish a radiodermatitis model using experimental animals, and to examine the expression profile of radiation-induced genes. METHODS Hairless mice were irradiated on the dorsal skin; then total RNAs were isolated and microarray(More)
BACKGROUND The extraneuronal cholinergic system has been implicated in numerous functions in the skin, such as terminal differentiation, barrier formation, sweat secretion and the microcirculation. However, the evidence for cholinergic signalling in sebaceous glands is lacking, and its role needs to be clarified. OBJECTIVE We investigated the role of(More)
