摘要
Estrogen (E) and progesterone (P) are the major female hormones and are secreted with changing concentration ratios throughout the menstrual cycle. These hormones have been studied individually regarding their physiological function in the skin, but their concentration ratio (E/P) and its effect on the skin has not yet been investigated. The purpose of this study was to clarify the effect of the E/P ratio on skin barrier function. The menstrual cycle was divided into the menstrual, follicular, ovulation, and luteal phases.The E/P concentration ratios corresponding with each phase were added to a three-dimensional epidermal model or normal human epidermal keratinocytes for 5 days. Gene and protein expression levels of several markers of cell differentiation, including loricrin (LOR) and transglutaminase (TGase), were quantified by real-time PCR and western blotting, respectively. Transepidermal water loss (TEWL) of the three-dimensional epidermal model was measured, and ceramide content was quantified by thin-layer chromatography.Gene expression of the epidermal differentiation markers, LOR and TGase, increased when applying the concentration ratio of E/P associated with the menstrual and luteal phases. The LOR protein level decreased from menstrual to luteal phases, and the TGase protein level increased from menstrual to luteal phases. During the same phases, ceramide NS increased and TEWL decreased.Skin barrier function was improved by culturing cells at specific E/P concentration ratios, which would, therefore, be considered beneficial for female skin. This suggests that dysregulated E/P concentration ratios may be the cause of certain skin problems.
