1xbet 등록., Ltd. (Otsuka) has published an article in the peer-reviewed scientific journal,Photochemistry 1xbet 등록 Photobiologyentitled 'Infrared-A Irradiation-induced Inhibition of Human Keratinocyte Proliferation 1xbet 등록 Potential Mechanisms'.

This article describes for the first time that IRA radiation inhibits human epidermal keratinocyte proliferation 1xbet 등록 clarifies its inhibitory mechanism, by focusing on the regulatory mechanism for the activation of mTOR complex 1 (mTORC1).

The human epidermis has a self-renewing ability known as epidermal turnover, which is mediated by the proliferation of keratinocytes. It has been recognized that intrinsic aging 1xbet 등록 other factors suppress the proliferative activity, resulting in the retardation of epidermal turnover rate. Photoaging, which is both qualitatively 1xbet 등록 quantitatively different from chronological aging, is known to be associated with inhibition of keratinocyte proliferation. However, the molecular mechanisms involved in the inhibitory effect are incompletely understood.

1xbet 등록 believes that maintaining epidermal turnover rate is important for healthy skin and has been investigating the effects of sunlight on the proliferative activity of keratinocytes. The authors have demonstrated that IRA, which is known to promote photoaging of the dermis, inhibits the activity of mTORC1, an intracellular signaling molecule that plays a critical role in regulating cell cycle progression, and thereby inhibits cell proliferation of keratinocytes. Furthermore, it was revealed that there are at least two pathways by which the molecular mechanism inhibits the activity of mTORC1 upon IRA irradiation.

These findings suggest that prevention of IRA radiation from sunlight may contribute to preserve epidermal cell proliferation activity, leading to the maintenance of epidermal turnover rate that is required to maintain a healthy 1xbet 등록 youthful appearance skin. We believe that these findings provide new insights into the mechanisms of photoaging.
