Bcl-2 protein expressing agent, apoptosis inhibiting agent, and agent for preventing ultraviolet damage to dns of an epidermal cell

摘要

An object of the present invention is to provide an apoptosis inhibiting agent which inhibits apoptosis of a cell having a DNA which is directly or indirectly damaged with ultraviolet-rays or the like, enhances the tissue restoring property of a cell, can be added to various drugs, and can be expected to be widely applied. An apoptosis inhibiting agent for an epidermal cell, containing a water and ethanol-soluble glycyrrhiza extract as an active ingredient. The apoptosis inhibiting agent has an anti-apoptotic factor due to expression of BLC-2 protein, and has the property of preventing a DNA damage due to ultraviolet-rays. The agent alleviates the DNA damage of an epidermal cell due to ultraviolet exposure and, moreover, does not abnormally or adversely affect a normal skin cell.
