Effect of Glycyrrhizin on the Aoptosis of Melanoma Cells in Mel/ret Transgenic Mice

Glycyrrhizin이 Mel/ret transgenic mice에서의 melanoma 세포의 apoptosis에 미치는 영향

The effect of glycyrrhizin on melanoma cells was investigated. DNA fragmentation in cultured melanoma cells was promoted by the addition of glycyrrhizin in a dose dependent manner. Administration(i.m.) of glycyrrhizin to Mel/ret transgenic mice resulted in apoptosis induction, reduction of mitochondrial transmembrane potential in melanoma cells. Decreased B220+ B cells were recovered by the treatment of glycyrrhizin in splenocytes and mesenteric lymph node cells, while Thy-1+ T cells were not influenced. Results suggested that glycyrrhizin acted as an inducer of apoptosis of melanoma cells and an immuno-potentiator via recovered B lymphocyte population in Mel/ret transgenic mice.
