Charakterisierung der UVA induzierten metabolischen Veränderungen in Melanomen in vitro und in vivo und deren therapeutische Interventionsmöglichkeiten
Zusammenfassung der Projektergebnisse
Taken together, we could find new metabolic pathways which are changed upon UVA irradiation. Furthermore we unraveled metabolic changes upon UVA irradiation which are not limited to human melanoma cells and are also present in murine and human melanocytes, keratinocytes and fibroblasts. The UVA enhanced lactic acid production and secretion of these cells could promote progression of initial melanomas and contribute to UVA induced immune suppression. Many of the UVA induced metabolic changes seem to be involved in antioxidant defense of UVA induced ROS. In the scenario of UVA-induced glycolysis and pyruvate production the melanoma cells or fibroblasts, keratinocytes and melanocytes could use elevated pyruvate level as additional antioxidant. As pyruvate could be an important metabolite involved in UVA induced antioxidant defense, the interference with glycolysis seems to be an interesting target disturbing UVA induced melanoma metabolism. This is subject to ongoing research in our group. Further UVA-induced metabolic changes in human skin cells and murine skin and the role of pyruvate for ROS detoxification are subject to ongoing research.
