Outline of Final Research Achievements |
We indicated that RanBP2 and RanGAP1 are overexpressed and that the phosphorylation of S53 in MCM2 is significantly upregulated not only in the spinous layers but also in the basal layers of psoriatic epidermis. We also suggest that RanBP2 and RanGAP1 regulate the intracellular localization of LEDGF and phosphorylated Y705 STAT3 via the PI3K/Akt and MAPK /Erk1/2 pathways in our psoriatic model systems of HaCaT cells. These findings suggest that RanBP2 and RanGAP1 may play pivotal roles in the pathogenesis of psoriasis via translocation of LEDGF and phosphorylated Y705 STAT3 into the nucleus in psoriatic KCs Moreover, we created a KC speficif LEDGF transgenic mouse.
