Xu et al., Cancer Res 2007
(Brain Neoplasms...) :
EGFR activation results in enhanced cyclooxygenase-2 expression through p38 mitogen activated protein kinase dependent activation of the Sp1/Sp3 transcription factors in human gliomas ... Enhanced DNA binding by Sp1/Sp3 requires p38-MAPK activity and correlates with increased phosphorylation of the Sp1 transcription factor

PMA increased MAPK dependent Sp3 phosphorylation, Sp3-VDR interactions, and Sp3 binding to the hCYP24A1 promoter
