Panax notoginseng saponins induced up-regulation, phosphorylation and binding activity of MEK, ERK, AKT, PI-3K protein kinases and GATA transcription factors in hematopoietic cells

Objective To investigate the effects of panax notoginseng saponins (PNS) on expression, regulation and phosphorylation of multiple protein kinases in mitogen activated protein kinase (MAPK) intracellular signal pathway and GATA transcription factors in hematopoietic cells, so as to explore its mechanism of proliferation and differentiation activity on hematopoiesis.
