U. parvifolia elevates cAMP production and enhances VASP and PKAαβγ phosphorylation. (A) cAMP immunoassay performed for collagen-stimulated washed platelets pre-treated with various U. parvifolia extract concentrations, vehicle, or forskolin. (B) Immunoblotting analysis conducted for the phosphorylation of total VASP, p-VASPser157, and PKAαβγ extracted from platelets. Representative immunoblot images and graphs plotted for the data (mean ± SD values) obtained from at least four independent experiments are shown. *p < 0.05 and ***p < 0.001 versus agonist-treated group.
