plasmin evokes an increase in both phosphoinositide hydrolysis and Fura-2/AM fluorescence in cultured cortical astrocytes. Plasmin activiates extracellular signal-regulated kinase and induces a rise in intracellular Ca2+ concentration and phopho-ERK1/2 levels

plasmin has no effect on ERK1/2 signaling or Ca2+ concentraion in primary cultured hippocampal neurons or hippocampal slices

plasmin induces scattering of HT-29-M6 cells in the presence of 12-myristate 13-acetate

plasmin induces a concentration-dependent transient elevation in the cytosolic Ca2+ concentrations

leukaemic cell line. In L5178Y cells with knock-out of the gene for annexin A2, the mRNA level of plasminogen is not substantially changed, but the protein level of plasmin is significantly lowered. mRNA and protein levels of S100A10 and fascin are lower in annexin A2 knock-out cells than in wild-type L5178Y cells

-
plasmin triggers expression and release of proinflammatory cytokines such as TNF-alpha and IL-6 in human monocyte-derived macrophages with a somewhat lower potency than the standard stimulus lipopolysaccharide. Plasmin-induced activation of JAK1, p38, ERK1/2, and NF-kappaB is indispensable for the cytokine expression

-
in CA1 pyramidal neuron, plasmin application potentiates the N-methyl-D-aspartate receptor-dependent component of miniature excitatory postsynaptic currents recorded from CA1 pyramidal neurons but has no effect on -amino-3-hydroxy-5-methyl-4-isoxazole propionate- or -aminobutyric acid receptor-mediated synaptic currents. Plasmin also increased N-methyl-D-aspartate-induced whole cell receptor currents recorded from CA1 pyramidal cells
Manually annotated by BRENDA team
-
steroid-treated ovariectomized mice deficient in tissue inhibitor of metalloprotease-1 and exposed to estrogen show a significant increase in plasmin activity. Increase is probably due to reduced expression of plasmin inhibitors serpinb7 and serpinb2
