A group of the concentrations of inactivated Staphylococcus aureus(0,104,105,106,107,108,109cfu/mL)and of peptidoglycan(PG)(0.0,0.1,1.0,10.0μg/mL)were selected to induce the expression of regenerating proteinⅢγ(Reg IIIγ)in porcine intestinal epithelial cells(IPEC-J2).The levels of RegIIIγm RNA and protein were detected by q PCR and western blot assay,and the expression variations of RegⅢγ,P65,P38,C-Jun amino terminal kinase(JNK)and extracellular regulatory protein kinase(ERK)were analyzed to further explore the molecular mechanism of Reg...
