Study of the activation of the NF-κB transcriptional regulator in a Caco-2 cell layer transfected with an alkaline phosphatase (SEAP) reporter vector. Measurements of the SEAP activity were carried out after incubation of the Caco-2 cell layer without or with stimulation with IL-1β (2 ng/ml), the AminoAlta™ probiotic formulation, and different partially hydrolyzed vegetal protein commercial preparations (PHVPs). RUNFA, relative units of NF-κB activation, calculated as normalized SEAP activity. Asterisks indicate statistically significant differences according to a two-tailed unpaired Student’s t-test. ***, p < 0.001; **, p < 0.01; *, p < 0.05; n. s., not significant.
