Effects of L. rhamnosus CY12 on mRNA expressions related to inflammation, TJ proteins, and antioxidant enzymes in LPS-induced Caco-2 Cells. (A): mRNA expression of IL-1β. (B): mRNA expression of TNF-α. (C): mRNA expression of IL-6. (D): mRNA expression of IL-8. (E): mRNA expression of NF-κB. (F): mRNA expression of TLR4. (G): mRNA expression of occludin. (H): mRNA expression of ZO-1. (I): mRNA expression of claudin. (J): mRNA expression of CAT. (K): mRNA expression of SOD. (L): mRNA expression of GSH-Px. Note: C represents uninduced Caco-2 cells; L, M, and H represent LPS-induced Caco-2 cells co-incubated with 107, 108, and 109 cfu/mL L. rhamnosus CY12, respectively; LPS represents LPS-induced Caco-2 cells. Data were presented as mean ± SEM. Means with the different letters are significantly different p < 0.05.
