Furthermore, decreased levels of MDA and increased expression of the tight junction proteins (TJPs) ZO-1, claudin-3, and occludin were observed in MEECs in response to C. butyricum [86], suggesting that C. butyricum significantly attenuates inflammatory changes and relieves endometritis by inhibiting the NF-κB signaling pathway. The gene discussed is NFKB1; the disease is endometritis.
