ABSTRACT
Ulcerative colitis (UC) is a typical type of inflammatory bowl disease, which is accompanied by an increased risk of depression and anxiety-related psychological symptoms. Betaine is a naturally derived compound that can function as an anti-inflammatory drug and a neuromodulator. In-depth exploration of the potential role of betaine in treating UC-related depression and anxiety is crucial. This study aimed to elucidate the effects of betaine on UC-related depression and anxiety and clarify the underlying mechanisms. A dextran sulfate sodium (DSS)-induced mice model was established by 4% DSS drinking ad libitum for 7 days. The colonic injury was measured using hematoxylin-eosin (HE) staining and Alcian blue-periodic acid Schiff (AB-PAS) staining. Depression and anxiety-like behaviors were separately evaluated using a forced swimming test (FST), a tail suspension test (TST), a light-dark box test (LDBT), and an open field test (OFT). Immunohistochemistry was used to detect DNA damage and neurogenesis in the hippocampus. Western blotting was applied to detect the protein levels of macrophage polarization in mice colons and the alteration of mitochondrial dysfunction and the cGAS-STING pathway in the hippocampus. Betaine strongly alleviated mucosal structural disorder and mucin secretion reduction and promoted M2-macrophage polarization in the colon of DSS-treated mice. In addition, betaine could mitigate depression- and anxiety-like behaviors in DSS-treated mice, reduce the DNA damage and mitochondrial dysfunction, and inhibit the cGAS-STING signaling pathway. Our study reveals the antidepression/anxiety effects of betaine and further demonstrates the potential mechanism by which betaine inhibits DNA damage and mitochondrial dysfunction to block the cGAS-STING pathway, thereby repairing neurogenesis in the hippocampus.
