Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease and associated with metabolic imbalance. Luteolin (LUT) reportedly exhibits anti-inflammatory activity. However, its regulatory effects on metabolites remain indistinct. Here, the effects of LUT on immune response and oxidative stress in UC were determined. Serum metabolomics profiles of UC rats treated with LUT were obtained utilizing liquid chromatography-mass spectrometry. The results revealed that LUT treatment alleviated colon tissue injury, colon shortening, weight loss, and inflammatory response in UC rats. Additionally, the levels of superoxide dismutase and total antioxidant capacity were elevated, but malondialdehyde content was reduced in serum of UC rats, while these changes were abrogated by LUT. Metabolomics analysis unveiled that l-malic acid, creatinine, l-glutamine, and l-lactic acid levels were remarkably decreased, while dimethyl sulfone, 5-methylcytosine, cysteine-S-sulfate, and jasmonic acid levels were notably increased after LUT treatment. Furthermore, differential metabolites primarily participated in d-glutamine and d-glutamate metabolism, glutathione metabolism, and citrate cycle pathways. In summary, these results demonstrated that LUT improved immune response, alleviated oxidative stress, and altered metabolites in UC rats. This study lays the root for further exploring the mechanism of LUT in the treatment of UC.

[PMID: 36190650 DOI: 10.1007/s11748-022-01874-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/10/2022] [Indexed: 01/19/2023]
Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors of the gastrointestinal tract. Circular RNAs (circRNAs) are involved in the pathogenesis of cancer. This study aimed to elucidate the role and molecular mechanism of circ_0008726 in ESCC. METHODS The expression levels of circ_0008726, microRNA (miR)-206 and homeobox A13 (HOXA13) were detected by quantitative real-time PCR (QRT-PCR). Cell counting kit-8 (CCK-8) and 5-Ethynyl-2'-deoxyuridine (EdU) assays were conducted to detect the proliferative ability of ESCC cells. Apoptosis and invasion of ESCC cells were detected by flow cytometry and transwell assays. Tube formation assay was used to detect the angiogenesis of ESCC cells. The expression of related proteins was detected by western blot analysis. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were performed to confirm the interactions among circ_0008726, miR-206 and HOXA13. Xenograft mice model was established to study the in vivo effect of circ_0008726 knockdown. RESULTS Expression of circ_0008726 was up-regulated in ESCC tissues and cells. Knockdown of circ_0008726 repressed proliferation, invasion, angiogenesis, and promoted apoptosis of ESCC cells. Circ_0008726 acted as a sponge for miR-206, and HOXA13 was a target of miR-206. The suppressive effects of circ_0008726 knockdown on cell proliferation, invasion, and angiogenesis were abated by miR-206 down-regulation. Meanwhile, overexpression of HOXA13 partially reversed the suppressive effects of miR-206 enrichment on ESCC cell malignant behaviors. Knockdown of circ_0008726 inhibited ESCC tumor growth in vivo. CONCLUSION In short, circ_0008726 exerted the carcinogenic effects to regulate the proliferation, invasion, angiogenesis and apoptosis of ESCC cells by targeting miR-206/HOXA13 axis.
