饲用大麦(Hordeum vulgare L.)叶(BL)是一种受欢迎的功能性食品,已知具有潜在的健康益处;然而,BL在预防结直肠癌方面的作用尚未得到研究。在这里,我们研究了BL在预防结直肠癌发生中的作用,并确定了相关的机制。BL补充剂可以防止体重减轻、减轻肿瘤形成并减轻用氧化偶氮甲烷(AOM)和硫酸葡聚糖钠(DSS)治疗的小鼠的组织损伤。此外,BL抑制结肠炎性酶的表达,同时改善粘膜屏障功能障碍。BL还降低了细胞增殖标记物水平的升高和参与β-连环蛋白信号传导的基因表达的增加。此外,微生物群分析显示,BL通过促进双歧杆菌的富集来防止AOM/DSS诱导的肠道微生物群失调。总体而言,这些数据表明,BL是一种有前途的膳食剂,用于预防结肠炎相关的结直肠癌。
Dietary barley (Hordeum vulgare L.) leaf (BL) is a popular functional food known to have potential health benefits; however, the effect of BL in colorectal cancer prevention has not been examined. Here, we examined the role of BL on the prevention of colorectal carcinogenesis and defined the mechanism involved. BL supplementation could protect against weight loss, mitigate tumor formation, and diminish histologic damage in mice treated with azoxymethane (AOM) and dextran sulfate sodium (DSS). Moreover, BL suppressed colonic expression of inflammatory enzymes, while improving the mucosal barrier dysfunctions. The elevated levels of cell proliferation markers and the increased expression of genes involved in β-catenin signaling were also reduced by BL. In addition, analyses of microbiota revealed that BL prevented AOM/DSS-induced gut microbiota dysbiosis by promoting the enrichment of Bifidobacterium. Overall, these data suggest that BL is a promising dietary agent for preventing colitis-associated colorectal cancer.
