Aging and metabolic disorders feedback and promote each other and are closely related to the occurrence and development of cardiovascular disease, type 2 diabetes, neurodegeneration and other degenerative diseases. Liupao tea is a geographical indication product of Chinese dark tea, with a "red, concentrated, aged and mellow" flavor quality. In this study, the aqueous extract of aged Liupao tea (ALPT) administered by continuous gavage significantly inhibited the increase of visceral fat and damage to the intestinal-liver-microbial axis in high-fat modeling of SAMP8 (P8+HFD) mice. Its potential mechanism is that ALPT significantly inhibited the inflammation and aggregation formation pathway caused by P8+HFD, increased the abundance of short-chain fatty acid producing bacteria , and , and had a calorie restriction effect. The results of the whole target metabolome network pharmacological analysis showed that there were 139 potential active components in the ALPT aqueous extract, and the core targets of their actions were SRC, TP53, AKT1, MAPK3, VEGFA, EP300, EGFR, HSP90AA1, CASP3, etc. These target genes were mainly enriched in cancer, neurodegenerative diseases, glucose and lipid metabolism and other pathways of degenerative changes. Molecular docking further verified the reliability of network pharmacology. The above results indicate that Liupao tea can effectively delay the body's degenerative changes through various mechanisms and multi-target effects. This study revealed that dark tea such as Liupao tea has significant drinking value in a modern and aging society.
衰老与代谢紊乱相互反馈、相互促进,与心血管疾病、2型糖尿病、神经退行性变等退行性疾病的发生发展密切相关。六堡茶是中国黑茶的地理标志产品,具有“红、浓、陈、醇”的风味品质。本研究中,连续灌胃给予衰老六堡茶水提物(ALPT)可显著抑制SAMP8(P8+HFD)小鼠高脂造模过程中内脏脂肪的增加以及肠-肝-微生物轴的损伤。其潜在机制为ALPT显著抑制P8+HFD引起的炎症和聚集形成途径,增加产短链脂肪酸细菌的丰度,且具有热量限制作用。全靶标代谢组网络药理学分析结果显示,ALPT水提物中有139种潜在活性成分,其作用的核心靶点为SRC、TP53、AKT1、MAPK3、VEGFA、EP300、EGFR、HSP90AA1、CASP3等。这些靶基因主要富集在癌症、神经退行性疾病、糖脂代谢等退行性变化途径中。分子对接进一步验证了网络药理学的可靠性。上述结果表明,六堡茶可通过多种机制和多靶点效应有效延缓机体的退行性变化。本研究揭示了六堡茶等黑茶在现代老龄化社会中具有显著的饮用价值。
