Gordon Lauc: 我是糖基科学家,我们分析了超过20万人的蛋白质糖基化。起初,我们的目标是开发不同疾病的生物标志物,但在研究大型人群队列时,我们发现年龄是一个强混杂因素,老年健康人的指标与患病年轻人的指标相似。我们意外地发现,糖基化可以作为生物钟,反映生活方式的选择和经历,甚至可以逆转。糖基化年龄测试可以量化我们对自身造成的损害,并反映生活方式的选择和经历。 我们发现,随着年龄增长,糖基化会发生改变,从而促进炎症,并导致大多数复杂疾病的发生。基于糖基化的生物钟可以逆转,例如,减肥可以使糖基化年龄倒退。糖基化与表观基因组之间存在强烈的相互作用,但我们测量的糖基化是由骨髓中浆细胞的表观基因组编码的。 健康的生活方式因人而异,糖基化年龄测试可以帮助我们个性化干预。糖基化会在疾病诊断前数年甚至十年发生变化,可以作为疾病风险的早期预警。糖基化年龄测试仅能提供生物年龄信息,不能用于疾病诊断。糖基化年龄测试可以帮助我们监控生活方式干预措施的效果,并提供客观证据。 与其他生物钟相比,糖基化年龄测试具有更可靠的数据和更强的科学依据。糖基化测试的优势在于其明确的生物学机制和可靠的数据。目前,糖基化年龄测试等生物钟测试在美国通常不被保险公司报销,因为年龄不被视为疾病。糖基化年龄测试可以帮助人们找到最适合自己的健康干预措施。 Robert Lufkin: 作为一名医生,我对基于炎症标志物,特别是糖基化的替代生物年龄测量系统很感兴趣。许多听众听说过与糖化血红蛋白A1C相关的糖化作用以及高血糖水平造成的损害。但我想了解糖基化究竟是什么,以及它与糖化的区别。 我们讨论了其他生物钟,例如DNA表观遗传甲基化时钟,它控制表观基因组。基因在短期内不会改变,但我们的表观基因组可以通过我们的生活方式选择和环境来编程。糖基化似乎与之类似,它反映了我们的生活方式选择和生活经历。随着年龄增长,糖基化会呈现出一致的模式,从而决定一个“生物年龄”,我们可以用它与时间年龄进行比较。 基于糖基化的生物年龄测试的价值与其他生物钟相比,例如DNA甲基化表观遗传时钟,以及如何选择合适的测试。糖基化年龄测试的成本以及未来是否有可能降低成本或是否有替代方案。 最后,我们讨论了炎症是许多疾病的根本原因,以及如何利用糖基化年龄测试等工具尽早发现疾病风险,并通过改变生活方式来降低风险。

Chapters
Glycosylation is a sophisticated enzymatic process that modifies proteins with complex oligosaccharides called glycans, unlike glycation. It's crucial for multicellular organisms, impacting protein structure and function, and is modifiable throughout life by lifestyle choices. The focus is on immunoglobulins G, the antibodies of our immune system.
  • Glycosylation is a complex enzymatic process distinct from glycation.
  • Glycans modify proteins, impacting their function.
  • Glycosylation is essential for multicellular life.
  • Glycans can be modified throughout life by lifestyle choices.
  • The study focuses on the glycosylation of immunoglobulins G (antibodies)

Shownotes Transcript

This week we explore the secrets to a longer, healthier life with our special guest, Dr. Gordon Lauc, a renowned professor of biochemistry and molecular biology. In today’s episode, we promise to transform your understanding of aging by introducing a revolutionary approach to measuring biological age through glycosylation. Unlike the familiar concept of glycation tied to sugar levels, glycosylation involves complex enzymatic processes that impact our immune system and overall health. Discover how these glycan modifications can serve as a biological clock, reflecting your lifestyle choices and even reversing biological age.Join us as we decode the relationship between age, glycans, and disease risks. Through Dr. Lauc's extensive research involving large population studies, we reveal how inflammation-driven changes in glycans can predict serious health conditions like cardiovascular diseases, diabetes, and inflammatory disorders such as IBD and lupus. Understand why aging is a significant confounder in health assessments and learn how glycan changes can provide early warnings about disease risks, giving you actionable insights to modify your lifestyle and manage these risks effectively.Finally, explore the nuances that set glycan-based tests apart from DNA methylation clocks. Don’t miss Dr. Lauc's invaluable tips on maintaining your health and reducing your biological age. Stay tuned for exclusive insights that could revolutionize your approach to aging and wellness.(15% off with this link):  https://glycanage.com/price-and-plans?discount=ROBERTLUFKIN)
