概括

终身不活化APOB基因显著降低心血管风险,但会增加慢性肝病 (CLD) 风险,特别是在肥胖和糖尿病患者中. 这突显了心血管保护和肝脏健康之间的关键平衡.

科学领域:

遗传学和心血管医学
肝病学和代谢疾病

背景情况:

终身阿波利波蛋白B (APOB) 基因失活可以降低LDL-C和心血管疾病 (CVD) 的风险.
然而,它会影响肝脂蛋白的输出,增加慢性肝病 (CLD) 的风险.
对这种风险的常见稳定性因子的影响以及APOB变异载体中心血管疾病保护和CLD风险之间的长期平衡尚未得到充分理解.

研究的目的:

评估APOB功能丧失 (LoF) 变体患者的长期心血管和慢性肝病 (CLD) 风险.
评估常见的稳定性因素如何改变这些风险.

主要方法:

来自241个APOB LoF载体和410,721个非载体的英国生物银行数据的分析.
基于稳定性风险因素的分层:年龄,性别,糖尿病,BMI,酒精摄入量和PNPLA3-rs738409基因型.
使用Python和R. 评估与转氨酶水平,CLD和动脉样硬化心血管疾病 (ASCVD) 结果的关联.

主要成果:

携带APOB的携带者表现出~35%较低的LDL-C和apoB水平,降低了甘油三和Lp (a).
携带者具有较高的基线ALT和AST,增加了CLD的流行率和发病率,特别是当与糖尿病和肥胖症相结合时.
携带APOB的人患ASCVD风险降低了57%,但患CLD风险增加 (3.48事件/1000人年).

结论:

从APOB LoF变种长期低的LDL-C降低了ASCVD风险,但增加了CLD风险,特别是在糖尿病和肥胖症中.
这些发现强调了需要平衡心血管益处与阿波B向治疗的肝脏安全问题.

Enrichment of Mammalian Tissues and Xenopus Oocytes with Cholesterol

Two methods of cholesterol enrichment are presented: the application of cyclodextrin saturated with cholesterol to enrich mammalian tissues and cells, and the use of cholesterol-enriched phospholipid-based dispersions (liposomes) to enrich Xenopus oocytes. These methods are instrumental for determining the impact of elevated cholesterol levels in molecular, cellular, and organ...
