概括

ERLIN1 p.Ile291Val变体提供了对代谢功能障碍相关的脂肪性肝病 (MASLD) 的保护. 这种基因变异似乎是一种功能增益突变,影响脂质水平和肝酶.

科学领域:

遗传学是一个遗传学.
代谢疾病代谢疾病
肝脏疾病肝脏疾病

背景情况:

ERLIN1 p.Ile291Val单核酸多态性 (rs2862954) 与防止脂肪性肝病 (SLD) 有关.
这种变异对代谢表型的确切影响尚不清楚.

研究的目的:

调查ERLIN1 p.Ile291Val变体与代谢表型之间的关联.
确定变体对发展代谢功能障碍相关脂肪性肝病 (MASLD) 的风险的影响.

主要方法:

使用来自英国生物银行 (UKB),宾夕法尼亚医学生物银行 (PMBB) 和我们所有人研究队列的数据,采用了基因组第一方法.
分析包括与ERLIN1 p.Ile291Val变体相关的代谢表型,肝酶和脂质配置文件.

主要成果:

ERLIN1 p.Ile291Val载体显示肝酶 (ALT,AST) 和脂质 (三糖化物,LDL-C,ApoB,HDL-C,ApoA1) 的水平发生变化,这种变化取决于基因组的剂量.
同卵同卵的携带者具有显著降低的MASLD风险 (aOR=0.92).
在 TM6SF2 p.Glu167Lys 变异的携带者中,保护作用减弱,预测功能丧失的 ERLIN1 变异具有相反的效果,这表明 ERLIN1 p.Ile291Val 是功能获取的变异.

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Long-patch Base Excision Repair

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Regulation of the Unfolded Protein Response

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
