概括
人体血清白蛋白中的活性氧物种 (ROS) 添加物与非霍奇金淋巴瘤 (NHL) 风险有关. 在ROS附加物和微生物转位的性别特异性可能会导致男性的NHL发病率.
科学领域:
- 生物化学 生物化学
- 在瘤学瘤学.
- 蛋白质组学是指蛋白质组学.
背景情况:
- 在男性中非霍奇金淋巴瘤 (NHL) 的较高发病率仍然不明确.
- 反应性氧物种 (ROS) 与NHL病因有关,但很难在存档样本中直接测量.
研究的目的:
- 调查人类血清白蛋白 (HSA) 中稳定的ROS添加物与NHL风险之间的关联.
- 为了探索与NHL相关的ROS adduct配置文件的性别特异性差异.
主要方法:
- 在67例NHL病例和82例对照病例的样本上使用液体染色学高分辨率质谱学进行HSA的非向添加学.
- 回归和分类方法,以确定与NHL相关的ROS adduct特征在所有受试者中,并分别在男性和女性中.
主要成果:
- 67个HSA-adduct特征被量化,在性别之间发现了不同的关联.
- 总体而言,与NHL有关的是三种引体特征,七种与男性有关,五种与女性有关.
- 两性之间 adducts 的差异集群表明在NHL 发展中存在不同的操作途径.
结论:
- 附加物,特别是Cys34氧化产物和二硫化物,在NHL病因学中涉及ROS和氧化还原生物学.
- 饮食和酒精消费的性别差异可能解释了 adduct 概况的差异.
- 与微生物代谢相关的甲二硫化添加物在男性NHL病例中更为丰富,这表明微生物转移是男性潜在的危险因素.

01:11Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
