概括
自身免疫性甲状腺炎 (AIT) 增加了乳腺癌的风险,而7-甲基丁起到了关键的调解作用. 这项研究澄清了因果关系,并确定了与AIT和乳腺癌之间的关联有关的特定代谢物.
科学领域:
- 内分泌学和瘤学的内分泌学和瘤学.
- 代谢学 代谢学 代谢学
- 遗传学 是一个遗传学.
背景情况:
- 自免疫甲状腺炎 (AIT) 和乳腺癌之间的关系仍然不清楚,对潜在的介导因素的理解有限.
- 调查因果关系和媒介对于了解疾病途径和制定有针对性的干预措施至关重要.
研究的目的:
- 调查自身免疫性甲状腺炎 (AIT) 与乳腺癌之间的潜在因果关系.
- 确定AIT与乳腺癌关系中的潜在调解因素,包括代谢物和肠道微生物群.
主要方法:
- 利用采用全基因组协会研究 (GWAS) 数据的双向门德尔随机化 (MR) 分析.
- 使用单核酸多态 (SNP) 构建了仪器变量,其显著性值为p < 1.0 × 10−5.
- 逆方差加权 (IVW) 方法是主要的分析方法,对代谢物和肠道微生物群数据进行单因子和多因子MR分析.
主要成果:
- 发现自身免疫性甲状腺炎 (AIT) 显著增加患乳腺癌的风险 (OR > 1,P < 0.05).
- 在相反的方向 (乳腺癌与AIT) 中没有观察到显著的因果关系.
- 确定7-甲基丁是显著的调解剂,显示与AIT和乳腺癌的因果关系,而没有发现肠道微生物组调解剂.
结论:
- 自身免疫性甲状腺炎 (AIT) 与乳腺癌的风险增加有关.
- 7-甲基丁作为从AIT到乳腺癌的途径中的重要调解者.
- 根据这项分析,肠道微生物组似乎不会调解AIT和乳腺癌之间的关系.

Autoimmune Disorders
678
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Synthesis and Regulation of Thyroid Hormones
5.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
