概括
这项研究研究了性别激素和生殖因素在差异化甲状腺癌 (DTC) 风险. 虽然发现了一些关联,但没有确立强烈的因果关系,这表明需要对DTC性别差异进行进一步研究.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 遗传学 遗传学 是一个
背景情况:
- 分化甲状腺癌 (DTC) 影响女性的频率是男性的三倍.
- 这种DTC发病率的性别差异的生物学基础尚不清楚.
- 研究性激素和生殖因素的影响至关重要.
研究的目的:
- 探索性激素,生殖因素和差异化甲状腺癌 (DTC) 风险之间的潜在因果关系.
- 使用门德尔的随机化来评估这些关联,并考虑潜在的混因素.
主要方法:

- 使用全基因组关联研究 (GWAS) 对DTC,性激素和生殖因素的总结统计数据.
- 使用逆变量加权 (IVW) 和多变量MR (MVMR) 方法,对BMI和TSH进行调整.
主要成果:
- 在性激素结合球蛋白 (SHBG) 和DTC风险之间观察到一种积极的关联,在对TSH和BMI进行调整后,这种风险失去了意义.
- 在BMI调整后,生物可用的丸激素与DTC风险有边际显著的积极关联.
- 在绝经前女性的子宫纤维瘤和DTC之间发现了假定的因果关系.

Synthesis and Regulation of Thyroid Hormones
4.1K
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...

The Ratio of X Chromosome to Autosomes
8.4K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Functions of Thyroid Hormones
2.4K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Chromosomal Theory of Inheritance
52.6K
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Oogenesis
63.3K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Transducer Mechanism: Nuclear Receptors
1.2K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
