概括
黄素激素 (LH) β子单元基因和激素水平的遗传变异不能预测患有多囊性卵巢综合征 (PCOS) 的女性的受控卵巢过度刺激 (COH) 反应. 这些因素并不是本研究组中COH结果的有效临床指标.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 人类遗传学 人类遗传学
- 在体外受精 (IVF)
背景情况:
- 黄素激素 (LH) β子单元基因中的遗传多态性与体外受精 (IVF) 患者的受控卵巢过度刺激 (COH) 反应有关.
- 特定的变异 (rs1800447和rs34349826) 可能会影响雄激素的产生,可能会影响卵泡发育和卵巢反应.
研究的目的:
- 评估LHβ亚单元单核酸多形态 (SNP) 的临床意义 (rs1800447和rs34349826).
- 评估的预测价值,性激素结合型全球蛋白 (SHBG) 和自由的指数,用于COH响应在患有多囊性卵巢综合征 (PCOS) 的女性.
- 专门研究这些标记物在接受COH.COH.治疗的正常雄激素PCOS妇女身上.
主要方法:
- 一个嵌套的病例控制研究,涉及122名妇女PCOS在莫鲁拉试管婴儿雅加达诊所.
- 使用桑格测序对LHβ亚单元SNP (rs1800447和rs34349826) 的基因定型.
- 测量和SHBG水平以计算自由指数;回顾分组为低响应体 (<8个卵细胞) 和标准/高响应体 (≥8个卵细胞) 组.
主要成果:
- 在rs1800447和rs34349826两种LHβ子单元基因中都发现了一种新的自动传播 (AT) 变异.
- 在低响应组和常态/高响应组 (P > 0.05) 之间,对异合体基因型 (AT 和 AG) 的比例没有发现显著差异.
- 所有参与者表现出正常的雄激素水平 (,SHBG,自由指数),在各组之间没有发现显著差异 (P>0.05).
结论:
- 在正常雄激素PCOS女性中,LHβ基因SNP (rs1800447和rs34349826) 与COH反应没有显著的相关性.
- 水平,SHBG水平和自由指数是预测这种特定患者群体中COH反应的无效临床指标.
- 可能需要进一步的研究来确定可靠的COH预测结果在normoandrogenic PCOS患者的可靠预测.

Hormonal Control of the Ovarian Cycle
6.5K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Types of Hormones
83.1K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Combinatorial Gene Control
9.5K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Cell Specific Gene Expression
16.3K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Target Cell Response to Hormones
5.2K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
