概括
这项研究发现,怀孕时有或没有白色体的妇女之间没有血蛋白差异. 然而,受孕方法显著改变了血蛋白质组,识别了潜在的先兆子的生物标志物.
科学领域:
- 生殖生物学和蛋白质组学
- 孕产妇和胎儿的医学
背景情况:
- 黄体缺失与妊娠前风险增加有关.
- 红色体的分泌产品可能会影响怀孕的结果.
- 黄体在孕前的作用背后的机制尚未完全理解.
研究的目的:
- 为了研究与没有白色体怀孕的妇女的血蛋白质组差异.
- 检查受孕模式和血蛋白质组之间的关系.
- 为了确定孕产前风险的潜在生物标志物.
主要方法:
- 血样本从12名参与者在三个怀孕阶段 (第1季度,第3季度,产后) 收集.
- 参与者包括无助受孕 (UC),人工循环冷胚胎移植 (AC FET) 和自然循环冷胚胎移植 (NC FET) 的妇女.
- 基于质谱的蛋白质组学分析了36个血样本,以根据黄体存在和受孕方法对蛋白质组进行比较.
主要成果:
- 在有或没有白色体的怀孕之间没有发现差异表达的血蛋白.
- 在所有时间点之间,在无助受孕 (UC) 和冷胚胎移植 (FET) 之间分别表达了15种蛋白质.
- 像PAPPA和ANG这样的改变蛋白与妊娠前有关;SERPINA7在UC内有所不同.
- 在AC FET和NC FET之间没有观察到显著的蛋白质差异.
结论:
- 怀孕方式,而不是黄体的存在,揭示了明显的血蛋白质组签名.
- 已识别的候选蛋白质需要进一步研究,作为潜在的产前的生物标志物.
- 建议进行更大的队列研究和替代蛋白质组技术进行验证.

Ovarian Cycle
3.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Gonadal and Placental Hormones
2.7K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Secretory Phase
2.0K
The secretory phase of the menstrual cycle, spanning from day 14 to 28 in a typical 28-day cycle, is a period of significant physiological changes in the female reproductive system. This phase commences immediately after ovulation and is characterized by the preparation of the endometrium for potential embryo implantation.
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...

Proliferative Phase
1.2K
The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...

Proteomics
9.2K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Fertilization
89.1K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
