概括

线粒体DNA (mtDNA) R组可能会保护台湾妇女免受卵巢反应减弱 (DOR) 和不孕症. 与其他群体不同,这个单双组显示出稳定的线粒体相关标志物和随着年龄增长的卵细胞产量.

科学领域:

生殖生物学生殖生物学
遗传学遗传学是一个
线粒体DNA研究的研究.

背景情况:

卵巢反应减弱 (DOR) 是女性生育能力的一个重大问题.
线粒体功能障碍与衰老和卵巢储备减少有关.
线粒体DNA (mtDNA) 单基组在卵巢反应中的作用尚未完全理解.

研究的目的:

调查 mtDNA 单基因组与台湾女性卵巢反应减弱 (DOR) 之间的关联.
探索不同mtDNA单基组内的年龄,线粒体相关标记物和卵巢反应之间的关系.

主要方法:

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Oogenesis

Oogenesis

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...

Ovarian Cycle

Ovarian Cycle

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...
