概括
患有卵泡囊的奶牛显示出更高水平的Kisspeptin-10 (Kp-10) 和淋巴激素抑制激素 (GnIH). 这与卵巢囊中的Kp-10受体减少有关,这表明内分泌失衡.
科学领域:
- 兽医内分泌学 兽医内分泌学
- 牲畜中的生殖生物学.
背景情况:
- 毛囊囊 (FC) 是乳牛常见的内分泌疾病,影响生育能力.
- 下垂体-垂体-卵巢 (HPO) 轴在卵巢功能中起着至关重要的作用,并与FC发育有关.
研究的目的:
- 为了研究基斯佩普丁-10 (Kp-10) 和淋巴激素抑制激素 (GnIH) 在乳牛毛囊囊的病理生理学中的作用.
- 评估它们各自受体GPR54和GPR147在卵巢毛囊中的表达.
主要方法:
- 在体内对Kp-10,GNIH,化激素 (LH),雌激素 (E2) 和健康奶牛和患有FC的牛皮质醇进行激素分析.
- 使用基因表达分析在囊性和预排卵性毛囊中GPR54和GPR147分布的体外评估.
主要成果:
- 与健康对照群相比,在患有FC的奶牛中观察到Kp-10,GNIH,LH,E2和皮质醇的血清度显著增加.
- 与排卵前的卵泡相比,在卵泡囊中发现了减少的GPR54mRNA水平.
- 在任何类型的毛囊中都没有检测到GPR147受体的表达.
结论:
- 患有FC的奶牛血清Kp-10的升高可能导致GPR54的下调,导致囊的形成.
- 在HPO轴中观察到的内分泌失衡表明Kp-10和GNIH分泌模式的改变是毛囊囊的特征.

463
Folliculogenesis is the development of ovarian follicles, the specialized structures within the ovarian cortex where oogenesis, or egg development, occurs. This process is essential for female reproductive health and begins during fetal development when primordial follicles are formed. Each primordial follicle comprises a primary oocyte in the center, surrounded by a single layer of squamous pre-granulosa cells. These follicles remain dormant in late prophase I of meiosis until triggered by...

01:27Ovarian Cycle
900
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...
