概括

盐诱导性激酶2和3 (SIK2和SIK3) 在女性生育中起到截然不同的作用. SIK2促进卵泡发育,而SIK3对卵巢功能和生育至关重要.

科学领域:

生殖生物学生殖生物学
分子内分泌学分子内分泌学
细胞生物学细胞生物学

背景情况:

盐诱导性激酶 (SIK) 是一种涉及各种细胞过程的氨酸/氨酸激酶.
SIK被认为是女性生殖功能的关键调节者.
之前的研究表明SIK2和SIK3在女性生育中的作用相反.

研究的目的:

研究SIK2和SIK3在粒状细胞 (GCs) 中对卵泡发育和女性生育能力的不同作用.
阐明SIK2和SIK3不同调节卵巢功能的分子机制.

主要方法:

产生特定于颗粒细胞的SIK2和SIK3敲击小鼠模型 (SIK2GCKD和SIK3GCKD).
评估生育能力,子大小,以及对淋巴激素刺激的反应.
对血清雌激醇水平,GC基因表达 (Cyp11a1,Cyp19a1,StAR),卵细胞排卵和卵泡计数的分析.

主要成果:

SIK3GCKD小鼠表现出不孕症和减少 litter 尺寸,而SIK2GCKD小鼠表现出正常生育能力.
SIK2GCKD小鼠表现出增强的雌激素产量和卵细胞排卵后的淋巴激素刺激.
SIK3GCKD小鼠表现出雌激素的降低,毛囊发育受损,毛囊前的增加,以及改变的GC亡/增殖.

结论:

SIK2和SIK3对颗粒细胞功能,毛囊生长和女性整体生育能力产生差异性和相反的影响.
准SIK2或SIK3为不孕症治疗或新型避孕药开发提供了潜在的治疗策略.

关键词:

这就是SIK2的意义.这就是SIK3的意义.女性生育能力女性生育能力颗粒状细胞是颗粒状细胞.卵巢卵巢是一个卵巢.

Feedback Regulation of Calcium Concentration

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
