Abstract

Calcium ions (Ca2+) regulate cell proliferation and differentiation and participate in various physiological activities of cells. The calcium transfer protein inositol 1,4,5-triphosphate receptor (IP3R), located between the endoplasmic reticulum (ER) and mitochondria, plays an important role in regulating Ca2+ levels. However, the mechanism by which IP3R1 affects porcine meiotic progression and embryonic development remains unclear. We established a model in porcine oocytes using siRNA-mediated knockdown of IP3R1 to investigate the effects of IP3R1 on porcine oocyte meiotic progression and embryonic development. The results indicated that a decrease in IP3R1 expression significantly enhanced the interaction between the ER and mitochondria. Additionally, the interaction between the ER and the mitochondrial Ca2+ ([Ca2+]m) transport network protein IP3R1-GRP75-VDAC1 was disrupted. The results of the Duolink II in situ proximity ligation assay (PLA) revealed a weakened pairwise interaction between IP3R1-GRP75 and VDAC1 and a significantly increased interaction between GRP75 and VDAC1 after IP3R1 interference, resulting in the accumulation of large amounts of [Ca2+]m. These changes led to mitochondrial oxidative stress, increased the levels of reactive oxygen species (ROS) and reduced ATP production, which hindered the maturation and late development of porcine oocytes and induced apoptosis. Nevertheless, after treat with [Ca2+]m chelating agent ruthenium red (RR) or ROS scavenger N-acetylcysteine (NAC), the oocytes developmental abnormalities, oxidative stress and apoptosis caused by Ca2+ overload were improved. In conclusion, our results indicated IP3R1 is required for meiotic progression and embryonic development by regulating mitochondrial calcium and oxidative damage.

通过调节线粒体钙和氧化损伤,减数分裂过程和胚胎发育需要 IP3R1
钙离子(Ca2+)调节细胞的增殖和分化,并参与细胞的各种生理活动。位于内质网(ER)和线粒体之间的钙转移蛋白肌醇 1,4,5-三磷酸受体(IP3R)在调节 Ca2+ 水平方面发挥着重要作用。然而,IP3R1 影响猪减数分裂进程和胚胎发育的机制仍不清楚。我们利用 siRNA 介导的 IP3R1 基因敲除建立了猪卵母细胞模型,研究 IP3R1 对猪卵母细胞减数分裂进程和胚胎发育的影响。结果表明,降低 IP3R1 的表达能显著增强 ER 与线粒体之间的相互作用。此外,ER 与线粒体 Ca2+ ([Ca2+]m)转运网络蛋白 IP3R1-GRP75-VDAC1 之间的相互作用也被破坏。Duolink II 原位近接试验(PLA)的结果显示,干扰 IP3R1 后,IP3R1-GRP75 和 VDAC1 之间的配对相互作用减弱,GRP75 和 VDAC1 之间的相互作用显著增强,导致大量[Ca2+]m 的积累。这些变化导致线粒体氧化应激,增加了活性氧(ROS)的水平,减少了 ATP 的产生,阻碍了猪卵母细胞的成熟和后期发育,诱导了细胞凋亡。然而,用[Ca2+]m螯合剂钌红(RR)或ROS清除剂N-乙酰半胱氨酸(NAC)处理后,Ca2+超载引起的卵母细胞发育异常、氧化应激和细胞凋亡得到了改善。总之,我们的研究结果表明,IP3R1 通过调节线粒体钙和氧化损伤,是减数分裂过程和胚胎发育所必需的。
