- 生物化学 生物化学
背景情况:
- 西斯丁 (CDDP) 是一种重要的化疗药物,但导致卵巢毒性,限制了女性的使用.
- 氧化应激 (OS) 和炎症是西斯普拉丁诱导的卵巢毒性的关键机制.
- 香酸 (VA) 是一种天然化合物,具有强大的抗氧化特性.
研究的目的:
- 首次在大鼠模型中研究香草酸 (VA) 对西斯 (CDDP) 诱导的卵巢损伤的保护作用.
- 阐明VA治疗作用的潜在机制,重点关注氧化应激,炎症,内质网膜应激 (ERS) 和亡.
- 评估VA对生殖激素水平的影响,在CDDP诱导的卵巢毒性背景下.
主要方法:
- 在雌性大鼠中,使用单剂西斯丁 (5 mg/kg) 诱导了卵巢毒性.
- 大鼠接受了三天的香草酸 (5和10毫克/公斤) 治疗.
- 在卵巢组织中测量了氧化应激,炎症,内质网膜应激和亡的生化标志物;在血清中量化了生殖激素.
主要成果:

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
202
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Electron Transport Chain: Complex I and II
14.5K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
