COA 产品使用指南 技术支持

Spexin (Neuropeptide Q) 是甘丙肽受体 GAL2GAL3 的选择性激动剂,是具有神经递质/神经调节因子和内分泌因子作用的保守肽。Spexin 可通过中枢和外周双重作用发挥功能。Spexin 上调 Beclin 1 抑制过度自噬 (autophagy) 诱导的铁死亡 (ferroptosis),减少脂肪细胞对长链脂肪酸的摄取,并通过增加脂质氧化调节能量代谢 (如降低啮齿类动物的呼吸交换比)。Spexin 可改善 Doxorubicin hydrochloride (HY-15142) 诱导心脏毒性的心脏功能,保护线粒体膜电位,减少铁积累和脂质过氧化。Spexin 可用于肥胖及其相关代谢紊乱、心血管疾病 (如心肌保护) 和肿瘤化疗副作用的研究。

生物活性

Spexin (Neuropeptide Q) is a selective agonist of galanin receptors GAL2 and GAL3, and is a conserved peptide that functions as a neurotransmitter/neuromodulator and endocrine factor. Spexin can function through both central and peripheral actions. Spexin upregulates Beclin 1 to inhibit ferroptosis induced by excessive autophagy, reduces the uptake of long-chain fatty acids by adipocytes, and regulates energy metabolism by increasing lipid oxidation (e.g., reducing the respiratory exchange ratio in rodents). Spexin improves cardiac function in the Doxorubicin hydrochloride (HY-15142)-induced cardiotoxicity model, protects mitochondrial membrane potential, and reduces iron accumulation and lipid peroxidation. Spexin can be used to study obesity and its related metabolic disorders, cardiovascular diseases (e.g., cardioprotection), and side effects of tumor chemotherapy[1][2][3].

体外研究
(In Vitro)

Spexin (1 μM;24 h) 增加 Doxorubicin (HY-15142A) 处理的新生大鼠心肌细胞 (NRCs) 活力并减少凋亡,逆转线粒体膜电位丢失并上调 GPX4/SLC7A11[2]
Spexin (20 ng/mL;2 h) 抑制分离的小鼠脂肪细胞长链脂肪酸 (LCFA) 摄取[3]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

Cell Line: Neonatal rat cardiomyocytes (NRCs)
Concentration: 1 μM
Incubation Time: 24 h; with or without 0.5 μM Doxorubicin
Result: Showed a 35% increase in viability compared to Doxorubicin-treated controls, with reduced LDH release.
体内研究
(In Vivo)

Spexin (50 μg/kg;腹腔注射;每日一次;4 周) 改善 Doxorubicin hydrochloride (5 mg/kg/周;4 周;腹腔注射) 诱导的小鼠心脏毒性模型的心脏功能,降低氧化应激[2]
Spexin (35 μg/kg/天;皮下注射;19 天) 减少雄性 Sprague-Dawley 大鼠的食物摄入量和体重增加[3]
Spexin (25 μg/kg/天;腹腔注射;10 天) 可显著降小鼠低夜间呼吸交换率 (RER),并增加运动能力[3]
Spexin 在雌性大鼠的条件性味觉厌恶测试中,(70 μg/kg/天;腹腔注射;单剂量) 未引起厌恶效应[3]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6 male mice (8 weeks old, 20-25 g) with Doxorubicin-induced cardiotoxicity model[2]
Dosage: 50 μg/kg
Administration: Intraperitoneal injection (i.p.), daily for 4 weeks, starting 24 h after Doxorubicin hydrochloride injection (5 mg/kg/weeks, i.p., 4 weeks; with injectionson days 0, 7, 14 and 28)
Result: Cardiac Function: Echocardiography showed increased ejection fraction (EF) from 45 ± 5% to 58 ± 4% and fractional shortening (FS) from 22 ± 3% to 30 ± 3% in Spexin-treated group compared to doxorubicin control.
Oxidative Stress: Cardiac tissue showed reduced MDA levels (2.5 ± 0.3 nmol/mg protein vs. 3.8 ± 0.4 nmol/mg protein in control) and increased SOD activity (120 ± 10 U/mg protein vs. 90 ± 8 U/mg protein in control).
Histology: H&E staining revealed less myocardial damage and fibrosis in Spexin-treated hearts.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
