PURPOSE The present study was aimed to demonstrate the recuperative effect of nesfatin-1 on testicular dysfunction in the high-fat diet (HFD)/streptozotocin (STZ)-induced type-2 diabetes mellitus (T2DM) mice. METHOD AND RESULTS Three experimental groups were formed: (1) vehicle control (VC), (2) T2DM mice, (3) T2DM + nesf-1. The mice with blood glucose level higher than 300 mg/dL following HFD and a single dose of STZ were used for the experiment. The T2DM mice showed increases in body mass, blood glucose and insulin levels, reductions in spermatogenesis and steroidogenesis, production of antioxidative enzymes, and disturbed lipid profile. These alterations were all ameliorated by administration of nesfatin-1 at 20 μg/Kg BW for 15 days. Nesfatin-1 treatment also increased the production of testosterone (T), improved insulin sensitivity, and effectively ameliorated the testicular aberrations, and increased spermatogenesis and steroidogenesis. In addition, nesfatin-1 treatment upregulated the PCNA and Bcl2 expression and inhibited the caspase-3 and prohibitin expression in T2DM mice. Nesfatin-1 increased insulin receptor (IR) and GLUT8 expressions, and lactate production, the changes that further substantiate the increase of energy influx to the testis. CONCLUSION Altogether, the results suggest the ameliorative effect of nesfatin-1 against T2DM-associated testicular dysfunctions and improved insulin sensitivity along with promoting T production and fertility in T2DM mice.

Nesfatin-1 改善雄性小鼠 2 型糖尿病相关的生殖功能障碍。

目的 本研究旨在证明 nesfatin-1 对高脂饮食 (HFD)/链脲佐菌素 (STZ) 诱导的 2 型糖尿病 (T2DM) 小鼠睾丸功能障碍的恢复作用。方法与结果 形成三个实验组:(1)载体对照(VC),(2)T2DM小鼠,(3)T2DM+nesf-1。HFD后血糖水平高于300 mg/dL的小鼠和单剂量STZ用于实验。T2DM 小鼠的体重、血糖和胰岛素水平增加,精子生成和类固醇生成减少,抗氧化酶的产生和脂质分布紊乱。这些改变都通过以 20 μg/Kg BW 施用 nesfatin-1 15 天得到改善。Nesfatin-1 治疗还增加了睾酮 (T) 的产生,改善了胰岛素敏感性,有效改善睾丸畸变,增加精子生成和类固醇生成。此外,nesfatin-1 处理上调了 PCNA 和 Bcl2 的表达,并抑制了 T2DM 小鼠中 caspase-3 和抑制素的表达。Nesfatin-1 增加了胰岛素受体 (IR) 和 GLUT8 的表达,以及乳酸的产生,这些变化进一步证实了睾丸能量流入的增加。结论 总之,结果表明 nesfatin-1 对 T2DM 相关的睾丸功能障碍具有改善作用,并改善了胰岛素敏感性,同时促进了 T2DM 小鼠的 T 产生和生育能力。nesfatin-1 治疗上调 PCNA 和 Bcl2 表达,并抑制 T2DM 小鼠中 caspase-3 和抑制素的表达。Nesfatin-1 增加了胰岛素受体 (IR) 和 GLUT8 的表达,以及乳酸的产生,这些变化进一步证实了睾丸能量流入的增加。结论 总之,结果表明 nesfatin-1 对 T2DM 相关的睾丸功能障碍具有改善作用,并改善了胰岛素敏感性,同时促进了 T2DM 小鼠的 T 产生和生育能力。nesfatin-1 治疗上调 PCNA 和 Bcl2 表达,并抑制 T2DM 小鼠中 caspase-3 和抑制素的表达。Nesfatin-1 增加了胰岛素受体 (IR) 和 GLUT8 的表达,以及乳酸的产生,这些变化进一步证实了睾丸能量流入的增加。结论 总之,结果表明 nesfatin-1 对 T2DM 相关的睾丸功能障碍具有改善作用,并改善了胰岛素敏感性,同时促进了 T2DM 小鼠的 T 产生和生育能力。
