Diabetes mellitus is a metabolic disorder associated with various complications encompassing male reproductive dysfunction. The present study aimed to investigate the therapeutic potential of biologically active seed oil (LSO) against the testicular dysfunction associated with streptozotocin (STZ)-induced diabetes. Male adults (n = 24) were divided into four groups: control, LSO-administered, diabetic (D), and LSO-treated diabetic (D+LSO) groups. LSO was extracted from seeds, and its chemical composition was determined using GC-MS. Serum testosterone levels, testicular enzymatic antioxidants (catalase (CAT) and superoxide dismutase (SOD)), an oxidative stress (OS) biomarker, malondialdehyde (MDA), pro-inflammatory markers (NF-kB, IL-1, IL-6, and TNF-α), and the expression level of NF-kB were assessed. In addition, histopathological changes were evaluated in testicular tissues. The results obtained showed that the chemical composition of LSO indicated its enrichment mainly with γ-tocopherol (62.1%), followed by 2-methylhexacosane (8.12%), butylated hydroxytoluene (8.04%), 10-Methylnonadecane (4.81%), and δ-tocopherol (3.91%). Moreover, LSO administration in the D+LSO mice significantly increased testosterone levels and ameliorated the observed testicular oxidative damage, inflammatory response, and reduced NF-kB expression compared to the diabetic mice. Biochemical and molecular analyses confirmed the histological results. In conclusion, LSO may prevent the progression of diabetes-induced impairment in the testes through inhibition of the OS- and NF-kB-mediated inflammatory response.
糖尿病是一种代谢紊乱疾病,与多种并发症有关,包括男性生殖功能障碍。本研究旨在探讨生物活性种子油(LSO)治疗链脲佐菌素(STZ)诱导的糖尿病相关睾丸功能障碍的潜力。雄性成年(n = 24)分为四组:对照组、LSO 给药组、糖尿病组(D)和 LSO 治疗糖尿病组(D+LSO)。从 种子中提取 LSO,并使用 GC-MS 确定其化学成分。测定血清睾酮水平、睾丸酶抗氧化剂(过氧化氢酶(CAT)和超氧化物歧化酶(SOD))、氧化应激(OS)生物标志物丙二醛(MDA)、促炎标志物(NF-kB、IL-1、IL-6 和 TNF-α)和 NF-kB 的表达水平。此外,评估睾丸组织的组织病理学变化。结果表明,LSO 的化学成分表明其主要富含γ-生育酚(62.1%),其次是 2-甲基二十六烷(8.12%)、丁基化羟基甲苯(8.04%)、10-甲基十九烷(4.81%)和δ-生育酚(3.91%)。此外,与糖尿病小鼠相比,D+LSO 组的 LSO 给药显著增加了睾酮水平,并改善了观察到的睾丸氧化损伤、炎症反应和 NF-kB 表达降低。生化和分子分析证实了组织学结果。总之,LSO 可能通过抑制 OS 和 NF-kB 介导的炎症反应来预防糖尿病引起的睾丸损伤的进展。
