Abstract
臨床常見治療癌症之化療藥物Cisplatin (CIS)造成睪丸功能障礙之副作用會影響男性生殖功能。睪丸內細胞因氧化壓力增加會促使發炎反應,細胞走向凋亡損傷,亦會發生精子生成異常,最終造成睪丸功能性受損。而L-半胱胺酸 (L-cysteine, CYS)因具有強大抗氧化、抗發炎等功效,但至今對男性生殖影響之相關機制研究尚未明確證實,故本研究目的為考慮臨床輔助治療之應用,以體內及體外模式探討CYS對CIS造成男性生殖損傷之相關改善效應。體外實驗利用TM3及TM4小鼠睪丸細胞株,以MTS試驗及結晶紫染色測定細胞存活率,以Western blot測定血睪障壁、發炎及細胞凋亡相關蛋白表現。結果顯示,CYS可顯著恢復CIS誘導TM3及TM4細胞存活率,並減少Caspase3、PARP、Bax凋亡相關蛋白表現,同時降低TM3細胞NLRP3及COX2發炎相關蛋白表現,且增加TM4細胞ZO-1結構蛋白表現。亦以CIS建立誘導睪丸損傷之動物模式,實驗期21天後,發現CYS可顯著降低睪丸組織及精子結構損傷,維持血清睪固酮濃度,恢復精子存活狀態,並且減少睪丸PARP蛋白表現。因此,本研究表明L-cysteine可改善Cisplatin對男性生殖之不利影響,顯示L-cysteine具有輔助臨床Cisplatin藥物治療下對男性生殖功能損傷之保護潛力。
