Abstract
非小細胞肺癌(NSCLC)是最常見的肺癌類型,也是全球導致死亡的主要原因。NSCLC 預後不佳,且常對傳統化療產生耐藥性,這突顯了有效治療方案的迫切需求。甲狀腺激素去胺類似物 tetrac 及其奈米衍生物 NDAT 已被證明對多種癌症具有抗增殖作用。另一方面,馬海綿屬(Hippospongia sp.)中最豐富的次級代謝產物 heteronemin 對幾種類型的腫瘤細胞表現出強效的細胞毒活性。本研究評估了 heteronemin 和 tetrac 衍生物對兩種 NSCLC 細胞株 A549 和 H1299 的抗腫瘤效力。Heteronemin 和 tetrac 衍生物的聯合治療顯示出協同的抗增殖效果,並顯著調節了 A549 細胞中的 ERK1/2 和 STAT3 途徑,以及 H1299 細胞中的ERK1/2 途徑。聯合治療通過 caspase 途徑在 A549 細胞中誘導凋亡,並通過抑制 CCND1 和 PCNA 在 H1299 細胞中促進細胞週期停滯。這些發現表明,heteronemin 和 tetrac 的聯合使用可能通過抑制 NSCLC 細胞增殖所必需的信號途徑,為 NSCLC 患者提供了一種有希望且潛在的治療策略。
