Abstract
腫瘤微環境(TME)在促進癌症進展中發揮著至關重要的作用。
膠原蛋白是 TME 內細胞外基質(ECM)的主要成分。
受體酪胺酸激酶 Discoidin 結構域受體 1 (DDR1)是一種膠原蛋白受體,
可在膠原蛋白結合時被激活,隨後被細胞膜上的金屬酶 ADAM10 所裂解。
我們先前的研究顯示COL1/DDR1訊號軸有助於膀胱腫瘤的浸潤和遠端肺轉
移[1]。在目前的研究中,我們發現 I 型膠原蛋白(COL1)治療中下調
Ca2+ 依賴性膜結合蛋白-膜聯蛋白 A6 (ANXA6) 。ANXA6 已被證明是
一種多功能支架蛋白,可以與磷脂膜和各種訊號蛋白相互作用,從而
介導各種腫瘤進展機制。在本研究中顯示在膠原蛋白處理下 ANXA6
的蛋白質穩定性受到 DDR1 在細胞膜上完整性影響而下降,並非受到
膠原蛋白活化 DDR1 的活性後而改變,進一步發現 ANXA6 在膠原蛋
白腫瘤微環境下恢復其表現量會降低細胞增殖、遷移及抗藥性 ,以上
結果說明 ANXA6 在膀胱癌中可能是作為腫瘤抑制基因的角色 。此外
還發現降低ANXA6的表現造成細胞內鈣離子濃度的增加並誘導自噬
作用,並初步確定是膠原蛋白賦予細胞抗藥性的因素。
