PLAUR
尿激酶型纤溶酶原激活物受体(PLAUR,又称uPAR或CD87)是一种锚定于细胞膜表面的糖蛋白受体,其核心功能是通过与尿激酶(uPA)结合,激活纤溶酶原转化为纤溶酶,进而触发细胞外基质降解酶类的级联反应。这一过程在组织重塑、伤口愈合中起关键作用,但也被发现与恶性肿瘤的侵袭转移密切相关。临床研究显示,PLAUR在乳腺癌、结直肠癌等多种实体瘤中高表达,其水平升高常提示患者预后不良。该受体还能与整合素等跨膜蛋白协同调控细胞迁移,参与动脉粥样硬化斑块形成及类风湿性关节炎的病理进程。
近年来针对PLAUR的药物开发聚焦于阻断uPA-uPAR相互作用,例如单抗类药物ATN-658已在动物模型中显著抑制肿瘤转移。小分子抑制剂如upain-1通过干扰受体二聚化降低癌细胞侵袭能力,目前处于临床前研究阶段。部分联合治疗方案尝试将uPAR靶向药物与传统化疗联用,初步数据显示可增强抗肿瘤效果并减少耐药性,但尚未进入三期临床试验。

Immunofluorescence staining of hela cell with CSB-RA018122MA1HU at 1:30, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG(H+L).

Overlay Peak curve showing Hela cells surface stained with CSB-RA018122MA1HU (red line) at 1:100. Then 10% normal goat serum was Incubated to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 45 min at 4°C. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,026 events was performed.
