MCAM
黑色素瘤細胞黏附分子（MCAM），又稱CD146或MUC18，是一種跨膜糖蛋白，屬于免疫球蛋白超家族成員。它廣泛表達于內皮細胞、黑色素瘤及多種實體瘤細胞表面，通過介導細胞間黏附、調控血管生成和腫瘤微環境重塑參與疾病進程。MCAM與Wnt/β-catenin、PI3K/AKT等關鍵通路存在交互作用，能夠增強腫瘤細胞的遷移侵襲能力，其在循環腫瘤細胞表面的高表達被認為是癌癥轉移的重要標志。
臨床上，MCAM的異常表達與黑色素瘤、三陰性乳腺癌、肝癌等多種惡性腫瘤的進展及不良預后顯著相關。近年來針對該靶點的藥物開發取得進展，例如人源化單抗ABX-MA1已進入針對轉移性黑色素瘤的Ⅰ期臨床試驗，其通過阻斷MCAM介導的血管新生抑制腫瘤生長。基于MCAM的CAR-T細胞療法在動物模型中顯示出抗胰腺癌活性，但需進一步驗證其臨床安全性。該靶點同時涉及多發性硬化癥等自身免疫疾病，相關抑制劑研究為跨領域治療提供了新思路。

IHC image of CSB-RA013563A0HU diluted at 1:100 and staining in paraffin-embedded human breast cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of U251 cells with CSB-RA013563A0HU at 1:37,counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃.The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG (H+L).
Overlay histogram showing A375 cells stained with CSB-RA013563A0HU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then permeabilized with 0.3% Triton X-100 for 2 min. The cells were then incubated in 1x PBS /10% normal goat serum to block non-specific protein-protein interactions followed by primary antibody for 1 h at 4℃.The secondary antibody used was FITC goat anti-rabbit IgG (H+L) at 1/200 dilution for 1 h at 4℃. Control antibody (green line) was used under the same conditions. Acquisition of >10,000 events was performed.
