MCAM
黑色素瘤细胞黏附分子(MCAM),又称CD146或MUC18,是一种跨膜糖蛋白,属于免疫球蛋白超家族成员。它广泛表达于内皮细胞、黑色素瘤及多种实体瘤细胞表面,通过介导细胞间黏附、调控血管生成和肿瘤微环境重塑参与疾病进程。MCAM与Wnt/β-catenin、PI3K/AKT等关键通路存在交互作用,能够增强肿瘤细胞的迁移侵袭能力,其在循环肿瘤细胞表面的高表达被认为是癌症转移的重要标志。
临床上,MCAM的异常表达与黑色素瘤、三阴性乳腺癌、肝癌等多种恶性肿瘤的进展及不良预后显著相关。近年来针对该靶点的药物开发取得进展,例如人源化单抗ABX-MA1已进入针对转移性黑色素瘤的Ⅰ期临床试验,其通过阻断MCAM介导的血管新生抑制肿瘤生长。基于MCAM的CAR-T细胞疗法在动物模型中显示出抗胰腺癌活性,但需进一步验证其临床安全性。该靶点同时涉及多发性硬化症等自身免疫疾病,相关抑制剂研究为跨领域治疗提供了新思路。

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.
