PubMedPubMed 产品介绍Monoamine oxidase (MAO) is an enzyme of the mitochondrial outer membrane and catalyzes the oxidative deamination of biogenic amines throughout the body (1). MAO is critical in the neuronal metabolism of catecholamine and indolamine transmitters (2). Cultured skin fibroblasts show both MAO-A and MAO-B and both MAOs differ in molecular structure (1). MAO-A, the primary type in fibroblasts, preferentially degrades serotonin and norepinephrine (3). Only MAO-B is present in platelets and only MAO-A is present in trophoblasts (1). MAO-B, the primary type found not only in platelets but also in the brain of man and other primates, preferentially degrades phenylethylamine and benzylamine (3). MAO has been of particular interest to psychiatry and genetics because of the suggestion that low activity is a ‘genetic marker’ for schizophrenia (4). The genes which encode MAO-A and MAO-B map to human chromosome Xp11.23 (5). 靶点与功能
MUC2(Mucin-2)是凝胶形成型粘蛋白家族成员,核心功能与研究价值包括: 肠道屏障保护:由杯状细胞分泌,通过N端三聚化和C端二聚化形成黏液凝胶层(80%成分为O-糖链),物理隔离肠道菌群与上皮细胞(敲除MUC2导致小鼠自发性结肠炎); 肿瘤标志物:结直肠癌中MUC2表达下调与肿瘤侵袭深度正相关(Ⅲ/Ⅳ期患者MUC2阴性率达62%),可作为预后不良的独立指标; 炎症调控:黏液层完整性破坏(如溃疡性结肠炎)导致菌群易位,通过TLR4/NF-κB通路诱发慢性炎症。 实验操作关键要点
IHC-P肠道组织染色: 抗原修复:柠檬酸盐缓冲液(pH6.0)微波修复20分钟(石蜡切片),杯状细胞胞质呈棕黄色颗粒状阳性; 阳性对照:正常结肠黏膜(隐窝底部杯状细胞强阳性),结直肠癌组织中阳性信号减弱或缺失; 注意事项:避免使用胃组织作为阴性对照(MUC5AC表达可能交叉反应)。 WB检测(结肠组织裂解液): 样本处理:使用含蛋白酶抑制剂(1mM PMSF) 的RIPA裂解液(添加1% NP-40增强溶解度),冰上裂解40分钟; 电泳条件:4-12%梯度SDS-PAGE凝胶,恒压80V浓缩胶、100V分离胶,电泳180分钟; 结果特征:高分子量弥散条带(400-600kDa),糖基化程度高的样本条带迁移更慢。 IF黏液层结构观察: 与E-钙粘蛋白抗体共染,MUC2(绿色,黏液层)与E-钙粘蛋白(红色,上皮细胞)形成清晰的“黏液-上皮”界面; 样本制备:结肠组织冷冻切片(厚度8μm),4%多聚甲醛固定10分钟,0.3% Triton X-100透化15分钟。 公司正在出售的产品
