- **作者**: Watson, M.A., et al.
- **摘要**: 该研究首次克隆并鉴定了Mammaglobin基因，证实其在乳腺癌组织中的高特异性表达。研究表明，Mammaglobin抗体在免疫组化(IHC)中可作为乳腺癌(尤其是转移性病灶)的敏感标记物，显著优于传统标志物如GCDFP-15.
2. **《Mammaglobin-A as a diagnostic marker in metastatic breast carcinoma》**
- **作者**: Grunewald, K., et al.
- **摘要**: 通过分析200例转移性乳腺癌样本，研究发现Mammaglobin-A抗体在淋巴结和体液转移灶检测中敏感性达75%，特异性超过95%。其与GATA3联用可提高诊断准确性，支持其在临床病理学中的关键作用。
3. **《Comparative analysis of Mammaglobin and GCDFP-15 expression in triple-negative breast cancers》**
- **作者**: Bhargava, R., et al.
- **摘要**: 对比Mammaglobin与GCDFP-15在三阴性乳腺癌中的表达，发现Mammaglobin抗体在约60%病例中呈阳性，而GCDFP-15仅30%。研究建议将Mammaglobin纳入常规诊断组合，以改善亚型分类和治疗靶向策略。

Mammaglobin antibody is a valuable tool in diagnostic and research settings, primarily targeting the Mammaglobin-A (SCGB2A2) protein, a member of the uteroglobin family. Mammaglobin-A is predominantly expressed in mammary gland tissue and is overexpressed in 40–80% of breast cancers, making it a promising tumor-specific biomarker. Its restricted expression in healthy tissues enhances its diagnostic utility compared to broader markers like gross cystic disease fluid protein-15 (GCDFP-15).
Mammaglobin antibodies are widely used in immunohistochemistry (IHC) to detect metastatic breast cancer cells, particularly in lymph nodes or distant sites. They aid in distinguishing breast-origin adenocarcinomas from other malignancies, such as lung or ovarian cancers. Structurally, Mammaglobin-A often forms heterodimers with lipophilin B, and antibodies targeting specific epitopes improve detection sensitivity in clinical assays.
In research, Mammaglobin antibodies facilitate studies on breast cancer progression, minimal residual disease monitoring, and circulating tumor cell identification. They also hold therapeutic potential, with investigations into Mammaglobin-directed vaccines and CAR-T cell therapies.
However, limitations exist: Mammaglobin-A expression varies across breast cancer subtypes (e.g., higher in estrogen receptor-positive and invasive lobular carcinomas) and may be absent in some cases, necessitating complementary markers. Despite this, its specificity solidifies Mammaglobin antibodies as critical reagents in breast cancer diagnostics and research.
