brain metastasis
|
| Organism |
Homo sapiens |
| Characteristics |
disease state: brain metastatic breast cancer
tissue: brain metastasis
er status: ER+
her2 status: Her2+
age: 52.8 yr

| Extracted molecule |
total RNA |
| Extraction protocol |
4,000–5,000 malignant epithelial cells were procured by laser capture microdissection using a PixCell IIe system (Molecular Devices, Mountain View, CA, USA) as described in PubMed ID: 19187537. Total RNA was isolated from captured cells using the PicoPure RNA isolation kit (Molecular Devices), then amplified by T7 RNA amplification (RiboAmp; Molecular Devices).
