Resveratrol modulates MED28 (Magicin/EG-1) expression and inhibits epidermal growth factor (EGF)-induced migration in MDA-MB-231 human breast cancer cells.
AnxA1 promotes metastasis formation by enhancing TGFbeta/Smad signaling and actin reorganization, which facilitates an EMT-like switch, thereby allowing efficient cell migration and invasion of metastatic breast cancer cells.
Treatment of mice with resveratrol and TRAIL alone inhibited angiogenesis (as demonstrated by reduced number of blood vessels, and VEGF and VEGFR2 positive cells) and markers of metastasis (MMP-2 and MMP-9).

Matrix metalloproteinase-2 (MMP-2) is a key enzyme in the degradation of extracellular matrices and its expression has been dysregulated in breast cancer invasion and metastasis.
COX-2 over-expression can up-regulate the expression of VEGF-C. VEGF-C might promote lymph node metastasis by a lymph-angiogenic pathway, then affect the prognosis of the patients with breast cancer.
In patients with Dukes'C colorectal cancer who underwent curative surgical resection of the primary tumour, followed by 5-FU-based adjuvant chemotherapy, p53 mutation status as assessed by gene sequencing is a significant predictor of overall and metastasis-free survival.
Also, the serum HER2 level was significantly higher in bone metastatic cancer patients (14.3 +/- 6.3 ng/mL) than in non-metastatic patients (T2: 11.9 +/- 2.3 ng/mL, P = 0.003; T3: 12.2 +/- 2.8 ng/mL, P = 0.011).
The COX-2 inhibitors, NS-398 and nimesulide, significantly suppressed bone metastases with decreased osteoclast number and increased apoptosis in MDA-MB-231 cells.
These findings demonstrate that MALAT1 is a metastasis-suppressing lncRNA rather than a metastasis promoter in breast cancer, calling for rectification of the model for this highly abundant and conserved lncRNA.

Tumor genomic complexity increases with EGFR-inhibitor treatment, and co-occurring alterations in CTNNB1 and PIK3CA exhibit nonredundant functions that cooperatively promote tumor metastasis or limit EGFR-inhibitor response.
Our data provide insights into the mechanistic regulation and linkage of the ROR1-HER3 and Hippo-YAP pathway in a cancer-specific context, and also imply valuable therapeutic targets for bone metastasis and possible therapy-resistant tumours.
