Overexpression of Twist, a highly conserved basic helix-loop-helix transcription
factor, is associated with epithelial-mesenchymal transition (EMT) and predicts
poor prognosis in various kinds of cancers, including breast cancer. In order to
further clarify Twist's role in breast cancer, we detected Twist expression in
breast cancer tissues by immunohistochemistry. Twist expression was observed in
54% (220/408) of breast cancer patients and was positively associated with tumor
size, Ki67, VEGF-C and HER2 expression. Conversely, Twist was negatively
associated with estrogen receptor (ER), progesterone receptor (PgR) and
E-cadherin expression. Patients with Twist expression had a poorer prognosis for
30-month disease free survival (DFS) (82.9%) than patients with negative Twist
(92.3%). Overexpression of Twist led to dramatic changes in cellular morphology,
proliferation, migratory/invasive capability, and expression of EMT-related
biomarkers in breast cancer cells. Moreover, we show that Twist serves as a
driver of tumorigenesis, as well as an inducer of EMT, at least in part, through
activation of the Akt and extracellular signal-regulated protein kinase (ERK)
pathways which are critical for Twist-mediated EMT. Our results demonstrate that
Twist expression is an important prognostic factor in breast cancer patients.
