Singapore scientists discover new drug targets for aggressive breast cancer | Science Codex

Posted: July 27, 2013 in Uncategorized

The scientists discovered that a protein tyrosine phosphatase, called UBASH3B, is overexpressed in one third of TNBC patients. UBASH3B controls the activity of an important breast cancer gene. The researchers found that deleting this gene expression markedly inhibits TNBC cell invasive growth and lung metastasis in a mouse model. They also showed that patients with TNBC tumours that have high levels of UBASH3B tend to be more likely to have early recurrence and metastasis.

Lead author Dr Qiang Yu said, “The identification of target genes is always the most crucial first step towards treating a disease. It is heartening to know that UBASH3B is an important element of the pro-invasive gene network and targeting UBASH3B not only inhibits TNBC invasive growth, but also significantly reduces metastasis.”
