Excerpt
Myoepithelial cells (MEC) are essential to the maintenance of normal breast function, and loss of normal MEC function is commonly associated with breast cancer. Most established invasive breast carcinomas develop through an in situ phase known as ductal carcinoma in situ (DCIS). We have identified up-regulation of β6 integrin on MEC in a subset of DCIS. Normal MEC exhibit potent tumour suppressor function, but it is not clear whether this is compromised in DCIS. The aim of the present study is to investigate the effect of β6 expression on myoepithelial tumour suppressor function. …
