Lysyl oxidase-like 2 promotes migration in noninvasive breast cancer cells but not in normal breast epithelial cells.

A growing number of studies indicate the importance of the lysyl oxidase family in the promotion of epithelial neoplasms towards their more aggressive forms. However, the role of individual family members in carcinoma progression has yet to be ascertained. In this study, we analyzed LOXL2 expression in malignantly transformed MCF-7 and normal MCF-10A mammary epithelial cell line clones stably transduced with LOXL2 in vitro, and in normal and cancerous breast tissue samples in vivo.
