Abstract
Signals from the epidermal growth factor (EGF) receptor family are thought to combine with integrinโdependent adhesion to laminins to contribute to disease progression and metastasis in cancer. To date, little is known about the mechanisms by which these signals interact. Recently, we have shown that the colon cancer cell line LIM1215 secretes and adheres to lamininโ10 through multiple integrin receptors, and that EGF stimulates spreading and migration of these cells on the same substrate. Additionally lamininโ10/11 has been shown by immunohistochemistry to be present at the invasive edge of moderately differentiated colon cancers. To enable detailed structureโfunction studies to be undertaken, it is important to be able to rapidly obtain highly purified native lamininโ10 from bulk biological samples in reasonable yield. The development of a multidimensional micropurification scheme to achieve this is presented and compared with other reported methods for the purification of laminins.
