Acetylcholinesterase supports anchorage independence in colon cancer.

Various roles have been attributed to Acetylcholinesterase (AChE) in cancer. Evidence exists for a pro-apoptotic function, consistent with a protective role of AChE. Because other reports suggested that upregulated AChE in some tumors may control cell adhesion, we tested the effects of AChE on anchorage independence (an essential component of metastasis) of colon tumor cells.
