Epithelial cells and most adherent normal cells rely on adhesion-dependent,
integrin-mediated survival signals from the extracellular matrix (ECM) to
survive. When these cells are deprived of adhesion to the ECM, they undergo a
specific form of apoptosis termed "anoikis." In contrast, malignant cells have
attained mechanisms to enable them to survive in the absence of adhesion and are
considered anchorage-independent. This review will focus on the biological
function of the Bcl2-inhibitor of transcription (Bit1) protein in the anoikis
process, the underlying molecular mechanism of Bit1 apoptotic function, and its
role in tumor metastasis.
