Abstract :

Hexastatin is a known endogenous angioinhibitor molecule derived from alpha6 chain non-collagenous (NC1) domain of Type IV collagen, where as its angioinhibitory mechanism(s) is not yet known clearly. Here in the study, we have cloned hexastatin in pET22b (+) vector and expressed in E. Coli. Soluble and biologically active hexastatin was purified using different affinity and size exclusion chromatographies and studied its pro-apoptotic activities in-vitro using endothelial cells. Our preliminary in-vitro studies demonstrate that hexastatin inhibiting VEGF mediated endothelial cell proliferation, migration and tube formation. In addition, we have identified that hexastatin promoting endothelial cell apoptosis by activating FasL and its mediated downstream apoptotic cascade activation.
