These conditions are associated with increased risk of cardiovascular disease the leading cause of death. Therefore it is important to understand the molecular basis underlying obesity and related metabolic diseases in order to develop effective preventive and therapeutic approaches against these conditions. Recently a family of proteins structurally similar to the angiogenic-regulating factors known as angiopoietins was identified and designated angiopoietin-like proteins ANGPTLs . Encoded by seven genes ANGPTL1-7 all possess an N-terminal coiled-coil domain and a C-terminal fibrinogen-like domain both characteristic of angiopoietins. ANGPTLs do not bind to either the angiopoietin receptor Tie2 or the related protein Tiel indicating that these ligands function differently from angiopoietins. Like angiopoietins some ANGPTLs potently regulate angiogenesis but ANGPTL3 -4 and ANG-PTL6 angiopoietin-related growth factor AGF directly .
