Abstract
Hox geni se neprestano javljaju kao ključni čimbenici u embrionalnom razvitku i evoluciji. Zajedno s drugim genima čine signalne mreže, djelujući kao modulatori ili pak sudjeluju u formiranju novih struktura. Specifičnost i funkcija hox gena ovisi o njihovoj regulaciji koja je višeslojna i kompleksna. Glavni cilj ovoga rada bio je predstaviti uloge hox gena kod embriogeneze, te ukazati na osnovne aspekte regulacije. Za potpuno razumijevanje uloga i specifičnosti hox gena potrebno je još mnogo istraživanja posebice kod dešifriranja mreža hox gena i njihove regulacije, što bi olakšalo liječenje bolesti povezanih s hox genima, i omogućilo bolje razumijevanje uloge hox gena u evoluciji.Hox genes keep on occuring as key elements in embryogenesis and evolution. Together with other genes they form signaling networks, acting as modulators or participating in the formation of new structures. Specificity and function of hox genes depend on their regulation which is multilayered and complex. The main goal of this review was to present the roles of hox genes during embryogenesis, and to point out the basic aspects of regulation. More research is needed to completely understand the roles and specificity of hox genes, especially in deciphering hox networks and their regulation, which would make it easier to cure hox-related diseases, and allow better understanding of the roles of hox genes in evolution
