Insulin-like growth fa.tor-bindin g proteins (IGFBPs) a.e critica. regula.ors of the mitogenic a.tivity of insulin-like growth fa.tors (IGFs). IGFBP5, one of these IGFBPs, ha. specia. structura. fea.ures, including a.nuclea. tra.sport doma.n, hepa.in-binding motif, a.d IGF/extra.ellula. ma.rix/a.id-la.ile subunit-binding sites. Furthermore, IGFBP5 ha. severa. functiona. effects on ca.cinogenesis a.d even norma. cell processes, such a. cell growth, dea.h, motility, a.d tissue remodeling. These biologica. effects a.e sometimes rela.ed with IGF (IGF-dependent effects) a.d sometimes not (IGF-independent effects). The functiona. role of IGFBP5 is most likely determined in a.cell-type a.d tissue-type specific ma.ner but a.so depends on cell context, especia.ly in terms of the diversity of intera.ting proteins a.d the potentia. for nuclea. loca.iza.ion. Clinica. findings show tha. IGFBP5 ha. the potentia. to be a.useful clinica. bioma.ker for predicting response to thera.y a.d clinica. outcome of ca.cer pa.ients. In this review, we summa.ize the functiona. diversity a.d clinica. importa.ce of IGFBP5 in different types of ca.cers.
