Abstract (english)
The objective of this study was to determine diff erential expression of TFF1, TFF2 and TFF3 genes and proteins in breast tumor subtypes. In addition, we investigated the correlation between TFF genes within tumor subgroups, and TFF genes with clinical and pathologic characteristics of the tumor. Study group included 122 patients with surgically removed breast tumors. Samples were investigated using qRT-PCR and immunohistochemistry. TFF1 and TFF3 genes and proteins were expressed in breast tumors, while the levels of TFF2 gene and protein expression were very low or undetectable. TFF1 was signifi cantly more expressed in benign tumors, while TFF3 was more expressed in malignant tumors. Gene and protein expression of both TFF1 and TFF3 was greater in lymph node-negative tumors, hormone positive tumors, tumors with moderate levels of Ki67 expression, and in grade II tumors. A strong positive correlation was found between TFF1 and TFF3 genes, and the expression of both negatively correlated with Ki67 and the level of tumor histologic diff erentiation. Our results suggest that TFF1 and TFF3, but not TFF2, may have a role in breast tumor pathogenesis and could be used in the assessment of tumor diff erentiation and malignancy.
Abstract (croatian)
Cilj ovoga istraživanja bio je utvrditi razlike u izražaju gena i proteina TFF1, TFF2 i TFF3 u različitim vrstama tumora dojke te ispitati korelacije između gena TFF i vrsta tumora te gena TFF i kliničko-patoloških karakteristika tumora. U studiju su bile uključene 122 ispitanice kojima je kirurški odstranjen tumor dojke. Uzorci su obrađeni metodom qRT-PCR i metodom imunohistokemije. Geni i proteini TFF1 i TFF3 bili su izraženi u tumorima dojke, dok izražaj gena i proteina TFF2 nije otkriven u tumorskom tkivu. TFF1 je bio izraženiji kod dobroćudnih tumora, dok je TFF3 bio izraženiji kod zloćudnih tumora. TFF1 i TFF3 su bili izraženiji u hormonski ovisnim tumorima, tumorima bez metastaza u limfnim čvorovima, tumorima s umjereno visokim izražajem Ki67 i umjereno diferenciranim tumorima. Jaka pozitivna korelacija uočena je između gena TFF1 i TFF3, a oba su negativno korelirala s faktorom Ki67 i stupnjem diferenciranosti tumora. Dobiveni rezultati pokazuju kako bi TFF1 i TFF3 mogli imati ulogu u patogenezi tumora dojke te bi se potencijalno mogli rabiti za određivanje tumorskog statusa i procjenu malignosti tumora.
