Abstract
Pojam serumska cirkulirajuća DNA (cfDNA) odnosi se na cirkulirajuće DNA fragmente prisutne u krvi zdravih i oboljelih osoba. Trofoblast i maligni tumori dijele određene karakteristike, poput invazivnosti, sposobnosti metastaziranja i angiogeneze, zbog čega tkivo trofoblasta nazivamo i pseudomalignim tkivom. Stanice trofoblasta i malignih tumora otpuštaju specifične DNA fragmente u krv nazvane cirkulirajuća fetalna DNA (cffDNA) i cirkulirajuća tumorska DNA (ctDNA). cffDNA se primjenjuje u neinvazivnoj prenatalnoj dijagnostici trisomije 21, a njezine povišene koncentracije uočene su u komplikacijama trudnoće poput preeklampsije (PE), intrauterinog zastoja u rastu (IUGR) i prijevremenog porođaja. ctDNA se analizira tekućom biopsijom iz uzorka krvi, koja je u odnosu na klasičnu biopsiju brža, efikasnija i minimalno invazivna metoda. ctDNA posjeduje mutacije identične onima u tumorskim stanicama i ima kratko poluvrijeme života, zbog čega može pružiti informacije o trenutačnom stanju tumora u organizmu. Cilj ovog preglednog rada je sustavno analizirati i predstaviti dosadašnje spoznaje o cfDNA, cffDNA i ctDNA, budući da njihova primjena može rezultirati boljim dijagnostičkim i terapijskim ishodima.
Abstract (english)
The term cell-free DNA (cfDNA) refers to the circulating DNA fragments present in the blood of healthy and diseased individuals. Trophoblast and malignant tumors share certain characteristics, such as invasiveness, metastasis and angiogenesis, which is why the trophoblast tissue is also called the pseudomalignant tissue. Trophoblast and malignant tumor cells release specific DNA fragments into the blood named the cell-free fetal DNA (cffDNA) and circulating tumor DNA (ctDNA). cffDNA is used in non-invasive prenatal diagnosis for trisomy 21, and its elevated concentrations were observed in pregnancy complications such as preeclampsia (PE), intrauterine growth restriction (IUGR) and premature delivery. ctDNA is analyzed by liquid biopsy from a blood sample, which is faster, more efficient and minimally invasive method, compared to the tissue biopsy. ctDNA displays mutations identical to those in tumor cells and has a short half-life, making it able to provide information about the current state of tumor in the body. The aim of this review is to systematically analyze and present the current cfDNA, cffDNA and ctDNA findings, since their application can result in better diagnostic and therapeutic outcomes.
