Funkcija

Ovaj gen kodira člana porodice interferonskih regulatornih transkripcijskih faktora (IRF). Članovi porodice dijele visoko konzerviran N-terminal helix-turn-helix DNK-vezujući domen i manje očuvan C-terminal domen za vezivanje proteina.^[7] Funkcija IRF6 povezana je s formiranjem veznog tkiva, na primjer onog nepca.^[8] Ovaj gen kodira člana porodice interferonskog regulatornog transkripcionog faktora (IRF). Osim toga, uočeno je da je gen IRF6 pod epigenetičkom regulacijom promotora metilacij DNK.^[9]

Patologija

Mutacija IRF6 gena može dovesti do autosomno dominantnog van der Woudeovog sindroma (VWS)^[10] ili srodnog sindroma poplitelnog pterigija (PPS).^[11] Van der Woudeov sindrom može uključivati rascjep usne i nepca, zajedno sa dentalnim anomalijama i fistulama usana. Osim toga, uobičajeni aleli u IRF6 su također povezani sa nesindromskim slučajevima rascjepa usne i/ili nepca prema studiji asocijacije na cijelom genomu i u mnogim studijama kandidata za gen.^[12] Ovi poremećaji uzrokovani su mutacijama u genu IRF6, a dio fenotipske heterogenosti uzrokovan je različitim tipovima mutacija IRF6-a.^[5] Jedno objašnjenje za ovu fenotipsku varijaciju između sindroma zasniva se na različitom uticaju na strukturu dimerizovanih mutantnih proteina. Čini se da VWS mutacije rezultiraju haploinsuficijencijom dok PPS mutacije mogu biti dominantno negativne prirode.^[13] Spektar mutacija u VWS i PPS nedavno je sumarizovan.^[14] Pokazalo se da IRF6 ima ključnu ulogu u razvoju keratinocita.^[15]^[16] Uloga IRF6 u uobičajenim oblicima je također demonstrirana je i u slučajevima rascjepa usne i nepca ^[17] i može objasniti samo ~20% slučajeva rascjepa usne.^[18] Varijante u IRF6 dale su dosljedne dokaze o povezanosti sa sindromskim rascjepom i/ili nepcem u više studija. Studija Birnbauma i kolega iz 2009. godine potvrdila je uticaj ovog gena na etiologiju rascjepa usne i/ili nepca, a studija GENEVA Cleft Consortium, koja je proučavala porodice iz više populacija, ponovo je potvrdila nalaze da su mutacije IRF6 snažno povezane s rascjepom usne i/ili nepca. Uloga IRF6 u izazivanju rascjepa usne i/ili nepca dalje je podržana analizom IRF6 mutantnih miševa koji pokazuju hiperproliferativnu epidermu koja ne prolazi kroz terminalnu diferencijaciju, što dovodi do višestrukih epitelnih adhezija koje mogu začepiti usnu šupljinu i rezultirati rascjepom nepca. Istraživanja na životinjskim modelima pokazuju da IRF6 određuje proliferaciju keratinocita i također ima ključnu ulogu u formiranju usnn periderme. Nedavno, korištenjem genetike miša, analiza ekspresije gena, studija imunoprecipitacije hromatina i testova reportera luciferaze, pokazalo se da je IRF6 direktna meta p63, koji je u osnovi nekoliko sindromskih malformacija, koje uključuju obilježja rascjepa, a p63 aktivira transkripciju IRF6 putem IRF6 pojačivačkog elementa. Varijacije u elementu pojačivača povećavaju podložnost samo rascjepu usne. I rascjep usne sa ili bez rascjepa nepca i samo rascjepom nepca uočene su u porodicama sa mutacijom IRF6-a. Osim toga, različiti tipovi rascjepa mogu se odvojiti unutar iste porodice.^[12]

Epigenetika

Uočeno je da je aberantni promotor IRF6 hipermetilacije DNK povezan sa pojavom/progresijom raka. Zaista, ovaj neprikladan epigenetički fenomen uočen je kod žena zahvaćenih kancerom vulvinih pločastih ćelija nastao je iz vulver lichen sclerosus.^[19] Metilacija promotora IRF6 može biti marker rizika od raka kod pacijenata oboljelih od ove bolesti.^[9]

Kancer

Uočeno je da je gen IRF6 progresivno smanjen u ljudski papiloma virus-pozitivnim neoplastični keratinociti izvedenim iz cerviksne preneoplazijske lezije na različitim nivoima malignosti.^[20] Iz tog razloga, ovaj gen je vjerovatno povezan s tumorigenezom i može biti potencijalni prognostički marker za progresiju preneoplazijske lezije grlića maternice.^[20] Slično tome, otkriveno je da je IRF6 genetički i epigenetički nereguliran u raku vulve.^[9]
