Tumorski protein p63, obično zvani p63, također poznat i kao protein vezan za transformaciju 63 jest protein koji je kod ljudi kodiran genom TP63 sa hromosoma 3.[5][6][7][8]

Gen TP63 je otkriven 20 godina nakon otkrića p53 tumor supresorskog gena i zajedno sa p73 čini porodicu gena p53, zasnovanu na na njihovoj strukturnoj sličnosti.[9] Iako je otkrivena znatno kasnije od p53, filogenetska analiza p53, p63 i p73 sugerira da je p63 bio originalni član porodice iz koje su evoluirali p53 i p73.[10]

Funkcija

[uredi | uredi izvor]

Tumorski protein p63 je član porodice transkripcijskih faktora p53. Miševi p63 –/– imaju nekoliko razvojnih defekata koji uključuju nedostatak udova i drugih tkiva, kao što su zubi i mliječne žlijezde, koji se razvijaju kao posljedica interakcije između mezenhim i epitel a. TP63 kodira dvije glavne izoforme pomoću alternativnih promotora (TAp63 i ΔNp63). ΔNp63 je uključen u višestruke funkcije tokom razvoja kože i u regulaciju matičnih/progenitornih ćelija odraslih.[12] Nasuprot tome, TAp63 je uglavnom bio ograničen na svoju apoptotsku funkciju, a u novije vrijeme i kao čuvar integriteta oocita.[13] Nedavno su TAp63 pripisane dvije nove funkcije u razvoju srca [14] i preranom starenju.[15]

Kod miševa, p63 je neophodan za normalan razvoj kože putem direktne transkripcije membranskog proteina PERP. TP63 također može regulirati ekspresiju PERP sa TP53 kod ljudskog kancera.[16]

Klinički značaj

[uredi | uredi izvor]

Mutacije TP63 su u osnovi nekoliko sindromskih malformacija koje uključuju rascjep usne i/ili nepca kao karakterističnu osobinu.[17] Mutacije u TP63 genu su povezane sa ektrodaktilno-ektodermnom displazijom sindroma rascjepa kod kojeg je rascjep usne po sredini uobičajena karakteristika,[17] uz sindrom rascjepa usne/nepca 3 (EEC3); ektodaktilija (takođe poznata kao malformacija podijeljene šake/stopala 4 (SHFM4)), ankiloblefaron-ektodermna displazija-rascjep usne/nepca (AEC) ili Hay-Wellsov sindrom kod kojih je rascjep usne po sredini također uobičajena oznaka,[17] Acro–dermato–ungual– suzno-zubni sindrom (odraslih); sindrom udova i dojke; Rap-Hodgkinov sindrom (RHS) i orofacijalni rascjep 8.

p63 bojenje na tkivu raka prostate korištenjem klonskojg antitijela IHC063

Uočeno je je da se i rascjep usne sa ili bez rascjepa nepca i samo rascjep nepca segregiraju unutar iste porodice s mutacijom TP63.[17] Nedavno su proizvedene inducirane pluripotentne matične ćelije pacijenata pogođenih EEC sindromima, reprogramiranjem ćelija. Defektna vezanost epitela može se djelimično spasiti malim terapeutskim spojem.[18]

Rak vulve

[uredi | uredi izvor]

Uočeno je da je TP63 prekomjerno eksprimiran u uzorcima karcinom vulvnih pločastih ćelija, u vezi sa inaktivacijom gena za supresor tumora, izazvanom hipermetilacijom IRF6.[19] Odista, nivoi iRNK TP63 testirani su u uzorcima raka vulve, u poređenju sa onima normalne kože i preneoplazijskih lezija vulve, čime se naglašava epigenetička unakrsna veza između gena IRF6 i onkogena TP63.[19]

Dijagnostičkinamjenskii program

[uredi | uredi izvor]

Imunobojenje p63 koristi se za karcinome skvamoznih ćelija glave i vrata, diferencirajući adenokarcinom (najčešći tip karcinoma prostate) i benigno tkivo prostate;[20] normalne žlijezde prostate obojene su p63 (jer imaju bazne ćelije), dok maligne žlijezde u adenokarcinomu prostate (kome nedostaju ove ćelije) nemaju.[21] P63 je također od pomoći u razlikovanju slabo diferenciranog karcinoma pločastih ćelija karcinoma malih ćelijkac ili adenokarcinoma. P63 treba biti jako obojen u slabo diferenciranim pločastim, ali negativan u malim ćelijama ili adenokarcinomu.[22]

Interakcije

[uredi | uredi izvor]

Pokazalo se da je TP63 u interakciji sa HNRPAB.[23] Također aktivira transkripciju IRF6 preko elementa pojačivača IRF6.[17]

Regulacija

[uredi | uredi izvor]

Postoje neki dokazi da ekspresiju p63 regulira mikroRNK miR-203[24][25] i USP28.
