Funkcija

Ovaj gen kodira komponentu (NER) puta popravka nukleotidne ekscizijske. Postoji više komponenti uključenih u NER put, uključujući Xeroderma pigmentosum (XP) A-G i V, Cockayneov sindrom (CS) A i B, i trihotiodistrofijsku (TTD) grupu A, itd. Ova komponenta, XPC, ima važnu ulogu u ranim koracima globalnog genoma NER, posebno u prepoznavanju oštećenja, formiranju otvorenog kompleksa i popravljanju formiranja kompleksa proteina.^[4]

Kompleks XPC-RAD23B je početni faktor prepoznavanja oštećenja u globalnoj popravci ekscizijom genomskih nukleotida (GG-NER)).^[6] XPC-RAD23B prepoznaje širok spektar lezija koje termodinamički destabiliziraju DNK duplekse, uključujući UV-inducirane fotoproizvode (ciklopirimidinski dimeri i 6-4 fotoproizvodi), adukte formirane mutagenima iz okoliša kao što su benzo[a]piren ili različiti aromatski amini, određene oksidativne endogene lezije kao što su ciklopurini i adukti formirani hemoterapijskim lijekovima protiv raka kao što je cisplatin. Prisustvo XPC-RAD23B je potrebno za sklapanje drugih jedarnih faktora NER i progresiju kroz NER put i in vitro i in vivo.^[7] Iako je većina studija sprovedena sa XPC-RAD23B, on je dio trimernog kompleksa sa centrinom-2, proteinom koji vezuje kalcij iz porodice kalmodulina.^[7]

Klinički značaj

Mutacije ovog gena ili nekih drugih komponenti NER-a rezultiraju bolešću Xeroderma pigmentosum, rijetkim autosomno recesivnim poremećajem koji karakterizira povećana osjetljivost na sunčevu svjetlost s razvojem karcinoma u ranoj dobi.^[4]

Rak

Čini se da je oštećenje DNK primarni uzrok kancera,^[8] a nedostaci gena za popravak DNK vjerovatno su u osnovi mnogih oblika raka.^[9]^[10] Ako je popravak DNK nedovoljan, oštećenje DNK ima tendenciju da se akumulira. Takvo prekomjerno oštećenje DNK može povećati mutacije zbog sklonosti greškama translezijskim sintezama. Prekomjerno oštećenje DNK također može povećati epigenetičke promjene zbog grešaka tokom popravka DNK.^[11]^[12] Takve mutacije i epigenetičke promjene mogu dovesti do raka.

Smanjenje ekspresije gena za popravak DNK (obično uzrokovano epigenetičkim promjenama kao što je hipermetilacija promotora) vrlo je česta pojava kod karcinoma i obično je mnogo češća od mutacijskih defekata u genima za popravak DNK kod karcinoma. Tabela ispod pokazuje da je ekspresija XPC često epigenetički smanjena kod raka mokraćne bešike, kao i kod raka pluća nemalih ćelija, a također pokazuje da je XPC češće smanjen u naprednijim fazama ovih bolesti.

Učestalost smanjene ekspresije XPC kod karcinoma, sa stadijima koji su posebno naznačeni
Kancer	Učestalost	Referenca
Rak mokraćne bešike	50%	^[13]
Papilarna urotelna neoplazma niskog malignog potencijala	35%	^[13]
Papilarni karcinom mokraćne bešike niskog stepena	42%	^[13]
Papilarni rak mokraćne bešike visokog stepena	65%	^[13]
Nemaloćelijski rak pluća (NSCLC)	70%	^[14]
Stadij NSCLC	62%	^[14]
Stadij NSCLCII-III	77%	^[14]

Dok se pokazalo da je epigenetička hipermetilacija promotorskog regiona "XPC" gena povezana sa niskom ekspresijom XPC,^[13] drugi način epigenetičke represije "XPC" također se može pojaviti prekomjernom ekspresijom mikroRNK miR-890.^[15]

Interakcije

Pokazano je da XPC (gen) reaguje sa ABCA1,^[16] CETN2^[17] i XPB.^[18]
