SOX9
Transkripcijski faktor SOX-9 je protein koji kod ljudi kodiran genom SOX9.[5][6]
Funkcija
[uredi | uredi izvor]SOX-9 prepoznaje sekvencu CCTTGAG, zajedno sa ostalim članovima DNK-vezujućih proteina klase HMG-boksa. Ispoljava se proliferirajućim, ali ne hipertrofijskim hondrocitima, što je neophodno za diferencijaciju prekursorskih ćelija u hondrocite.[7] i, sa stereoidnim faktorom 1, regulira transkripciju gena antimelerovskog hormona antimüllerovakog hormona (AMH).[6]
SOX-9 također ima ključnu ulogu u spolnom razvoju muškaraca; radeći sa Sf1, SOX-9 može proizvesti AMH u Sertolijevim ćelijama da inhibira stvaranje ženskog reproduktivnog sistema.[8] Također komunicira s nekoliko drugih gena kako bi pospješio razvoj muških spolnih organa. Proces započinje kada faktor transkripcije testis-determinirajući faktor (kodiran iz regije za određivanje spola SRY Y hromosoma aktivira aktivnost SOX-9 vezivanjem za pojačivač uzvodne sekvence.[9] Nadalje, Sox9 aktivira FGF9 i formira povratne petlje sa FGF9[10] i PGD2.[9] Ove petlje su važne za proizvodnju SOX-9; bez njih, SOX-9-a bi ponestalo i gotovo sigurno bi uslijedio razvoj ženke. Aktivacija FGF9 puem SOX-9 pokreće vitalne procese u razvoju muškarca, poput stvaranja testisnih vrpci i umnožavanja Sertolijevih ćelija.[11] U razvoju mozga, njegov mišji ortolog Sox-9 inducira ekspresiju Wwp1, Wwp2 i miR-140 za regulaciju ulaska u korteksne ploče novorođenih nervnih ćelija i reguliranje grananja i stvaranje aksona u korteksnim neuronima.[12]
Klinički značaj
[uredi | uredi izvor]Mutacije dovode do sindroma koštane malformacije zvane kampomelna displazija, često sa autosomnom reverzijom spola [6] i rascijepljeno nepce.[13]
Kod ljudi, SOX9 nalazi se u „genskoj pustinji“, na poziciji 17q24. Delecije, prekidi pomoću translokacije prelomnih tačaka i jednotočkastim mutacijaama visoko konzerviranih nekodirajućih elemenata lociranih > 1 Mb iz jedinice transkripcije s obje strane SOX9, povezane su sa Pierre-Robinovom sekvencom, često sa rascjepom nepca.[13][14]
Protein Sox9 sudjelovao je u pokretanju i napredovanju više solidnih tumora. funkcije Sox9 u [15] Njegova uloga kao glavnog regulatora morfogeneze tokom razvoja čovjeka čini ga idealnim kandidatom za perturbaciju u malignim tkivima. Konkretno, čini se da Sox9 izaziva invazivnost i otpornost na terapiju kod rakova prostati[16] kolorektuma,[17]dojkama[18] i drugim kancerina, a ponekad promovira i letalne metastaze.[19] Izleda da mnogi od ovih onkogenih efekata Sox9 ovise od doze.[20]
Kokalizacija i dinamika SOX9-a
[uredi | uredi izvor]SOX9 je uglavnom lokaliziran u jedru i vrlo je mobilan. Studije na ćelijskoj liniji hondrocita otkrile su da je gotovo 50% SOX9-a vezano za DNK i izravno je reguliran vanjskim faktorima. Njegovo poluvrijeme boravka na DNK je ~ 14 sekundi.[21]
Uloga u reverziji spola
[uredi | uredi izvor]Mutacije u Sox9 ili bilo koji pridruženi geni mogu izazvatireverziju pola i hermafroditizam (ili intersekse kod ljudi). Ako Fgf9, koji aktivira Sox9, nije prisutan, fetus s X i Y hromosomom može razviti ženske spolne žlijezde; isto vrijedi i ako nije prisutan Dax1.[11] Srodni fenomeni hermafroditizma mogu biti uzrokovani neobičnom aktivnošću SRY, obično kada se translocira na X-hromosom i njegova aktivnost pokrene se samo u nekim ćelijama.[22]
Interakcije
[uredi | uredi izvor]Dokazano je da SOX9 ima interakcije sa steroidogenim faktorom 1,[8] MED12.[23] and MAF.[24]
