BCL2L2
Bcl-2-liki protein 2 je 193-aminokiselinski protein koji je kod ljudi kodiran genom BCL2L2 sa hromosoma 14, sekvenca q11.2-q12.[5][6][7] Izvorno su ga otkrili Leonie Gibson, Suzanne Cory i kolege sa Walter i Eliza Hall Institute of Medical Research, koji su ga nazvali Bcl-w.[8]

Funkcija
[uredi | uredi izvor]Ovaj gen kodira člana za preživljavanje (antiapoptotoznog) iz porodice protrina bcl-2, a najsličniji je Bcl-xL.[7] Proteini ove porodice tvore hetero– ili homodimere i djeluju kao anti– i proapoptozni regulatori . Pokazalo se da ekspresija ovog gena u ćelijama doprinosi smanjenoj učestalosti apoptoza ćelija u uslovima citotoksičnosti. Studije srodnog gena na miševima ukazale su na ulogu u preživljavanju NGF i BDNF-zavisnih neurona. Studije mutacije i gena nokaut-miševa pokazale su ključnu ulogu u spermatogenezi kod odraslih.[6][7][10]
Klinički značaj
[uredi | uredi izvor]Visok nivo Bcl-w uočen je kod mnogih karcinoma, uključujući glioblastom, kolorektumski karcinom, karcinom pluća nemalih ćelija i rak dojke.[7] Pacijenti sa rakom dojke sa metastazama imaju veći Bcl-w od onih sa rakom dojke koji imaju samo primarni tumor.[7] Pokazano je da povišeni nivoi Bcl-w štite neurone od ćelijske smrti izazvane amieloidom-beta.[7] Pacijenti sa Parkinsonovim bolesti, sa mutiranim genom PARK2 imaju povišeni Bcl-w. Pokazano je da [7] Bcl-w doprinosi ćelijskom starenju.[7]
Pokazano je da kvercetin inhibira PI3K/AKT put, što dovodi do podregulacije Bcl-w.[7][11]
