Waxaan hore ula kulannay habab nidaamsan oo dihydrotestosterone (DHT) ay ku samaysay saameynteeda xakamaynta borotiinka hormoonka hormoonka parathyroid (PTHrP) cadaadiska hidda-wadaha iyada oo loo marayo soo-dhoweynta estrogen (ER) α, laakiin ma aha soo-dhoweynta androgen (AR), kansarka naasaha ee MCF-7 unugyada .Halkan, waxaan ku baarnay in isdhexgalka ligand-nuclear receptor (NR) uu ku jiro unugyada kansarka qanjirka 'prostate' ee unugyada LNCaP.Marka hore, waxaan xaqiijinay in unugyada LNCaP ay muujiyeen xaddi badan oo AR ah oo ku jira heerar la dayacay oo ah ERα/β ama progesterone receptor.Xakamaynta PTHrP iyo kicinta hiddo-wadaha antigen-ka qanjirka 'prostate-gaar ah ayaa la arkay ka dib markii la maamulay madax-bannaanida 17β-estradiol (E2), DHT, ama R5020.Iyada oo la raacayo fikradda ah in LNCaP AR ay lumisay gaarnimadiisa ligand sababtoo ah isbeddelka (Thr-Ala877), tijaabooyinka siRNA ee lagu beegsanayo NR-da ayaa shaaca ka qaaday in AR ay keligeed keligeed isku koobtay doorka dhexdhexaadiyaha ee nidaamka hormoonka-ku-tiirsanaanta la wadaago, kaas oo si aan kala go 'lahayn ula xiriirin. oo leh beddelka nukliyeerka n ee mutant AR.Falanqaynta Microarray ee habaynta hidda-sidaha DHT, E2, ama R5020 ayaa shaaca ka qaaday in in ka badan kala badh hiddo-wadaha hoose ee AR (Thr-Ala877) ay ku dul-kordhmeen unugyada LNCaP.Xiiso gaar ah, waxaan ogaanay in AR (nooca duurjoogta ah [wt]) iyo AR (Thr-Ala877) ay si siman mas'uul uga yihiin isdhexgalka E2-AR.Tijaabooyinka microscopy fluorescence waxay muujiyeen in EGFP-AR (wt) iyo EGFP-AR (Thr-Ala877) labaduba ay si gaar ah u degaan gudaha xudunta ka dib daaweynta E2 ama DHT.Intaa waxaa dheer, qiimeynta weriyeyaasha ayaa shaaca ka qaaday in qaar ka mid ah unugyada kale ee kansarka ay muujiyeen aberrant E2-AR (wt) oo calaamad u ah kuwa ku jira unugyada LNCaP.Waxaan halkaan ku soo gudbineynaa joogitaanka isdhexgalka isku xiran ee u dhexeeya wt AR iyo E2 ee unugyada kansarka xasaasiga ah ee hormoonka qaarkood.
