Abstract
Signalni put Notch u krvotvornim matičnim stanicama (KMS) koštane srži (KS) multiplog mijeloma (MM) analiziran je kroz ekspresiju proteina NOTCH1, JAGGED1, DLL1 u KMS imunofenotipizacijom, u tumorskim plazma stanicama (TPS) imunohistokemijskim bojenjem, uz analizu citogenetičkih promjena visokog rizika (CGVR) u TPS metodom FISH te analizu histoloških promjena u koštanoj srži MM. Ekspresija JAGGED1 i DLL1 u KMS značajno je niža u MM nego u zdravih darivatelja. Prisutna je negativna korelacija između ekspresije NOTCH1 i JAGGED1 u KMS MM, a pozitivna korelacija između ekspresije NOTCH1 i liganada JAGGED1 i DLL1 u TPS. U TPS s prisutnom barem jednom CGVR i difuznim infiltratom KS značajno je veća razina ekspresije NOTCH1 i JAGGED1 i intenziteta ekspresije NOTCH1. Potvrđena je hipoteza da postoji razlika u ekspresiji JAGGED1 i DLL1 u KMS u MM i zdravoj KS, no nije dokazana povezanost ekspresije NOTCH1, JAGGED1, DLL1 u KMS i TPS u MM. Povezanost ekspresije NOTCH1, JAGGED1 i DLL1 u istoj vrsti stanica ukazuje na razliku u homotipnoj i heterotipnoj staničnoj signalizaciji puta Notch u MM.
Abstract (english)
The Notch signaling pathway in hematopoietic stem cells (HSC) in the multiple myeloma (MM) bone marrow (BM) was analyzed with the NOTCH1, JAGGED1, DLL1 expression in HSC by immunophenotyping and in tumor plasma cells (TPC) by immunohistochemical staining. High risk cytogenetic changes (CGHR) using the FISH method and histological analysis of TPC in the BM MM was performed. JAGGED1 and DLL1 expression in HSC were significantly lower in MM than in healthy donors. There was a negative correlation between NOTCH1 and JAGGED1 expression in HSC MM, and a positive correlation between NOTCH1 and JAGGED1 and DLL1 in TPC, respectively. In TPC with at least one CGHR present and a BM diffuse infiltrate, the NOTCH1 and JAGGED1 expression and the intensity of NOTCH1 expression were significantly higher. The hypothesis that there is a difference in the expression of JAGGED1 and DLL1 in HSC between MM and healthy BM was confirmed, but the correlation of the NOTCH1, JAGGED1, DLL1 expression in HSC and TPC in MM was not proven. The association of NOTCH1, JAGGED1 and DLL1 expression in the same cell type indicates a difference in homotypic and heterotypic cellular signaling of the Notch pathway in MM.
