Article Citation - WoS: 4Citation - Scopus: 7The Importance of Protein Profiling in the Diagnosis and Treatment of Hematologic Malignancies(Galenos Yayıncılık, 2011) Şanlı Mohamed, Gülşah; Turan, Taylan; Ekiz, Hüseyin Atakan; Baran, YusufProteins are important targets in cancer research because malignancy is associated with defects in cell protein machinery. Protein profiling is an emerging independent subspecialty of proteomics that is rapidly expanding and providing unprecedented insight into biological events. Quantitative assessment of protein levels in hematologic malignancies seeks a comprehensive understanding of leukemiaassociated protein patterns for use in aiding diagnosis, follow-up treatment, and the prediction of clinical outcomes. Many recently developed high-throughput proteomic methods can be applied to protein profiling. Herein the importance of protein profiling, its exploitation in leukemia research, and its clinical usefulness in the treatment and diagnosis of various cancer types, and techniques for determining changes in protein profiling are reviewed.Article Citation - WoS: 31Citation - Scopus: 36Quercetin-Induced Apoptosis Involves Increased Htert Enzyme Activity of Leukemic Cells(Taylor and Francis Ltd., 2011) Avcı, Çığır Biray; Yılmaz, Sunde; Doğan, Zeynep Özlem; Saydam, Güray; Dodurga, Yavuz; Ekiz, Hüseyin Atakan; Kartal, Melis; Şahin, Fahri; Baran, Yusuf; Gündüz, CumhurWe aimed to examine the growth suppressive effects of quercetin on acute promyelocytic and lymphoblastic leukemia and chronic myeloid leukemia, and to find out whether the growth suppression is related to the blocking of telomerase enzyme activity. Cytotoxic effects of quercetin were shown by trypan blue analyses. Apoptotic effects of quercetin were examined by acridine orange and ethidium bromide staining by fluorescence microscopy. The effects of quercetin on telomerase enzyme activity were shown by hTERT Quantification Kit. Our results demonstrated that quercetin has antiproliferative and apoptotic effects on T-cell acute lymphoblastic leukemia (ALL), acute promyelocytic leukemia, and chronic myeloid leukemia (CML) cells. We also showed for the first time by this study that quercetin suppresses the activity of telomerase in ALL and CML cells. The results of this study show the importance of quercetin for its therapeutic potential in treatment of leukemias.
