Article Citation - WoS: 10Citation - Scopus: 14Enalapril-Induced Apoptosis of Acute Promyelocytic Leukaemia Cells Involves Stat5a(International Institute of Anticancer Research, 2012) Purçlutepe, Özlem; İskender, Güniz; Kiper, Hatice Demet; Tezcanlı, Burçin; Selvi, Nur; Biray Avcı, Çığır; Kosova, Buket; Adan Gökbulut, Aysun; Şahin, Fahri; Baran, Yusuf; Saydam, GürayBackground: In this study, we aimed at evaluating the cytotoxic and apoptotic effects of enalapril on human HL60 acute promyelocytic leukaemia cells and at clarifying the roles of signal transducers and activator of transcription proteins (STATs) on enalapril-induced cell death. Materials and Methods: Cell viability and cytotoxicity tests were conducted by Trypan blue dye exclusion and 2,3-Bis[2-methoxy-4-nitro-5-sulphophenyl]-2H-tetrazolium-5- carboxanilide inner salt (XTT) assays, respectively. Apoptotic analyses were performed by the AnnexinV-enhanced green fluorescent protein (EGFP) staining method and by fluorescence microscopy. Expression levels of STAT3, -5A and -5B genes were analysed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Results: The results showed that enalapril reduced viability and proliferation, and induced apoptosis in HL60 cells in a dose-and time-dependent manner as compared to untreated controls. The expression levels of STAT5A gene were significantly reduced in enalapril-treated HL60 cells as compared to untreated controls. Conclusion: Taken together, all data showed for the first time that enalapril has significant anticancer potential for the treatment of acute premyelocytic leukaemia.Article Citation - WoS: 28Citation - Scopus: 29Revealing Genome-Wide Mrna and Microrna Expression Patterns in Leukemic Cells Highlighted “hsa-Mir as a Tumor Suppressor for Regain of Chemotherapeutic Imatinib Response Due To Targeting Stat5a(SAGE Publications Inc., 2015) Tezcanlı Kaymaz, Burçin; Selvi Günel, Nur; Ceyhan, Metin; Bozok Çetintaş, Vildan; Özel, Buket; Kartal Yandım, Melis; Kıpçak, Sezgi; Aktan, Çağdaş; Adan Gökbulut, Aysun; Baran, Yusuf; Kosova Can, BuketBCR-ABL oncoprotein stimulates cell proliferation and inhibits apoptosis in chronic myeloid leukemia (CML). For cure, imatinib is a widely used tyrosine kinase inhibitor, but developing chemotherapeutic resistance has to be overcome. In this study, we aimed to determine differing genome-wide microRNA (miRNA) and messenger RNA (mRNA) expression profiles in imatinib resistant (K562/IMA-3 μM) and parental cells by targeting STAT5A via small interfering RNA (siRNA) applications. After determining possible therapeutic miRNAs, we aimed to check their effects upon cell viability and proliferation, apoptosis, and find a possible miRNAConference Object A Genome-Wide Analyses of Differentially Expressed Genes and Related Networks Affected by Fisetin and Hesperetin in Chronic Myeloid Leukemia Cells(Ferrata Storti Foundation, 2015) Adan Gökbulut, Aysun; Baran, Yusuf[No abstract available]Article Citation - WoS: 18Citation - Scopus: 21Intraperitoneal Mesenchymal Stem Cell Administration Ameliorates Allergic Rhinitis in the Murine Model(Springer Verlag, 2017) Işık, Sakine; Karaman, Meral; Adan, Aysun; Kıray, Müge; Bağrıyanık, Hüsnü Alper; Çağlayan Sözmen, Şule; Kozanoğlu, İlknur; Karaman, Özkan; Baran, Yusuf; Uzuner, NevinPrevious studies showed that bone marrow-derived mesenchymal stem cells (BMSCs) could ameliorate a variety of immune-mediated and inflammatory diseases due to their immunomodulatory and anti-inflammatory effects. In this study, we developed a mouse model of ovalbumin (OVA) induced allergic inflammation in the upper airways and evaluated the effects of the intraperitoneal administration of BMSCs on allergic inflammation. Twenty-five BALB/c mice were divided into five groups; group I (control group), group II (sensitized and challenged with OVA and treated with saline-placebo group), group III (sensitized and challenged with OVA and treated with 1 × 106 BMSCs), group IV (sensitized and challenged with OVA and treated with 2 × 106 BMSCs), and group V (sensitized and challenged with phosphate buffered saline (PBS) and treated with 1 × 106 BMSCs). Histopathological features (number of goblet cells, eosinophils and mast cells, basement membrane, epithelium thickness, and subepithelial smooth muscle thickness) of the upper and lower airways and BMSCs migration to nasal and lung tissue were evaluated using light and confocal microscopes. Levels of cytokines in the nasal lavage fluid and lung tissue supernatants were measured using enzyme-linked immunosorbent assay (ELISA). Confocal microscopic analysis showed that there was no significant amount of BMSCs in the nasal and lung tissues of group V. However, significant amount of BMSCs were observed in group III and IV. In OVA-induced AR groups (group II, III, and IV), histopathological findings of chronic asthma, such as elevated subepithelial smooth muscle thickness, epithelium thickness, and number of goblet and mast cells, were determined. Furthermore, the number of nasal goblet and eosinophil cells, histopathological findings of chronic asthma, and IL-4, IL-5, IL-13, and NO levels was significantly lower in both BMSCs-treated groups compared to the placebo group. Our findings indicated that histopathological findings of chronic asthma were also observed in mice upon AR induction. BMSCs migrated to the nasal and lung tissues following intraperitoneal delivery and ameliorated to the airway remodeling and airway inflammation both in the upper and lower airways via the inhibition of T helper (Th) 2 immune response in the murine model of AR.Conference Object Therapeutic Potential of Fisetin and Identification of Its Mechanisms in Action in Chronic Myeloid Leukemia and Acute Promyelocytic Leukemia Cells(John Wiley and Sons Inc., 2015) Adan Gökbulut, Aysun; Baran, Yusuf[No abstract available]Article Citation - WoS: 27Citation - Scopus: 36Purification and Biochemical Characterization of an Extracellular Lipase From Psychrotolerant Pseudomonas Fluorescens Ke38(TUBITAK, 2013) Adan Gökbulut, Aysun; Arslanoğlu, AlperAn extracellular lipase producing bacterium was isolated from a soil sample, and identified as a strain of Pseudomonas fluorescens by 16S rRNA gene sequencing. It was named Pseudomonas fluorescens KE38. KE38 showed psychrotolerant properties with an optimum growth temperature of 25 °C. The lipase enzyme secreted by KE38 was purified 41.13-fold with an overall yield of 54.99%, and a specific activity of 337.3 U/mg. The molecular mass of purified lipase was estimated to be approximately 43 kDa by SDS-PAGE. Although the lipase was active at a temperature range of 15-65 °C, it exhibited maximum activity at 45 °C, at pH 8.0. The enzyme exhibited high stability retaining 100% and 70% of its activity after an incubation period of 45 and 100 min at 45 °C and pH 8.0 respectively. It also showed a broad substrate specificity acting on p-nitrophenyl esters with C8-C18 acyl groups as substrates and was activated by Ca2+ and Ni2+ at 1 mM. While the enzyme retained its activity levels in the presence of a variety of organic solvents, DMSO and dimethylformamide enhanced this. High stability, broad substrate specificity and activity at cold temperatures in the presence of organic solvents, and metal ions make the extracellular lipase of KE38 a candidate for industrial applications.Conference Object Changes in Gene Expression Profiles in Response To Apigenin in Imatinib Sensitive and Resistant Chronic Myeloid Leukemia Cells(FERRATA STORTI FOUNDATION, 2013) Baran, Yusuf; Gökbulut, Aysun; Cincin, Zeynep; Çakmakoğlu, Bedia; Kozanoğlu, İlknur[No abstract available]Conference Object The Microarray Gene Profiling Analysis of Acute Promyelocytic Leukemia Cells in Response To Fisetin and Hesperetin(Ferrata Storti Foundation, 2015) Adan Gökbulut, Aysun; Baran, Yusuf[No abstract available]Article Citation - WoS: 42Citation - Scopus: 46Novel Agents Targeting Bioactive Sphingolipids for the Treatment of Cancer(Bentham Science Publishers, 2013) Adan Gökbulut, Aysun; Kartal Yandım, Melis; İskender, Güniz; Baran, YusufSphingolipids are a class of lipids that have important functions in a variety of cellular processes such as, differentiation, proliferation, senescence, apoptosis and chemotherapeutic resistance. The most widely studied bioactive shingolipids include ceramides, dihydroceramide (dhCer), ceramide-1-phosphate (C1P), glucosyl-ceramide (GluCer), sphingosine and sphingosine-1-phosphate (S1P). Although the length of fatty acid chain affects the physiological role, ceramides and sphingosine are known to induce apoptosis whereas C1P, S1P and GluCer induce proliferation of cells, which causes the development of chemoresistance. Previous studies have implicated the significance of bioactive shingolipids in oncogenesis, cancer progression and drug- and radiation-resistance. Therefore, targeting the elements of sphingolipid metabolism appears important for the development of novel therapeutics or to increase the effectiveness of the current treatment strategies. Some approaches involve the development of synthetic ceramide analogs, small molecule inhibitors of enzymes such as sphingosine kinase, acid ceramidase or ceramide synthase that catalyze ceramide catabolism or its conversion to various molecular species and S1P receptor antagonists. These approaches mainly aim to up-regulate the levels of apoptotic shingolipids while the proliferative ones are down-regulated, or to directly deliver cytotoxic sphingolipids like short-chain ceramide analogs to tumor cells. It is suggested that a combination therapy with conventional cytotoxic approaches while preventing the conversion of ceramide to S1P and consequently increasing the ceramide levels would be more beneficial. This review compiles the current knowledge about sphingolipids, and mainly focuses on novel agents modulating sphingolipid pathways that represent recent therapeutic strategies for the treatment of cancer. © 2013 Bentham Science Publishers.Conference Object Investigation of Effects of Fisetin, Vitexin and Hesperetin on Chronic Myeloid Leukemia Cells(Ferrata Storti Foundation, 2014) Adan Gökbulut, Aysun; Baran, Yusuf[No abstract available]
