Conference Object Suppression of STAT5A Increases Chemotherapeutic Sensitivity in Imatinib-Resistant and Imatinib-Sensitive K562 Cells(Ferrata Storti Foundation, 2010) Baran, Y.; Baran, Yusuf; Kosova, B.; Ekiz, Hüseyin Atakan; Tezcanli, B.; Ekiz, H.; Cakir, Z.; Selvi, S.Review Citation - WoS: 9Citation - Scopus: 7Micrornas and Long Non-Coding Rnas as Novel Targets in Anti-Cancer Drug Development(Bentham Science Publishers, 2023) Çetinkaya, Melisa; Baran, YusufNon-coding RNAs comprise the majority of RNAs that have been transcribed from the human genome, and these non-coding RNAs have essential regulatory roles in the cellular processes. They have been discovered to influence the expression of the genes, including tumor-suppressive and oncogenes, that establish the non-coding RNAs as novel targets for anti-cancer drug development. Among non-coding RNAs, microRNAs have been extensively studied in terms of cancer biology, and some microRNA-based therapeutics have been reached in clinical studies. Even though most of the research regarding targeting non-coding RNAs for anti-cancer drug development focused on microRNAs, long non-coding RNAs have also started to gain importance as potential therapeutic targets for cancer therapy. In this chapter, the strategies and importance of targeting microRNAs and long non-coding RNAs will be described, along with the clinical studies that involve microRNA-based cancer therapeutics and preclinical studies that involve long non-coding RNA-based therapeutics. Finally, the delivery strategies that have great importance in the effective delivery of the non-coding RNA-based cancer therapeutics, hence the therapy's effectiveness, will be described.Conference Object Determination of Therapeutic Effects of Multifunctional Micelle-Based Nanocarriers on Breast Cancer Cells(Elsevier, 2021) Ulu, Gizem Tuğçe; Bayram, Nazende Nur; Abdulhadi, N.; Gurdap, S.; Isoglu, A.; Isoglu, S. D.; Baran, YusufBackground: Breast cancer is the most common and frequent cause of death in women in all types of cancer. Current treatment protocols do not provide a complete cure and targeting therapy can provide an important avenue for successful treatment of breast cancer. In this study, we aim to determine the therapeutic effects of the drug-conjugated carrier system with the conjugation of peptide sequence and antibody on HER2-positive breast cancer cells.Article Citation - WoS: 37Mechanisms of Cellular Resistance To Imatinib in Human Chronic Myeloid Leukemia Cells(Taylor and Francis Ltd., 2007) Baran, Yusuf; Ural, Ali Uğur; Gündüz, UfukA major advancement in the treatment of chronic myeloid leukemia (CML) has been the development of imatinib, which has shown striking activity in the chronic phase and the accelerated phase, but less so in the blast phase of the disease. Despite high rates of hematologic and cytogenetic responses to therapy, the emergence of resistance to imatinib has been recognized as a major problem in the treatment of patients with CML. Various cellular mechanisms may be involved in the nature of cellular resistance. Increased amount of target, alteration in structure of target proteins, decreased drug uptake and increased detoxification are well-known mechanisms of resistance. On the other hand, in some cases, even if anticancer drugs reach their sites of action, bypassing drug efflux system of the cells, some cells still may survive via the dysregulation of apoptotic signalling. In this study, mechanisms of resistance to imatinib-induced apoptosis in human Meg-01 CML cells were examined. Continuous exposure of cells to step-wise increasing concentrations of imatinib resulted in the selection of 200- and 1000 nM imatinib-resistant sub-lines referred to as Meg-01/IMA-0,2 and Meg-01/1MA-1, respectively. MTT cell proliferation, cell cycle analyses and trypan blue dye exclusion analyses showed that Meg-0l/IMA-1 cells were resistant to imatinib-induced apoptosis as compared to parental sensitive cells. There was an increased expression of BCR/ABL, Bcl-2 and an increase in mitochondrial membrane potential (MMP) detected in resistant cells comparing to parental sensitive cells. There was no mutation detected in imatinib binding site of ABL kinase region. Various diverse mechanisms have been reported for their involvement in the multidrug resistance. In this study, it has been shown that the degree of BCR/ABL expression appears to be directly proportional to the levels of imatinib resistance. In addition, there have been BCR/ABL-independent mechanisms reported for deriving resistance against imatinib. Our results revealed that besides BCR/ABL overexpression, imatinib resistance also depends on the inhibition of apoptosis as a result of up-regulation of anti-apoptotic stimuli and down-regulation of pro-apoptotic stimuli through MMP but does not depend on any mutation on imatinib binding site of ABL kinase.Conference Object Cytotoxic Effects of Apigenin on Multiple Myeloma Cells(Ferrata Storti Foundation, 2013) Baran, Yusuf; Yılmaz, S.; Cincin, Zeynep; Kozanoğlu, İlknur; Çakmakoğlu, Bedia; Özdoğu, Hakan[No abstract available]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 Determination of Cytotoxic and Apoptotic Effects of Caffeic Acid Phenethyl Ester and Gossypol in Combination With Fludarabine at a Molecular Level in Acute Lymphoblastic Leukemia Cells(Ferrata Storti Foundation, 2013) Baran, Yusuf; İskender, G.; Pişkin, Özden; Özcan, Mehmet Ali[No abstract available]Conference Object Diagnostic and Therapeutic Potentials of Expression Levels of Bioactive Sphingolipid Genes in Newly Diagnosed and Drug-Resistant Chronic Myeloid Leukemia Patients(Ferrata Storti Foundation, 2013) Baran, Yusuf; Yandım, Melis; Kozanoğlu, İlknur; Özdoğu, Hakan; Pişkin, Özden; Özcan, Mehmet Ali[No abstract available]Conference Object Immunologically Detection of Bcr/Abl Fusion Protein With Flow Cytometry in K562 Chronic Myeloid Leukemia Cells and Comparison With Rt-Pcr Results(Ferrata Storti Foundation, 2013) Kozanoğlu, İlknur; Aygün, B.; Boğa, I.; Cansun, C.; Üstündağ, N.; Baran, Yusuf; Özdoğu, Hakan[No abstract available]Conference Object Comparison of Ishage-Based Cd34 (+) Cell Enumeration Protocols on Bd Facs Canto Iı and Attune Flow Cytometers(Nature Publishing Group, 2014) Kozanoğlu, İlknur; Ünver, Gülşah; Sarıtürk, Çağla; Baran, Yusuf; Yeral, Mahmut; Boğa, Can; Özdoğu, Hakan[No abstract available]
