Article Citation - WoS: 9Citation - Scopus: 11Pcr-Free Methodology for Detection of Single-Nucleotide Polymorphism With a Cationic Polythiophene Reporter(American Chemical Society, 2021) Yücel, Müge; Koç, Altuğ; UÜgenalp, Ayfer; Akkoç, Gün Deniz; Ceyhan, Metin; Yıldız, Ümit HakanThis study presents a nonamplification-based nucleic acid assay for the detection of single-nucleotide polymorphism (SNP) associated with familial Mediterranean fever (FMF) besides polymerase chain reaction (PCR)-based methodologies. The major objective is to show the potential of the proposed assay for rapid screening of FMF in a Mediterranean region of 400 million population. The assay relies on binding difference of specially designed wild and mutant primers to the target genomic DNA, followed by determination of unbound primers by quick titration of a cationic polythiophene reporter. The fluorescent reporter exhibits signal transition from 525 to 580 nm in the presence of unbound primers, and it correlates the binding affinity of label-free primers to the homozygous wild and mutant genomes. As a proof of concept, 26 real samples are studied relying on the ON and OFF fluorescence signals of the cationic polythiophene reporter. The results are analyzed by principal component analysis (PCA), which provides clear separation of healthy and patient individuals. The further analysis by support vector machine (SVM) classification has revealed that our assay converges to 96% overall accuracy. These results support that the PCR-free nucleic acid assay has a significant potential for rapid and cost-effective screening of familial Mediterranean fever.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 miRNA
