Licensee MDPI, Basel, Switzerland.Epitranscriptomic modifications in RNA can dramatically alter the way our genetic code is deciphered. Cells utilize these modifications not only to maintain physiological processes, but also to respond to extracellular cues and various stressors. Most often, adenosine residues in RNA are targeted, and result in modifications including methylation and deamination. Such modified residues as N-6-methyl-adenosine (m6A) and inosine, respectively, have been associated with cardiovascular diseases, and contribute to disease pathologies. The Ischemic Heart Disease Epitranscriptomics and Biomarkers (IHD-EPITRAN) study aims to provide a more comprehensive understanding to their nature and role in cardiovascular pathology. The study hypothesis is that pathological features of IHD are mirrored in the blood epitranscriptome. The IHD-EPITRAN study focuses on m6A and A-to-I modifications of RNA. Patients are recruited from four cohorts: (I) patients with IHD and myocardial infarction undergoing urgent revascularization; (II) patients with stable IHD undergoing coronary artery bypass grafting; (III) controls without coronary obstructions undergoing valve replacement due to aortic stenosis and (IV) controls with healthy coronaries verified by computed tomography. The abundance and distribution of m6A and A-to-I modifications in blood RNA are charted by quantitative and qualitative methods. Selected other modified nucleosides as well as IHD candidate protein and metabolic biomarkers are measured for reference. The results of the IHD-EPITRAN study can be expected to enable identification of epitranscriptomic IHD biomarker candidates and potential drug targets.

Cloning and expression of the Clostridium thermocellum L-lactate dehydrogenase gene in Escherichia coli and enzyme characterization Ozkan, M; Yilmaz, EI; Lynd, LR; Özcengiz, Gülay (Canadian Science Publishing, 2004-10-01) The structural gene for L-lactate dehydrogenase (LDH) (EC.1.1.1.27) from Clostridium thermocellum 27405 was cloned in Escherichia coli by screening the Lambda Zap 11 phage library of C. thermocellum genomic DNA. In one positive clone, an open reading frame of 948 base pairs corresponded to C. thermocellum ldh gene encoding for the predicted 315-residue protein. The ldh gene was successfully expressed in E. coli FMJ39 (ldh mutant) under the lac promoter. The recombinant enzyme was partially purified from E. ...
Building Dicer1 regulation network of mouse liver hepatocytes Ünsal, Şeyma; Beyge, Mahmut; Aydın Son, Yeşim (2012-06-29) RNA induced gene silencing complex (RISC) has a role in many cellular processes which includes regulation of gene expression, immune response, cell differentiation and embryonic development. Dicer protein is a key regulator of these processes. Dicer1 specifically has central role in maturation of RISC substrate RNA and RISC assembly in mouse. Here the results of a microarray study that investigates the molecular level changes in dicer1 knockout mouse liver hepatocytes is re-analysed and the differentially r...
intI1 Type Mobile Genetic Elements Co-selected Antibiotic-Resistant Genes in Untreated Hospital Wastewaters Kayali, Osman; İçgen, Bülent (2021-01-01) Dissemination of antibiotic-resistant genes (ARGs) from hospital wastewaters (HWWs) is facilitated by the horizontal gene transfer (HGT) and involves association of ARGs with mobile genetic elements (MGEs). In our previous study, HWWs were found to have relatively high copy numbers of ARGs aadA, tetA, cmlA, sul1, and qnrS. In this study, therefore, the same HWWs were also monitored for 3 MGEs class 1 integron (intI1), insertion sequence common region 1 (ISCR1) and conjugative transposon Tn916/Tn1545 by usin...
APOBEC3B expression in drug resistant MCF-7 breast cancer cell lines Onguru, Onder; Yalcin, Serap; Rosemblit, Cinthia; Zhang, Paul J.; Kilic, Selim; Gündüz, Ufuk (2016-04-01) APOBEC3B belongs to a protein family of cytidine deaminases that can insert mutations in DNA and RNA as a result of their ability to deaminate cytidine to uridine. It has been shown that APOBEC3B-catalysed deamination provides a chronic source of DNA damage in breast cancers. We investigated APOBEC3B expression in four drug resistant breast cancer cell lines (Doxorubicin, Etoposide, Paclitaxel and Docetaxel resistant MCF-7 cell lines) using a novel RNA in situ hybridization technology (RNAscope) and compare...
Integrability of a generalized Ito system: The Painleve test Karasu-Kalkanli, A; Karasu, Atalay; Sakovich, SY (Physical Society of Japan, 2001-05-01) It is shown that a generalized Ito system of four coupled nonlinear evolution equations passes the Painleve test for integrability in five distinct cases, two of which were introduced recently by Tam et al. [H. W. Tam, X. B. Hu, D. L. Wang: J. Phys. Sec. Jpn. 68 (1999) 369]. A conjecture is formulated on integrability of a vector generalization of the Ito system.
