Chronic hepatitis B infection caused by Hepatitis B virus (HBV), influences over two billion people worldwide despite having an effective vaccine. With a total prevalence of 4.57%, there are 3.3 million estimated HBV carriers in Türkiye. Methylene-tetrahydrofolate reductase (MTHFR) arrange folate metabolism through nucleic acid synthesis and DNA methylation. C677T (rs1801133, p.Ala222Val) and A1298C (rs1801131, p.Glu429Ala) polymorphisms of MTHFR gene have effect of reducing the activity of enzyme.

Identification of a new G-quadruplex ligand having anti-telomerase activity would be a promising strategy for cancer therapy. The screened compound from ZINC database using docking studies was experimentally verified for its binding with three different telomeric G-quadruplex DNA sequences and anti-telomerase activity in A549 cells. Identified compound is an intrinsic fluorescent molecule, permeable to live cells and has a higher affinity to 22AG out of three different telomeric G-quadruplex DNA. It showed cytotoxicity and a significant reduction of telomerase activity in human A549 cells at a very low dose...

BACKGROUND: Osteoporosis (OP) is a common systemic, metabolic bone disease that affects 40% of postmenopausal women. Oxidative stress (OS) ìs caused by reactive oxygen species (ROS), inhibits osteoblast differentiation and causes apoptosis in osteoblastic cells. Superoxide dismutase (SOD) reduces OS by playing a role in the reduction and defense of intracellular ROS. Therefore, the purpose of this study was to investigate the relationship between osteopenia/OP and the SOD1 50-bp insertion/deletion (I/D) variant in Turkish postmenopausal women...

A critical strategy to improve the properties of oligonucleotide therapeutics is using cationic molecules as carriers. We developed artificial cationic molecules that bind to A-type oligonucleotide duplexes, such as siRNAs, in a stoichiometric ratio. In this study, we investigated the properties of oligo 2,6-diamino-D-galactoses (ODAGals) and L-2,4-diaminobutanoic acid oligomers (Dabs) and revealed their thermal and biological stabilization effects on A-type duplexes and their chemical stability. As a result, ODAGal and Dab with the same number of amino groups had the commensurate ability for the biological stabilization effect, whereas Dab enhanced the thermal stability of A-type duplexes more effectively than ODAGal...

Genetic variations in the AGT gene play a significant role in controlling the plasma concentration of angiotensinogen (precursor protein of bioactive octapeptide angiotensin II) and the efficacy of antihypertensive drugs. In the current study, Tetra-Amplification Refractory Mutation System-Polymerase Chain Reaction (T-ARMS-PCR) was developed for genotyping of AGT rs699 T/C polymorphism and validated through Sanger DNA sequencing. Its efficiency was also tested using 474 human DNA samples [control, n = 181; cardiovascular disease (CVD) patients, n = 293]...

Toll-like receptors (TLRs) recognize infectious agents and play an important role in the innate immune system. Studies have suggested that TLR single nucleotide polymorphisms (SNPs) are associated with poor antiviral responses against SARS-CoV-2. Therefore, we aimed to investigate the relationship of TLR7 and TLR8 (SNPs) with COVID-19 disease prognosis. A total of 120 COVID-19 patients, 40 outpatients, 40 clinical ward patients and 40 intensive care unit (ICU) patients were included in the study. TLR7 (rs179009), TLR8-129 C/G (rs3764879) and TLR8 Met1Val (rs3764880) SNPs were genotyped using the PCR-RFLP method...

Oxidative stress (OS), which leads to DNA damage, plays a role in the pathogenesis of Coronavirus disease 2019 (COVID-19). We aimed to evaluate the role of DNA repair gene variants [X-ray repair cross complementing 4 ( XRCC4 ) rs28360071, rs6869366, and X-ray cross-complementary gene 1 ( XRCC1) rs25487] in susceptibility to COVID-19 in a Turkish population. We also evaluated its effect on the clinical course of the disease. A total of 300 subjects, including 200 COVID-19 patients and 100 healthy controls, were included in this study...

CDKN1A gene is implicated in cell differentiation, development process, repair, apoptosis, senescence, migration, and tumorigenesis. Somatic alterations and polymorphisms may interfere in the function of CDKN1A, and this could affect the individual susceptibility to colorectal cancer (CRC). Here in, we evaluated the importance of single nucleotide polymorphic variants in codon 31 of CDKN1A (rs1801270: C > A) for the development of colorectal cancer in an Iranian population. A total of 150 CRC patients and 150 healthy controls were enrolled in this study...

We describe a new demethylation method for dimethyl phosphonate esters using sodium ethanethiolate. The new procedure allows demethylation of nucleoside dimethyl phosphonate esters without 1'-α-anomerization, providing an improved synthesis of 5'-methylene substituted 2',5'-deoxynucleotides.

Bipolar disorder (BD) is a severe condition characterized by periods of mania and depression. Despite advances in the neurobiology of bipolar disorder, the exact etiology of the disease remains unclear. There is evidence that Inflammation is associated with bipolar disorder. COX-2 and NF-κB are two critical mediators in the inflammatory pathways. Long non-coding RNAs (lncRNAs) are a new class of non-coding RNAs that play a wide range of roles, especially in developing and maintaining normal brain functions...

The most common viral hemorrhagic fever is Crimean-Congo hemorrhagic fever (CCHF). Endothelial nitric oxide synthase (eNOS) gene polymorphisms have been linked to both hemorrhagic fevers and viral diseases. The study's goal is to evaluate if the eNOS gene 4a/4b and T786C polymorphisms are related to CCHF. The study included 54 CCHF RNA-positive patients and 60 control subjects. The Bosphore CCHF virus Quantification Kit v1 was used to obtain CCHF RNA, and the Magnesia 16 isolation device was used to isolate DNA (Anatolia Gene works, Turkey)...

lncRNAs play a crucial role in the carcinogenesis process. Thus, they have been recognized as the potential therapeutic and diagnostic biomarkers of cancers. This study assessed the alteration in the expression of APOC1P1-3 lncRNA in cancerous tissues compared to their adjacent non-tumorous tissues sampled from cervical cancer patients. one hundred fifteen pairs of cancerous and adjacent non-cancerous biopsy of cervical cancer specimens were collected. RNA isolation and cDNA synthesis were carried out. The qRT-PCR was used to assess the changes in the expression of APOC1P1-3 lncRNA...
