ARID3A and ARID3B exert direct regulatory control over the long non-coding RNAs (lncRNAs) MALAT1 and NORAD within the context of non-small cell lung cancer (NSCLC).

Lung cancer, known for its high mortality rates and poor prognosis, remains one of the most prevalent cancer types. Early detection and effective treatment methods are crucial for improving survival rates. Non-small cell lung cancer (NSCLC) accounts for approximately 85 % of all lung cancer cases.

Effects of antidiabetics and exercise therapy on suppressors of cytokine signaling-1, suppressors of cytokine signaling-3, and insulin receptor substrate-1 molecules in diabetes and obesity.

Objective: Pathological destruction of insulin signaling molecules such as insulin receptor substrate, especially due to the increase in suppressors of cytokine signaling molecules, has been demonstrated in experimental diabetes. The contribution of suppressors of cytokine signaling proteins to the development of insulin resistance and the effects of antidiabetic drugs and exercise on suppressors of cytokine signaling proteins are not clearly known.

Methods: A total of 48 Wistar albino adult male rats were divided into six groups: control group, obese group with diabetes, obese diabetic rats treated with metformin, obese diabetic rats treated with pioglitazone, obese diabetic rats treated with exenatide, and obese diabetic rats with applied exercise program.

The role of endothelial nitric oxide synthase gene polymorphisms in patients with lung cancer.

Objectives: Lung cancer is a disease characterized by uncontrolled cell growth in the lung tissues. The most common causes of lung cancer include smoking, exposure to radon gas, asbestos, environmental pollutants as well as genetic factors. Nitric oxide (NO) has potential mutagenic and carcinogenic activity and may play an important role in lung cancer.

Increased potassium excretion in children with monosymptomatic nocturnal enuresis: could it be related to Kir 4.1- KCNJ10 gene polymorphism?

Background And Objectives: There are controversial results in the literature regarding urinary electrolytes, especially potassium, in enuretic children. KCNJ10 channel protein, a member of the Kir 4.1 family is expressed in renal distal tubules and has an important function in renal ion transport.

Might there be a link between intron 3 VNTR polymorphism in the XRCC4 DNA repair gene and the etiopathogenesis of rheumatoid arthritis?

DNA repair genes are involved in several diseases such as cancers and autoimmune diseases. Previous studies indicated that a DNA repair system was involved in the development of rheumatoid arthritis (RA). In this study, we aimed to examine whether four polymorphisms in the DNA repair genes (xeroderma pigmentosum complementation group D [XPD], X-ray repair cross-complementing group 1 [XRCC1], and X-ray repair cross-complementing group 4 [XRCC4]) were associated with RA.

Association of an LMP2 polymorphism with acute myeloid leukemia and multiple myeloma.

Hematological malignancies (HM) are a group of neoplasms derived from the cells of the bone marrow and lymphatic system. Genetic factors leading to susceptibility to HM have been investigated for years but little is known yet. Low molecular weight polypeptide (LMP) 2 and LMP7 genes are important subunits of the immunoproteasome and play significant role in antigen presentation.

Association of TAP1 and TAP2 gene polymorphisms with hematological malignancies.

Transporter associated with antigen presenting (TAP) 1 and TAP2 genes are localized in the major histocompatability complex (MHC) class II region and form a heterodimer playing a key role in endogenous pathways for antigen presentation. Defects of these genes have been reported to be common in different types of cancer. Polymorphisms identified in these loci have also been investigated and reported to be associated with several autoimmune disorders, viral infections and neoplasms.

Mitochondrial uncoupling protein 2 (UCP2) gene polymorphisms are associated with childhood obesity and related metabolic disorders.

Objective: This study aimed to investigate the possible role of uncoupling protein 2 (UCP2) gene polymorphisms in childhood obesity and related metabolic disorders.

Methods: Obese patients (n=100) and healthy controls (n=100) were analyzed for -866G>A and insertion/deletion (I/D) polymorphisms of the UCP2 gene by polymerase chain raction and/or restriction fragment length polymorphism.

Results: UCP2 I/D polymorphism showed an association with obesity.

The polymorphisms of the MBL2 and MIF genes associated with Pediatric Cochlear Implant Patients.

Objectives: Mannose-binding lectin and macrophage migration inhibitory factor gene polymorphisms are associated with several acute/chronic autoimmune or inflammatory diseases. The aim of this study was to investigate if there was any association between mannose-binding lectin 2 (MBL2) and macrophage migration inhibitory factor (MIF) gene polymorphisms and profound congenital sensorineural hearing loss in children who underwent cochlear implantation.

Methods: A total of 62 patients with congenital hearing loss and 80 age- and sex-matched healthy controls were evaluated for codon 54 A/B polymorphisms in MBL2 and the-173 G/C polymorphism in MIF by using the polymerase chain reaction and restriction fragment length polymorphism method.

Childhood obesity and the role of dopamine D2 receptor and cannabinoid receptor-1 gene polymorphisms.

Aims: The dopaminergic and endocannabinoid systems are involved in regulation of feeding behavior. The aim of the study is to examine the possible relation between polymorphisms of the dopamine D2 receptor (DRD2) and cannabinoid receptor-1 (CNR1) genes and childhood obesity.

Mannose binding lectin and macrophage migration inhibitory factor gene polymorphisms in Turkish children with cardiomyopathy: no association with MBL2 codon 54 A/B genotype, but an association between MIF -173 CC genotype.

Myocardial inflammation is one of the commonest mechanisms in cardiomyopathy (CMP). Mannose binding lectin (MBL) is a key molecule in innate immunity, while macrophage migration inhibitory factor (MIF) is a constitutive element of the host defenses. We investigated the possible association between polymorphisms of MBL2 and MIF genes and CMP in Turkish children.
