Associations of galectin-3 expression and LGALS-3 (rs4652) gene variant with coronary artery disease risk in diabetics.

Background: Galectin-3 protein encoded by lectin galactoside-binding soluble-3 (LGALS-3) gene is an important genetic factor in type 2 diabetes mellitus (T2DM) and its cardiovascular obstacles in various populations. We aimed to elicit the pro-inflammatory effect of galectin-3 as determined by interleukin-6 (IL-6) serum levels and to explore the relationship between galectin-3 (LGALS-3 rs4652) gene variant and its expression levels with coronary artery disease (CAD) risk among T2DM Egyptian patients.

Methods: 112 lean subjects were compared to 100 T2DM without CAD and 84 T2DM with CAD.

Gene Polymorphism and Susceptibility to Bronchial Asthma in Children: A Single-Center Study.

Interleukin-10 (IL-10) is the key regulator of immune responses preventing the undesirable exaggerated ones. Genetic variation in the promoter region of may influence its serum level and contribute to susceptibility to bronchial asthma in children. This is a case-control study including 100 patients and 100 healthy control children who had undergone skin prick test, estimation of total IgE and serum level of IL-10 by enzyme-linked immunosorbent assay, and polymerase chain reaction-restriction fragment length polymorphism for gene polymorphism.

E670G (rs505151) Variant and Coronary Artery Disease Risk Among Diabetics.

Proprotein convertase subtilisin/kexin type 9 () is an enzyme in the family of proprotein convertases implicated in lipid metabolism and is a significant genetic risk factor in cardiovascular diseases among various populations. This study explored the correlation between the alleles of the rs505151 (E670G) locus of the gene and its expression levels with coronary artery disease (CAD) risk in Egyptian patients with type 2 diabetes mellitus (T2DM). A case-control study was performed on 112 lean subjects compared to 100 T2DM patients without CAD and 84 T2DM patients with CAD to investigate the relationships among expression levels, the E670G (rs505151) gene variant, lipid concentrations, and CAD risk in an Egyptian diabetic population.

Clinical implication and prognostic significance of FLT3-ITD and ASXL1 mutations in Egyptian AML patients: A single-center study.

Background: Both Fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) and Additional Sex Comb-like 1 (ASXL1) mutations are frequent and early genetic alteration events in acute myeloid leukemia (AML) patients. These genetic alterations may be associated with an unfavorable prognosis.

Objective: Up to our knowledge, this is the first study performed to evaluate the clinical implication and prognostic significance of FLT3-ITD and ASXL1 mutations and their coexistence on the outcome of Egyptian AML patients.

piRNA-823 Is a Unique Potential Diagnostic Non-Invasive Biomarker in Colorectal Cancer Patients.

Early detection of colorectal cancer (CRC) is the most important factor in deciding its prognosis, so the need to develop an accurate screening test is a must. P-element induced wimpy testis (PIWI) RNA-823 (piR-823) is one of the first piRNAs recognized to be linked to malignancy. We aimed to investigate the expression levels of piR-823 in both serum and tissues of colorectal cancer patients and the ability to use its serum level as a non-invasive diagnostic biomarker to detect colorectal cancer.

MiRNA 34-a regulate SIRT-1 and Foxo-1 expression in endometriosis.

Purpose: The role of the Sirutin 1 (SIRT1) and MicroRNA-34 a (miR-34a) in endometriosis and the extent to which the miR-34a/SIRT1/p53 signaling pathway is involved in its pathogenesis is unclear, so we aimed to investigate the expression of miRNA 34-a, SIRT1, Forkhead boxO (FoxO-1), p53 and other apoptotic markers in endometrial tissue of women with endometriosis in order to better understand their role and the mechanisms of their actions in the pathogenesis of such disease and if it is related to apoptosis or not.

Methods: Ectopic and eutopic endometriotic tissues were collected from seventy women with endometriosis while normal endometrial tissues were obtained from 40 fertile women without endometriosis and then gene expression of SIRT-1, miR-34a,p53, Bax, Bcl-2, Bcl-xL and FoxO-1 were measured using RT-PCR.

Results: We detected that SIRT-1 and Bcl-xL genes expressions was significantly up-regulated while miRNA34-a,p53, Bax, Bcl-2 and FoxO-1 were down-regulated in endometrial tissue of endometriotic patients compared to that of those without endometriosis.

Relationship Between Heat Shock Protein Expression and Obesity With and Without Metabolic Syndrome.

Obesity is considered a chronic inflammatory disease in which the physiological mechanism responsible for reducing inflammation is weakened, prompting low-grade inflammation throughout the body. One of the key stress response systems that is dysregulated in obesity is the heat shock response, which is a critical defense mechanism that is activated in stressful conditions. Obesity is primary to metabolic syndrome (MetS) as it appears to lead to the increase in other MetS risk factors.

Role of MicroRNA 126 in screening, diagnosis, and prognosis of diabetic patients in Egypt.

MicroRNAs (miRNAs), family of non-coding small RNAs, play a vital role in the regulation of blood glucose level. We aimed to investigate the relation of serum miRNA-126 expression with impaired glucose tolerance as well as type 2 diabetes mellitus (T2DM) patients with and without complications. One hundred healthy controls, eighty-six patients with IGT, and one hundred patients with T2DM were recruited in this study.

MicroRNA-199b expression level and coliform count in irritable bowel syndrome.

Irritable bowel syndrome (IBS) is a common intestinal disorder. The pathophysiology of IBS may involve an altered intestinal microbiota. Recent studies have shown that alterations in microRNA (miRNA) levels have affected IBS and its subtypes.

Adipose-derived mesenchymal stem cells modulate the immune response in chronic experimental autoimmune encephalomyelitis model.

Multiple sclerosis (MS) is an autoimmune inflammatory neurodegenerative disease of the central nervous system (CNS) that disrupts the myelin sheath, leading to dysfunction of the brain and spinal cord. No curative treatment is known for MS. Mesenchymal stem cells, through their immunomodulatory effects, represent a promising therapeutic approach for MS.

Association between δ-aminolevulinate dehydratase G177C polymorphism and blood lead levels in brain tumor patients.

As the δ-aminolevulinic acid dehydratase () G177C polymorphism affects the toxicokinetics of lead in the body, and the corresponding exposure to lead may increase the risk of adult brain tumors, we hypothesize that there is a possible association of the G177C genotype and the risk of brain tumors in human. Therefore, the aim of the present study was to clarify the role of the ALAD enzyme gene polymorphism at position G177C in the pathogenesis of brain tumors and its correlation to lead exposure. The gene polymorphism at position G177C was genotyped using the polymerase chain reaction with restriction fragment length polymorphism method and measured the blood lead level by atomic absorption in 81 brain tumor patients and compared the results with 81 controls.

Association of FcγRIIB and FcγRIIA R131H gene polymorphisms with renal involvement in Egyptian systemic lupus erythematosus patients.

Identification of the genetic basis of systemic lupus erythematosus (SLE) may contribute to the discovery of effective drugs before renal involvement. Our aim of this study was to estimate the association between Fc gamma receptor (FcγR) polymorphisms and SLE and renal involvement in Egyptian patients. FcγRIIB and FcγRIIA R131H gene polymorphisms were genotyped in 180 Egyptian adults.

CD14 tobacco gene-environment interaction in atopic children.

Studying gene-environment interactions may elucidate the complex origins of atopic diseases.
