Association of IL-6 G-174C (rs1800795) variant with the susceptibility to hepatocellular carcinoma in patients with chronic hepatitis.

Aim: An ineffective immune response resulting from dysregulation of cytokine production might encourage viral persistence and cause chronic viral hepatitis to worsen. This study examined the relationship between alterations in interleukin-6 (IL-6) levels and the IL-6 - 174 G > C (rs1800795) polymorphism, as well as how this polymorphism affects the development and progression of chronic hepatitis brought on by hepatitis B (HBV) and hepatitis C (HCV) into hepatocellular carcinoma (HCC).

Patients And Methods: Whole blood samples from 126 Egyptian patients with HCC (111 with HCV and 15 with HBV), as well as 126 age- and sex-matched healthy individuals, were used to extract DNA.

The role of polymorphic cytochrome P450 gene (CYP2B6) in B-chronic lymphocytic leukemia (B-CLL) incidence and outcome among Egyptian patients.

Cytochromes P450 (CYPs) play a prominent role in catalyzing phase I xenobiotic biotransformation and account for about 75% of the total metabolism of commercially available drugs, including chemotherapeutics. The gene expression and enzyme activity of CYPs are variable between individuals, which subsequently leads to different patterns of susceptibility to carcinogenesis by genotoxic xenobiotics, as well as differences in the efficacy and toxicity of clinically used drugs. This research aimed to examine the presence of the polymorphism and its possible association with the incidence of B-CLL in Egyptian patients, as well as the clinical outcome after receiving cyclophosphamide chemotherapy.

Association study between genetic polymorphisms in MTHFR and stroke susceptibility in Egyptian population: a case-control study.

Stroke is a major global disability cause, and genetic variables for multifactorial illnesses like stroke are crucial for precision medicine. The purpose of this study is to see if genetic variants in the MTHFR gene are associated with a higher risk of ischemic stroke among the Egyptian population. A case-control study was conducted at Mansoura University Hospital, involving 100 stroke patients and 150 healthy volunteers as the control group.

Detection of EGFR gene polymorphisms in non-small cell lung cancer Egyptian patients: a case-control study.

Background: Non-Small Cell Lung Cancer displays several genetic mutations including epidermal growth factor receptor. This study's objective was to determine if the EGFR exon19 rs121913438 and exon21 rs121434568 variations play a role in NSCLC susceptibility.

Methods: Case-control research was done at the Mansoura university oncology center including 124 NSCLC patients, and 124 healthy volunteers.

Association of CYP1A1 T3801C (rs4646903) variant with the susceptibility and progression of B-chronic lymphocytic Leukemia (B-CLL) in the Egyptian population.

Background: The frequency of hematological malignancies is increasing universally, and over the last few decades, a significant increase in the incidence of B-chronic lymphocytic leukemia (B-CLL) has been observed. Many studies have revealed the involvement of genetic predisposition along with environmental exposure to genotoxic xenobiotics in the leukemogenesis process of B-CLL. CYP1A1 is a vital member of the cytochromes P450 (CYPs) superfamily, which is involved in pro-carcinogens activation into reactive intermediates during phase I xenobiotic biotransformation.

Association of A1AT genetic polymorphism and NSCLC: a case- control study in Egyptian population.

Background: Lung cancer mortality is higher than other forms of cancer. Genetic tendencies in cancer patients have long been known. Given the link between A1ATD and numerous lung disorders, it is worth investigating if this genetic trait is linked to a higher risk of developing LC, as the lung is the most afflicted organ in individuals with severe A1ATD.

Analysis of the association of NPHS2 and ACTN4 genes polymorphism with nephrotic syndrome in Egyptian children.

Background: One of the most common kidney illnesses in developing countries is pediatric nephrotic syndrome (PNS), which is frequently associated with dyslipidemia and edema. The rapid discovery of genes related to NS has aided in the understanding of the molecular mechanics of glomerular filtration. The goal of this study is to determine the relationship between NPHS2 and ACTN4 in PNS youngsters.

Endothelin-1 RS5370 gene polymorphism in primary nephrotic syndrome: A case-control study.

Introduction: Primary nephrotic syndrome (NS) is a common glomerular disease in children. We assessed the genotypes and frequency of the rs5370 allelic variant of the EDN1 gene in children with primary NS.

Patients And Methods: We conducted a case-control study in Mansoura University Children's Hospital, Egypt between December 2015 and January 2018.

Rs-10889677 variant in interleukin-23 receptor may contribute to creating an inflammatory milieu more susceptible to bladder tumourigenesis: report and meta-analysis.

Bladder cancer (BLC) is a recurrent high-risk malignancy typified by an inherent localised chronic inflammation. IL-23-receptor (IL-23R), as a positive regulator in the priming of T helper-17 cells, is regarded a principal coordinator of inflammation-propelled neoplasia. In this article, we indented firstly to scrutinise the influence of rs10889677"A/C" SNP located in IL-23R-gene on BLC development and progression among Egyptians.

[Endothelin-1 rs5370 gene polymorphism in primary nephrotic syndrome: A case-control study].

Introduction: Primary nephrotic syndrome (NS) is a common glomerular disease in children. We assessed the genotypes and frequency of the rs5370 allelic variant of the EDN1 gene in children with primary NS.

Patients And Methods: We conducted a case-control study in Mansoura University Children's Hospital, Egypt, between December 2015 and January 2018.

Rs-1884444 G/T variant in IL-23 receptor is likely to modify risk of bladder urothelial carcinoma by regulating IL-23/IL-17 inflammatory pathway.

Bladder urothelial carcinoma (BUC) is a chronic relapsing urological malignancy, which poses a serious threat to human life. Non-resolving chronic-inflammation at the neoplastic site is associated consistently with inducing tumor-progression and poor patient outcomes. Interleukin 23 receptor (IL-23R) is a key element in T-helper 17 cell-mediated inflammatory process, that plays a critical role in orchestrating tumor-promoting inflammation.

CYP2C9 (*2&*3) and CYP2C19 (*2&*3) polymorphisms among children with nonlesional epilepsy: a single-center study.

Cytochrome (CYP) P450 enzymes are responsible for metabolism of antiepileptic drugs (AEDs), and encoded by highly polymorphic genes. A case-control study was conducted in Mansoura University Children's Hospital, Egypt including 100 children with nonlesional epilepsy (50 AEDs responders and 50 resistant cases) and 50 healthy controls. All participants were investigated for frequencies of CYP2C9 (*2&*3) and CYP2C19 (*2&*3) genotypes and alleles using polymerase chain reaction.
