Increased oxidative stress can help promote carcinogenesis, including development of renal cell carcinoma. The enzyme protects low-density lipoproteins from oxidation and can be a factor in this process. PON1 Q192R and L55M paraoxonase gene polymorphisms were assessed in 60 renal cell carcinoma patients and 60 healthy controls. Genotypes were examined by PCR; the restriction enzyme AlwI was use...

Background and Aims: Ficolins are proteins that bind to carbohydrates, act as opsonins and play an important role in innate immunity. Polymorphism in ficolin-3 gene (FCN3) can lead to complement deficiency and increase the risk of some disorders such as diabetes. The aim of this study was to investigate the frequency of FCN3+1637delC as a single nucleotide polymorphism in this gene in healthy a...

Some studies have reported that angiotensin converting enzyme (ACE) and angiotensinogen (AGT) genes have been associated with hypertrophic cardiomyopathy (HCM). However, there have been inconsonant results among different studies. To clarify the influence of ACE and AGT on HCM, a systemic review and meta-analysis of case-control studies were performed. The following databases were searched to i...

Bladder cancer is the 9th most common cancer and is responsible for malignancy related death all on the world. Folate and folate related enzyme polymorphisms related to the cancer risk. The methylene tethrahydrofolate reductase (MTHFR) enzyme is folate related and association of bladder cancer and MTHFR gene. Our purpose was to assess the prevalence of MTHFR gene 677 CT and 1298 AC polymorphism...

Methylenetetrahydrofolate reductase (MTHFR) is an enzyme involved in metabolic pathways of importance for nucleotide synthesis and methylation of DNA, membranes, proteins and lipids. The MTHFR gene includes a common polymorphism (rs1801133 or C677T), which is associated with enzyme activity. The T-allele of the C677T polymorphism has been associated with earlier age at onset of schizophrenia in...

In this study we analyzed the effect of polymorphic variation of NAD(P)H: quinone oxidoreductase1 (NQO1) gene that encode enzyme which detoxifies harmful quinines and protect hematopoietic stem cells against oxidative stress. C609T polymorphism of NQO1 gene leads to loss of enzyme activity, which may be a risk factor in the etiology of specific types of hematopoietic malignancies. We analyzed C...

Tumours of the digestive system include a number malignant tumours such as oesophageal, gastric and colorectal cancers, which have highest incidence mortality rates in world. Their occurrence is related to variety factors, diet, environment genetics. As key enzyme process folate metabolism, MTHFR gene polymorphism plays an important role pathogenesis development gastrointestinal tumours. This p...

OBJECTIVE Angiotensin converting enzyme (ACE) plays an important role in a number of inflammatory and immune related disorders. This study was undertaken to investigate an association between Angiotensin converting enzyme (ACE) gene insertion- deletion (I/D) polymorphism and primary knee osteoarthritis (OA) in Kuwait and to explore a correlation between clinical subgroups of OA and ACE I/D poly...
