Increased Expression of CYP2E1 Gene in Gastric Cancer May be a Molecular Marker for Mazandaran Province Population
Authors
Abstract:
Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics probably involved in gastric cancer incidence through activation of procarcinogens. North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds, including agricultural pesticides, are massively used. In this report, we quantitatively compared CYP2E1 gene expression between tumoral and nontumoral-marginal tissues of gastric cancer patients as well as normal healthy gastric tissues by real-time PCR. Results showed that CYP2E1 gene cDNA copy numbers were relatively increased in tumoral group vs. nontumoral-marginal and normal healthy groups. Comparison of means DDCT by Dunkan’s test statistically verified significant differences of cyp2E1 cDNA copy numbers between tumoral and healthy tissues (P=0.0018). It seems that the increased CYP2E1 gene expression may be associated with increased risk for gastric cancer. So, we recommended that CYP2E1 gene expression may be an appropriate molecular marker to determine individual sensitivity to gastric cancer and also for designing cancer prevention programs.

MAP3K1 May be a Promising Susceptibility Gene for Type 2 Diabetes Mellitus in an Iranian Population
Considering that MAPK (mitogen- activated protein kinase) signaling pathway has an important role in the progression of inflammatory cytokine secretion in type 2 diabetes mellitus (T2DM), we have recently investigated the reported genetic polymorphism from genome wide association study in MAP3K1 (mitogen-activated protein kinase kinase kinase 1) in diabetes as an important member of MAPK signal...

Background: North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds especially agricultural pesticides are massively used. Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics. The polymorphic nature of cyp2E1 gene control elements is associated with interindividual differences...
full textExpression of Survivin in the Formalin-Fixed, Paraffin-embedded Specimens of Human Osteosarcoma May Be Used as a Diagnostic Marker
Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...
full textEvaluation of Nucleostemin Gene Expression as a New Molecular Marker in Breast Tumors
Background & Aims: Nucleostemin is one of the stem cell enriched proteins which encodes a novel nucleolar GTP-binding protein found at high levels in the adult and embryonic stem (ES) cells but not in terminally differentiated cells. It is also expressed in tumor cell lines as well as in the several types of human cancers. Due to the increasing rate of breast cancer in recent years, in the pres...

Objective(s): Nowadays, ionizing radiation (IR) has a significant contribution to the diagnostic and therapeutic medicine, and following that, health risks to individuals through unexpected exposure is greatly increased. Therefore, biological and molecular technology for estimation of dose (biodosimetry) is taken into consideration. In biodosimetry methods stimulation ...
