[ 1 ] - Association between HIC1 and RASSF1A Promoter Hypermethylation with MTHFD1 G1958A Polymorphism and Clinicopathological Features of Breast Cancer in Iranian Patients

Background: Ras-associated domain family 1 (RASSF1A) and hypermethylated in cancer (HIC1) genes are methylated more frequently in breast cancer. Genetic factors that alter the DNA methylation levels in normal and tumor tissues could therefore influence the susceptibility to this tumor phenotype. Objective: We determined the frequency of aberrant methylation of HIC1 and RASSF1A gene promoters an...

[ 2 ] - The Study of DNA Methyltransferase-3B Promoter Variant Genotype among Iranian Sporadic Breast Cancer Patients

Background: DNA methyltransferase-3B (DNMT3B) is an important enzyme responsible for maintaining the DNA methylation pattern in eukaryotic cells. In this study we have investigated the correlation between the 46359C→T polymorphism in the DNMT3B gene and the risk of breast cancer incidence among sporadic breast cancer patients in Fars Province, Southern Iran.Methods: In this case-control study, ...

[ 3 ] - Optimal Electroporation Condition for Small Interfering RNA Transfection into MDA-MB-468 Cell Line

Background: Electroporation is a valuable tool for small interfering RNA (siRNA) delivery into cells because it efficiently transforms a wide variety of cell types. Since electroporation condition for each cell type must be determined experimentally, this study presents an optimal electroporation strategy to reproducibly and efficiently transfect MDA-MB 468 human breast cancer cell with siRNA. ...

[ 4 ] - Hypermethylation of E-Cadherin and Estro-gen Receptor- Gene Promoter and Its Association with Clinicopathological Features of Breast Cancer in Iranian Patients

Background: Aberrant methylation of cytosine-guanine dinucleotide islands leads to inactivation of tumor suppressor genes in breast cancer. Tumor suppressor genes are unmethylated in normal tissue and often become hypermethylated during tumor formation, leading to gene silencing. We investigated the association between E-cadherin (CDH1) and estrogen receptor-α (ESRα) gene promoter methylation a...
