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 ...

This is a report of couple with abnormal hematological indices who were investigated for α & β-thalassemia mutations. Based on CBC and capillary hemoglobin electrophoresis results, the male female subjects β α-thalassemia carriers, respectively. Multiplex-Gap-PCR Sanger sequencing techniques used identification mutations β-globin genes. The DNA test showed presence c.315 + 1 G > A mutati...

Quantitative real-time PCR (RT-qPCR) has become an accurate and widely used technique to analyze expression levels of selected genes. It is very necessary to select appropriate reference genes for gene expression normalization. In the present study, we assessed the expression stability of 11 reference genes including eight traditional housekeeping genes and three novel genes in different tissue...

Objective(s): Transforming growth factor alpha (TGF-α) has been shown to modulate the gastric acid secretion. Therefore, the aim of the present study was to investigate the effect of sodium hydrosulfide (NaHS) on TGF-α expression in gastric mucosa in rats. Materials and Methods: Eighteen rats were randomly divided into 3 groups (6 per group). To determine the effect of NaHS on gene and protein ...

The current study aimed to elucidate the potential involvement of mitochondria-endoplasmic reticulum contact genes in pathogenesis periodontal disease by monitoring levels associated including Mitofusion 1 (MFN1) and MFN2, inositol 1,4,5-trisphosphate receptor (IP3R), chaperone glucose-regulated protein 75 (GRP75), sigma non-opioid intracellular (SIGMAR1) phosphate tensin homolog induced putati...

The genus Cercospora includes many important plant pathogenic fungi associated with leaf spot diseases on a wide range of hosts. The mainland of Iran covers various climatic regions with a great biodiversity of vascular plants, and a correspondingly high diversity of cercosporoid fungi. However, most of the cercosporoid species found to date have been identified on the basis of morphological ch...

The Tremellomycetes (Basidiomycota) contains a large number of unicellular and dimorphic fungi with stable free-living unicellular states in their life cycles. These fungi have been conventionally classified as basidiomycetous yeasts based on physiological and biochemical characteristics. Many currently recognised genera of these yeasts are mainly defined based on phenotypical characters and ar...

introduction: helicobacter pylori (h. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. the 16s rrna is a common h. pylori gene which are usually preferred for diagnosis purpose. the aim of this study was to determine the prevalence and abundance of 16s rrna in fecal samples and also evaluate correlation between the level of 16s rrna and activities of the cytokines,...

background inflammatory bowel disease (ibd) is a chronic, relapsing, inflammatory disorder of the gastrointestinal tract that includes two entities, crohn`s disease (cd) and ulcerative colitis (uc). as with other complex diseases, both genetic susceptibility and environmental factors play role in the pathogenesis of these diseases. the tumor necrosis factor α (tnf-α) gene is located in the ibd3...

brucellosis is a well-known domestic animal infectious disease, which is caused by brucella bacterium. the outer membrane protein 25 kda (omp25) gene plays an important role in simulating of tnf-α, ifn-α, macrophage, and cytokines cells. in the current study molecular cloning and expression analysis of omp25 gene for designing a subunit vaccine against brucella was investigated. amplifying the ...
