background and objectives: phospholipases are a group of enzymes that breakdown phospholipid molecules producing second products. these second products play a diverse role in the cell such as signal transduction and digestion in humans. in this study, the effect of phospholipids on the expression of pld genes of a. fumigatus was investigated. the pld genes of this fungus were also investigated ...
Salinity is one of the most important abiotic stresses that decrease crop production. Transcription factors (TFs) are prominent regulators in plant responses to abiotic stress. In the present study, the expression pattern of four salt-induced genes encoding transcription factors, namely, MYB, RF2, GTF, and ARID was studied in response to salt stress (sodium chloride) and recovery conditions. Th...
Background & Aims: Breast cancer is a threatening disease in females and is the second common cancer among women after lung cancer. The aim of this research is to bioinformatically and experimentally evaluate the effect of methotrexate (MTX) on the expression of HMGA2 and SMARCA5 genes in the MTX treated 4T1 cancer cell line. Materials & Methods: To perform this study, initially microarray dat...
Background and Aim: Psoriasis is a chronic inflammatory skin disease, influenced by genetic and immune-based factors that is associated with skin inflammation. Aloe vera gel is traditionally used to treat skin diseases including psoriasis. Methods: In this study, ethanolic extract of aloe vera gel was evaluated for its anti-inflammatory and antioxidant activity in skin-derived A431 cells....
Background: Zearalenone (ZEA) is known as a nonsteroidal oestrogenic mycotoxin produced by different species of Fusarium fungi. ZEA is known for its competitive effects with the natural 17-β estradiol to bind with the specific binding sites of the estrogen receptors (Ers). On the other hand, the cyclin family (especially cyclin D1) and E2F1 genes are the checkpoint genes involved in cell cycle....
Introduction: Early diagnosis of breast cancer and the identification of effective genes are important issues in the treatment and survival of the patients. Gene expression data obtained using DNA microarray in combination with machine learning algorithms can provide new and intelligent methods for diagnosis of breast cancer. Methods: Data on the expression of 9216 genes from 84 patients across...
septoria tritici blotch (stb), caused by the ascomycete fungus mycosphaerella graminicola (asexual stage: septoria tritici), is one of the most important foliar diseases of wheat. in this research, quantitative expression analysis of five candidate genes for the induction of resistance to stb (pr-1, bsi, msr, per, and ppi) was conducted in the wheat cultivars ‘seri 82’ (susceptible) and ‘fronta...
Introduction: Cancer, the uncontrolled division of cells, occurs because of environmental factors and genetic disorders. Breast cancer is the most common cancer and the second leading cause of cancer death in women. Four categories of key genes, including oncogenes, tumor suppressor genes, repairing genes, and programmed– cell death genes, contribute to cancer development. Bromoacetic acid is a...
introduction: multiple sclerosis is a chronic inflammatory disease of central nervous system. the etiology of ms is slightly known, but genetic and environmental factors are reported. vitamin d regulates gene expression and affects target cell functions. the aim of this study was to investigate the expression variation of il-2 and il-4 genes under vitamin d supplementation in patients with mult...
Objective(s): Stem cell differentiation into different cell lineages depends upon several factors, cell cycle control elements and intracellular signaling elements, including P15INK4b and P16INK4a genes. Epigenetics may be regarded as a control mechanism which is affected by these factors with respect to their promoter structure. Materials and Methods: The CD34 + cord blood s...
