Background: B. thetaiotaomicron is introduced as a candidate for the next generation of probiotics. TLR2, 4 play an important and necessary role in activating and modulating the innate immune system after exposure to bacteria in the intestine. This study aimed to investigate the effect of B. thetaiotaomicron and its derivatives on the alteration of the tlr2 and tlr4 gene expression. Materials ...
Background: Colorectal cancer (CRC) is the fourth leading cause of cancer-caused death around the world. Reports of the unnecessary transcription of family genes of the fibroblast growth factor in several types of cancer indicate the role of these factors in tumorgenesis and progression of cancer. Therefore, the level of FGF11 transcription was evaluated in colorectal cancer tumor tissues relat...
SExtended Abstract Introduction and Objective: Small grain cereals such as wheat, are affected by types of destructive environmental factors such as abiotic and biotic stresses that severely reduce crop yields. To cope with these conditions, transcription factors cause plant resistance to these stresses by activating or suppressing the expression of genes involved in the resistance responses....
Background: Pomegranate fruit (Punica granatum L.) is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. Although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by R2R3-MYB transcription factors, little is known about the regulation and role of MYB in anthocyanin pathway of pomegranate. Objectives: The present st...
Increasing drought tolerance, especially in rice, which is one of the most important crops in Asia, is necessary. Transcription factors are specific sequence DNA-binding proteins that are capable of activating or suppressing transcription. These proteins regulate gene expression levels by binding to cis regulatory elements in the promoter of target genes to control various biological processes ...
introduction cellular processes can be controlled by induction or repression of gene expression by introduction of exogenous genes and rna interference (rnai), respectively. however, the use of recently-developed specific dna-binding transcription factors offer various advantages when compared to the exogenous gene introduction and rnai for up or down regulation of gene expression. sox2 gene en...
Background: Stimulation of collateral artery growth (arteriogenesis) and/or capillary network growth (angiogenesis) would be beneficial to the patients with myocardial infarction. To understand the central role of vascular endothelial growth factor (VEGF) in biological angiogenesis, we performed molecular analysis of the VEGF gene in patients afflicted with acute myocardial infarction (AMI). Me...
background: stimulation of collateral artery growth (arteriogenesis) and/or capillary network growth (angiogenesis) would be beneficial to the patients with myocardial infarction. to understand the central role of vascular endothelial growth factor (vegf) in biological angiogenesis, we performed molecular analysis of the vegf gene in patients afflicted with acute myocardial infarction (ami). ...
The flowering process in plants proceeds through the induction of an inflorescence meristem triggered by several pathways. Many of the genes associated with these pathways encode transcription factors of the MADS domain family. The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of flower development. The first step to understand the molecular mechanisms under the function of...
