introduction: the estrogen receptors are potential candidates in prognosis and particularly in predicting hormone response therapy in breast cancer. the aim of this study was to measure erα gene expression due to study of the association between erα expression, age and menopause of iranian women with breast cancer. methods: 21 adenocarcinoma cases with grade 2 and 10 normal samples were screene...

A robust cell envelope is the first line of defense in infectious pathogens when encountering host immune defenses. In Gram-positive bacteria, LytR-CpsA-Psr (LCP) family proteins play a major role synthesis and assembly envelope. The bacterium S. pyogenes causes wide range diseases from pharyngitis to septicemia, but involvement LytR wall this not clear. Therefore, we investigated whether pyoge...

Myogenin gene (MYoG) affects the synthesis of muscle myofibrillar growth and increase of meat production. The myostatin (MSTN) gene is identified as a specific negative regulator of skeletal muscle growth. Reduction of the expression level of MSTN throughmutation in the sequence of this gene leads to an increase of myogenesis and regeneration of muscle cells during the postnatal growing period ...

Fusarium head blight (FHB) caused by Fusarium graminearum is responsible for billions of dollars in agriculture losses. The goal of the present study was evaluation the expression of acidic chitinase, one of PR proteins, in wheat defense response against different FHB induced treatments in 'Falat' as a highly susceptible and 'Sumai3' as a tolerant cultivar. These treatments contained fungi extr...

In the post-genomic era, the ability to synthesize any arbitrary DNA sequence is increasingly in demand. A bottleneck in current gene synthesis technologies is the associated cost, due primarily to the high cost of oligonucleotides synthesis and post-synthesis sequencing. In the present paper, an improved method for low-cost gene synthesis that combines dual asymmetrical PCR and overlap extensi...

Objective: We examined the effectiveness of Hyssopus officinalis (hyssop) aqueous extract on pentylenetetrazole (PTZ)-induced acute seizures and the hippocampus iNOS (induciblenitric oxide synthases) gene expression as a potential mediator of the effects. Materials and Methods: Adult male Wistar rats were used. Tonic-clonic seizures were...

R2R3-MYB TFs represent one of the most extensive gene families in plants and play a crucial role regulating plant development, metabolite accumulation, defense responses. Nevertheless, there has been no systematic investigation into pomegranate family. In this study, 186 genes were identified from genome grouped 34 subgroups based on phylogenetic analysis. Gene structure analysis showed that Pg...

Phospholipid synthesis in the yeast Saccharomyces cerevisiae is a complex process that involves regulation by both genetic and biochemical mechanisms. The activity levels of phospholipid synthesis enzymes are controlled by gene expression (e.g., transcription) and by factors (lipids, water-soluble phospholipid precursors and products, and covalent modification of phosphorylation) that modulate ...
