Background: 6-thioguanine (6-TG) is one of the thiopurine drugs with successful use in oncology, especially for acute lymphoblastic leukemia (ALL). 6-TG is proposed to act as an epigenetic drug affecting DNA methylation. The aim of this study was to clarify the effect of 6-TG on the proliferation, viability and expression of genes coding for the enzymes DNA methyltransferase 3A and DNA methyltr...

Breeding programs strategies depends on genetical mechanism of selection traits. In the present research, generation mean analysis with joint scaling test was performed to determine the gene action. F1, F2 and F3 generations, derived from Roushan and Kavir cross along with their parents were sown in a partial Lattice design with two replications under stress condition at the research field of S...

Background: Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS) that is characterized by inflammation, demyelination and axonal injury. Although the etiology of MS disease is still unknown, many studies suggest that immune system dysfunction plays an important role in the pathogenesis of this disease. The serotonin serves as a mediator between CNS and the immune sys...

Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....

Background and purpose: Long QT syndrome is a heart arrhythmia identified by prolongation of the QT interval which is a cause of sudden cardiac death in young individuals. In most cases, abnormalities in heart repolarization are reasons of prolongation of action potential and arrhythmia. The activity of ion channels is sensitive to ATP level, therefore, mitochondrial disorders are considered...
