background: trichomonas vaginalis is the agent of urogenital tract infection that causes human trichomoniasis with some serious health complications. more understanding about genetic features of the parasite can be helpful in the study of the pathogenesis, drug susceptibility and epidemiology of the infection. for this end,we conducted analysis of the actin gene of t. vaginalis by applying the ...

Introduction: Beta-actin is a housekeeping gene, which is used as an internal standard in various biological studies. Recently, it was reported that the expression of commonly used housekeeping genes including ß–actin changes in disease states or under certain experimental conditions. Based on the reports about the effects of sex hormones on the expression of the ß- actin gene, in this study...

Actins play essential roles in cellular morphogenesis. In mice, the t-actin 1 and 2 genes, which encode actin-like proteins, are specifically expressed in haploid germ cells. Both T-ACTIN 1/ACTLB and T-ACTIN 2/ACTL7A have also been cloned as orthologous genes in humans; they are present on chromosome 9q31.3 as intronless genes. Defects of germ cell-specific genes can introduce infertility witho...

Abstract The monomeric (G-actin) and polymer (F-actin) forms of actin play important role in muscle development contraction, cellular motility, division, transport processes. Leiomodins 1–3 (Lmod1–3) are crucial for the sarcomeres. Unlike tropomodulins that localize only at pointed ends, striated specific Lmod2 shows diffuse distribution along entire length thin filaments. G-actin-binding profi...

over the past few decades, actin’s presence in the nucleus has been demonstrated. actin is a key protein necessary for different nuclear processes. although actin is well known for its functional role in dynamic behavior of the cytoskeleton, emerging studies are now highlighting new roles for actin. at the present time there is no doubt about the presence of actin in the nucleus. a number of st...

background: the aim of this study was to identify the trichomonas vaginalis strains/haplotypes based on identifying their probable variations in asymptomatic patients referred to tabriz health centers, northwestern iran. methods: sampling was taken from 50-suspected women to t. vaginalis in northwestern iran. the obtained samples were smeared and cultured. fifty dna samples were extracted, ampl...

Background Bone marrow and adipose tissue are two main sources of mesenchymal stem cells (MSCs). Some of studies suggest that there are some differences in gene expression profile of MSCs-derived from various tissues. To investigate gene expression profile by qRT-PCR, an appropriate reference gene with stable expression level should be chosen for normalizing data.  This study was designed to e...

Actin and spectrin are important constituents of axonal cytoskeleton. Periodic actin-spectrin structures found in dendrites, initial segment axon, main axon. Actin-spectrin periodicity has been hypothesized to be manipulating the axon stability mechanical behavior. Several experimental computational studies have performed focusing on behavior actin, spectrin, network. However, most actin focus ...

The actin cytoskeleton plays critical roles in numerous cellular events and functions, its spatiotemporal dynamics are maintained regulated by several cofactor proteins. MISP/Caprice is a recently reported actin-bundling protein that also involved the progression of mitosis. In this study, we investigated how actin-regulatory function MISP modulated phosphorylation. A series mutation studies de...
