MOTIVATION The interactions among proteins and the resulting networks of such interactions have a central role in cell biology. Aligning these networks gives us important information, such as conserved complexes and evolutionary relationships. Although there have been several publications on the global alignment of protein networks; however, none of(More)
BACKGROUND Hepatitis C virus (HCV) has been known as a major cause of hepatocellular carcinoma (HCC) worldwide. However, the distinct molecular mechanisms underlying the effects of HCV proteins on the HCC progression have remained unclear. OBJECTIVES In the present study, we studied the possible role of HCV in the HCC initiation and invasion using(More)
Phytase efficiently catalyzes the hydrolysis of phytate to phosphate; it can be utilized as an animal supplement to provide animals their nutrient requirements for phosphate and to mitigate environmental pollution caused by unutilized feed phosphate. Owing to animal feed being commonly pelleted at 70 to 90 °C, phytase with a sufficiently high thermal(More)
Homotetrameric β-xylosidase from Selenomonas ruminantium (SXA) is one of the most efficient enzymes known for the hydrolysis of cell wall hemicellulose. SXA shows a rapid rate of activity loss at temperatures above 50°C. In this study, we have introduced two inter-subunit disulfide bridges with one point mutation. Lys237 was chosen to be replaced with(More)
MOTIVATION Molecular dynamics (MD) simulations have had a profound impact on studies of membrane proteins during past two decades, but the accuracy of MD simulations of membranes is limited by the quality of membrane models and the applied force fields. Membrane models used in MD simulations mostly contain one kind of lipid molecule. This is far from(More)
Aldehyde oxidase (AO), a cytosolic molybdenum-containing hydroxylase, is predominantly active in liver and other tissues of mammalian species and involved in the metabolism of extensive range of aldehydes and nitrogen-containing compounds. A wide range of natural components including polyphenols are able to interfere with AO-catalyzed reactions. Polyphenols(More)
More than 140 mutations in the SOD1 gene cause aggregation of the affected protein in familial forms of amyotrophic lateral sclerosis (fALS) which is a fatal progressive neurodegenerative disorder selectively affecting motor neurons. The causes of motor neuron death in ALS are poorly understood in general, but for fALS, aberrant oligomerization of SOD1(More)
Angiogenesis is a hallmark of various pathological conditions and is controlled by a variety of angiogenic factors. Blockade of vascular endothelial growth factor (VEGF) as the most pivotal stimulator of angiogenesis offers a promising therapeutic approach for some diseases, typically cancer. In the present study, a heterodimeric antagonistic VEGF was(More)
BACKGROUND Recent studies have shown that the high mortality of patients with colorectal cancer (CRC) is related to its ability to spread the surrounding tissues, thus there is a need for designing and developing new drugs. OBJECTIVE Here, we proposed a combinational therapy strategy, an inhibitory peptide in combination with miRNA targeting, for(More)
Protein tertiary structure prediction (PSP) is one of the most challenging problems in bioinformatics. Different methods have been introduced to solve this problem so far, but PSP is computationally intensive and belongs to the NP-hard class. One of the best solutions to accelerate PSP is the use of a massively parallel processing architecture, such(More)
