The insulin/insulin-like growth factor pathway is involved in breast and colorectal cancer (CRC) development. In the present study, we analyzed the coding region and short intron-exon borders of the insulin receptor substrate 1 and 2 (IRS‑1 and IRS‑2) genes in 12 cell lines derived from breast cancer (BC), 14 cell lines derived from CRC and 33 primary CRCs. The nucleotide variants identified in...

Using bioinformatics, putative cis-regulatory sequences can be easily identified using pattern recognition programs on promoters of specific gene sets. The abundance of predicted cis-sequences is a major challenge to associate these sequences with a possible function in gene expression regulation. To identify a possible function of the predicted cis-sequences, a novel web tool designated 'in si...

Streptococcus pyogenes or group A Streptococcus (GAS) causes ~700 million human infections each year, resulting in over 500,000 deaths. The development of a commercial GAS vaccine is hampered due to high strain and serotype diversity in different geographical regions, and the generation of cross-reactive antibodies that may induce autoimmune disease. There is an urgent need to search for altern...

This paper reports the full genome sequence of the antimicrobial-producing bacterium Geobacillus stearothermophilus DSM 458, isolated in a sugar beet factory in Austria. In silico analysis reveals the presence of a number of novel bacteriocin biosynthetic genes.

p38 Mitogen-activated protein kinase (p38 MAPK) is a protein kinase critically involved in the progress of inflammation/stress-associated diseases. Our data suggested that javamide analogues may contain strong anti-inflammation activities, but there is little information about their effects on p38 MAPK. Therefore, in this paper, the effects of thirty javamide analogues on p38 MAPK were investig...

objective: methylmalonic acidura (mma) is a rare autosomal recessive inborn error of metabolism. in this study we present a novel nucleotide change in the mutase (mut) gene of two unrelated iranian pedigrees and introduce the methods used for its functional analysis. materials and methods: two probands with definite diagnosis of mma and a common novel variant in the mut were included in a descr...

the broad consumption of antibiotics such as fluoroquinolones and the genetic adaption of opportunistic pathogenic bacteria including pseudomonas aeruginosa , has led to develop of floroquinolone-resistant strains of pseudomonas aeruginosa . thus, the aim of the present study is to reveal the types of hot spot mutations occurring in selected dna gyrase subunit a gene in fluoroquinolone-resistan...

The main purpose of this paper is to present application of hybrid (i.e. combined physical and in silico) modeling and nonlinear (fractal) biosignal analysis for improving quality of life through modeling and knowledgebased measurements in medicine.

A review on applicability of in silico methods for toxicity testing by calculation for regulatory purposes, their survey and background of QSAR (Quantitative Structure-Activity Relationships) analysis are presented.
