charcot-marie-tooth disease (cmt) is the most common form of inherited peripheral neuropathy. cmt is genetically and clinically heterogenous group of hereditary motor and sensory neuropathies characterized by areflexia, distal sensory loss and progressive weakness of the distal limb muscles. the x-linked cmt (cmtx) is the second most frequent form of charcot-marie-tooth disease. the dominant cm...

background: radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. however, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. in recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. the aim of the current study was to e...

800x600 years ago, it was thought that a genetic component was the fundamental cause of a number retinopathy diseases including age related macular degeneration (amd). since then, information has emerged about novel genes that contribute to various forms of amd and other retinopathies that have been eluding researchers for years. in the genetic sense, only the apoe 2 and 4 genes have been found...

introduction: monitoring the engraftment of donor cell after allogeneic blood stem cell transplantation is important for the early diagnosis of graft failure or relapse of disease. so analysis of donor chimerism has become a routine method for documentation of engraftment after allogeneic stem cell transplantation. in humans, the amelogenin gene is present on both the x and the y chromosomes. h...

Background and Aims: Tissue engineering is a relatively novel field that has been intensely developing during recent years and has shown to be excessively promising when used for cartilage regeneration. Scaffolds represent important components for tissue engineering. Materials and Methods: The Poly Lactic-Co-Glycolic Acid (PLGA) impregnated with fibrin and hyaluronic acid (HA) produce hybrid s...

The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...

Background: Different alleles of Fragile X Mental Retardation1 (FMR1) gene with separate molecular etiologies cause Fragile X Syndrome (FXS) and Fragile X-associated Tremor and Ataxia Syndrome (FXTAS). Premutation alleles with 55 to 200 repeats in the FMR1 gene lead to FXTAS. It is carried by 1 in 209 women and 1 in 430 men. FXTAS commonly appears in 50- to 70-year-old adults. Case Presentatio...

Objective(s) Nonviral vector can be an attractive alternative to gene delivery in experimental study. In spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. To determine the effective expression, the recombinant Escherichia coli lacZ genes were cloned into the different variants of pcDNA3.1 and the...

introduction: duchene/ becker (dmd/bmd) muscular dystrophy is the most frequent neuromuscular disease in children which is inherited as an x-linked recessive trait. the disease is caused by partial deletion in dystrophin gene. we developed a rapid and robust method for direct identification of female carriers of deletions and duplications in the dystrophin gene, in order to prevent the affected...
