conclusions this study indicated that the optimization of gene transfer increases the expression of igf-1. high concentrations of igf-1, in combination with cell therapy, have a significant effect on wound healing. results in vitro, the maximum expression of igf1 (96.95 pg/ml) in transfected fibroblast cells was 24 hours after gene transfer. in vivo, it was clear that igf-1 gene therapy caused ...

Background: In gene therapy, the use of RNA molecules as therapeutic agents has shown advantages over plasmid DNA, including higher levels of safety. However, transient nature of RNA has been a major obstacle in application of RNA in gene therapy. Methods: Here, we used the internal ribosomal entry site of encephalomyocarditis virus and the 3’ non-translated region of Poliovirus to design an en...

Abstract Diabetic cardiomyopathy increases the risk of heart failure and worsens prognosis for diabetes mellitus (DM) patients. Its development depends on many factors, including modification nitric oxide production impaired DNA repair. The goal present work was to study in vivo effects a 1,4-dihydropyridine AV-153, known as antimutagen DNA-binder, integrity, expression several proteins involve...

Background: Radiotherapy is an effective and important therapeutic method for breast cancer, but at the same time it has a radiation-induced bystander effect on normal tissue around the tumor. Repair of double-strand breaks (DSBs) by normal cells can reduce the extent of damage caused by this effect. Caveolin-1 (Cav-1) is an important regulatory molecule in cell signal transduction. However, th...

BACKGROUND Boron neutron capture reaction (BNCR) is based on irradiation of tumors after accumulation of boron compound. 10B captures neutrons and produces an alpha (4He) particle and a recoiled lithium nucleus (7Li). These particles have the characteristics of high linear energy transfer (LET) radiation and have marked biological effects. The purpose of this study is to verify that BNCR will i...

Diagnosing metastatic renal cell carcinoma (RCC) by fine-needle aspiration (FNA) can be challenging. Existing antibodies supporting a diagnosis of RCC, including CD10 and RCC-Ma, have problems with specificity and interpretation. In this report, we evaluate the use of two newer immunostains, PAX-2 and gamma-H2AX, which to our knowledge have not been studied in FNA material, in the diagnosis of ...

INTRODUCTION Low dose-rate radioimmunotherapy (RIT) using (125)I-labelled monoclonal antibodies ((125)I-mAbs) is associated with unexpected high cytotoxicity per Gy. METHODS We investigated whether this hypersensitivity was due to lack of detection of DNA damage by the targeted cells. DNA damage was measured with the alkaline comet assay, gamma-H2AX foci and the micronucleus test in p53(-/-) ...
