Alterations in cytosine-5 DNA methylation are frequently observed in most types of human cancer. Although assays utilizing PCR amplification of bisulfite-converted DNA are widely employed to analyze these DNA methylation alterations, they are generally limited in throughput capacity, detection sensitivity, and or resolution. Digital PCR, in which a DNA sample is analyzed in distributive fashion...

Viral infections are often accompanied by pulmonary microvascular leakage and vascular endothelial dysfunction via mechanisms that are not completely defined. Here, we investigated the effect of the Toll-like receptor 3 (TLR3) ligand polyinosinic-polycytidylic acid [Poly(I:C)], a synthetic analog of viral double-stranded RNA (dsRNA) commonly used to simulate viral infections, on the barrier fun...

many factors including genetic, environmental, and acquired are involved in breast cancer development across various societies. among all of these factors in families with a history of breast cancer throughout several generations, genetics, like predisposing genes to develop this disease, should be considered more. early detection of mutation carriers in these genes, in turn, can play an import...

lentinan a polysaccharide from medicinal mushroom i.e lentinus, has been known to have anticancer properties. telomerase activity is not observed in normal healthy cells, whereas in cancerous cells telomerase expression is high. telomerase represents a promising cancer therapeutic target. we investigated the inhibitory effect of lentinan on telomerase reverse transcriptase gene (htert) which is...

lentiviral vectors are promising gene delivery tools capable of transducing a variety of dividing and non-dividing cells, including pluripotent stem cells which are refractory for transduction by murine retroviruses. although there is a growing debate on the safety of lentiviral vectors for gene transfer, in particular for those derived from human immunodeficiency viruses, type one (hiv-1) and ...

abstract background: schizophrenia is a severe mental disorder and numerous genes and loci are beleived to be involved in this disease. recent studies have reported a strong genetic association between dtnbp1 (dystrobrevin-binding protein 1) gene variants and schizophrenia. methods: in this research, we used a case-control study to establish the possible association between the p1635 (rs3213207...

the engineering of transgenic canola (brassica napus l. ) to make tolerance to the broad-spectrum herbicide, glyphosate, is one of the most effective approaches for weed management. glyphosate inhibits the enzyme epsps (5-enolpyruvylshikimate-3-phosphate synthase) enzyme which functions in the shikimate pathway and has a key role in biosynthesis of aromatic amino acids required for survival of ...

this study was performed to investigate two polymorphic sites from cyp19 gene (pvuii and mspi) and one polymorphic site from erα gene (snabi) in four cattle breeds including mazandarani, taleshi, sistani and simmental. in overall 278 samples for cyp19 and 206 samples for erα marker sites were genotyped using polymerase chain reactionsingle-strand conformation polymorphism (pcr-rflp) procedure. ...
