There is a growing recognition that noncoding RNAs (ncRNA) play an important role in the regulation of gene expression. A class of small (19-22 nt) ncRNAs, known as microRNAs (miRs), have received a great deal of attention lately because of their ability to repress gene expression through a unique posttranscriptional 3'-untranslated region (UTR) mechanism. The objectives of the current study we...

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. ...

suicide is a major public health concern, with approximately one million people committing suicide world-wide each year .risk factors for suicidal behavior include, psychiatric and medical illness, impulsivity, aggression, alcohol and drug abuse specially stimulants, and  stress. neurobiological, brain mappings and biochemical studies have revealed that suicide victims experiencing a large numb...
