The endothelial ETS transcription factor Erg plays an important role in homeostasis and angiogenesis by regulating many endothelial functions including survival and junction stability. Here we show that Erg regulates endothelial cell (EC) migration. Transcriptome profiling of Erg-deficient ECs identified ∼ 80 genes involved in cell migration as candidate Erg targets, including many regulators o...

background and objectives: phosphlipases are a group of enzymes that breakdown phosphatidylcholine (phospholipids) molecules producing second products. these produced products have a divers role in the cell like signal transduction and digestion in humans. in this research the effect of phosphatidylcholine on the expression of plc genes of a. fumigatus was studied. the plc genes of this fungus ...

Epigenetic regulation by SIRT1, a multifaceted NAD+-dependent protein deacetylase, is one of the most common factors modulating cellular processes in a broad range of diseases, including prostate cancer (CaP). SIRT1 is over-expressed in CaP cells, however the associated mechanism is not well understood. To identify whether specific microRNAs might mediate this linkage, we have screened a miRNA ...

Down syndrome (DS), with trisomy of chromosome 21 (HSA21), is the commonest human aneuploidy. Pre-leukemic myeloproliferative changes in DS foetal livers precede the acquisition of GATA1 mutations, transient myeloproliferative disorder (DS-TMD) and acute megakaryocytic leukemia (DS-AMKL). Trisomy of the Erg gene is required for myeloproliferation in the Ts(1716)65Dn DS mouse model. We demonstra...

BACKGROUND There is limited evidence that supports etiologically distinct molecular subtypes of prostate cancer, the identification of which may improve prevention. Given their antioxidant properties, we hypothesized that lycopene and tomato sauce may be especially protective against diseases harboring the common gene fusion transmembrane protease, serine 2 (TMPRSS2):v-ets avian erythroblastosi...

PURPOSE The present study was undertaken to evaluate the effect of uniform EGFP expression on retinal morphology and function. METHODS Electroretinography (ERG) was used to evaluate the recovery of scotopic a- and b-wave amplitudes after a single 137-cd.sec/m2 flash exposure. The cellular distribution of enhanced green fluorescent protein (EGFP) in the retina and its effect on retinal morphol...

introduction: g-proteins have an important role in the cell signaling of numerous receptors. the situation of g-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. here, the changes in the expression of g-protein subunits (gαi, gαs and gβ) were evaluated in hyperglycemic situation of pc12 cells as a cellular model...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

asthma is a chronic inflammatory disorder of the airways. the stress is a factor for asthma which indicates a disorder in the function of communicational mediators of nervous and  immunological systems  such  as  neurotransmitters.  a  study  indicated  that  blood serotonin concentration increases in asthmatic patients. other study indicates that one kind of the serotonin  receptors, named 5ht...
