human diploid fibroblast cells produce a spectrum of necessary growth factors and extracellular matrix (ecm) components essential for growth and proliferation of a variety of other cell types. in this study, the effect of five human embryonic fibroblast cell lines, isolated from liver, lung, skin and foreskin tissues, was investigated. a coculture system analyse was employed to cloning efficien...

Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosph...

background: the omega-3 (ω-3) fatty acid eicosapentaenoic acid (epa) is currently used in the clinic as a nutritional supplement to improve infertility, particularly in women with polycystic ovarian syndrome (pcos).objective: the present study was designed to investigate the effect of epa on insulin-like growth factor 1 (igf-1) and cyclooxygenase 2 (cox-2) gene expression in primary cultured gr...
