uring the systemic inflammatory response, circulating cytokines interact with the vascular endothelium, resulting in activation and nuclear accumulation of the nuclear transcription factor, nuclear factor kappa B (NF ␬ B). In turn, NF ␬ B transactivates relevant proinflammatory genes, resulting in an amplification of the inflammatory response. Because this(More)
Aberrant DNA methylation is a critical epigenetic process involved in gene expression of tumor cells. Diverse DNA methyltransferase inhibitors are being studied as potential anticancer drugs, and there is interest in developing novel and more effective DNMTIs. We evaluated zebularine, a stable and low-toxic cytidine analog, effects on human promyelocytic(More)
DNMT inhibitors are promising new drugs for cancer therapies. In this study, we have observed the antileukemic action of two diverse DNMT inhibitors, the nucleoside agent zebularine and the non-nucleoside agent RG108, in human promyelocytic leukemia (PML) HL-60 cells. Zebularine but not RG108 caused dose- and time-dependent cell growth inhibition and(More)
Human amniotic fluid stem cells have become an attractive stem cell source for potential applications in regenerative medicine and tissue engineering. The aim of this study was to characterize amniotic fluid-derived mesenchymal stem cells (AF-MSCs) from second- and third-trimester of gestation. Using two-stage protocol, MSCs were successfully cultured and(More)
Human amniotic-fluid-derived mesenchymal stem cells (AF-MSCs) are interesting for their multilineage differentiation potential and wide range of therapeutic applications due to the ease of culture expansion. However, MSCs undergo replicative senescence. So far, the molecular mechanisms that underlie fetal diseases and cell senescence are still poorly(More)
Epigenetic regulation is known to affect gene expression, and recent research shows that aberrant DNA methylation patterning and histone modifications may play a role in leukemogenesis. In order to highlight the co-operation of epigenetic mechanisms acting during the latter process it is important to clarify their potential as biomarkers of granulocytic(More)
