We have identified an intergenic transcriptional activity that is located between the human HOXA1 and HOXA2 genes, shows myeloid-specific expression, and is up-regulated during granulocytic differentiation. The novel gene, termed HOTAIRM1 (HOX antisense intergenic RNA myeloid 1), is transcribed antisense to the HOXA genes and originates from the same CpG island that embeds the start site of HOX...

Cytomegalovirus (HCMV) reactivation is found frequently after allogeneic hematopoietic stem cell transplantation (alloSCT) and is associated with an increased treatment-related mortality. Recent reports suggest a link between HCMV and a reduced risk of cancer progression in patients with acute leukemia or lymphoma after alloSCT. Here we show that HCMV can inhibit the proliferation of the acute ...

Selective targeting of the PML/RARα oncoprotein demonstrates a successful molecular targeted therapy in acute promyelocytic leukemia (APL) with a typical t(15:17) chromosomal translocation. The zinc-thiolate coordination is critical for structural stability of zinc finger proteins, including the PML moiety of PML/RARα. Based on the known interaction of redox-active selenium compounds with thiol...

The PML-RARα fusion gene disrupts the retinoic acid differentiation signal in a range of leukaemia types, promoting proliferation. We designed a shRNA to target the fusion mRNA, and the shRNA expression cassette was delivered via lentiviral transduction. Delivery of this shRNA significantly down regulated the target mRNA, with effects also evident at the protein level. When combined with ATRA a...

in order to determinate the self–incompatibility and the most suitable pollinizer for esfahan commercial quince cultivar, the effects of four different pollinizer treatments ((km1, pk2, kvd2, nb4), as self pollination and open pollination) on fruit set and quantitative and qualitative characteristics of commercial quince fruits of isfahan were studied in a randomized complete block design with ...

Retinoic acid (RA) promotes granulocytic differentiation of normal hematopoietic cells and acute promyelocytic leukemia (APL) blasts by transcriptional modulation of myeloid regulatory genes. In this study, we have identified the C/EBP homologous protein (CHOP) as a novel retinoid-responsive gene using a polymerase chain reaction (PCR)-based cDNA subtraction method. All-trans retinoic acid (ATR...
