Analysis of Promyelocytic Leukemia in Human Embryonic Carcinoma Stem Cells During Retinoic Acid-Induced Neural Differentiation
Background: Promyelocytic leukemia protein (PML) is a tumor suppressor protein that is involved in myeloid cell differentiation in response to retinoic acid (RA). In addition, RA acts as a natural morphogen in neural development. Objectives: This study aimed to examine PML gene expression in different stages of in vitro neural differentiation of NT2 cells, and to investigate the possible role o...
متن کاملAcute Promyelocytic Leukemia: All-Trans-Retinoic Acid Era
Acute promyelocytic leukemia (APL) is highly curable with the combination of all retinoic acid (ATRA) and anthracycline based chemotherapy, but the percentage of early deaths remains high. In the present study, we report the clinical, immunophenotypi molecular characteristics and outcome of APL patients diagnosed and treated in various Hospitals of Greece and Cyprus. We describe the data of nin...
متن کاملGene expression profiling during all-trans retinoic acid-induced cell differentiation of acute promyelocytic leukemia cells.
Using cDNA microarrays we determined the gene expression patterns in the human acute promyelocytic leukemia (APL) cell line NB4 during all-trans retinoic acid (ATRA)-induced differentiation. We analyzed the expression of 12,288 genes in the NB4 cells after 12 hours, 24 hours, 48 hours, 72 hours, and 96 hours of ATRA exposure. During this time course, we found 168 up-regulated and more than 179 ...
متن کاملGranulocytic differentiation of human NB4 promyelocytic leukemia cells induced by all-trans retinoic acid metabolites.
The metabolism of all-trans retinoic acid (ATRA) has been reported to be partly responsible for the in vivo resistance to ATRA seen in the treatment of human acute promyelocytic leukemia (APL). However, ATRA metabolism appears to be involved in the growth inhibition of several cancer cell lines in vitro. The purpose of this study was to evaluate the in vitro activity of the principal metabolite...
متن کاملStat1 is induced and activated by all-trans retinoic acid in acute promyelocytic leukemia cells.
Treatment of freshly isolated acute promyelocytic leukemia (APL) cells and the myelogenous leukemia cell lines, NB4, HL-60, and U937, with all-trans retinoic acid (ATRA) results in a remarkable elevation in the amounts of Stat1 alpha and Stat2 proteins. Stat1 alpha protein levels are augmented by ATRA as a consequence of elevated amounts of the corresponding transcripts. The retinoid increases ...
