Activation of retinoic acid receptor-dependent transcription by all-trans-retinoic acid metabolites and isomers.
We have shown that four metabolites of all-trans-retinoic acid (ATRA) (4-oxo-, 4-OH-, 18-OH-, and 5,6-epoxy-RA) can induce maturation of NB4 promyelocytic leukemia cells (Idres, N., Benoit, G., Flexor, M. A., Lanotte, M., and Chabot, G. G. (2001) Cancer Res. 61, 700-705). To better understand the mechanism of action of ATRA metabolites and isomers, we assessed their binding to retinoic acid rec...
متن کاملAll-trans-retinoic acid: measurement
A quantitative determination of physiological levels of all-trans-retinoic acid (vitamin A acid) in human serum has been developed. A double-phase extraction of 3.5 ml of serum followed by a specific and sensitive high performance liquid chromatography procedure allowed measurement of levels down to 1 ng/ml. Serum concentrations in 37 fasting volunteers ranged from 2.7 to 4.2 ng/ml and fitted a...
متن کاملRapid Publication All-trans Retinoic Acid Modulates the Retinoic Acid Receptor-a in Promyelocytic Cells
We have recently demonstrated that all-trans retinoic acid (RA), the active metabolite of vitamin A, is an efficient alternative to chemotherapy in the treatment of acute promyelocytic leukemia (AML3). We have further shown that, in these AML3 cells, the gene of the retinoic acid receptor-a (RARa) is translocated from chromosome 17 to chromosome 15, and fused to a new gene, PLM. This results in...
متن کاملThe cellular retinoic acid binding protein I is dispensable.
The cellular retinoic acid binding proteins I and II (CRABPI and CRABPII) bind retinoic acid with high affinity, exhibit distinct patterns of expression during embryonic development, and are thought to play important roles in the RA signaling pathway. We have generated a targeted mutation of the CRABPI gene using the "hit-and-run" strategy and shown that it prevents the production of a function...

These effects have become a therapeutic objective in human cancers. In addition to these functions, ...
