MYELOID NEOPLASIA Autophagy contributes to therapy-induced degradation of the PML/RARA oncoprotein

Treatment of acute promyelocytic leukemia (APL) with all-trans retinoic acid and/or arsenic trioxide represents a paradigm in targeted cancer therapy because these drugs cause clinical remission by affecting the stability of the fusion oncoprotein promyelocytic leukemia (PML)/ retinoic acid receptor alpha (RARA). The authors of previous studies have implicated the ubiquitin-proteasome pathway a...

Accelerated degradation of PML-retinoic acid receptor alpha (PML-RARA) oncoprotein by all-trans-retinoic acid in acute promyelocytic leukemia: possible role of the proteasome pathway.

Acute promyelocytic leukemia (APL) is associated with a chromosomal translocation t(15;17) and successfully differentiated by all-trans-retinoic acid (ATRA) in vivo as well as in vitro. The PML-retinoic acid receptor alpha (RARA) oncoprotein, which is generated by the translocation, blocks the differentiation, and ATRA is thought to modulate the dominant negative function of PML-RARA. However, ...

شناسایی الحاق PLZF-RARa در بیماران با ریخت شناسی لوسمی پرومیلوسیتی حاد

Background and Aim: Acute promyelocytic leukemia (APL) is associated with the t(1517) ,fusing promyelocytic leukemia (PML) and retinoic acid receptor-a (RARa) genes. This disease is uniquely sensitive to treatment with all-trans retinoic acid (ATRA) and highly responsive to conventional chemotherapy. The t(1117)(q23q21) abnormality associated with a PLZF-RARa rearrangement is the commonest of t...

The t(5;17) variant of acute promyelocytic leukemia expresses a nucleophosmin-retinoic acid receptor fusion.

We have studied an acute promyelocytic leukemia (APL) patient with a variant t(5;17)(q32;q12). This translocation fuses the gene for the nucleolar phosphoprotein nucleophosmin (NPM) to the retinoic acid receptor alpha (RARA). Two alternatively spliced transcripts are expressed, which differ in 129 bases immediately upstream of the RARA sequence. The NPM sequences contained in the shorter NPM-RA...
