Abstract:
Cytogenetically normal acute myeloid leukemia (CN-AML) accounts for 40%-50% of all AML cases. Despite advances in understanding the molecular pathophysiology of CN-AML, its clinical outcome remains unsatisfactory and unpredictable. To investigate its clinical implication in CN-AML, we measured the expression of prohibitin 2 (PHB2) using immunohistochemical staining (IHCS) of paraffin-embedded bone marrow sections from 134 CN-AML patients. IHCS results were semi-quantitatively scored. Clinical outcome was analyzed in comparison with other prognostic markers, including NPM1 polymorphism and FLT3 internal tandem duplication, and WT1 and BAALC mRNA expression. Except for BAALC mRNA expression, the known molecular markers showed no prognostic effect in the CN-AML patients. PHB2 protein overexpression was significantly associated with adverse prognosis in CN-AML patients. The PHB2 protein expression status may serve as an independent prognostic indicator in CN-AML.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
