Mitochondrial RNA helicase DDX28 promotes cell cycle and DNA repair programs and shapes an immunosuppressive microenvironment in acute myeloid leukemia

A mitochondrial protein linked to poor outcomes in AML may unlock new therapeutic targets at the intersection of cell metabolism and immune suppression.

Integrated bioinformatics analysis across AML cohorts identifies DDX28 (mitochondrial RNA helicase) as a novel prognostic biomarker associated with poor survival and an immunosuppressive tumour microenvironment. In vitro siRNA knockdown confirms a functional role in AML cell proliferation and migration, positioning DDX28 as a candidate therapeutic target linking mitochondrial translation to immune evasion.
