Nucleophosmin 1 messenger RNA (NPM1 mRNA) (NPM1 mRNA)

Nucleophosmin 1 (NPM1) messenger RNA (mRNA) is the primary transcript of the NPM1 gene, which encodes a multifunctional nucleolar phosphoprotein essential for ribosome biogenesis, centrosome duplication, and genomic stability (UniProt P06748). In clinical oncology, NPM1 mRNA is a critical therapeutic target and a primary biomarker for acute myeloid leukemia (AML), where mutations in the gene occur in approximately 30% of adult cases (Falini et al., 2005). These mutations lead to the production of a protein that aberrantly localizes to the cytoplasm, driving the leukemic state. Therapeutic strategies targeting the mRNA, such as antisense oligonucleotides (ASOs) and small interfering RNA (siRNA), are designed to selectively degrade the transcript and prevent the translation of the oncogenic protein (Balusu et al., 2011). Furthermore, the quantification of NPM1 mRNA levels in the blood or bone marrow is the gold standard for monitoring minimal residual disease (MRD), allowing for the early detection of relapse and assessment of treatment efficacy (Ivey et al., 2016). As a therapeutic target, it offers the potential for high specificity, although challenges remain regarding the delivery of RNA-based drugs to the hematopoietic niche.
