Abstract

Insights

Proviral integration of Moloney murine leukemia virus 1 (PIM1) is elevated in acute myeloid leukemia (AML) patients. High PIM1 expression correlates with adverse characteristics and poorer prognosis, identifying it as a potential biomarker.

Area of Science:

  • Oncology
  • Molecular Biology
  • Hematology

Background:

  • Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy.
  • Proviral integration of Moloney murine leukemia virus 1 (PIM1) is a proto-oncogene implicated in cell proliferation and survival.

Purpose of the Study:

  • To evaluate PIM1 expression levels in AML patients.
  • To investigate the clinical significance and prognostic value of PIM1 in AML.

Main Methods:

  • Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to measure PIM1 expression in 80 AML patients and 20 healthy controls.
  • Clinicopathological data and survival outcomes were analyzed in relation to PIM1 expression levels.
  • Kaplan-Meier and Cox regression analyses assessed the prognostic impact of PIM1.

Main Results:

  • PIM1 expression was significantly higher in AML patients than in controls (p < 0.0001).
  • High PIM1 expression was associated with specific FAB classifications, treatment response, and poorer prognosis (p < 0.05).
  • Overall survival was markedly shorter in patients with high PIM1 expression, identifying it as an independent risk factor for poor prognosis.

Conclusions:

  • PIM1 is overexpressed in AML and linked to adverse clinicopathological features and outcomes.
  • PIM1 demonstrates potential as a prognostic biomarker for AML.
  • PIM1 may represent a viable therapeutic target for AML treatment.
