[Relationship between Polymorphism in ALOX5, ALOX5AP and Susceptibility to Myeloid Leukemia]

Area of Science:

• Genetics
• Oncology
• Molecular Biology

Background:

• Myeloid leukemia (ML) is a significant health concern.
• Genetic factors, including single nucleotide polymorphisms (SNPs), play a role in ML development.
• The arachidonate 5-lipoxygenase (ALOX5) and 5-lipoxygenase activating protein (ALOX5AP) genes are implicated in inflammatory pathways relevant to cancer.

Purpose of the Study:

• To investigate the association between specific SNPs in the ALOX5 and ALOX5AP genes and the risk of adult myeloid leukemia.
• To identify genetic markers that may predict susceptibility to ML.

Main Methods:

• A case-control study was conducted with 150 ML patients and 134 healthy controls.
• Genomic DNA was extracted, and Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) combined with direct sequencing was used.
• Polymorphisms in ALOX5 (rs2029253, rs2228064, rs2228065) and ALOX5AP (rs10507391, rs4769874) were analyzed.

Main Results:

• The ALOX5 rs2029253 site showed a significant correlation with ML risk; genotype AA and A allele were linked to increased risk (OR=2.26, P<0.05; OR=1.44, P<0.05).
• Genotype AG and G allele of ALOX5 rs2029253 were associated with reduced ML susceptibility (OR=0.46, P<0.01; OR=0.69, P<0.05).
• The ALOX5AP rs10507391 genotype AA correlated with decreased ML risk (OR=0.13, P<0.05).
• No significant correlation was found for ALOX5 rs2228064, rs2228065, and ALOX5AP rs4769874 polymorphisms with ML risk.

Conclusions:

• Specific genotypes and alleles of ALOX5 (rs2029253) and ALOX5AP (rs10507391) are associated with susceptibility to myeloid leukemia.
• These findings suggest potential genetic biomarkers for ML risk assessment.
