To explore whether the observed differences in vitamin C levels may support dysfunctions of physiological uptakes mechanisms, a quantitative assessment of SCL23A2, SLC2A1, and SLC2A3 transcripts was performed on PB-MNCs samples harvested at diagnosis from 22 AML cases and compared to those of 15 HDs. The gene discussed is SLC2A1; the disease is acute myeloid leukemia.
