Deficiency of Antioxidative Paraoxonase 2 (Pon2) Leads to Increased Number of Phenotypic LT-HSCs and Disturbed Erythropoiesis

Figure 1

Pon2 mRNA expression level in WT mice changes upon aging. LT-HSCs, ST-HSCs, MPPs, CMPs, GMPs, MEPs, and liver cells were obtained from young (2-3 months) and aged (>9 months) WT mice. Pon2, Gapdh, and Actb mRNA expression was analyzed by qRT-PCR. Pon2 mRNA expression was normalized to Gapdh and Actb mRNA expression. The relative Pon2 mRNA expression in LT-HSCs from young WT mice was set to 1. Shown are the of experiments using 2-6 mice per group (, , ns: not significant vs. WT cells; 2-way ANOVA with Bonferroni’s multiple comparisons test).
