Figure 1 The Role of Vitamin C in Homeostatic HSC/MPPs and Aberrant LSC Function Tet proteins catalyze the oxidation of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), a rate-limiting step toward DNA demethylation. In homeostasis, vitamin C regulates the balance between self-renewal, differentiation, and cell death of hematopoietic stem cells and multipotent progenitors (HSC/MPPs) by promoting Tet2 activity. In contrast, vitamin C depletion accelerates leukemogensis of Tet2-mutant leukemic stem cells (LSCs) and leads to increased aberrant self-renewal capacity.
