In both the HVs and patients with MS, the serum levels of AOPPs were positively correlated with the serum levels of total cholesterol (VLDL-C), free cholesterol (VLDL-FC), triglycerides (VLDL-TG), phospholipids (VLDL-PL), and apoB (VLDL-apoB) in the total VLDL (Figure 1A–E) as well as in VLDL subclasses 1–4 (Table S9). Here, APOB is linked to myeloid sarcoma.
