ERBB2 and breast cancer: Unlike VLDLs and LDLs the plasma HDLs were generally poorly affected by the presence of the HER2-positive BC (Figure 3d), except for the content of free Chol (p = 6.5 × 10−5; q = 0.001), Chol (p = 0.002; q = 0.013) and Apo A2 (p = 0.001; q = 0.008) in HDL-4 that resulted significantly decreased in BC patients (Table S2).
