Value of serum soluble lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and LOX-1 mRNA in peripheral mononuclear cells in early diagnosis of acute coronary syndrome / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of serum soluble lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) levels and LOX-1 mRNA expression in peripheral blood mononuclear cells in early diagnosis of acute coronary syndrome (ACS).</p><p><b>METHODS</b>Enzyme-linked immunosorbent assay was used to detect the levels of plasma ox-LDL and LOX-1 in 95 patients with ACS, 60 with stable angina pectoris (SAP) and 40 normal control subjects. The expression of LOX-1 mRNA in peripheral blood mononuclear cells was detected by RT-PCR in the 3 groups.</p><p><b>RESULTS</b>The levels of ox-LDL, LOX-1 and LOX-1 mRNA in the peripheral blood mononuclear cells were significantly higher in ACS patients than in SAP patients and normal control subjects (P<0.05). In ACS group, the level of plasma ox-LDL was significantly correlated to serum LOX-1 and LOX-1 mRNA expression in peripheral mononuclear cells.</p><p><b>CONCLUSION</b>The level of plasma soluble LOX-1 and LOX-1 mRNA in peripheral mononuclear cells are significantly increased in ACS, and when combined, they provide a useful means for detecting ACS in the prophase.</p>
