Many biomarkers, including tumor necrosis factor, troponin, cystatin C, galectin 3, monocyte chemoattractant protein 1 (MCP-1), homocysteine, annexin A5, bone morphogenetic protein 4, and soluble receptor for advanced glycation end products (sRAGE), are currently under investigation for their associations with organ damage caused by hypertension [107,108,109,110,111,112,113]. The gene discussed is CCL2; the disease is hypertensive disorder.
