As shown in Table 2, obesity was associated with higher levels of IL-12 (P40), MIP-1a in myocardial tissue, while KD alone was associated with higher levels of G-CSF, IL-9, MCP-1, MIP-1a, MIP-1b, RANTES, and TNF-α in myocardial tissue. The gene discussed is CCL2; the disease is obesity due to melanocortin 4 receptor deficiency.
