C1QTNF7 and hyperinsulinism: However, during the OGTT, circulating CTRP7 concentration gradually decreased from 134.6 ± 21.2 to 105.9 ± 17.6 μg/L at 30 min, then to 105.5 ± 14.1 μg/L at 60 min, and finally to 99.9 ± 13.9 μg/L at 120 min (Figure 4(a)), indicating that hyperglycemia and/or hyperinsulinemia inhibited the secretion and release of CTRP7.
