Transfer of adipocyte CD73 and TNAP (Figure 6a,b), as well as erythrocyte AChE and CD59 (Figure 6c–f), were highest for obese ZDF rats exhibiting elevated fasting blood glucose (hyperglyemia) and elevated fasting plasma insulin (hyperinsulinemia) levels, followed by obese ZF rats with normal fasting blood glucose (normoglycemia) and hyperinsulinemia and obese normoglycemic Wistar rats with mild hyperinsulinemia. Here, NT5E is linked to hyperinsulinism.
