Abstract EN
Insulin resistance and loss of β-cell mass cause Type 2 diabetes (T2D).
The objective of this study was to generate a nongenetic mouse model of T2D.
Ninety-six 6-month-old C57BL/6N males were assigned to 1 of 12 groups including (1) low-fat diet (LFD; low-fat control; LFC), (2) LFD with 1 i.p.
40 mg/kg BW streptozotocin (STZ) injection, (3), (4), (5), (6) LFD with 2, 3, 4, or 5 STZ injections on consecutive days, respectively, (7) high-fat diet (HFD), (8) HFD with 1 STZ injection, (9), (10), (11), (12) HFD with 2, 3, 4, or 5 STZ injections on consecutive days, respectively.
After 4 weeks, serum insulin levels were reduced in HFD mice administered at least 2 STZ injections as compared with HFC.
Glucose tolerance was impaired in mice that consumed HFD and received 2, 3, or 4 injections of STZ.
Insulin sensitivity in HFD mice was lower than that of LFD mice, regardless of STZ treatment.
Islet mass was not affected by diet but was reduced by 50% in mice that received 3 STZ injections.
The combination of HFD and three 40 mg/kg STZ injections induced a model with metabolic characteristics of T2D, including peripheral insulin resistance and reduced β-cell mass.
