Acute insulin stimulation significantly increased the fractional activity FV0.1 of GS in control cultures in the range of 0.1 pmol / l to 0.1 nmol / l (P < 0.05) and in diabetic cultures in the range of 0.1 pmol / l to 1.0 nmol / l (P < 0.05), whereas higher insulin concentrations diminished the effect of acute insulin stimulation in a dose - dependent pattern.

It spurred the fastest growth of fibroblast cells, with 17 per cent more cells formed after six days as in a control culture.
After one year, growth rates relative to the control cultures had increased slightly, but later hardly any increase could be detected — which is a contrast to many other evolution experiments.
Furthermore, in control cultures that were untransduced or treated with R5 - ZFNs, viral titers exponentially increased until extensive cell death began approximately 8 — 10 days post infection.
As seen in ccr5 wild type CD4 + T cells, exponential cell growth was preserved in cultures treated with X4 - ZFNs compared to control cultures that were untransduced or treated with R5 - ZFNs (Figure 5A).
Acute insulin stimulation significantly increased GS activity at 0.1 mmol / l in both diabetic (P < 0.0001) and control (P < 0.0001) cultures; however, GS activity at 10 mmol / l was unaffected by acute insulin stimulation in both culture types (P > 0.55 in diabetic and control cultures).
In contrast, increasing glycogen content seems to inhibit GS activity in control cultures.
Fig. 3 shows dose - response curves for the impact of insulin on the fractional velocity FV0.1 of GS in type 2 diabetic (Fig. 3B) and control cultures (Fig. 3A).
To get further insight into the differences between diabetic and control cultures, we compared the absolute differences between the basal and the insulin - stimulated state (ΔA0.5)(Fig. 4C).
However, we found that the G6P concentrations in type 2 diabetic culture and control cultures were comparable, indicating that type 2 diabetic cultures at euglycemia not are compensating for reduced FV0.1 by increasing the G6P concentration.

C: The glycogen content in the basal state in control cultures (□) and in diabetic cultures -LRB-[cjs2113]-RRB- at the indicated insulin concentrations.

We evaluated the capacity for glucose uptake in control and diabetic cultures precultured under three different insulin concentrations and found that when precultured with 1 pmol / l and 1 nmol / l insulin, the basal glucose uptake was reduced by 30 % (P < 0.05) in diabetic cultures compared with control cultures (Fig. 5).
ΔFV0.1 was significantly lower for 0.1 — 1 pmol / l insulin in the diabetic cultures compared with control cultures (P < 0.05), but these differences disappear with increasing insulin concentration as ΔFV0.1 significantly increases in diabetic cultures.
