However, feed intake (Table 1), number (Figure 2) and size (Figure 3, data not shown) of small intestinal tumors, GTT results (Figure 5), nonfasted blood glucose levels (data not shown), insulin (Figures 6(a) and 6(b)) and TNFα (Figure 6(d)) levels were not significantly different between the ob/wt and wt/wt mice. This evidence concerns the gene TNF and small intestine neoplasm.
