We then monitored the blood glucose and insulin levels in the three groups of animals at the end of the experiment period and found that the induction of diabetes in mice by STZ was associated with a significant elevation in the blood glucose level, a marked reduction in the circulating lymphocyte count and an evident decrease in the insulin levels compared to the control treatment (*P < 0.05, n = 10) (Table 2). The gene discussed is INS; the disease is diabetes mellitus.
