| Research Abstract |
Type I and II diabetes is a common disease and a major public health problem. To identify the susceptibility gene to diabetes we performed genome-wide quantitative trait loci (QTL) analysis, using db mice in C57BL6/ksj background or NOD-RGP-IL-10 Tg in NOD background. db mouse is an animal model of type II diabetes in human exhibiting hyperglycemia, hyperinsulinemia, insulin resistance, and obesity. F2 intercross between db mice and non-diabetic C3H strain demonstrated a wide variety of diabetes related, including body weight, plasma glucose concentration, plasma insulin concentration, and glucose tolerance. We have identified several QTLs associated with body weight and glucose tolerance. NOD-RGP-IL-10 Tg enhance autoimmune diabetes, but none of the resulting F1 mice outbred to C57BL/6 mice show diabetes. N2 backcross between NOD-RGP-IL-10 Tg and C57BL/6 mice demonstrated 15% incidence of diabetes. Similar to db mice, we are performing genome-wide quantitative trait loci (QTL) analysis for N2 generation.
