Mechanisms of insulin resistance - the effect of exercise
Due to a sedentary lifestyle, the prevalence of Type 2 Diabetes is increasing at alarming rates worldwide. Insulin resistance, defined as decreased ability of insulin to regulate glucose uptake in multiple organs including skeletal muscle is a key event in the development of Type 2 Diabetes. Acute exercise and training both ameliorate insulin resistance, while the underlying mechanisms are yet to be defined.
This ph.d.-thesis brings the obtained research results from 3 studies together with the current knowledge in the field of insulin signaling and insulin resistance.
The impact of an oversupply of energy, either as carbohydrates or fat, on both proximal and distal components in the insulin signaling cascade as well as the impact of exercise on insulin action in insulin sensitive and insulin resistant states are presented. Furthermore, activation of an alternative signaling pathway via leukemia inhibitory factor (LIF) was demonstrated, allowing for preservation of glucose uptake in insulin resistant white skeletal muscle.
