Glucosamine-induced insulin resistance in ovariectomized rats is relevant to decreasing the expression of glucose transport protein subtype 4 in the skeletal muscle and in increasing the size of pancreatic islets.

Glucosamine (GlcN) is a popular nutritional supplement used to treat osteoarthritis in postmenopausal women. Postmenopausal women are at higher risk of type 2 diabetes mellitus and metabolic syndrome because of ovarian hormone deficiency. We used ovariectomized (OVX) rats as the model to investigate whether GlcN would induce insulin resistance (IR) in OVX rats and the underlying mechanisms. ⋯ The results demonstrate that female rats do not develop IR upon GlcN treatment except after ovariectomy. Those who take GlcN after menopause or bilateral oophorectomy should watch their blood glucose level closely, especially after meals.
