Urinary bladder enlargement across nine rodent models of diabetes: correlations with glucose and insulin levels
2021
AbstractThe urinary bladder is markedly enlarged in the type 1 diabetes mellitus model of streptozotocin (STZ)-injected rats, but much less data exist for models of type 2 diabetes (T2DM). Diabetic polyuria has been proposed to explain bladder enlargement. We have collected data on bladder weight and blood glucose from 16 studies representing 9 distinct rodent diabetes (7 T2DM) and obesity models; some included arms with diets and/or pharmacological treatments. Data were analyzed for bladder enlargement and for correlations between bladder weight on the one and glucose levels on the other hand. Our data confirm major bladder enlargements in STZ rats, minor if any enlargement in fructose-fed…
Urinary Bladder Weight and Function in a Rat Model of Mild Hyperglycemia and Its Treatment With Dapagliflozin
2019
Hypertrophy and dysfunction of the urinary bladder are consistently observed in animal models of type 1 and less consistently in those of type 2 diabetes. We have tested the effects of mild hyperglycemia (n = 10 per group) in a randomized, blinded study and, in a blinded pilot study, of type 2 diabetes (n = 6 per group) and its treatment with dapagliflozin (1 mg/kg per day) on weight, contraction, and relaxation of the rat bladder. Based on a combination of high-fat diet and a low dose of streptozotocin, animals in the main study reached a mean peak blood glucose level of about 300 mg/dl, which declined to 205 mg/dl at study end. This was associated with a small, if any, increase in bladder…

Validation of Fenoterol to Study β<sub>2</sub>-Adrenoceptor Function in the Rat Urinary Bladder
2021
Fenoterol is a β<sub>2</sub>-adrenoceptor (AR)-selective agonist that is commonly used to investigate relaxation responses mediated by β<sub>2</sub>-AR in smooth muscle preparations. Some data have questioned this because fenoterol had low potency in the rat urinary bladder when a muscarinic agonist was used as a pre-contraction agent and because some investigators proposed that fenoterol may act in part via β<sub>3</sub>-AR. We designed the present study to investigate whether fenoterol is a proper pharmacological tool to study β<sub>2</sub>-AR-mediated relaxation responses in the rat urinary bladder. Firstly, we have compared the effect of p…
