Theses and Dissertations (ETD)

Ex vivo gene transfer can improve the outcome of islet transplantation for treating Type I diabetes. Earlier we have shown co‑expression of human vascular endothelial growth factor (hVEGF) and human interleukin‑1 receptor antagonist (hI‑1Ra) after transfection of plasmid DNA encoding these two genes. Due to poor transfection efficiency of plasmid DNA and the better known islet transduction efficiency of adenoviral (Adv) vectors, in this study, we constructed Adv‑hVEGF‑hIL‑1Ra by cloning hVEGF and hIL‑1Ra coding sequences and polyA signal under separate cytomegalovirus (CMV) promoters in Adenoquick plasmid (Ad 13.1). There was dose and time dependent expression of these genes after transduction …

We investigated the contractile roles of M2 and M3 muscarinic receptors in urinary bladder from streptozotocin-treated mice. Wild-type and M2 muscarinic receptor knockout (M2 KO) mice were given a single injection of vehicle or streptozotocin (125 mg kg−1) 2–24 weeks prior to bladder assays. The effect of forskolin on contractions elicited to the muscarinic agonist, oxotremorine-M, was measured in isolated urinary bladder (intact or denuded of urothelium). Denuded urinary bladder from vehicle-treated wild-type and M2 KO mice exhibited similar contractile responses to oxotremorine-M, when contraction was normalized relative to that elicited by KCl (50 mM). Eight to 9 weeks after …
