These studies examined the importance of phospholipase Cbeta (PLCbeta) in the calcium responses of pituitary cells using PLCbeta3 knockout mice. Pituitary tissue from wild-type mice contained PLCbeta1 and PLCbeta3 but not PLCbeta2 or PLCbeta4. Both Galphaq/11 and Gbetagamma can activate PLCbeta3, whereas only Galphaq/11 activates PLCss1 effectively. In(More)
Incretin hormones are secreted from the intestines in response to specific nutrients. They potentiate insulin secretion and have other beneficial effects in glucose homeostasis. We aimed to study the incretin effect in cats and to compare the effect of oral glucose, lipids, or amino acids on serum concentrations of insulin, total glucose-dependent(More)
The Doppler ultrasonic recording technique was used to measure systolic and diastolic blood pressures indirectly in 28 cats with naturally occurring renal failure, 39 cats with hyperthyroidism, and 33 clinically normal cats. The mean systolic and diastolic blood pressures in the normal cats were 118.4 +/- 10.6 mm Hg and 83.8 +/- 12.2 mm Hg, respectively. In(More)
The glucagon-like peptide-1 mimetic exenatide has a glucose-dependent insulinotropic effect, and it is effective in controlling blood glucose (BG) with minimal side effects in people with type 2 diabetes. Exenatide also delays gastric emptying, increases satiety, and improves β-cell function. We studied the effect of exenatide on insulin secretion during(More)
OBJECTIVE To evaluate clinical and laboratory findings, treatment, and clinical outcome in cats with blastomycosis. DESIGN Retrospective case series. ANIMALS 8 cats with naturally occurring blastomycosis. PROCEDURES Medical records of the University of Illinois Veterinary Teaching Hospital were searched for cases of blastomycosis in cats diagnosed via(More)
Hypercortisolism (HC) is a common disease in dogs. This article will review the laboratory tests that are available for diagnosis of HC and laboratory tests for differentiating between causes of HC. An emphasis will be made on the clinical process that leads to the decision to perform those tests and common misconceptions and issues that arise when(More)
We measured glomerular filtration rate (GFR) estimated by plasma disappearance of 99mTc-labeled diethylenetriaminepentaacetic acid, serum concentrations of thyroxine (T4), creatinine, and urea nitrogen, and urine specific gravity in 13 cats with naturally acquired hyperthyroidism before and 30 days after treatment by bilateral thyroidectomy, and in a group(More)
The role of the Ca(2+)-induced Ca(2+) release channel (ryanodine receptor) in MIN6 pancreatic beta-cells was investigated. An endoplasmic reticulum (ER)-targeted "cameleon" was used to report lumenal free Ca(2+). Depolarization of MIN6 cells with KCl led to release of Ca(2+) from the ER. This ER Ca(2+) release was mimicked by treatment with the ryanodine(More)
BACKGROUND Antimicrobial peptides (AMPs) are small immunomodulatory peptides produced by epithelial and immune cells. β-Defensins (BDs) and cathelicidins (Caths) are the most studied AMPs. Recently, increased cutaneous expression of AMPs was reported in atopic humans and in beagles with experimentally induced atopy. HYPOTHESIS/OBJECTIVES Our goal was to(More)
The mechanisms contributing to BW gain following ovariohysterectomy in domestic cats are poorly understood. Moreover, the effects of food restriction to maintain BW following spaying have been poorly studied. Thus, our primary objective was to determine the effects of spaying and food restriction to maintain BW on adipose and skeletal muscle mRNA abundance(More)
