Expression of PPARα modifies fatty acid effects on insulin secretion in uncoupling protein-2 knockout mice
Download2007
Fatehi-Hassanabad, Zahra, Chan, Catherine B.
Aims/hypothesis In uncoupling protein-2 (UCP2) knockout (KO) mice, protection of beta cells from fatty acid exposure is dependent upon transcriptional events mediated by peroxisome proliferator-activated receptor-α (PPARα). Methods PPARα expression was reduced in isolated islets from UCP2KO and...

Acculturation, dietary acceptability and diabetes management among Chinese in North America
Download2013
Zhang, Anran, Chan, Catherine B., Deng, Feiyue
Immigrants to a new country face many challenges when diagnosed with type 2 diabetes, a chronic disease with a complex treatment involving both medical and behavioral interventions. These challenges will depend upon the extent to which the patient has adapted to the new country’s social and...

Background Adipose tissue mitochondria have been implicated as key mediators of systemic metabolism. We have shown that IL-6 activates AMPK, a mediator of mitochondrial biogenesis, in adipose tissue; however, IL-6−/− mice fed a high fat diet have been reported to develop insulin resistance. These...

Chronic exposure to elevated free fatty acids (lipotoxicity) induces uncoupling protein (UCP2) in the pancreatic β-cell, and therefore a causal link between UCP2 and β-cell defects associated with obesity may exist. Recently, we showed that lipid treatment in vivo and in vitro in UCP2(–/–)...

Glucose-regulated glucagon secretion requires insulin receptor expression in pancreatic α-cells
Download2005
Chan, Catherine B., Wheeler, Michael B., Asghar, Zeenat, Diao, Jingyu
The insulin receptor (IR) and its signaling appear to be essential for insulin secretion from pancreatic β-cells. However, much less is known about the role of the IR in α-cells. To assess the role of the IR in glucagon and insulin secretion, we engineered adeno-viruses for high efficiency small...

Assessing the effects of weather conditions on physical activity participation using objective measures
Download2009
Chan, Catherine B., Ryan, Daniel A.
Habitual physical activity is an important determinant of health, yet many people are considered to be inactive. Identification of the obstacles to greater participation is necessary for the development of strategies to overcome those obstacles. The weather has been identified as a perceived...

Isoferulic acid, a new anti-glycation agent, inhibits fructose- and glucose-mediated protein glycation in vitro
Download2013
Meeprom, Aramsri, Adisakwattana, Sirichai, Sompong, Weerachat, Chan, Catherine B.
The inhibitory activity of isoferulic acid (IFA) on fructose- and glucose-mediated protein glycation and oxidation of bovine serum albumin (BSA) was investigated. Our data showed that IFA (1.25–5 mM) inhibited the formation of fluorescent advanced glycation end products (AGEs) and non-fluorescent...

A member of the neuronal Ca2+-sensor protein family visinin-like-protein-1 (vilip-1) is expressed in pancreatic β-cells and regulates insulin secretion and biosynthesis
Download2006
Gaisano, Herbert Y., Braunewell, Karl-Heinz, Dai, Feihan F., Chan, Catherine B., Wang, Qinghua, Kang, Youhou, Wheeler, Michael B., Zhang, Yi
Visinin-like protein-1 (VILIP-1) is a member of the neuronal Ca2+ sensor protein family that modulates Ca2+-dependent cell signaling events. VILIP-1, which is expressed primarily in the brain, increases cAMP formation in neural cells by modulating adenylyl cyclase, but its functional role in...

Sompong, Weerachat, Suantawee, Tanyawan, Thilavech, Thavaree, Adisakwattana, Sirichai, Meeprom, Aramsri, Chan, Catherine B.
Background Isoferulic acid (IFA), a naturally occurring cinnamic acid derivative, is a main active ingredient of the rhizoma of Cimicifuga dahurica. It has been shown various pharmacological activities. The aim of the study was to investigate the effect of IFA against MG-induced protein glycation...

Collective knowledge: Using a consensus conference approach to develop recommendations for physical activity and nutrition programs for persons with type 2 diabetes
Download2012
Bell, Rhonda C., Walker, Jessica, Chan, Catherine B., Berry, Tanya R.
The purpose of this consensus conference was to have a lay panel of persons with type 2 diabetes (T2D) work in collaboration with an expert panel of diabetes professionals to develop strategies designed to improve dietary and physical activity adherence in persons with T2D. Lay panel participants...
