Increased rate of fatty acid uptake and plasmalemmal fatty acid transporters in obese Zucker rats
Download2001
Arumugam, Yoga, Luiken, Joost J. F. P., Dyck, David J., Bonen, Arend, Tandon, Narendra N., Pelsers, Maurice M. L., Bell, Rhonda C., Turcotte, Lorraine P., Glatz, Jan F. C.
Giant vesicles were used to study the rates of uptake of long-chain fatty acids by heart, skeletal muscle, and adipose tissue of obese and lean Zucker rats. With obesity there was an increase in vesicular fatty acid uptake of 1.8-fold in heart, muscle and adipose tissue. In some tissues only...

Folate, vitamin B12, and vitamin B6 status of a group of high socioeconomic status women in the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort

Fayyaz, Faiqa, Wang, Flora, Jacobs, René L., O'Connor, Deborah L., Bell, Rhonda C., Field, Catherine J.
Folic acid supplementation and food fortification policies have improved folate status in North American women of child bearing age. Recent studies have reported the possible inadequacy of vitamin B12 and B6 in the etiology of neural tube defects in folate-fortified populations. The aims of this...

Wan, Zhongxiao, MacDonald, Tara, Wright, David C., Holloway, Graham P., Chan, Catherine B., Perry, Christopher G.
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...

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...

Assessment of pre-pregnancy dietary intake with a food frequency questionnaire in Alberta women
Download2015
Berglund, Casey, Ramage, Stephanie M., Harber, Vicki, McCargar, Linda J., Bell, Rhonda C.
Purpose: Pre-pregnancy is an under-examined and potentially important time to optimize dietary intake to support fetal growth and development as well as maternal health. The purpose of the study was to determine the extent to which dietary intake reported by non-pregnant women is similar to...
