Expansion of ruminant-specific microRNAs shapes target gene expression divergence between ruminant and non-ruminant species
Download2013
Kommadath, A., Bao, H., Meng, Y., Plastow, G. S., Stothard, P., Sun, X., Arantes, A. S., Guan, L. L.
Background Understanding how species-specific microRNAs (miRNAs) contribute to species-specific phenotypes is a central topic in biology. This study aimed to elucidate the role of ruminant-specific miRNAs in shaping mRNA expression divergence between ruminant and non-ruminant species. ...

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...

SSHRC NFRF-E awarded 2019: With the requested funding, I will apply my expertise in T cells and metabolism to identify new potential metabolic drugs that can enhance immune function. We hypothesize that a Insulin-Resistance (IR)-related immune and metabolic defect contributes to increased risk of...

Impaired de novo choline synthesis explains why phosphatidylethanolamine N-methyltransferase-deficient mice are protected from diet-induced obesity
Download2010
Kuo, Ming-Shang, Dyck, Jason R. B., Sletten, Torunn, Proctor, Spencer D., Jacobs, René L., Lingrell, Susanne, Cao, Guoqing, Peake, David A., Kennedy, Brian P., Zhao, Yang, Vance, Dennis E., Koonen, Debby P. Y., Su, Brian
Phosphatidylcholine (PC) is synthesized from choline via the CDP-choline pathway. Liver cells can also synthesize PC via the sequential methylation of phosphatidylethanolamine, catalyzed by phosphatidylethanolamine N-methyltransferase (PEMT). The current study investigates whether or not hepatic...

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...

The calving transition is a challenging period for dairy cows characterized by negative energy balance, metabolic dysfunction, and inflammation, each of which may compromise milk production. Despite extensive research in this area, much is still unknown on how to best manage this period. The...

Investigation of an enhancer-based regulation of LILRB1 gene and the differential functions of LILRB1 variants in natural killer cells
DownloadFall 2020
Human cytomegalovirus (HCMV) causes severe disease in immunocompromised people such as transplant patients. NK cells are crucial in controlling HCMV whereas HCMV developed multiple strategies to evade NK cell surveillance. HCMV encodes a human MHC-I homolog called UL18 to target an inhibitory...

Limited mitochondrial permeabilization is an early manifestation of palmitate-induced lipotoxicity in pancreatic ß-cells
Download2008
Wheeler, Michael B., Chan, Catherine B., Dai, Feihan F., Koshkin, Vasilij, Robson-Doucette, Christine A.
Involvement of the mitochondrial permeability transition (MPT) pore in early stages of lipotoxic stress in the pancreatic β-cell lines MIN6 and INS-1 was the focus of this study. Both long term (indirect) and acute (direct) effects of fatty acid (FA) application on β-cell susceptibility to...

Long-term cardiovascular and metabolic effects of hypoxia-induced intrauterine growth restriction

Rueda-Clausen, Christian Federico
Cardiovascular and metabolic diseases are still the primary cause of death and disability in modern society. Although genetic factors play a fundamental role in the development of these chronic conditions, the remarkable variability in an individual’s susceptibility to develop these pathologies...
