Altered microRNA expression in bovine subcutaneous and visceral adipose tissues from cattle under different diet
Download2012
Guan, Leluo, Romao, Josue M., McAllister, Tim, He, Maolong, Jin, Weiwu
Background MicroRNAs (miRNAs) are a class of molecular regulators found to participate in numerous biological processes, including adipogenesis in mammals. This study aimed to evaluate the differences of miRNA expression between bovine subcutaneous (backfat) and visceral fat depots (perirenal...

Comparative transcriptomic analysis of rectal tissue from beef steers revealed reduced host immunity in Escherichia coli O157:H7 super-shedders
Download2016-03-09
McAllister, Tim A., Wang, Ou, Plastow, Graham, Stanford, Kim, Liang, Guanxiang, Guan, Le L., Selinger, Brent
Super-shedder cattle are a major disseminator of E. coli O157:H7 into the environment, and the terminal rectum has been proposed as the primary E. coli O157:H7 colonization site. This study aimed to identify host factors that are associated with the super-shedding process by comparing...

Elucidation of molecular mechanisms of physiological variations between bovine subcutaneous and visceral fat depots under different nutritional regimes
Download2013
Jin, Weiwu, He, Maolong, Guan, Leluo, Romao, Josue M., McAllister, Tim
Adipose tissue plays a critical role in energy homeostasis and metabolism. There is sparse understanding of the molecular regulation at the protein level of bovine adipose tissues, especially within different fat depots under different nutritional regimes. The objective of this study was to...

Genome-wide whole blood microRNAome and transcriptome analyses revealed miRNA-mRNA regulated host response to foodborne pathogen Salmonella infection in swine
Download2015-07-31
Arantes, Adriano S., Tuggle, Christopher K., Guan, Le L., Bearson, Shawn M.D., Sun, Xu, Plastow, Graham S., Kommadath, Arun, Bao, Hua, Stothard, Paul, Liang, Guanxiang
To understand the role of miRNAs in regulating genes involved in host response to bacterial infection and shedding of foodborne pathogens, a systematic profiling of miRNAs and mRNAs from the whole blood of pigs upon Salmonella challenge was performed. A total of 62 miRNAs were differentially...

Kinome profiling of peripheral blood mononuclear cells collected prior to vaccination reveals biomarkers and potential mechanisms of vaccine unresponsiveness in pigs
Download2020-12-01
Lipsit, Sean W. L., Wilkinson, James, Scruten, Erin, Facciuolo, Antonio, Denomy, Connor, Griebel, Philip J., Kusalik, Anthony, Plastow, Graham, Napper, Scott
Inter-individual variance in host immune responses following vaccination can result in failure to develop protective immunity leaving individuals at risk for infection in addition to compromising herd immunity. While developing more efficacious vaccines is one strategy to mitigate this problem,...

Jin, Weiwu, He, Maolong, Guan, Leluo, Romao, Josue M., McAllister, Tim
Background MicroRNAs (miRNAs) are small non-coding RNAs found to regulate several biological processes including adipogenesis. Understanding adipose tissue regulation is critical for beef cattle as fat is an important determinant of beef quality and nutrient value. This study analyzed the...

Potential regulatory role of microRNAs in the development of bovine gastrointestinal tract during early life
Download2014
Liang, Guanxiang, Bao, Hua, Guan, Leluo, Griebel, Philip J., Stothard, Paul, McFadden, Thomas B., Malmuthuge, Nilusha
This study aimed to investigate the potential regulatory role of miRNAs in the development of gastrointestinal tract (GIT) during the early life of dairy calves. Rumen and small intestinal (mid-jejunum and ileum) tissue samples were collected from newborn (30 min after birth; n = 3), 7-day-old...

Roles of small RNAs in the effects of nutrition on apoptosis and spermatogenesis in the adult testis
Download2015
Malecki, Irek A., Martin, Graeme B., Cozens, Greg, Hawken, Penelope A.R., Liang, Guanxiang, Guan, Yongjuan, Vercoe, Philip E., Guan, Le Luo
We tested whether reductions in spermatozoal quality induced by under-nutrition are associated with increased germ cell apoptosis and disrupted spermatogenesis, and whether these effects are mediated by small RNAs. Groups of 8 male sheep were fed for a 10% increase or 10% decrease in body mass...

Systematic microRNAome profiling reveals the roles of microRNAs in milk protein metabolism and quality: Insights on low-quality forage utilization
Download2016
Wang, Diming, Sun, Huizeng, Liu, Jianxin, Guan, Le Luo, Wang, Bing, Liang, Guanxiang
In this study, we investigated the molecular regulatory mechanisms of milk protein production in dairy cows by studying the miRNAomes of five key metabolic tissues involved in protein synthesis and metabolism from dairy cows fed high- and low-quality diets. In total, 340, 338, 337, 330, and 328...
