- Abstract/Summary: Avenanthramides are a group of N-cinnamolyanthranilic acids comprising anthranilic acid and cinnamic acid connected by an amide linkage with health-promoting properties mainly found in oat (Avena sativa L.). In this research, avenanthramide A, B and C (Avn-A, B and C), the three most abundant avenanthramides (Avns) in oat, were identified and quantified from oat varieties. Subsequently, in vitro antioxidant activities of oat extracts and Avn-A, B and C were evaluated, and Avn-C had the highest in vitro antioxidant activity among the three avenanthramides. To investigate the cytoprotective activity of Avns, normal human skin fibroblasts (2DD) were treated with Avn C followed by exposure to extracellular stress and its ability to reduce cellular damage was determined. Pre-treatment of cells with Avn-C reduced hydrogen peroxide (H2O2)-induced oxidative stress significantly as demonstrated by decreased intracellular free radical levels and antioxidant gene transcripts. Avn-C pre-treatment also resulted in decreased levels of gene transcripts encoding pro-inflammatory cytokines in response to H2O2 or tumor necrosis factor α (TNF-α) stimulation. This reduction in cytokine gene transcription occurred concomitantly with reduced phosphorylated nuclear factor-κB (NF-κB) p65, indicating reduced pro-inflammatory response. To better understand the mechanisms of actions, the impact of Avn-C on cellular signaling pathways was investigated on Avn C-treated 2DD cells without exposure to stress. Avn-C was found to induce heme oxygenase-1 (HO-1) expression through increased DNA-Nrf2 binding activity. Also, it reduced basal levels of pro-inflammatory cytokines through decreased DNA-NF-κB binding activity. Moreover, anti-proliferative effect of Avn C on 2DD cells was observed via mechanisms independent of autophagy activation. Collectively, our findings suggest that Avn-C protects normal human skin fibroblasts against oxidative stress and inflammatory response through Nrf2/HO-1 activation and NF-κB inhibition.

- Abstract/Summary: Over the four years (2014-2017) that field surveys were conducted in commercial oat fields to evaluate the prevalence of oat leaf blotch pathogens P. avenae was the most often identified, being present in 59% of the 160 fields surveyed. Cochliobolus sativus was present in 23% of surveyed fields while S. avenae was only identified in 3% of fields. The ranking prevalence of these pathogens was consistent across all four years and differs from prior surveys conducted where S. avenae was observed in all years and with greater prevalence than C. sativus in most years (2011-2013).
Research Topic: Nutrition/Product Creation
- Project Status: Completed
- Principal Investigators: Dr. Lingyun Chen, University of Alberta
- Project Dates: January, 2016 - December, 2017
- Abstract/Summary: Oats is the logical choice to development of a non-dairy creamer. Oats have functional/nutrition proteins, they have high levels of beta glucan, and they can be utilized fairly well in beverage applications. Compared to faba bean, canola, and an oat/faba bean protein blend, oat proteins were shown to be the most suitable choice to replace dairy and soy proteins within a coffee creamer.
Research Topic: Insect/Disease/Weeds
- Project Status: Completed
- Abstract/Summary: The study takes a look at the occurrence of toxigenic Fusarium and Penicillium fungi and their associated mycotoxins, and an investigation of the fate of Fusarium and Penicillium species and their associated mycotoxins during processing of oats.

- Project Dates: April 2019 - March 2023
- Abstract/Summary: To build on Western Canada’s position as a supplier of premium quality oats to the current US markets, and developing markets like Mexico and China, requires developing varieties with a strong disease resistance package (of which crown rust resistance is a critical component). This will provide value to growers, through improved yield and reduced input costs (i.e. reduced fungicide use) which will help oat remain a viable crop within a grower’s rotation, and to millers/food processors, through higher selectability (i.e. good plumpness and test weight).
Research Topic: Variety/Trials
