Hybrid Incompatibility Between Ldrosophila Virilis And D. Lummei Is Stronger In The Presence Of Transposable Elements, Dean M. Castillo, Leonie C. Moyle

Nebraska Cooperative Extension: Faculty and Staff Publications

Mismatches between parental genomes in selfish elements are frequently hypothesized to underlie hybrid dysfunction and drive speciation. However, because the genetic basis of most hybrid incompatibilities is unknown, testing the contribution of selfish elements to reproductive isolation is difficult. Here, we evaluated the role of transposable elements (TEs) in hybrid incompatibilities between Drosophila virilis and D. lummei by experimentally comparing hybrid incompatibility in a cross where active TEs are present in D. virilis (TE+) and absent in D. lummei, to a cross where these TEs are absent from both D. virilis (TE−) and D. lummei genotypes. Using genomic data, …

Isoform switching events with predicted functional consequences are common in many cancers, but characterization of switching events in esophageal adenocarcinoma (EAC) is lacking. Next-generation sequencing was used to detect levels of RNA transcripts and identify specific isoforms in treatment- naïve esophageal tissues ranging from premalignant Barrett’s esophagus (BE), BE with low- or high-grade dysplasia (BE.LGD, BE.HGD), and EAC. Samples were stratified by histopathology and TP53 mutation status, identifying significant isoform switching events with predicted functional consequences. Comparing BE.LGD with BE.HGD, a histopathology linked to cancer progression, isoform switching events were identified in 75 genes including KRAS, RNF128, and …

Digestibility Of Wheat Alpha-Amylase/Trypsin Inhibitors Using A Caricain Digestive Supplement, Angéla Juhász, Mitchell G. Nye-Wood, Gregory J. Tanner, Michelle L. Colgrave

Research outputs 2022 to 2026

Wheat is a major source of nutrition, though in susceptible people it can elicit inappropriate immune responses. Wheat allergy and non-celiac wheat sensitivity are caused by various wheat proteins, including alpha-amylase trypsin inhibitors (ATIs). These proteins, like the gluten proteins which can cause celiac disease, are incompletely digested in the stomach such that immunogenic epitopes reach the lower digestive system where they elicit the undesirable immune response. The only completely effective treatment for these immune reactions is to eliminate the food trigger from the diet, though inadvertent or accidental consumption can still cause debilitating symptoms in susceptible people. One approach …

Antibiotic resistance (AR) was increasingly recognized as a global and national problem. Prevention efforts are hampered by a lack of complete understanding of how transmission pathways contribute to human AR exposure. Many reports have indicated the presence of antibiotic-resistant bacteria in foods at retail, suggesting that food consumption, animal-derived foods in particular, can represent a significant source of AR exposure among consumers. The presence of Salmonella, including antibiotic-resistant Salmonella, has been frequently reported in terrestrial animal-derived foods such as meat, poultry, and dairy products, as well as in aquaculture products. Identification of the significant food sources that harbor …

Modeling The Impact And Accelerating The Process Of Transitioning To A Sustainable Healthy Diet Through Decision Support Systems, Prince Agyemang

Graduate Theses and Dissertations

Food production and consumption are essential in human existence, yet they are implicated in the high occurrences of preventable chronic diseases and environmental degradation. Although healthy food may not necessarily be sustainable and vice versa, there is an opportunity to make our food both healthy and sustainable. Attempts have been made to conceptualize how sustainable healthy food may be produced and consumed; however, available data suggest a rise in the prevalence of health-related and negative environmental consequences of our food supply. Thus, the transition from conceptual frameworks to implementing these concepts has not always been effective. This paper explores the …

Characterization Of Blueberry (Poly)Phenolics In Foods, Their Metabolites In Human Biological Samples And Anti-Inflammatory Effects Of Phytochemicals In Vitro, Laura Felgus-Lavefve

Graduate Theses and Dissertations

Blueberries’ popularity is in part supported by the health benefits associated with their consumption. Research has strongly focused on their polyphenol and anthocyanin concentration, one of the highest amongst commonly consumed foods. Polyphenols have demonstrated antioxidant effects in vitro, and consuming polyphenol-rich foods is associated with protective effects towards non-communicable diseases, but their direct bioactivity in the human body remains to be fully understood. It is estimated that about 90 to 95% of the initial polyphenol intake reaches the colon without being absorbed. Instead, phenolic compounds go through extensive biotransformations, consisting of catabolism into smaller compounds mostly carried out by …
