Bovine respiratory disease: Effects on performance, immune response, cytokines and gene expression
(2009-07)Scope and Method of Study: The objective was to determine the effects of timing of an intratracheal Mannheimia haemolytica challenge relative to 72-hour exposure to bovine viral diarrhea type 1b (BVDV1b) persistently ... -
Cloning and expression of genes required for coronamic acid (2-ethyl-1-aminocyclopropane 1-carboxylic acid), an intermediate in the biosynthesis of the phytotoxin coronatine
(American Society for Microbiology, 1994-08)Coronamic acid (CMA; 2-ethyl-1-aminocyclopropane 1-carboxylic acid) is an intermediate in the biosynthesis of coronatine (COR), a chlorosis-inducing phytotoxin produced by Pseudomonas syringae pv. glycinea PG4180. Tn5 ... -
Constitutive expression of the cloned phenol hydroxylase gene(s) from Alcaligenes eutrophus JMP134 and concomitant trichloroethylene oxidation
(American Society for Microbiology, 1996-09)Given the demonstrated phenol-dependent trichloroethylene (TCE) degradation in Alcaligenes eutrophus JMP134 (A. R. Harker and Y. Kim, Appl. Environ. Microbiol. 56:1179-1181, 1990), this work represents a purposeful effort ... -
Effect of breed, tissue type, and time of weaning on fatty acid composition and gene expression in Angus and Charolais finishing steers
(2010-07)The effect of breed and tissue type on fatty acid composition and gene expression was evaluated using 33 steer calves. Calves were completely randomized to a 2 x 2 x 2 factorial treatment arrangement: sire breeds (Angus ... -
Effect of diet quality on dry matter intake, gene expression, greenhouse gas emissions, and production measures in mature beef cows
(2021-07)The purpose of this research was to examine the effect that diet quality had on dry matter intake, gene expression, greenhouse gas emissions, and production measures in gestating, mature Angus beef cows. Two experiments ... -
Effect of increased ruminal proprionate on the expression of hepatic gluconeogenic genes in cattle on a finishing ration
(Oklahoma State University, 2022-04-19)The objective of this experiment was to ascertain if supplementing calcium propionate (CaP) in varying amounts would result in the increased expression of genes related to glucose metabolism in the liver. The study utilized ... -
Effect of nutrition and management practices on marbling development by growing beef cattle
(2012-05)Three experiments were conducted to determine the effects of energy supplementation, rate of gain, and type of fermentation from different grazing programs on subsequent finishing performance, carcass characteristics, body ... -
Exploratory analysis of estrogen-mediated gene expression in central ghrelin signaling pathways
(Oklahoma State University Center for Health Sciences, 2022-02-18)Introduction & Objective: As of 2020, 67% of Americans are overweight or obese. Particularly concerning is the greater incidence of obesity in post-menopausal women. Previous studies have shown that estrogen decreases food ... -
Gene expression changes in muscle and liver tissue of growing beef calves with bovine respiratory disease
(2011-12)Scope and Method of Study: -
High throughput profiling of the cotton bollworm Helicoverpa armigera immunotranscriptome during the fungal and bacterial infections
(BioMed Central, 2015-04-18)Background: Innate immunity is essential in defending against invading pathogens in invertebrates. The cotton bollworm, Helicoverpa armigera (Hubner) is one of the most destructive lepidopteran pests, which causes enormous ... -
Identification and Characterization of Macrophage Migration Inhibitory Factor from the American Dog Tick, Dermacentor Variabilis (Say)
(Oklahoma State University, 2010-07-01)This study identified and characterized macrophage migration inhibitory factor (MIF) from the American dog tick, Dermacentor variabilis. The gene expression, protein level changes and function of MIF was studied using a ... -
Identification of the inducing agent of the 2,4-dichlorophenoxyacetic acid pathway encoded by plasmid pJP4
(American Society for Microbiology, 1997-01)The inducing agent of the 2,4-dichlorophenoxyacetic acid (2,4-D) pathway of Alcaligenes eutrophus JMP134 (pJP4) was determined through the analysis of promoterless lacZ transcriptional fusions with tfd structural genes. ... -
Molecular Divergence with Major Morphological Consequences: Development and Evolution of Organ Size and Shape
(2022-11)Understanding the causes of the morphological diversity among organisms is a topic of great interest to evolutionary developmental biologists. Although developmental biologists have had great success in identifying the ...
