Activity Dependent Protein Degradation Is Critical for the Formation and Stability of Fear Memory in the Amygdala
(PLOS, 2011-09)Protein degradation through the ubiquitin-proteasome system [UPS] plays a critical role in some forms of synaptic plasticity. However, its role in memory formation in the amygdala, a site critical for the formation of fear ... -
Acute heat stress activated inflammatory signaling in porcine oxidative skeletal muscle
(2017-08)Despite well-studied clinical manifestations, intracellular mechanisms of prolonged hyperthermic injury remain unclear, especially in skeletal muscle. Given muscle's large potential to impact systemic inflammation and ... -
Additional Molecular Evidence that The Royal Palm is Probably a Turkey Breed
(2019-07-09)In earlier investigations, we reported the uniqueness of Royal Palm from other commonly raise heritage turkeys. Here, we provide evidence from screening using primers specific for the Melanocortin 1 (MC1R) Receptor gene ... -
Advancing livestock genomics education and research in developing countries using strategies from the Virginia Tech PREP and IMSD training programs
(2019-07-11)Our unique and impactful research and education program plan includes distinct activities that target three overlapping phases of each trainee’s tenure, which we define as the “moving in,” “moving through,” and “moving ... -
Ag Commodities - VCE Showcasing Scholarship Poster
(2017-02-22)Youth are our future. Agriculture is our lifeline. Extension merges these two vital topics together through the 4-H Agriculture Commodities Tour, bringing awareness of the necessity for both to meet on an intimate real-life, ... -
Allelic variation in rice Fertilization Independent Endosperm 1 contributes to grain width under high night temperature stress
(2020-10)A higher minimum (night-time) temperature is considered a greater limiting factor for reduced rice yield than a similar increase in maximum (daytime) temperature. While the physiological impact of high night temperature ... -
Altered phosphorylation, electrophysiology, and behavior on attenuation of PDE4B action in hippocampus
(BMC, 2017)Background: PDE4 cyclic nucleotide phosphodiesterases regulate 3′, 5′ cAMP abundance in the CNS and thereby regulate PKA activity and phosphorylation of CREB, which has been implicated in learning and memory, depression ... -
AMP-Activated Protein Kinase Mediates the Effect of Leptin on Avian Autophagy in a Tissue-Specific Manner
(Frontiers, 2018-05-15)Autophagy, a highly conserved intracellular self-digestion process, plays an integral role in maintaining cellular homeostasis. Although emerging evidence indicate that the endocrine system regulates autophagy in mammals, ... -
An assessment of genomic connectedness measures in Nellore cattle
(2020-11)An important criterion to consider in genetic evaluations is the extent of genetic connectedness across management units (MU), especially if they differ in their genetic mean. Reliable comparisons of genetic values across ... -
Association between FAMACHA scores and fecal egg counts in Katahdin lambs
(2017-03)The FAMACHA system was introduced to the U.S. just over 10 yr ago to allow selective deworming of lambs with anemia associated with Haemonchus contortus and retard the development of anthelmintic resistance. The FAMACHA ... -
Association of Polymorphisms in the Period3 (turPer3) Gene with Growth and Reproductive Traits in Turkeys (Meleagris gallopavo)
Background and objective: Biological clock controls behavioral, physiological and biochemical circadian rhythms of animals. Circadian clock genes including period3 are involved in the circadian clock mechanism. The present ... -
Asymmetries in Chickens from Lines Selected and Relaxed for High or Low Antibody Titers to Sheep Red Blood Cells
(2015-03)Wattle length, width, and area were measured to classify bilateral asymmetries in four lines of chickens. The lines were the S26 generation of White Leghoms selected for high (HAS) or low (LAS) response to sheep red blood ... -
B-Lymphocytes Expressing an Ig Specificity Recognizing the Pancreatic beta-Cell Autoantigen Peripherin Are Potent Contributors to Type 1 Diabetes Development in NOD Mice
(Amer Diabetes Assoc, 2016-07-01)Although the autoimmune destruction of pancreatic b-cells underlying type 1 diabetes (T1D) development is ultimately mediated by T cells in NOD mice and also likely in humans, B cells play an additional key pathogenic role. ... -
Beef Cattle Breeds and Biological Types
(Virginia Cooperative Extension, 2005-09-01)There are more than 250 breeds of beef cattle. The breed, or combination of breeds, used in a defined breeding program have a significant impact on the efficiency and profitability of the beef enterprise. -
Beef heifer fertility: importance of management practices and technological advancements
(2020-10-01)The development of replacement heifers is at the core of cow-calf beef production systems. In 2020, the USDA, National Agricultural Statistics Service reported 5.771 million beef heifers, 500 pounds and over, are under ... -
Behavioral and Electrophysiological Characterization of Dyt1 Heterozygous Knockout Mice
(PLOS, 2015-03-23)DYT1 dystonia is an inherited movement disorder caused by mutations in DYT1 (TOR1A), which codes for torsinA. Most of the patients have a trinucleotide deletion (ΔGAG) corresponding to a glutamic acid in the C-terminal ... -
Biallelic modification of IL2RG leads to severe combined immunodeficiency in pigs
(2016-11-03)Background: Pigs with SCID can be a useful model in regenerative medicine, xenotransplantation, and cancer cell transplantation studies. Utilizing genome editing technologies such as CRISPR/Cas9 system allows us to generate ... -
Bidirectional Selection for Body Weight on Standing Genetic Variation in a Chicken Model
(Genetics Society of America, 2019-04)Experimental populations of model organisms provide valuable opportunities to unravel the genomic impact of selection in a controlled system. The Virginia body weight chicken lines represent a unique resource to investigate ...
