Zika virus (ZIKV) causes no-to-mild symptoms or severe neurological disorders. To investigate the importance of viral and host genetic variations in determining ZIKV infection outcomes, we created three full-length infectious cDNA clones as bacterial artificial chromosomes for each of three spatiotemporally distinct and genetically divergent ZIKVs: MR-766 (Uganda, 1947), P6-740 (Malaysia, 1966), and PRVABC-59 (Puerto Rico, 2015). Using the three molecularly cloned ZIKVs, together with 13 ZIKV region-specific polyclonal antibodies covering nearly the entire viral protein-coding region, we made three conceptual advances: (i) We created a comprehensive genome-wide portrait of ZIKV gene products and their related species, with several previously …

Effects of Fescue Toxicosis on Whole Blood Gene Expression in Beef Cattle

The consumption of endophyte-infected tall fescue causes negative effects on the growth, reproduction, longevity, and overall health of beef cattle; this condition, termed fescue toxicosis by researchers and producers today, costs the United States over $1 billion in losses each year. To mitigate these production losses, it is important for producers to understand how fescue toxicosis affects gene expression and physiological pathways in beef cattle. This study examined the whole blood gene expression and affected pathways in beef cows grazing both endophyte-infected (toxic) tall fescue and (non-toxic) tall …

Evaluation Of Oocyte Developmental Competence And Potential Strategies To Improve Oocyte Quality, Min Yang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Assisted reproductive technologies (ARTs) have now been extensively used to promote reproductive efficiency as a fertility treatment not only in human medicine but also animal reproduction. ARTs serve as an important tool to advance the fundamental knowledge of reproductive processes. The quality of female’s eggs defines its ability to undergo maturation, fertilization, and development. This quality is determined by various factors and is crucial for the success of ARTs. Any alternations happening during the egg growth and maturation process can result in the decreased quality, which could have long-lasting effects on development. Improving the developmental efficiency of the egg is …

Gene Expression Levels In Some Candidate Genes For Mastitis Resistance, Milk Yield, And Milk Quality Of Goats Reared Under Different Feeding Systems, Akin Yakan, Hüseyi̇n Özkan, Aysel Eraslan Şakar, Necmetti̇n Ünal, Ceyhan Özbeyaz

Turkish Journal of Veterinary & Animal Sciences

This study aimed to identify the expression levels of some candidate genes for mastitis resistance (LTF and BRCA1), milk yield (POU1F1 and IGF-1), and milk quality (PPARγ and CSN2) in different feeding systems (pen- and pasture-based) used for Damascus goats. Milk samples were taken from all goats in both pen and pasture groups at 4 times, at the 1st, 3rd, 5th, and 7th months of the study. It was found that, compared to the pen group, the LTF and CSN2 genes in the pasture group had significant levels of upregulation in the 7th month of lactation (3.538- and 5.436-fold, respectively), …
