Investigation Of Alcohol-Induced Changes In Hepatic Histone Modifications Using Mass Spectrometry Based Proteomics, Crystina Leah Kriss Apr 2018

Investigation Of Alcohol-Induced Changes In Hepatic Histone Modifications Using Mass Spectrometry Based Proteomics, Crystina Leah Kriss

Graduate Theses and Dissertations

Alcohol liver disease (ALD) is a major health concern throughout the world. Currently, in the United States, 17 million people suffer from alcoholism, of which 1.4 million people are receiving treatment [1, 2]. The link between ethanol metabolism, reactive oxygen species (ROS) and liver injury in ALD has been well characterized over the last couple decades [3-10]. Ethanol metabolism relies on the availability of the cofactor NAD+ for the oxidation of ethanol into acetate, consequently causing alterations in redox potential. Redox dysfunction within the mitochondria can affect multiple pathways important in maintaining cellular homeostasis. Chapter 1 provides an introduction ...


Investigating The Interplay Of Physiological And Molecular Mechanisms Underpinning Programmable Aspects Of Heat Stress In Pigs, Jacob Seibert Jan 2018

Investigating The Interplay Of Physiological And Molecular Mechanisms Underpinning Programmable Aspects Of Heat Stress In Pigs, Jacob Seibert

Graduate Theses and Dissertations

Heat stress (HS) undermines production efficiency in all animal agriculture, culminating in major economic losses annually. The effects of HS in pigs is realized through depressed growth, altered body composition, and impaired reproductive performance. Pigs, unlike other mammals, do not possess functional sweat glands, making them rely on other mechanisms to thermoregulate during a heat challenge. Continual investigation of hyperthermia in pigs is crucial for developing new strategies and/or technologies that mitigate the effects of HS imposed on the pork industry. The studies conducted in this dissertation investigate the complex interplay of whole-animal physiology as well as cellular and ...


Epigenetic Interplay Between Histone H3k9me2 And Jil-1 Mediated Histone H3s10ph, Chao Wang Jan 2014

Epigenetic Interplay Between Histone H3k9me2 And Jil-1 Mediated Histone H3s10ph, Chao Wang

Graduate Theses and Dissertations

In Drosophila, JIL-1 Kinase specifically localizes to euchromatic interband regions of polytene chromosomes and is responsible for histone H3S10 phosphorylation at interphase. Previous genetic interaction assays have demonstrated that the JIL-1 protein can counterbalance the effect of the major heterochromatin components Su(var)3-7 on position-effect variegation (PEV). In this study, we show that the haplo-enhancer effect of JIL-1 has the ability to counterbalance the haplo-suppressor effect of two other major heterochromatin components, Su(var)3-9 and Su(var)2-5, on position-effect variegation, providing evidence that a finely tuned balance between the levels of JIL-1 and the major heterochromatin components ...
