Comparative Chemical Characterization Of Lunasin-Enriched Preparations And Modifications Of The Inflammasomes In Vitro, Samuel James Price May 2017

Comparative Chemical Characterization Of Lunasin-Enriched Preparations And Modifications Of The Inflammasomes In Vitro, Samuel James Price

Masters Theses

Soybean (Glycine max) is one of the most cultivated crops in the world providing the population with large amounts of protein and oil. In addition to its nutritional composition, soybean also contains biologically active compounds with potential health-promoting properties. The presence of these bioactives may be responsible for the lower incidence of chronic diseases in populations that consume a significant portion of soybeans in their diet. One group of soybeanderived bioactives are bioactive peptides and proteins including lunasin, Bowman-Birk inhibitor (BBI) and Kunitz-type trypsin inhibitor (KTI). The overall objective of this research was to develop a method of preparing lunasin-enriched ...


Effect Of Omega-3 Polyunsaturated Fatty Acid (N-3 Pufa) Supplementation To Lactating Sows On Growth And Indicators Of Stress In The Post-Weaned Pig, John M. Mcafee Dec 2016

Effect Of Omega-3 Polyunsaturated Fatty Acid (N-3 Pufa) Supplementation To Lactating Sows On Growth And Indicators Of Stress In The Post-Weaned Pig, John M. Mcafee

Masters Theses

The first experiment was designed to determine the concentration of protected fish oil product (PFO), as GromegaTM, to be added that would sufficiently decrease the polyunsaturated fatty acid (PUFA) ratio in the sows’ milk and colostrum. Of the 3 diets tested (0.25%, 0.5% and 1%) with a control (0% PFO), only the 1% PFO diet had an effect on the PUFA concentrations. The docosahexaenoic acid (DHA) concentration tended (P = 0.05) to be greater in the 1% PFO diet for both colostrum and milk samples. A second experiment was designed to examine the effects of feeding the ...


Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae Dec 2015

Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae

Doctoral Dissertations

Recent findings of brown adipocytes and brown-like or beige adipocytes, capable of dissipating energy as heat, in adult humans have promised new hope for obesity treatment and prevention. Understanding of the regulation of brown and beige adipocytes will provide novel strategies to reach the goal. Pattern recognition receptors (PRR) are responsible for inflammation in adipose tissue, which leads to adipose dysfunction and obesity associated chronic diseases. It has been shown that PRR activation induces inflammation, leading to insulin resistance in white adipocytes and white adipose tissue (WAT). However, the roles of PRR activation in brown adipocytes and brown adipose tissue ...


The Effects Of Leucine And Dairy Products On Adipose Tissue Inflammation: The Role Of Adipocyte Derived Microvesicles, Benjamin Jones Curry Aug 2014

The Effects Of Leucine And Dairy Products On Adipose Tissue Inflammation: The Role Of Adipocyte Derived Microvesicles, Benjamin Jones Curry

Doctoral Dissertations

Obesity is characterized by chronic oxidative and inflammatory stress, and adipose tissue is a significant source of inflammatory cytokines. Previous studies demonstrated that dairy products (rich in calcium and leucine) can alleviate obesity-associated inflammatory stress through suppression of 1, 25-dihydroxycholecalciferol (calcitriol) with calcium and the high leucine content in dairy. We have also shown leucine treatment increases anti-inflammatory adiponectin expression and decreases pro-inflammatory cytokines TNF-a [alpha], MCP-1, and IL-6 expression in adipocytes. Therefore, we sought to determine if these alterations in inflammatory cytokine production could have a functional effect on the inflammatory process, specifically monocyte – endothelial cell adhesion as this ...


Activation Of Nucleotide Binding Oligomerization Domain Containing Protein 1 In 3t3-L1 Adipocytes: Effects On Adipocyte Differentiation And Lipolysis, Jaanki Shamb Purohit Aug 2013

Activation Of Nucleotide Binding Oligomerization Domain Containing Protein 1 In 3t3-L1 Adipocytes: Effects On Adipocyte Differentiation And Lipolysis, Jaanki Shamb Purohit

Masters Theses

Obesity, defined as having excess adipose tissue, is associated with chronic inflammation. Adipose tissue is made up of many cell types, including preadipocytes and adipocytes. Both preadipocytes and adipocytes express pattern recognition receptors that play important roles in innate immunity. Two families of pattern recognition receptors that have been studied in adipose tissue are Toll-like receptors (TLRs) and NOD-like receptors (NLRs). Activation of TLR2 and TLR4 has been shown to lead to proinflammatory response in adipocytes, which is shown to suppress adipocyte differentiation and stimulate lipolysis, one of the major physiological functions of adipocytes. However, the effects of NOD activation ...


Angiotensinogen Gene Silencing Reduces Lipid Accumulation And Inflammation In Cultured 3t3-L1 Adipocytes, Wenting Xin Carroll Aug 2012

Angiotensinogen Gene Silencing Reduces Lipid Accumulation And Inflammation In Cultured 3t3-L1 Adipocytes, Wenting Xin Carroll

Masters Theses

Obesity is characterized by metabolic complications which are related to several life-threatening diseases. Dysregulated inflammatory adipokines secretion from adipose tissue is believed as the major contributor to obesity-associated local and systemic inflammation, insulin resistance, and other metabolic dysfunctions.

Numerous studies in our lab and others pointed to the role of local adipose tissue renin-angiotensin system (RAS) in the pathogenesis of obesity, inflammation and insulin resistance. We hypothesized that adipocytes-derived angiotensinogen (Agt) played a critical role in adipogenesis and/or lipogenesis as well as adipose inflammation. To test, we established 3T3-L1 preadipocytes stably transfected with Agt-shRNA or scrambled sequence (Sc-shRNA). Transfected ...
