Anti-Neuroinflammatory Effects And Underlying Mechanismsof Cleistocalyx Nervosum Var. Paniala Extracts In Microglia Cells, Sakawrat Janpaijit

Chulalongkorn University Theses and Dissertations (Chula ETD)

Sustained inflammatory responses have been implicated in various neurodegenerative disorders. Cleistocalyx nervosum var. paniala (CN), an edible berry, has been reported to exhibit several beneficial properties. However, only limited research is available on this fruit seed, which is classified as agricultural food waste. We therefore focused on the anti-neuroinflammatory effects and underlying mechanism of C. nervosum var. paniala seed extract (CNSE) on BV-2 mouse microglial cells induced by lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-α). CN seeds were extracted in 95% ethanol by Soxhlet extraction. HPLC was carried out to identified resveratrol (RESV) in CNSE. For cell-based studies, the expression …

Chitosan is one of the polymers commonly used for this purpose due to their higher water retention and porosity, which create space for loading medicine into the matrix. However, the potential utilization of endogenous and exogenous stimuli controlling drug release still …


The Influence Of Extracellular Matrix On Human Periodontal Ligament Stem Cell Properties, Daneeya Na Nan Jan 2022

The Influence Of Extracellular Matrix On Human Periodontal Ligament Stem Cell Properties, Daneeya Na Nan

Chulalongkorn University Theses and Dissertations (Chula ETD)

The periodontal ligament (PDL) is a crucial tissue connecting teeth to surrounding alveolar bone, withstanding the mechanical forces of mastication, speech, and deglutition. The extracellular matrix (ECM) of the PDL plays a critical role in maintaining PDL cell stability and function in response to external forces. Mechanotransduction, the process by which cells convert mechanical signals into biochemical signals, is essential for PDL cells to sense and respond to mechanical stimuli. The ECM is a critical mediator of mechanotransduction, as it is responsible for transmitting mechanical forces to cells and regulating cellular responses to mechanical stress. Matricellular proteins, such as periostin …

Deciphering The Role Of Mitochondrial Physiology And Thermal Acclimation In Shaping Whole Organismal Performance Of An Invasive Forest Pest, Essa Alrashdi Jan 2022

Deciphering The Role Of Mitochondrial Physiology And Thermal Acclimation In Shaping Whole Organismal Performance Of An Invasive Forest Pest, Essa Alrashdi

Masters Theses

Environmental factors such as temperature are substantial determinants of the spongy moth, L. dispar, distribution, reproduction, and growth. Accumulating energy reserves at the larval stage is particularly important to L. dispar, since the larvae metamorphose into a fully-grown, non-feeding adult. As non-feeding adults, the energy balance of the pupae must be adequate, to ensure enough energy reserves for adult dispersal, egg maturation and overall persistence of the species in the region. At this stage, environmental temperature also determines daily metabolic demands, and the overall cost of sustaining ecologically relevant activities. Various hypotheses describing a mismatched growth and metabolic …

Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff Jan 2022

Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff

Masters Theses

Understanding environmental conditions that support bigheaded carp (Hypophthalmichthys sp.) reproduction in tributary rivers provides key predictions of their invasion throughout the United States. Past research, primarily in larger order rivers, identified factors such as discharge, temperature, and turbidity as main environmental drivers of bigheaded carp reproduction. I used the variable hydrologic conditions between the Illinois and Wabash Rivers to compare environmental conditions between tributaries of each basin, determine which conditions influence bigheaded carp reproduction in tributaries, and predict tributaries likely to support bigheaded carp reproduction. Three tributaries of the Illinois and Wabash Rivers were sampled for ichthyoplankton from …


Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe Jan 2022

Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe

Masters Theses

Black Crappie Pomoxis nigromaculatus and Bluegill Lepomis macrochirus are popular sportfishes that co-occur in similar bodies of water throughout most of the Central and Eastern United States but have distinct thermal physiologies. L. macrochirus is often found in warmer regions of freshwater reservoirs, where P. nigromaculatus tends to exploit cooler regions, especially in power plant cooling reservoirs. The coal-fired Coffeen Power Station ceased energy production in October 2019, providing an ideal scenario to study the organismal effects of the sudden shift in thermal regime. Previous studies showed that P. nigromaculatus inhabited the less thermally-impacted areas of Coffeen Lake, whereas L. …

The Role Of Irf-1 In Spontaneous Mouse Glioma, Aakash B. Vaidya Jan 2022

The Role Of Irf-1 In Spontaneous Mouse Glioma, Aakash B. Vaidya

Theses and Dissertations

Glioblastoma Multiforme has been shown to be one of the deadliest primary brain cancers. One of the reasons why GBM is so deadly, is a unique immunosuppressive tumor microenvironment that promotes GBM growth and progression. Both astrocyte and microglia have been implicated in immunosuppression. In this study, we explored the role of Interferon Regulatory Factor 1 (IRF-1) in astrocytes and glioma cells on the growth of spontaneous glioma tumors. IRF-1 is regulated by the JAK/STAT pathway and induces expression of Programmed death ligand 1 (PD-L1). PD-L1 downregulates immune responses to glioma. We found that IRF-1 had no effect on spontaneous …

Progress Towards Next Generation Modulators Of Ctbp's Oncogenic Effects, Jacqueline L. West Jan 2022

Progress Towards Next Generation Modulators Of Ctbp's Oncogenic Effects, Jacqueline L. West

Theses and Dissertations

Human C-terminal binding proteins (CtBP1 and CtBP2) are transcriptional coregulators of multiple genes in the human genome, including tumor suppressor genes (e.g., Bik, PTEN, BRCA1, and E-cadherin) as well as oncogenes (e.g. MDR1 and Tiam1). Both homologues of CtBP are overexpressed in many types of cancer, including breast cancer (92%), ovarian cancer (83%), colorectal cancer (64%), hepatocellular carcinoma (60%), gastric cancer, prostate cancer, and pancreatic adenocarcinoma. Further, expression levels of CtBP correlate with worse prognostic outcomes and more aggressive tumor features because it promotes proliferation, epithelial-mesenchymal transition, and cancer stem cell self-renewal activity.

Our laboratory has identified a lead inhibitor …

Targeting Bcl-2 Family Proteins In Therapy Induced Senescent Cancer Cell Models, Wade Cook

Theses and Dissertations

Non-small Cell Lung Cancer (NSCLC) originates from numerous different cell types in the lungs and is among the deadliest of cancers. Head and Neck Squamous Cell Carcinomas (HNSCC) are derived from the mucosal membranes of the oral cavity, pharynx, and larynx. Both NSCLC and HNSCC are predominately caused by tobacco smoke inhalation and as such mutations in the tumor suppressor gene TP53 are common. Since similarities exist in the root cause of NSCLC and HNSCC, they may also share similarities in treatment methods. Cisplatin is a platinum-based DNA damaging agent that has been used as a cancer chemotherapy for decades. …


Evaluating Population Genetic Structure And Potential Genomic Signals Of Natural Selection In A Migratory Songbird (Protonotaria Citrea), Tyler A. Hohenstein Jan 2022

Evaluating Population Genetic Structure And Potential Genomic Signals Of Natural Selection In A Migratory Songbird (Protonotaria Citrea), Tyler A. Hohenstein

Theses and Dissertations

In this study I attempted to further resolve the population genetic structure in the Prothonotary Warbler (Protonotaria citrea), and conducted an outlier SNP analysis and exploratory gene ontology analysis to investigate potential ongoing natural selection in the species. This analysis of population structure confirms previous work by DeSaix et al. (2019), where weak population structure was observed between eastern sites along the Atlantic Coastal Plain, and western sites in the Mississippi Alluvial Valley, possibly due to a genetic discontinuity across the Appalachian Mountains. I conducted two forms of outlier SNP analyses, a principal component analysis (PCA)-based approach to identify SNPs …

Differential Progression Of Unhealthy Diet-Induced Hepatocellular Carcinoma In Obese And Non-Obese Mice, Emma Hymel, Elizabeth M. Vlock, Kurt W. Fisher, Paraskevi A. Farazi

Journal Articles: Epidemiology

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) ranks first among liver diseases in Western countries. NAFLD is typically associated with obesity and diabetes, however it also develops in lean individuals without metabolic syndrome. The prevalence of lean NAFLD is 7 percent in the U.S. and 25-30 percent in some Asian countries. NAFLD starts with excess liver fat accumulation (NAFL), progresses to nonalcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC). The pathogenesis of lean NASH-HCC and how it differs from obese NASH-HCC is not well understood.

METHODS: In this work, we generated a mouse model of lean and obese NASH-HCC using a …

Willingness To Pay For Mangroves’ Coastal Protection: A Case Study In Santo Angel, Calauag, Quezon, Philippines, Wesley Gagarin, Decibel F. Eslava, Rico Ancog, Cristino L. Tiburan Jr, Noelynna Ramos

Forest and Society

The mangroves in Santo Angel in the municipality of Calauag, Quezon Province in the Philippines, provide a wide array of ecological services that range from provisioning of resources and habitat to various floral and faunal species to regulating services including coastal protection. Coastal protection from mangroves is needed by the local community as Santo Angel is susceptible to typhoons and storm surges. However, the mangrove’s ability to provide coastal defense has considerably declined in the past decades due to overexploitation. Using the double-bounded dichotomous choice contingent valuation method, the willingness to pay (WTP) of the local community for a hypothetical …
