Inhibition Of The Thioesterase Activity Of Human Fatty Acid Synthase By 1,4- And 9,10-Diones, Herman H. Odens

Faculty Works

Fatty acid synthase (FASN) is the enzyme that synthesizes fatty acids de novo in human cells. Although FASN is generally expressed at low levels in most normal tissues, its expression is highly upregulated in many cancers. Consistent with this notion, inhibition of FASN activity has demonstrated potential to halt proliferation and induce cell death in vitro and to block tumor growth in vivo. Consequently, FASN is widely recognized as a valuable therapeutic target. In this report, we describe a variety of 1,4-quinones and 9,10- anthraquinones, including several natural compounds and some newly synthesized compounds, that potently inhibit the thioesterase (TE) …

Investigating Propargyl-Linked Antifolates In Inhibiting Bacterial And Fungal Dihydrofolate Reductase, Joshua Andrade

Honors Scholar Theses

Antimicrobial agents have been invaluable in reducing illness and death associated with bacterial infection. However, over time, bacteria have evolved resistance to all major drug classes as a result of selective pressure. The advancement of new drug compounds is therefore vital. The Anderson-Wright Lab has focused on developing potent and selective inhibitors of dihydrofolate reductase (DHFR), an enzyme key in cell proliferation and survival, in several pathogenic species. The lab has found that a set of compounds, known as propargyl-linked antifolates, are DHFR inhibitors that are both biologically effective and have strong pharmacokinetic properties.

The efficacy of novel propargyl-linked antifolates …

Six1 Overexpression Promotes Epithelial– Mesenchymal Transition And Malignant Progression In Models Of Cervical And Colon Cancer, Hanwen Xu

Theses and Dissertations

Inappropriate expression of embryonic genes, particularly homeodomain transcription factors, contributes to tumorigenesis and tumor progression. The overexpression of Six1, a member of the Six family of homeodomain transcription factors, has been found in various human cancers, and is associated with tumor progression and metastasis. We have previously determined that the expression of SIX1 mRNA increased during in vitro progression of human papillomavirus type 16 (HPV16)- immortalized human keratinocytes (HKc/HPV16) toward a differentiation-resistant (HKc/DR) phenotype. However, the mechanism(s) of how Six1 promotes HPV16- mediated transformation remain unknown. In this study, we explored the role of Six1 at early stages and late …

Investigation Of The Response And Repair Of Replication, Kathryn Brady

Theses and Dissertations

When a mammalian cell suffers DNA damage, DNA damage signaling responses and repair pathways are invoked. The phosphorylation of histone variant H2AX (γH2AX) and of replication protein A (pRPA) are two well-documented damage signals, marking double strand breaks and stalled replication forks, respectively. Inhibitors of thymidylate synthase (TS) and ribonucleotide reductase (RNR) are chemotherapeutics that act by depriving cells of the deoxynucleotides necessary for DNA synthesis, which causes damage. The response and repair pathways activated by these chemotherapeutics have been studied for a number of years but there remain unanswered questions as to how cancer cells perceive this damage, the …

Effects Of Hiv-1 Tat Protein On Structure, Function And Trafficking Of The Dopamine Transporter, Narasimha Murty Midde

Theses and Dissertations

The alarming rise in HIV-1 associated neurocognitive disorder (HAND) is, at least in part, associated with HIV-1 viral proteins shed from infected macrophages, including transactivator of transcription (Tat) despite the success of anti-retroviral therapies. The dopamine (DA) system is greatly involved in the progression of HAND and is influenced by psychostimulants like cocaine. The DA transporter (DAT), a key regulator of neurocognitive functions, is a major molecular target for both Tat and cocaine. Our lab previously reported that exposure to Tat decreases DA uptake through allosteric regulation and alters cocaine binding sites in DAT.

In this research project the hypothesis …

Hence, we studied the effect of global inhibition of the PDE4 pathway in two rat experimental stroke models, using the PDE4 inhibitor rolipram. Further, the specific role of the PDE4D isoform in ischemic stroke pathogenesis was studied using PDE4D knockout rats in experimental stroke. METHODS: Rats were subjected to either the …

The Role Of Ape/Ref-1 In Hepatocellular Carcinoma Progression, Zhen Yang, Sun Yang, Bobbye J. Misner, Feng Liu-Smith, Frank L. Meyskens

Pharmacy Faculty Articles and Research

Hepatocellular carcinoma (HCC) is responsible for a third of the estimated cancer-caused deaths worldwide. To deeply understand the mechanisms controlling HCC progression is of primary importance to develop new approaches for treatment. Apurinic/apyrimidinic endonuclease-1/redox effector factor 1 (APE/Ref-1) has been uncovered elevated in various types of cancer, including HCC. Additionally, HCC progression is always correlated with elevated copper (Cu). Our previous data demonstrated that Cu treatment initiated APE/Ref-1 expression and its downstream targets. Therefore, we hypothesized that APE/Ref-1 may be involved in HCC progression through mediating the effect of Cu to its signaling cascades. Following different treatments, human HCC cell …

Exploring The Effect Of Solution Speciation On Crystallization Outcome, David M. Harvey, Arjun Kalra, Tonglei Li

The Summer Undergraduate Research Fellowship (SURF) Symposium

In the field of pharmaceuticals, the crystallization process significantly impacts the purity, morphology and polymorphism of active pharmaceutical ingredients (API), all of which are important in drug development. Polymorphism is the existence of more than one solid-state form of the same chemical entity. Tolfenamic acid (TFA), a Non-Steroid Anti-inflammatory drug (NSAID), has been shown to exhibit a unique physical phenomenon called concomitant polymorphism, whereby two polymorphs crystallize from the solution simultaneously. From previous work, it has been established that solution speciation i.e. the presence of monomers or dimers of TFA in solution is concentration and temperature dependent. This study correlates …

Building A Metabolic Bridge Between Glycolysis And Sphingolipid Biosynthesis : Implications In Cancer., Morgan L. Stathem

Electronic Theses and Dissertations

Cancer therapeutics has seen an emergence and re-emergence of two metabolic fields in recent years, namely bioactive sphingolipids and glycolytic metabolism. Anaerobic glycolysis and its role in cancer has been recognized in cancer biology over 90 years. In recent decades, the role of sphingolipids in cancer cell metabolism has gained recognition, notably ceramide’s essential role in programmed cell death and the role of the glucosylceramide synthase (GCS) in chemotherapeutic resistance. Despite this knowledge, a direct link between these two fields has yet to be concretely drawn. Herein, we show that in a model of highly glycolytic cells, generation of the …

Inducible Tumor Difference Between Rapid And Slow Rat Nat2 Congenic Fischer 344 Rats Administered Methyl-Nitrosourea., Marcus W. Stepp

Evaluation Of The Safety And Pharmacokinetic Profile Of The Broad Spectrum Antiviral Lectin Griffithsin., Christopher Lynn Barton

Electronic Theses and Dissertations

Carbohydrate binding agents that target viral envelope glycans are being studied for their potential use as microbicides and antiviral therapeutics. Griffithsin is a lectin originally identified in a red alga Griffithisia sp. Multiple studies have shown that GRFT inhibits HIV-1, Coronaviruses, Hepatitis C, influenza and Ebola virus replication in vitro. This antiviral activity suggests potential uses in chemoprophylaxis and disease treatment. However, safety of GRFT administration has not been extensively studied. In vivo testing--chronic subcutaneous treatment as well as single dose subcutaneous, oral, and intravenous administrations of Griffithsin in Sprague Dawley Rats (Rattus Norvegicus)--was used to assess Griffithsin’s pharmacokinetic properties …

Bone Strength And Architecture : Pharmacological Targeting Of Camkk2 As A Method For Enhancing Bone Quality., Zachary James Pritchard

Electronic Theses and Dissertations

Mice lacking or pharmacologically inhibited for calcium/calmodulin-dependent protein kinase kinase 2 (CaMKK2) have enhanced bone mass and microarchitecture. This enhanced bone mass and architecture is due to changes in osteoblast and osteoclast numbers as well as activity. Whether the enhanced bone mass translated to increased bone quality and strength was further explored by developing a method to directly test the trabecular strength of the distal femur. Micro computed tomography (CT)-based measurement of the length of the epiphysis of the distal femur, aided in its removal, allowing the exposure of the trabecular bone volume used to determine the microarchitecture parameters. Following …

Yokel, Jason M. Unrine, Burtron H. Davis, Alan K. Dozier, Sarita S. Hardas, Rukhsana Sultana, Eric A. Grulke, D. Allan Butterfield

Pharmaceutical Sciences Faculty Publications

The cytotoxicity of ceria ultimately lies in its electronic structure, which is defined by the crystal structure, composition, and size. Despite previous studies focused on ceria uptake, distribution, biopersistance, and cellular effects, little is known about its chemical and structural stability and solubility once sequestered inside the liver. Mechanisms will be presented that elucidate the in vivo transformation in the liver. In vivo processed ceria reveals a particle-size effect towards the formation of ultrafines, which represent a second generation of ceria. A measurable change in the valence reduction of the second-generation ceria can be linked to an increased free-radical scavenging …
