Quantitation Of Mycophenolic Acid And Metabolites By Uplc-Ms/Ms In Renal Transplant Patients, Yun-Fen Huang, Ya-Ching Huang, Hsiao-Chen Ning, Chia-Ni Lin

Journal of Food and Drug Analysis

Mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), specific inhibitors of lymphocyte proliferation, are commonly used as adjuvant therapy with calcineurin inhibitor agents after kidney transplantation. After administration, MMF and EC-MPS are hydrolyzed to mycophenolic acid (MPA), the active form of the drug, which must be monitored due to its narrow therapeutic window, drug–drug interactions, and large intra-and inter-individual pharmacokinetic variability despite a fixed dose. Monitoring plasma MPA level is recommended to maintain the drug within the therapeutic window, optimize its efficacy, and minimize side effects. This study aims to develop a method for quantifying MPA and its major metabolites …

Camphorataimide B Suppresses The Metastasis Of Human Colorectal Cancer Cell By Inhibiting Smad/Fak/Akt Axis And Promoting Degradation Of Snail/Bmp4 Complex, Chi-Chou Huang, Chia-Hung Hung, Yi-Ju Lee, Tsui-Hwa Tseng, Yean-Jang Lee, Shao-Hsuan Kao, Chau-Jong Wang

Journal of Food and Drug Analysis

Camphorataimide B (CamB) has anticancer activities against several tumors. Here, we aimed to investigate the mechanism(s) by which CamB inhibits metastasis of colorectal cancer (CRC) cells. Low-dose CamB did not affect the cell viability and cell cycle progression of CRC cells, but significantly inhibited the metastatic potentials of CRC cells. Mechanically, CamB reduced the protein and mRNA expression of BMP4, and inhibited Smad and FAK/Src/Akt signaling. CamB also decreased Snail levels by promoting its degradation via proteasome and thereafter reduced Snail-mediated BMP4 transcription. Moreover, CamB considerably inhibited the in vivo metastasis of DLD-1 cells in xenograft mice.

Interactions Between Soft Nanoparticles And Mammalian Cells, Mitchell Raith

Doctoral Dissertations

Nanoparticles have been of interest to the pharmaceutical industry since the 1980s. The first FDA approved nanoparticle-based therapies included liposomal anesthesia agents. Since then, the amount of FDA-approved nanoparticle therapies remains low. This is because nanoparticle-patient interactions can be very complex and are not well understood. Complicating factors also include increasing obesity rates among the patient population and many small animal pre-clinical trials are completed with healthy, lean animals. The biochemical differences between lean and obese patients prevents early studies from accurately predicting nanoparticle clinical behaviors. Many nanoparticles fail in trails. In this thesis, I aimed to uncover how nanoparticles …

Regaining Effort-Based Food Motivation: The Drug Methylphenidate Reverses The Depressive Effects Of Tetrabenazine In Female Rats, Deanna Pietrorazio

Honors Scholar Theses

Tetrabenazine (TBZ), a vesicular monoamine transporter type 2 (VMAT-2) inhibitor, depletes dopamine and induces motivational deficits and other depressive symptoms in humans. Methylphenidate (MPH) is a dopamine transport blocker that is used to enhance motivational function. Previous studies have shown that in male rats, TBZ induces a shift in effort-related choice such that a low-effort bias is induced. In male rats this occurs at a dose range of 0.75-1.0 mg/kg TBZ, and this effect is reversible with co-administration of MPH. Recent studies have shown that females need a higher dose of TBZ (2.0 mg/kg) to show the low-effort bias. The …

Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan

Electronic Theses and Dissertations

Retinal fibrosis is detrimental to vision. Retinal pigment epithelial (RPE) cells contribute to several retinal fibrotic diseases. Upon exposure to TGF-β, a key fibrotic cytokine, RPE cells trans-differentiate to myofibroblasts marked by the integration of α-SMA fibers into F-actin stress fibers, which confer strong contractility. Myofibroblasts produce and contract the collagen-rich fibrotic scar and disrupt retinal architecture. In this study, we investigated the in vitro effects of the putative endocannabinoid compound N-oleoyl dopamine (OLDA) on TGF-β2 induced porcine RPE cell contraction and α-SMA expression. Using an in vitro collagen matrix contraction assay, we found that OLDA inhibited TGF-β2 induced contraction …

Particulate Hexavalent Chromium Inhibits Homologous Recombination Repair By Targeting Rad51 Paralogs In Human Lung Fibroblasts., Aggie R. Williams

Electronic Theses and Dissertations

Hexavalent Chromium [Cr(VI)] is a known human lung carcinogen and general health hazard. The mechanism of carcinogenesis remains poorly understood, but chromosome instability (CIN) is the major theory in its carcinogenic mechanism. Homologous recombination (HR) repair is a DNA repair pathway that prevents CIN by repairing DNA double-strand breaks. RAD51, a key mediator protein of HR repair, along with the RAD51 paralogs (RAD51B, C, D, XRCC2, and 3) are required for HR repair. During HR, RAD51 loads and forms a helical nucleoprotein filament structure to promote DNA strand exchange and stimulate pairing activity of DNA. Cr(VI) exposures have been shown …

Buprenorphine Effects On Anxiety-Like Behavior In B6 Mice, Megan K. Thibert

Select or Award-Winning Individual Scholarship

Buprenorphine, a semi-synthetic opioid prescribed for the treatment of opioid use disorder (OUD), has been suggested as a potential pharmacological treatment for anxiety. Some preclinical and clinical studies provide support for the anxiolytic effects of buprenorphine, but research in this area is scarce, and findings to date have been mixed. The present study was designed to test the hypothesis that buprenorphine alters anxiety-like behavior in C57BL/IJ (B6) mice measured using the elevated zero maze (EZM). Adult, male mice (n=10) were given subcutaneous injections of saline (control) and three doses of buprenorphine (0.3, 1, and 10 mg/kg). One hour following injection, …

Exchange Protein Directly Activated By Camp (Epac1) Protects Human Endothelial Cells From Tumor Necrosis Factor-⍺ (Tnf-⍺) Induced Cell Death, Anh Luu, Abigail Carpenter, Rosetta Tolley

ONU Student Research Colloquium

Millions of people are affected by diseases involving inflammatory states such as sepsis. Sepsis is associated with elevated tumor necrosis factor alpha (TNF-⍺) which mediates inflammation. Excessive TNF-⍺ contributes to death of endothelial cells (EC) with subsequent disruption of vascular endothelial function. Exchange Factor Directly Activated by cAMP (EPAC1) is a cyclic-AMP (cAMP) sensor that regulates multiple EC functions. We hypothesized that EPAC1 activation affects the response of EC to TNF-a. Microvascular EC were pretreated for 45 minutes with 100 mM 8-pCPT-2′-O-Me-cAMP (8-CPT, specific EPAC1 activator) or 10 mM forskolin (adenylyl cyclase activator that increases cAMP), then exposed to 5 …
