The Effects Of An Adenosine A(2a) Agonist As An Adjunctive Treatment To Alleviate Sensorimotor Gating Deficits In A Rodent Model Of Schizophrenia, Hannah Rauhuff
Undergraduate Honors Theses
The adenosine system has become a promising target for the treatment of schizophrenia due to its unique relationship with dopamine D2 receptors. Dopamine D2 receptors display heightened sensitivity in schizophrenia, and inhibition of these receptors has been shown to alleviate some of the psychotic symptoms of the disorder. Inhibition of adenosine A(2A) receptors has been shown to decrease dopamine D2 receptor sensitivity, making this receptor a potential target for treatment of the disorder. This effect occurs because adenosine A(2A) receptors form a mutually inhibitory heterodimeric complex with dopamine D2 receptors. The present study looked at the …
Anti-Neoplastic Effects Of Extracts From Gnaphalium Gracile On Colon, Pancreatic, And Prostate Cancer Cells, Joshua R. Canter
Anti-Neoplastic Effects Of Extracts From Gnaphalium Gracile On Colon, Pancreatic, And Prostate Cancer Cells, Joshua R. Canter
Undergraduate Honors Theses
Over 4,000 flavonoids have been identified, and among these, many of them are known to possess cardioprotective, anti-inflammatory, antimicrobial, and antitumor effects. However, most of these properties have yet to be fully understood. In this study, extracts from Gnaphalium gracile, thought to possess a mixture of flavonoids, have been tested for cytotoxic activity on pancreatic (MiaPaca, Panc28), colon (HCT-116, Caco-2), and prostate (PC3, LNCaP), cancer cell lines. Polar extracts from the leaves of G. gracile have the most cytotoxic effect on these cancer cell lines, particularly the prostate cancer cell lines PC3 and LNCaP. Evidence suggests the extracts have …
Redesign Of Trans-Splicing Molecules For The Correction Of Dystrophia Myotonica Type 1 Toxic Rna Transcripts, Eleanor G. Harrison
Redesign Of Trans-Splicing Molecules For The Correction Of Dystrophia Myotonica Type 1 Toxic Rna Transcripts, Eleanor G. Harrison
Undergraduate Honors Theses
Dystrophia myotonica (DM1), one of the most common forms of muscular dystrophy, is caused by a repeated trinucleotide expansion in the DMPK gene. This mutation results in the accumulation of toxic cellular RNA transcripts. Spliceosome-mediated RNA trans-splicing (SMaRT) technology is a form of gene therapy that possesses the potential to correct these toxic RNA transcripts and thus cure the disease. Despite its promise, prior research applications of SMaRT technology to DM1 have been hampered by poor efficiency and have not been validated in a relevant model of the disease. In order to improve the efficiency of trans-splicing, this study examined …
A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard
A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard
Undergraduate Honors Theses
In this study, three different chromatographic column chemistries (C18, Pentafluorophenyl (PFP), Hydrophilic Interaction Chromatography (HILIC)) were compared under optimal conditions to determine which stationary performed best in the separation and detection of a mixture of opioids using LC-MS. Furthermore, these stationary phases were examined in three different column technologies – traditional silica, porous shell, and porous polymer (PRP). The PRP column had the best peak shape for all 13 opioids and dominated for later-eluting compounds. In terms of column reproducibility, the Hamilton C18 column had the lowest %RSD values. The Kinetex HILIC produced the most theoretical plates and best resolution …
The Study Of The Effect Of Two Flavone Isomers Derived From Gnaphalium Elegans And Achyrocline Bogotensis In Breast Cancer., Jessica J. Walker
The Study Of The Effect Of Two Flavone Isomers Derived From Gnaphalium Elegans And Achyrocline Bogotensis In Breast Cancer., Jessica J. Walker
Undergraduate Honors Theses
Flavonoids are ubiquitous to all terrestrial plants and many are known to have anti-tumor activities. In this research project we studied the differential cytotoxic effects of two flavone isomers on human breast cancer cells (BT-474, SKBR-3, and MCF-7) and normal breast cells as a control (MCF-10A). The basis of the relationships between chemical structures, type and position of substituent groups and the effects these compounds exert specifically on cancer cells are not completely elucidated. These flavones are derived from plants native of Colombia, South America. These plants of the family Asteraceae, genera Gnaphalium and Achyrocline are reputed to have anti-cancer …
7,8-Dihydroxyflavone, A Selective Tyrosine Kinase Receptor B Agonist And Bdnf Mimic, Promotes Angiogenesis., Jeremy Williams
7,8-Dihydroxyflavone, A Selective Tyrosine Kinase Receptor B Agonist And Bdnf Mimic, Promotes Angiogenesis., Jeremy Williams
Undergraduate Honors Theses
7,8-dihydroxyflavone (7,8-DHF), which is a member of the flavonoid family, is a selective tyrosine kinase receptor B (TrkB) agonist that has neurotrophic effects in various neurological diseases such as ischemic stroke and Parkinson’s disease [3]. In this study, we assessed the angiogeneic effect of 7,8-DHF in endothelial cells derived from resistance vessel of the brain. Angiogenesis by 7,8-DHF is an important factor that helps prevent and treat various ischemic diseases. In this study, we found that rat RV cells used in the experiment possess the TrkB receptor. Our data also demonstrates that 7,8-DHF is able to stimulate cell proliferation in …
