Expression And Purification Of Hpep Inhibitor Peptide, Olivia Plaza
Expression And Purification Of Hpep Inhibitor Peptide, Olivia Plaza
Undergraduate Research Conference
The enzyme human prolyl peptidase, or hPEP, has been linked to many processes within the brain, including breaking down neural peptides. A bovine milk protein, a-s1-casein (see above), has been found to inhibit hPEP in colon cancer cells. A 68 amino acid long section (bolded) of a-s1- casein containing the inhibitor region was cloned. The casein fragment expression was optimized for expression of the peptide. The purpose for optimizing expression is to have much of it on hand to utilize in further studies on its inhibitory properties on hPEP. By using this fragment of casein, one can study the structure …
A Novel Molecular And Cellular Study On Curcumin, Khang Nguyen
A Novel Molecular And Cellular Study On Curcumin, Khang Nguyen
Undergraduate Research Conference
Since the discovery of G-quartet (G4)by M. Gellertin 1962, much attention has been given on G4and C4(also called i-motif) as important drug design targets for the treatment of various human disorders. G4 forming sequences are prevalent in human genome, which includes many important regions of the eukaryotic genome, such as telomere ends, regulatory regions of many oncogenes c-kit, proto-oncogene c-myc, Kirsten rat sarcoma viral oncogene homolog (KRas). Curcumin(diferuloylmethane), an antiinflammatory and antioxidant compound, is found in the rhizomes of the plant Curcuma longa. The phytopolyphenolic chemical curcumin has been in the prominence due to its diverse pharmacological activities. Here, we …
Study Of Potential Drug For Alzheimer’S Disease: Small Organic Molecules, 1,5-Dhn And Tmpyp Inhibit Amyloid-Β Peptide Aggregation And Quench Hydroxyl Radicals, Matthew Murphy
Undergraduate Research Conference
Alzheimer disease (AD) is recognized as the six leading cause of the death in the United States. As of now, there is no cure for this fatal disease. The current treatment methods can only temporarily slow the worsening of symptoms. Research data suggested that an excess generation of hydroxyl radical in the brain causing the aggregation of Amyloid-β (Aβ) peptide which is considered to be responsible for Alzheimer's disease. Thus, there is a pressing need to find a suitable drug which can quench hydroxyl radicals effectively and stop or slow down the formation of aggregation of Aβ peptide. The primary …

Arachidin 3 Modulation Of Lipid Metabolism In Rotavirus Infections, Stormey Wisdom
Arachidin 3 Modulation Of Lipid Metabolism In Rotavirus Infections, Stormey Wisdom
Electronic Theses and Dissertations
Rotavirus (RV) can cause severe and deadly gastroenteritis in young children, infants, and immunocompromised individuals. Previous studies have shown that arachidin 3 (A3) inhibits RV replication, and that RV replication is dependent on the presence of lipids. This study investigated the alteration of lipid metabolism by A3 in RV infected HT29.f8 cells. A decrease in the RV regulation of lipid biosynthesis genes was observed with the addition of A3 using qRT-PCR. Also, immunofluorescent and histochemical staining for neutral fats, a major component of cellular lipid droplets, revealed an increased accumulation with both RV and RV+A3 when compared to no virus …
Chemophobia And The Relation To Names, Justin Crow
Chemophobia And The Relation To Names, Justin Crow
Undergraduate Research Conference
Chemophobia is a recently identified cultural phenomena where people are afraid of chemicals in their lives, whether "chemicals" are in their food, their medicines, vaccinations, and other products. An increasing amount of people have a concern about the risk associated with chemicals in their everyday life. Chemistry professionals find this a bit strange as Chemistry states that all matter is made up of chemicals. Chemistry has many systems of naming and understanding chemicals which can exclude people from understanding the risk or lack thereof attributed to materials that are common in daily life. This effect could be accentuated by educational …
Adhd Medication: To Medicate Or Not To Medicate?, Alyssa Henderson
Adhd Medication: To Medicate Or Not To Medicate?, Alyssa Henderson
Undergraduate Research Conference
Eleven percent of American children are diagnosed with at least one type of ADHD. That is 6.4 million children that are clinically diagnosed with the inability to focus attentively, restlessness, imbalanced mood swings and under-developed social skills. All of these lead to any learning environment being a daily battleground in the children both internally as well as externally. This is caused due to an under-activity in the frontal lobe of the child’s brain, which is responsible for their planning, motivation, social behavior and speech production. The symptoms associated with ADHD are currently being combated with the utilization of stimulants known …

Motivation: Transcriptome-based computational drug repurposing has attracted considerable interest by bringing about faster and more cost-effective drug discovery. Nevertheless, key limitations of the current drug connectivity-mapping paradigm have been long overlooked, including the lack of effective means to determine optimal query gene signatures. Results: The novel approach Dr Insight implements a frame-breaking statistical model for the ‘hand-shake’ between disease and drug data. The genome-wide screening of concordantly expressed genes (CEGs) eliminates the need for subjective selection of query signatures, added to eliciting better proxy for potential disease-specific drug targets. Extensive comparisons on simulated and real cancer datasets have validated the …
Endocidal Regulation Of Secondary Metabolites In The Producing Organisms, Shiyou Li, Ping Wang, Wei Yuan, Zushang Su, Steven H. Bullard
Endocidal Regulation Of Secondary Metabolites In The Producing Organisms, Shiyou Li, Ping Wang, Wei Yuan, Zushang Su, Steven H. Bullard

Secondary metabolites are defined as organic compounds that are not directly involved in the normal growth, development, and reproduction of an organism. They are widely believed to be responsible for interactions between the producing organism and its environment, with the producer avoiding their toxicities. In our experiments, however, none of the randomly selected 44 species representing different groups of plants and insects can avoid autotoxicity by its endogenous metabolites once made available. We coined the term endocides (endogenous biocides) to describe such metabolites that can poison or inhibit the parent via induced biosynthesis or external applications. Dosage-dependent endocides can selectively …

Rotavirus (RV) infections cause severe diarrhea in infants and young children worldwide. Vaccines are available but cost prohibitive for many countries and only reduce severe symptoms. Vaccinated infants continue to shed infectious particles, and studies show decreased efficacy of the RV vaccines in tropical and subtropical countries where they are needed most. Continuing surveillance for new RV strains, assessment of vaccine efficacy, and development of cost effective antiviral drugs remain an important aspect of RV studies. This study was to determine the efficacy of antioxidant and anti-inflammatory stilbenoids to inhibit RV replication. Peanut (A. hypogaea) hairy root cultures were induced …

Chemical constituents of various tissues of turmeric (Curcuma longa L.) have been extensively investigated. To date, at least 235 compounds, primarily phenolic compounds and terpenoids have been identified from the species, including 22 diarylheptanoids and diarylpentanoids, eight phenylpropene and other phenolic compounds, 68 monoterpenes, 109 sesquiterpenes, five diterpenes, three triterpenoids, four sterols, two alkaloids, and 14 other compounds. Curcuminoids (diarylheptanoids) and essential oils are major bioactive ingredients showing various bioactivities in in vitro and in vivo bioassays. Curcuminoids in turmeric are primarily accumulated in rhizomes. The essential oils from leaves and flowers are usually dominated by monoterpenes while those from …

Reactivity of factor IXa with basic pancreatic trypsin inhibitor is enhanced by low molecular weight heparin (enoxaparin). Previous studies by us have suggested that this effect involves allosteric modulation of factor IXa. We examined the reactivity of factor IXa with several isolated Kunitz-type inhibitor domains: basic pancreatic trypsin inhibitor, the Kunitz inhibitor domain of protease Nexin-2, and the first two inhibitor domains of tissue factor pathway inhibitor. We find that enhancement of factor IXa reactivity by enoxaparin is greatest for basic pancreatic trypsin inhibitor (>10-fold), followed by the second tissue factor pathway inhibitor domain (1.7-fold) and the Kunitz inhibitor …
