Upregulation Of The Predominant Cystic Fibrosis Causing Mutation Df508-Cftr By Triazole Compounds In Epithelial Cells, Maggie Taylor
Upregulation Of The Predominant Cystic Fibrosis Causing Mutation Df508-Cftr By Triazole Compounds In Epithelial Cells, Maggie Taylor
Undergraduate Research Conference
Cystic fibrosis is a common genetic disease that is caused by a mutation in the plasma membrane protein CFTR, which stands for Cystic Fibrosis Transmembrane-conductance Regulator. When this membrane protein is mutated, it impairs its chloride ion channel function, blocking the movement of chloride ions that travel in and out of the cell. Previous studies have demonstrated that the most prevalent CFTR mutation, ∆F508-CFTR, can be partially reversed using small molecules (Heda and Marino, BBRC, 271:659-664, 2000). In this study, I have investigated the effects of several triazole compounds known to bind and transport chloride ions in cultured cells, on …
Effects On Primary Endothelial Cells When Exposed To Polyethylene Terephthalate Nanoplastic, David Guzman
Effects On Primary Endothelial Cells When Exposed To Polyethylene Terephthalate Nanoplastic, David Guzman
Seaver College Research And Scholarly Achievement Symposium
As the use of plastics becomes more predominant in our environment, the interactions between nanoplastics and the human body have increased dramatically. One of the most common and prevalent plastics is polyethylene, and more specifically polyethylene terephthalate (PET). Tissue exposure to nanoplastics occurs through surface contact upon ingestion or inhalation where nanoplastics can pass readily through the epithelial layer. Directly beneath gut and lung epithelia is the endothelial layer of capillaries. Very little is known about the interactions between polyethylene and human cells, with no information currently available on its effects with the endothelial layer. Our previous research showed that …

From Soap Bubbles To Cell Membranes, Peter Beltramo
From Soap Bubbles To Cell Membranes, Peter Beltramo
Science and Engineering Saturday Seminars
Have you ever blown a soap bubble and wondered - what causes the bubble to be so stable and produces those colorful reflections of light? The answer lies in a class of molecules known as surfactants, and they have remarkable similarities with the molecules that comprise the cell membrane of all living organisms. In this workshop, we will use the analogy of a soap bubble to describe cellular membrane properties such as chemistry, structure, membrane transport, and ion channel formation. The goals of this workshop are to 1) link initially intractable concepts in biology like intracellular transport to the intuitive …

Hexavalent Chromium: Elucidating Its Carcinogenic Mechanism, And Testing Potential Preventative Treatments, Ryan Himes, Timothy Mayotte
Scholar Week 2016 - present
Cr(VI) (hexavalent chromium) has recently been found in the drinking water of over 250 million Americans. It is a powerful oxidizing agent, and is known to cause cancer, although the specific mechanism has yet to be elucidated. There is no known preventative treatment for Cr(VI) exposure, and the US EPA is currently determining what concentration of Cr(VI) in drinking water can be safely tolerated. This study sought to test the hypothesis that Cr(VI) cytotoxicity can be prevented by various antioxidants. We tested this hypothesis by exposing human embryonic kidney and human intestinal epithelial cells to Cr(VI), with and without the …
Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost
Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost
Scholar Week 2016 - present
Breast carcinoma is the most frequently diagnosed cancer among women and causes over 400,000 deaths yearly worldwide. Current treatments such as chemotherapy are not selective for cancerous tissues but are destructive to normal tissues as well. This causes a range of side effects including pain, nausea, hair loss, weakness, and more. Inactivation of p53 is an almost universal mutation within human cancer cells. The ability to activate the p53 pathway which protects cells from tumor formation is lost in 50% of cancers. Due to the prevalence of this mutation, p53 is a uniquely valuable target for applied research. Alpha mangostin …

Investigating The Impact Of Oxidative Stress On Tetrahymena Thermophila Sirtuin,Thd 18, Emmanuel Dubuisson
Publications and Research
Sirtuins are a family of enzymes that fulfill various important biological functions. Investigators have looked for the implication of Sirtuin genes in cell signaling mechanisms, in the formation and silencing of heterochromatin, in the regulation of ion channels, and in the modulation of the cellular redox reactions[2]. Different model organisms have been previously used to conduct these studies; among them, there are yeasts, nematodes, and fruit flies. Each one has made some valuable contribution into the vast body of knowledge related to this field.
However, gaps in the understanding of Sirtuins functions still remain to be filled. In this optic, …

Protein prenylation is a post-translational modification that involves the addition of lipid groups to the end of a target protein and is necessary for protein activity. Prenylation has important roles in the cell: targeting and localizing proteins to subcellular compartments and promoting protein-protein interactions. Recently, we have found Protein Prenyltransferase Alpha Subunit-like (PPAL), which shares structural similarities to known prenylation enzymes. However, the biochemical function of PPAL is still unknown. PPAL is present in a single copy in other plants examined to date but is present in two copies in moss. Knockouts in our lab of either PpPAL1 or PpPAL2 …
Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard
Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard
Seaver College Research And Scholarly Achievement Symposium
Medicinal plants have historically been a valuable source of new drugs, and Southern California possesses a rich collection of native plants which have been used as medicines by native people groups for thousands of years. Angiogenesis is the biological process of new blood-vessel growth from endothelial cells. It is an essential part of the wound-healing process, and increased angiogenesis has also been implicated in the growth of some types of cancerous tumors. In this study, extracts of the Southern Californian native plants Red shanks (Adenostoma sparsifolium) and the alkaloid extract of Jimson weed (Datura wrightii) were …

Streptococcus mutans JH1140 is a strain of bacteria which produces a lantibiotic product, named mutacin 1140. Mutacin 1140 has been shown to be effective at inhibiting Gram-positive bacterial infections caused by Staphylococcus aureus and Streptococcus pneumoniae. Mutacin 1140 is a ribosomally synthesized peptide antibiotic that undergoes extensive posttranslational modifications (PTM). We have found that Mutacin 1140 and an aminoglycoside, Kanamycin, when combined together, act synergistically against Staphylococcus aureus. This was determined by performing serial kill curve dilution overlays on solid media, followed up with kill curve by microdilution plate, and most recently confirmed with kill curve CFU count plates …
Epigenetic Regulation Of Gene Expression During Spermatogenesis, Karishma Nayak
Epigenetic Regulation Of Gene Expression During Spermatogenesis, Karishma Nayak
Senior Honors Projects
In the US livestock production industry, improving reproductive efficiency will improve animal welfare and maintain reasonable costs of meat and milk for consumers. In recent research, abnormalities in epigenetic markers in sperm during spermatogenesis, has been linked to male subfertility in many species. Epigenetics is the study of changes in organisms caused by modifications of gene expression, including DNA methylation, rather than alteration of the genetic code itself. When this process is disturbed, it can negatively impact semen therefore decreasing its fertility. Through further research on how DNA methylation influences gene expression during spermatogenesis and its impact on sperm quality, …

Comparison Of Gene Ontology Term Annotations Between E.Coli K12 Databases, Reddysailaja Marpuri
Comparison Of Gene Ontology Term Annotations Between E.Coli K12 Databases, Reddysailaja Marpuri
Student Research Conference Select Presentations
The objective of this project was to get up-to-date functional information on all genes of E.coli K12 strains based on Genome Ontology terms. Gene Ontology is described by a defined library of terms related the biological process, cellular components and molecular functions of a gene in an organism. The genome sequence of an organism gains its value when it is annotated with gene ontology terms, which bridges the gap from the sequence to the biology of an organism. Since we use annotated gene database in the prediction of the function of newly sequenced genes, it is important to have databases …
