The Beta-Catenin/Muc1.Ct Interaction In Pancreatic Cancer, Edwin Wiest
The Beta-Catenin/Muc1.Ct Interaction In Pancreatic Cancer, Edwin Wiest
Theses & Dissertations
MUC1 is overexpressed in over 90% of pancreatic cancer cases, and its interaction with beta-catenin promotes progression of the disease. Various in vitro and in vivo methods show that beta-catenin and MUC1 interact by way of the cytoplasmic tail of MUC1 (MUC1.CT). This interaction occurs in the membrane of pancreatic cancer cells but is found to a smaller extent in the nucleus as well. Biophysical methods suggest that MUC1 interacts with beta-catenin through a sequence of amino acids in the tail of MUC1 that sit very near the transmembrane domain of MUC1. In pancreatic ductal adenocarcinoma cells, it appears that …
A Cytotoxic Evaluation Of A Chalcone Derivative Library On A549 Cells, Mary Elaine Kuo
A Cytotoxic Evaluation Of A Chalcone Derivative Library On A549 Cells, Mary Elaine Kuo
Undergraduate Theses
Chalcones, a precursor to flavonoids, are chemical compounds found naturally in plants. The chalcones’ structure consists of a ketone bridge attached to two aromatic rings. Varying substituents on the aromatic rings allow for different affects, including anti-cancer properties. As a Michael acceptor, chalcones interact with pathways that cause inhibition of the initiation, promotion, and progression of cancer tumors. We have screened 32 compounds for growth inhibition in lung cells that vary the flexibility and confirmation of the 3 carbon bridge between the two aromatic rings as well as the effects of electronic modifications to the aromatic ring. We have found …

Project I: Chemotherapeutic drugs have many side effects that are undesirable and are highly toxic. Therefore, there is a growing need for the development of drugs with enhanced efficacy, specificity, and potency to provide cancer patients with a better prognosis. It was discovered that a member of the Receptor Tyrosine Kinase family, EphA2, may prove to be a viable target in developing anti-cancer agents. In the presence of its ligand, EphA2 receptor is responsible for apoptotic and anti-migratory activity. However, in the absence of ligand, EphA2 is able to stimulate cell migration and therefore tumorigenic activity. These conflicting roles of …
Quantitative Analysis Of Bleomycin In Rat Plasma By Lc-Ms/Ms, Huawen Li
Quantitative Analysis Of Bleomycin In Rat Plasma By Lc-Ms/Ms, Huawen Li

Bleomycin is the most commonly used compound in its group of antineoplastic drugs. It works on tumor cells by single and double stranded DNA cleavage after its activation, in which it blocks tumor cells’ DNA replication or transcription activities to inhibit tumor cells’ growth. Bleomycin sulfate (Blenoxane) is the most popular preparation used in clinical research, and contains Bleomycin fractions of A2 and B2, which causes difficulties in quantitative analysis. This work uses the metal chelating property of Bleomycin as an advantage to simplify and improve sensitivity of existing quantitative methods. Copper was spiked in excess to plasma samples, followed …
Il-17 Drives Copper Uptake And Activation Of Growth Pathways In Colorectal Cancer Cells In A Steap4-Dependent Manner, Evan Martin
Il-17 Drives Copper Uptake And Activation Of Growth Pathways In Colorectal Cancer Cells In A Steap4-Dependent Manner, Evan Martin

Colorectal cancer is a disease characterized by abnormal, invasive cell growth beginning in the colon or rectum. The third most common type of cancer worldwide, approximately one million new cases of the disease are diagnosed across the globe annually, resulting in an estimated 700,000+ deaths. One major risk factor associated with development of colorectal cancer is the presence of chronic inflammation in the large intestine, also known as colitis. Inflammation is a complex immune response against harmful stimuli, characterized by symptoms including heat, redness, swelling and pain. One important molecular mediator of this process is interleukin 17 (IL-17), a pro-inflammatory …
