Design And Synthesis Of Circadian Clock Modulators And The Study Of Lov Domain Protein Lkp2 In Arabidosis Thaliana And Brassica Rapa, Aditi Nagar
Chemistry Theses and Dissertations
Circadian rhythms are self-autonomous endogenous clocks synchronized with the rotation of the Earth. With the Earth’s rotation and revolution on its axis, the internal clock undergoes oscillation in the period of ~24 hour and governs day to day activities in most organisms. In humans, it regulates the day to day physiological activities. Today’s modern lifestyle has an impact on health: shift work, jet lag, and irregular eating habits contribute to the misalignment of the endogenous circadian oscillator, thereby, increasing the risk of many metabolic disorders including diabetes, irregular blood pressure, sleep disorders, obesity, depression, and cancer. The primary goal 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 …

Selective nitrosylation of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) at Cys-247 affects gene regulation through the interferon-gamma (IFN- γ) activated inhibitor of translation (GAIT) complex. Oxidized low-density lipoprotein (LDLox) and INF-γ induce assembly of the nitrosylase complex composed of inducible nitric oxide synthase (iNOS), S100A8, and S100A9 proteins. Crystal structure of the complex of GAPDH and S100A8A9 is not known, structural prediction method were employed by protein-protein docking and binding energy calculation with PatchDock and FIREDock respectively. Candidate models were selected, based on a weight factor calculated, from the computational method developed from the "artificial protease" cleavage mapping Fe(III) (s)-1-(p- …
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
ETD Archive
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 …

A Comprehensive Analysis Of Aromatic-Proton Mediated Hydrogen Bonds, Mona S. Alshamrani
Electronic Theses and Dissertations
Hydrogen bonds play critical role in folding, structure and recognition of biological macromolecules (e.g., proteins, RNA, DNA). In addition to classical hydrogen bonds (e.g., ─OH---O=, ─OH---O─, ─NH---O─ etc.), structural analysis of protein and nucleic acids, almost a decade ago, showed that hydrogen bonds (e.g., CH---O) with hydrogen atoms on aliphatic carbon atoms (hereafter, aliphatic-protons) also play very important role in the structure and function of biomolecules. Even though, protons of aromatic ring systems (hereafter, aromatic-protons) are more polar than the aliphatic-protons, systematic analysis of hydrogen bonds of aromatic-protons have not been carried out. Therefore, I carried out a systematic analysis …
