Conformational Dynamics Of Biomolecules By Trapped Ion Mobility Spectrometry Dynamics, Juan Camilo Molano-Arévalo
Conformational Dynamics Of Biomolecules By Trapped Ion Mobility Spectrometry Dynamics, Juan Camilo Molano-Arévalo
FIU Electronic Theses and Dissertations
One of the main goals in structural biology is to understand the folding mechanisms and three-dimensional structure of biomolecules. Many biomolecular systems adopt multiple structures as a function of their microenvironment, which makes them difficult to be characterized by traditional structural biology tools (e.g., NMR, X-ray crystallography). As an alternative, complementary tools that can capture and sample multiple conformations needed to be developed. In the present work, we pioneered the application of a new variant of ion mobility spectrometry, trapped ion mobility spectrometry (TIMS), which provides high mobility resolving power and the possibility to study kinetically trapped intermediates as a …

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 …

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 …
