Nanodiscs: A Novel Approach To The Study Of The Methionine Abc Transporter System, Michael T. Winslow Aug 2023

Nanodiscs: A Novel Approach To The Study Of The Methionine Abc Transporter System, Michael T. Winslow

Master's Theses

Membrane transporter proteins play the vital role of moving compounds in and out of the cell and are essential for all living organisms. ATP Binding Cassette (ABC) family transporters function both as importers and exporters in prokaryotes. MetNI is an E. coli Type I ABC transporter responsible for the uptake of methionine into the cytosol from the cell periplasmic space through the cell membrane to maintain intracellular methionine pools. ABC transporters, like other membrane proteins, are most often mechanistically and structurally studied in vitro, solubilized by detergents. However, detergent micelles may affect the conformational changes of membrane proteins relative to …


The Effect Of All-Trans Retinoic Acid And Fatty Acids On Mcf-7 Breast Cancer Cell Progression, David A. Brown Oct 2009

The Effect Of All-Trans Retinoic Acid And Fatty Acids On Mcf-7 Breast Cancer Cell Progression, David A. Brown

Master's Theses

Vitamin A metabolites and retinoids may slow the progression of breast cancer and elicit anti-neoplastic properties similar to those of omega-3 fatty acids. Studies using animal models show a decrease in the incidence, growth and metastisis of mammary tumors in the presence of specific fatty acids. This effect is also seen with use of retinoids, specifically all-trans retinoic acid (AtRA). Thus, fatty acids may also alter retinoid homeostasis in mammary carcinoma cells (MCF-7s). The potential for inter/co dependency among fatty acids and retinoids is considerable, and here it has been hypothesized that a decrease in cancer progression will occur in …
