As the lipidomics field continues to advance, self-evaluation within the community is critical. Here, we performed an interlaboratory comparison exercise for lipidomics using Standard Reference Material (SRM) 1950-Metabolites in Frozen Human Plasma, a commercially available reference material. The interlaboratory study comprised 31 diverse laboratories, with each laboratory using a different lipidomics workflow. A total of 1,527 unique lipids were measured across all laboratories and consensus location estimates and associated uncertainties were determined for 339 of these lipids measured at the sum composition level by five or more participating laboratories. These evaluated lipids detected in SRM 1950 serve as community-wide benchmarks …

Structural And Functional Effect Of Phosphorylation On Ampa Receptors, Caitlin E. Nurik

Structural and Functional Effect of Phosphorylation on AMPA Receptors

Cailtin Edmunds show you, BA

Advisory Professor: Vasanthi Jayaraman, Ph. D.

The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor is the primary contributor to neuronal fast excitatory transmission, and plays a key role in learning and memory. Previous studies have established that residues S818, S831, and T840 in the C-terminal segment of GluA1 homomeric AMPA receptor are phosphorylated by PKC, and phosphorylation at these sites leads to an increase in receptor conductance. We show that the domain inclusive of those sites alters its secondary structure due to phosphorylation (using glutamate substitution as a mimic) …

The Role Of N-Myc Downstream Regulated Gene 1 In Breast Cancer Lipid Metabolism, Christopher James Sevinsky

Legacy Theses & Dissertations (2009 - 2024)

Altered carbohydrate and lipid metabolism are increasingly well characterized hallmarks of aggressive breast cancers. While aerobic glycolysis, or “the Warburg effect”, is a well-established metabolic adaptation exploited by tumor cells, the understanding of unique aspects of cancer lipid metabolism lags behind. This is especially true regarding the coordination of complex lipid synthesis and trafficking pathways, which remains poorly understood. N-Myc Downstream Regulated Gene1 (NDRG1) is overexpressed in many solid tumors, but its function is unclear. The importance of NDRG1 is best exemplified by the effect of null mutations on human physiology: inactivating mutations give rise to the severe autosomal recessive …
