Comparative analysis of sucrose-embedding for whole-body zebrafish MSI by IR-MALDESI

Wang, M. F., Ritter, M. M., Kullman, S. W., & Muddiman, D. C. (2023, August 29). ANALYTICAL AND BIOANALYTICAL CHEMISTRY, Vol. 8.

By: M. Wang n, M. Ritter  n, S. Kullman n  & D. Muddiman n 

author keywords: IR-MALDESI; Mass spectrometry imaging; Sucrose; PFA; Zebrafish
TL;DR: Danio rerio, or zebrafish, are model organisms for various disease states and can be imaged as a multi-organ sample to analyze morphological and metabolomic preservation as a result of sample preparation to compare sucrose-embedding with paraformaldehyde fixation against conventional fresh-frozen sample preparation.

2023 article

Maximized Spatial Information and Minimized Acquisition Time of Top-Hat IR-MALDESI-MSI of Zebrafish Using Nested Regions of Interest (nROIs)

Joignant, A. N., Ritter, M. M., Knizner, K. T., Garrard, K. P., Kullman, S. W., & Muddiman, D. C. (2023, August 1). JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY, Vol. 8.

By: A. Joignant n, M. Ritter  n, K. Knizner n, K. Garrard n, S. Kullman n  & D. Muddiman n 

author keywords: IR-MALDESI; mass spectrometry imaging; spatialresolution; nested region of interest; zebrafish
TL;DR: The nROI method was characterized on mouse liver and applied to top-hat MSI of zebrafish using a novel optical train, which resulted in a significant improvement in both acquisition time and spatial detail of the zebra fish. (via Semantic Scholar)

Vitamin D deficiency promotes accumulation of bioactive lipids and increased endocannabinoid tone in zebrafish

JOURNAL OF LIPID RESEARCH, 62.

By: M. Knuth  n, W. Stutts n , M. Ritter  n, K. Garrard n & S. Kullman n 

author keywords: MS; metabolomics; lipidomics; lipids; nutrition; endocannabinoid biosynthesis; MSI; IR-MALDESI; anandamide
MeSH headings : Animals; Endocannabinoids / metabolism; Lipid Metabolism; Lipids / chemistry; Vitamin D Deficiency / metabolism; Zebrafish
TL;DR: Investigation of putative linkages between vitamin D deficiency and metabolic disruption of bioactive lipids by MS imaging and expression of genes involved in EC biosynthesis, metabolism, and receptor signaling in adipose tissue and liver suggest that VDD may promote accumulation of bio active lipids and increased EC tone in zebrafish.
