abstract = {Interest in the role of bis(monoacylglycero)phosphate (BMP)
lipids in lysosomal function has significantly grown in
recent years. Emerging evidence highlights BMPs as critical
players not only in Niemann-Pick disease type C (NPC) but
also in other pathologies such as neurodegeneration,
cardiovascular diseases, and cancers. However, the selective
analysis of BMPs is significantly hindered by isomeric
phosphatidylglycerol (PG) lipids. While this can be
addressed by chromatographic separation, it poses a
significant challenge for shotgun lipidomics approaches.
Here, we present a shotgun lipidomics strategy to detect and
separate BMPs from PGs using differential fragmentation of
sodiated ions. This approach, including isotope correction,
is integrated into an existing quantitative shotgun
lipidomics workflow (Lipidyzer combined with Shotgun
Lipidomics Assistant software) that simultaneously
quantifies >1400 lipids. Validation using K-562 cell
extracts demonstrated acceptable linearity, trueness,
repeatability, and a limit of quantification of 0.12 µM,
confirming robust analytical performance. Finally,
characteristic accumulation of BMP lipids is shown in bone
marrow-derived macrophages from NPC mice, demonstrating its
applicability. Our method presents a quantitative,
selective, rapid, and robust solution for shotgun-based BMP
analysis without the need for extensive chromatographic
separation or derivatization. The integration of BMP lipid
detection into the Lipidyzer platform, alongside the
recently launched iSODA data visualization tool, empowers
chemists and biologists to gain deeper insights into BMP
lipid biology.},
