The carrier proteome limit should be reassessed for each mass analyzer architecture

The study shows that carrier proteome limits vary with mass analyzer type, suggesting that using analyzers with higher linear dynamic range can improve isobaric peptide signal amplification.

Single cell proteomics by mass spectrometry reveals deep epigenetic insight into the actions of an orphan histone deacetylase inhibitor

This study uses single cell proteomics by mass spectrometry to analyze histone post-translational modifications in cancer cells treated with an HDAC inhibitor, identifying 16 PTMs and a previously uncharacterized drug response.

Metabolomic, proteomic and single cell proteomic analysis of cancer cells treated with the KRASG12D inhibitor MRTX1133

This study uses metabolomic, proteomic, and single-cell proteomic analyses to investigate the effects of MRTX1133 on KRASG12D mutant pancreatic cancer cells, revealing distinct drug response populations.

An integrated method for single cell proteomics with simultaneous measurements of intracellular drug concentration implicates new mechanisms for adaptation to KRASG12D inhibitors

This paper develops a method to measure intracellular drug concentrations and proteomic responses in single cells, revealing drug response heterogeneity in KRASG12D inhibitor treatment.
