Inflammatory responses are important in cancer, particularly the context of monocyte-rich aggressive myeloid neoplasm. We developed a label-free cellular phenotypic drug discovery assay to identify anti-inflammatory drugs human monocytes derived from acute leukemia (AML), by tracking several features ionizing only 2500 cells using matrix-assisted laser desorption/ionization-time flight (MALDI-TOF) mass spectrometry. A proof-of-concept screen showed that BCR-ABL inhibitor nilotinib, but not structurally similar imatinib, blocks inflammatory responses. In order (off-)targets we performed thermal proteome profiling (TPP). Unlike nilotinib and other later-generation inhibitors bind p38α inhibit p38α-MK2/3 signaling axis, which suppressed pro-inflammatory cytokine expression, cell adhesion, innate immunity markers activated AML. Thus, our study provides tool for new drugs, could contribute treatment inflammation neoplasms diseases.

Method development for mass spectrometry (MS)-based thermal shift proteomic assays have advanced to probe small molecules with known and unknown protein-ligand interaction mechanisms specificity, which is predominantly used in characterization of drug-protein interactions. In the discovery target off-target interactions, a thorough investigation method their impact on sensitivity accuracy protein-small molecule protein-protein interactions warranted. this review, we discuss areas improvement at each stage proteome profiling data analysis that includes processing MS-based data, development, effect overall quality profiles. We also overview optimization experimental strategies prioritization an increased number independent biological replicates over evaluated temperatures.

Although the use of detergents in thermal proteome profiling (TPP) has become a common practice to identify membrane protein targets complex biological samples, surprisingly, there is no proteome-wide investigation into impacts detergent introduction on target identification performance TPP. In this study, we assessed TPP presence commonly used non-ionic or zwitterionic using pan-kinase inhibitor staurosporine, our results showed that addition either these significantly impaired at optimal temperature for soluble identification. Further destabilized and increased precipitation. By lowering applied point, with improved comparable absence detergents. Our findings provide valuable insight how select appropriate range when are addition, also suggest combination heat may serve as novel precipitation-inducing force can be
