Synergistic Effect of Carfilzomib and Metformin in Vascular Plasticity; The Emerging Role of Autophagy
2019
Introduction: Carfilzomib (Cfz) correlates with a risk of reversible cardiotoxicity in 5-10% of multiple myeloma (MM) patients. We have recently shown that metformin (Met) has a prophylactic role against the Cfz-induced cardiotoxicity in vivo, through activation of AMPKα signaling (Blood 2019;133:710-23). However, the impact of Cfz on vascular function is obscure. Therefore, we sought to investigate: i) the acute, ii) the sub-chronic effect of Cfz on the vascular reactivity, iii) the effect of metformin co-administration on the vascular phenotype and iv) the impact of Cfz and Met co-administration on aged Human Aortic Smooth Muscle Cells (HAoSMCs). Methods: Forty male C57Bl/6 mice were assi…
Machine Learning Unveils Proteotypic Mimicry in Genetically Defined SCN Variants
2019
Background Novel computational algorithms for multi-omics analysis bear great potential to highlight pathomechanisms of monogenic diseases. We recently defined the in-depth proteome of primary human neutrophil granulocytes (PMID 30630937). Here, we ask the question whether proteotypic patterns differ between defined genetic subtypes associated with severe congenital neutropenia (SCN). We focus on two novel genetic variants in constituents of the signal recognition particle (SRPRA and SRP19) and previously reported SCN genotypes SRP54, HAX1, and ELANE. Methods We analyzed proteomes of highly purified neutrophil granulocytes from a total of 26 SCN patients, including 5 with homozygous splice …
