The link between gut & brain health is a target of interest for Parkinson’s disease (PD) research. In this paper, Gordevicius et al, use multi-molecular methods to study PD pathology from epigenetic changes in DNA & altered transcription, to the resulting modified protein abundance.
Studies about cardiovascular diseases have shown the Elabela/Toddler (ELA) ligand to be a beneficial apelin Rc. agonist. In a recent paper, Nyimanu et al. used LC-MS/MS methods to examine how the different forms of ELA individually impact signaling networks in the human body.
In our food and supplements, we see new functional foods and nutraceuticals with new claims everyday. But do these compounds show any bioactivity to support these claims? Huang et al show Mass spec can be a great tool to study these compound.
In this study, Noori et al show that MS-based MRD monitoring is over 15-fold more sensitive than conventional diagnostic measures. More importantly, MS-based MRD monitoring with PEAKS de novo sequencing can be used with heterogeneous patient populations, and does not have to be adapted when novel t-mAb are approved for use in patients.
