ProteomicsThe heat shock response in yeast is modular and maintains protein homeostasis via distinct mechanisms
We globally analyzed the heat stress response (HSR) in yeast on the transcriptomic, tranlatomic and the proteomic level. The cells were stressed at 37 °C, 42 °C and 46 °C and the fractionated proteomes measured on a Fusion and Q-Exactive Plus (both Thermo) mass spectrometer, respectively. With this ...

MetabolomicsGut Microbiota-Derived Indole-3-Propionic Acid Ameliorates Diabetic Cardiomyopathy by Regulating Mitochondrial Dynamics via the AhR/Nrf2 Pathway
This study investigated serum metabolic alterations in a mouse model of diabetic cardiomyopathy and evaluated the protective role of the gut microbiota-derived metabolite indole-3-propionic acid. Serum samples from mice were analyzed using untargeted LC-MS metabolomics. The study focused on the rela...

MetabolomicsAttenuate host susceptibility to respiratory virus invasion by inhibiting interactions between host proteins SLC16A3 and AP1G1

Modulating cell endocytosis activity to reduce host susceptibility to virus represents a promising strategy for antiviral drug development. In this study, we reveal that lactate transporter SLC16A3 as a critical host factor for reducing diverse virus invasion. By performing metabolomics, proteomi...

ProteomicsFlexible B12 ecophysiology of Phaeocystis antarctica due to a B12-independent methionine synthase fusion protein with widespread homologues
Coastal Antarctic marine ecosystems play an important role in carbon cycling due to their highly productive seasonal phytoplankton blooms. Southern Ocean microbes are primarily limited by light and iron (Fe) and can be co-limited by cobalamin (vitamin B12 ). Micronutrient limitation is a key driver ...
