ProteomicsBacterial Hsp90 mediates the degradation of aggregation-prone Hsp70-Hsp40 substrates preferentially by the HslUV protease
Whereas in eukaryotic cells Hsp90s are extensively studied in bacteria, the function of Hsp90 (HtpG) and its functional relationship with Hsp70 (DnaK) remains unknown. To uncover physiological processes depending on HtpG and DnaK, we performed comparative quantitative proteomic analyses of insoluble...

ProteomicsQuantitative proteomic analysis to capture the role of heat-accumulated proteins in moss plant acquired thermotolerance
At dawn of a scorching summer day, land plants must anticipate upcoming extreme midday temperatures by timely establishing molecular defenses that can maintain heat-labile membranes and proteins in a functional state. A gradual morning pre-exposure to increasing sub-damaging temperatures induces the...

ProteomicsQuantitative proteomics of heat-treated human cells show an across-the-board mild depletion of housekeeping proteins to massively accumulate few HSPs
We used here high-throughput quantitative proteomics and targeted mRNA quantification to estimate in human cell cultures the mass and copy numbers of the most abundant proteins that become significantly accumulated, depleted or unchanged during and following a 4h heat shock at 41C.

ProteomicsQuantitative proteomics of rat livers shows that unrestricted feeding and re-feeding after food restriction are stressful for cellular proteostasis
We used quantitative MS-based proteomic analysis of whole rat livers to study the molecular events associated with a food restriction regimen as compared with ad libitum food and animals re-fed after a restriction time.

TranscriptomicsPlasma Membrane Cyclic Nucleotide Gated Calcium Channels Control Land Plant Thermal Sensing and Acquired Thermotolerance
Analysis of transcriptome in moss Physcomitrella patens CNGCb null mutant at 25 and 34 degrees C for 30 minutes. Results provide insight into role of CNGCb in acquired thermotolerance induced by non-lethal heat treatment. Typically at dawn of a hot summer day, land plants need precise molecular th...
