Integrative Omics Reveals Glutamine Catabolism-Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading. [PDF]
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.

Ubiquitinomics: History, methods, and applications in basic research and drug discovery
Abstract The ubiquitin‐proteasome system (UPS) was discovered about 40 years ago and is known to regulate a multitude of cellular processes including protein homeostasis. Ubiquitylated proteins are recognized by downstream effectors, resulting in alterations of protein abundance, activity, or localization.

Integrative Proteomic Analysis of Multiple Posttranslational Modifications in Inflammatory Response
Posttranslational modifications (PTMs) of proteins, particularly acetylation, phosphorylation, and ubiquitination, play critical roles in the host innate immune response. PTMs’ dynamic changes and the crosstalk among them are complicated.

Ubiquitin proteomics identifies RNA polymerase I as a target of the Smc5/6 complex
Summary: Ubiquitination controls numerous cellular processes, and its deregulation is associated with many pathologies. The Nse1 subunit in the Smc5/6 complex contains a RING domain with ubiquitin E3 ligase activity and essential functions in genome ...

Comprehensive analysis of the ubiquitinome during oncogene-induced senescence in human fibroblasts [PDF]
Oncogene-induced senescence (OIS) is an important tumor suppression mechanism preventing uncontrolled proliferation in response to aberrant oncogenic signaling. The profound functional and morphological remodelling of the senescent cell involves extensive changes.

Mapping the functional importance of site-specific ubiquitination across the human proteome
Abstract Protein ubiquitination regulates cell biology through diverse avenues, from quality control-linked protein degradation to signaling functions such as modulating protein-protein interactions and enzyme activation. To date, hundreds of thousands of ubiquitination sites (ubi-sites) have been identified, however fewer than 1% have ...

Detection of the Ubiquitinome in Cells Undergoing Oncogene-Induced Senescence [PDF]
Senescent cells exhibit dramatic changes in protein post-translational modifications. Here, we describe a method, stable isotope labeling with amino acids in cell culture (SILAC) coupled to liquid chromatography tandem mass spectrometry (LC-MS/MS), to identify changes in the ubiquitinome in cells that have undergone oncogene-induced senescence.

Ubiquitous Ubiquitin: The K63 Ubiquitinome [PDF]
Polyubiquitination, the sequential attachment of the small 8 kDa globular protein ubiquitin (Ub) to target proteins, represents a major posttranslational modification that ultimately determines the substrate’s cellular fate. Ub conjugation is an extremely versatile form of protein regulation,
