Sleep intensity is adjusted by the length of previous awake time, and under tight homeostatic control by protein phosphorylation. Here, we establish microglia as a new cellular component of the sleep homeostasis circuit. Using quantitative phosphoproteomics of the mouse frontal cortex, we demonstrate that microglia-specific deletion of TNFα perturbs thousands of phosphorylation sites during the sleep period.

Article Synopsis
  • The extracellular matrix (ECM) is crucial for physiological functions, varying by tissue type and influencing cell behavior, particularly in dental pulp stem cells (DPSCs).
  • This study focused on identifying ECM proteins from DPSCs and their effects on mineralization in human gingival fibroblasts (GF), which typically don't mineralize on their own.
  • Results showed that ECM from both normal and osteogenic conditions allowed GF to attach and grow, with osteogenic ECM promoting greater mineralization, indicating potential applications for tissue engineering in bone-related therapies.

RNF111/Arkadia is an E3 ubiquitin ligase that activates the transforming growth factor-β (TGF-β) pathway by degrading transcriptional repressors SKIL/SnoN and SKI. Truncations of the RING C-terminal domain of RNF111 that abolish its E3 function and subsequently activate TGF-β signaling are observed in some cancers. In the present study, we sought to perform a comprehensive analysis of RNF111 endogenous substrates upon TGF-β signaling activation using an integrative proteomic approach.
