    Inhibition of Aberrant Tissue Remodeling by Mesenchymal Stromal Cells Singly Coated with Soft Gels Presenting Defined Chemomechanical Cues

    The authors showed that MSCs singly coated with a soft conformal gel presenting defined chemomechanical cues promoted matrix remodeling by secreting soluble interstitial collagenases in response to the presence of tumor necrosis factor-alpha.

    SPOP and OTUD7A Control EWS-FLI1 Protein Stability to Govern Ewing Sarcoma Growth

    Speckle-type POZ protein (SPOP) and OTU domain-containing protein 7A (OTUD7A) were identified as the bona fide E3 ligase and deubiquitinase, respectively, that control Ewing sarcoma breakpoint region 1-Friend leukemia integration 1 (EWS–FLI1) protein turnover in Ewing sarcoma.
