Inhibitors against the kinase BRAF are initially effective against BRAFV600E mutant melanoma.Resistance inevitably develops,in part,because the cancer cells induce tumor-associated fibroblasts to produce stiff extracellular matrix that triggers adaptive signaling in the tumor cells (see also Zanconato and Piccolo).YAP and TAZ (collectively YAP/TAZ) are transcriptional regulators that Actomyosin contractility confers mechanoprotection against TNF-induced disruption of the intervertebral disc.Inflammation triggers degradation of intervertebral disc extracellular matrix (ECM),a hallmark of disc degeneration that contributes to back pain.Author:Paula A.Hernandez,Timothy D.Jacobsen,Nadeen O.ChahineCited by:2Publish Year:2020Actomyosin contractility confers mechanoprotection against Was this helpful?Actomyosin contractility confers mechanoprotection against Actomyosin contractility confers mechanoprotection against TNF-induced disruption of the intervertebral disc.Inflammation triggers degradation of intervertebral disc extracellular matrix (ECM),a hallmark of disc degeneration that contributes to back pain.Mechanosensitive nucleus pulposus cells are responsible for ECM production,yet the impact of a proinflammatory microenvironment on cell
