• YAP-mediated mechanotransduction determines the podocytes response to damage

  11-04-2017 19:55 via stke.sciencemag.org
  Podocytes are terminally differentiated cells of the kidney filtration barrier. They are subjected to physiological filtration pressure and considerable mechanical strain, which can be further increased in various kidney diseases. When injury causes cytoskeletal reorganization and morphological alterations of these cells, the filtration barrier may become compromised and allow proteins to leak into the urine (a condition called proteinuria). Using time-resolved proteomics, we showed that podocyt

• The transcription factor MAFK induces EMT and malignant progression of triple-negative breast cancer cells through its target GPNMB

  11-04-2017 19:55 via stke.sciencemag.org
  Triple-negative breast cancer (TNBC) is particularly aggressive and difficult to treat. For example, the transforming growth factor–β (TGF-β) pathway is implicated in TNBC progression and metastasis, but its opposing role in tumor suppression in healthy tissues and early-stage lesions makes it a challenging target. Therefore, additional molecular characterization of TNBC may lead to improved patient prognosis by informing the development and optimum use of targeted therapies. We

• Genomics and evolution of protein phosphatases

  11-04-2017 19:55 via stke.sciencemag.org
  Protein phosphatases are the essential opposite to protein kinases; together, these enzymes regulate all protein phosphorylation and most cellular processes. To better understand the global roles of protein phosphorylation, we cataloged the human protein phosphatome, composed of 189 known and predicted human protein phosphatase genes. We also identified 79 protein phosphatase pseudogenes or retrogenes, some of which may have residual function. We traced the origin and diversity of phosphatases b
