TOP STORYTranscytosis of Nanomedicine for Tumor Penetration Scientists demonstrated that nanomedicine penetrated tumor lesions via an active trans-cell transportation process. They also demonstrated that enhanced tumor penetration promoted the therapeutic efficacy of a photodynamic therapeutic nanomedicine. [Nano Lett] Abstract | |

PUBLICATIONS(Ranked by impact factor of the journal)Researchers report on the design of a constitutional dynamic networks consisting of four toehold-modified constituents, two of which acted as bidentate units for chain-elongating, while the other two formed a tetradentate structure acting as a crosslinking unit. [Nat Commun] Full Article Macrophage Metabolic Reprogramming Aggravates Aortic Dissection through the HIF1α-ADAM17 Pathway Mechanistic studies revealed that macrophage hypoxia-inducible factor 1-alpha (HIF-1α) activation triggered vascular inflammation, ECM degradation and elastic plate breakage through increased a disintegrin and metallopeptidase domain 17, identified as a novel target gene of HIF-1α. [EBioMedicine] Full Article The expression of ADAM8 was up-regulated in osteoarthritic chondrocytes. Knockdown of ADAM8 suppressed the osteoarthritis (OA) phenotype in the in vitro OA cell model. ADAM8 regulated OA progression through the activation of EGFR/ERK/NF-κB signaling pathway. [Cell Commun Signal] Full Article The authors characterized the ability of RGD-binding integrins to mediate cell adhesion to fibrillin-1 or a disease-causing variant. They showed that seven of the eight RGD-binding integrins could mediate adhesion to fibrillin-1. [J Biol Chem] Abstract | Full Article Investigators implemented a combined computational modeling and experimental approach to evaluate tumor growth following hepatic injury, focusing on ECM remodeling and interactions with local macrophages. Experiments were performed to determine ECM density and macrophage-associated cytokine levels. [Sci Rep] Full Article Researchers investigated the response of mice lacking TIMP-3 (TIMP-3-/-) to hepatic IRI. They report that TIMP-3-/- mice showed an enhanced inflammatory response, exacerbated organ damage, and further impaired liver function after IRI when compared to their wild-type littermates. [Liver Transpl] Abstract The Interplay Between Cell-Cell and Cell-Matrix Forces Regulates Cell Migration Dynamics Scientists developed an integrated experimental and analytical system to examine both the intercellular and extracellular traction forces acting on individual cells within an endothelial cell colony, as well as their roles in guiding cell migratory behaviors. [Biophys J] Abstract The underlying mechanisms of antioxidant effect of AB38b were explored in high glucose (HG)-treated mouse glomerular mesangial cells (GMCs). AB38b or resveratrol significantly alleviated oxidative stress and ECM accumulation in HG-treated GMCs.

REVIEWSMetalloproteases: On the Watch in the Hematopoietic Niche Metalloproteases and their inhibitors can impact the bioavailability of important local signals that instruct mammalian hematopoietic stem cell fate and function in the hematopoietic niche. Despite growing evidence, metalloprotease/tissue inhibitors of metalloproteases proteins are currently underappreciated as important modulators of hematopoiesis. [Trends Immunol] Full Article The authors summarize current knowledge regarding the established involvement of the laminin 332 γ2 chain in tumor invasiveness and discuss the role of its α3 and β3 subunits.

POLICY NEWSTrump Names Seven to Revived Presidential Science Advisory Panel Thirty-three months after taking office, President Donald Trump has chosen a group of business leaders to advise him on science and technology policy. [ScienceInsider] Editorial UK Science Minister Says DARPA-Like Agency Is in the Works The UK government is working to establish a “blue sky” funding agency similar to the US Defense Advanced Research Projects Agency, UK science minister Chris Skidmore told the Science and Technology Select Committee of Parliament’s House of Commons.
