TOP STORYUsing patient samples and atomic force microscopy, scientists found that tissue stiffness was higher in liver metastases than in primary colorectal tumors. Highly activated metastasis-associated fibroblasts increased tissue stiffness, which enhanced angiogenesis and anti-angiogenic therapy resistance. [Cancer Cell] Full Article | Graphical Abstract | |

PUBLICATIONS(Ranked by impact factor of the journal)Polyethylene glycol-based immune organoids were developed to elucidate the effects of polymer end-point chemistry, integrin ligands, and mode of K. pneumoniae antigen presentation on germinal center-like B cell phenotype and epigenetics, to better define the lymph node microenvironment factors regulating ex vivo germinal center dynamics. [Adv Funct Mater] Abstract Investigators found a significant association between T cell infiltration in the bone marrow microenvironment of newly diagnosed patients with acute myeloid leukemia (AML) and increased overall survival. Functional studies aimed at establishing the degree of T cell suppression in patients with AML revealed impaired T cell function in many patients. [Proc Natl Acad Sci USA] Full Article Vascularized Silk Electrospun Fiber for Promoting Oral Mucosa Regeneration To endow the fiber with the function of promoting angiogenesis and oral mucosa regeneration, surface-aminated liposomes encapsulating leptin, as well as silk fiber membranes that had been immersed overnight in polydopamine solution were synthesized. [NPG Asia Mater] Full Article The authors stimulated cells and infected mice with M and FbaA mutants of M1 Group A Streptococcus strain SF370 or with purified M and FbaA proteins, and found that only FbaA protein was involved in autophagy induction. [MBio] Abstract Lack of Collagen XVIII Leads to Lipodystrophy and Perturbs Hepatic Glucose and Lipid Homeostasis Researchers observed that, in the high caloric diet, the overall adiposity was decreased by 30%, serum triglyceride values were three-fold higher and the steatotic area in liver was two-fold larger in the collagen XVIII knockout mice compared with the controls. [J Physiol] Abstract The authors tested whether the selectivity of [-1A]TIMP3 was beneficial compared with that of the wild-type TIMP3 in preventing or delaying the onset of the degenerative effects in a mouse model of osteoarthritis. They generated transgenic mice that overexpressed TIMP3 or [-1A]TIMP3 driven by a chondrocyte-specific type II collagen promoter. [Sci Rep] Full Article Based on the TCGA database, scientists defined specific, altered genes associated with different tumor immune microenvironment types, which might represent new predictive markers or targets for immuno-therapeutic approaches. [Sci Rep] Full Article Molecular docking studies on anthranoid, flavonoid, tannin and naphthalene skeletons with matrix metalloproteinase enzymes were applied for the first time. Various chromatographic methods were used for isolation studies. [Phytochem Anal] Abstract Measurement of extracellular matrix metalloproteinase-9 (MMP-9) level was performed using the InflammaDry test. The ocular surface disease parameters and MMP-9 expression levels were compared between the primary open-angle glaucoma group and the control group.

REVIEWSMaterials Design for Bone-Tissue Engineering The authors provide an overview of materials-design considerations for bone-tissue-engineering applications in both disease modeling and treatment of injuries and disease in humans. [Nat Rev Mater] Abstract The Tumor Microenvironment in Cholangiocarcinoma Progression Investigators summarize current understandings of the tumor microenvironment and intercellular communications in cholangiocarcinoma and their role in tumor progression. [Hepatology] Abstract Targeting Focal Adhesion Kinase in Cancer Cells and the Tumor Microenvironment Scientists discuss the role of nuclear focal adhesion kinase (FAK) as a driver for tumor cell survival as well as potential therapeutic strategies to target FAK in both tumors and the tumor microenvironment.
