Decellularized Extracellular Matrix Scaffolds Identify Full-Length Collagen VI as a Driver of Breast Cancer Cell Invasion in Obesity and Metastasis

The authors describe a method to study whole-tissue extracellular matrix (ECM) effects from disease states associated with metastasis on tumor cell phenotypes and identified the individual ECM proteins and signaling pathways that were driving these effects. They showed that decellularized ECM from tumor-bearing and obese mammary glands drives TNBC cell invasion.

Siah2 Integrates Mitogenic and Extracellular Matrix Signals Linking Neuronal Progenitor Ciliogenesis with Germinal Zone Occupancy

Researchers determined that the Siah2 E3 ubiquitin ligase functions in a coincidence detection circuit linking responses to the Shh mitogen and the ECM to control cerebellar granule neurons germinal zone occupancy.

Modeling the Interaction between the Microenvironment and Tumor Cells in Brain Tumors

The authors focus on brain microenvironment features impacted by tumor biology. They also discuss limits of current preclinical models and how complementary models, such as humanized animals and organoids, will allow deeper mechanistic insights on cancer biology, allowing for more efficient testing of therapeutic strategies, including immunotherapy, for brain cancers.

ER-Resident Oxidoreductases Are Glycosylated and Trafficked to the Cell Surface to Promote Matrix Degradation by Tumor Cells

Investigators showed that GALA induced the glycosylation of the ER-resident calnexin (Cnx) in breast and liver cancer. Glycosylated Cnx and its partner ERp57 are trafficked to invadosomes, which are sites of ECM degradation.

Tenascin C Promotes Cancer Cell Plasticity in Mesenchymal Glioblastoma

Researchers identified Tenascin C (TNC) to be upregulated and secreted in mesenchymal glioblastoma subtype with high NF-κB signaling activity. Silencing TNC decreased proliferation, migration and suppresses self-renewal of glioma stem cells.

Matrix Pore Size Governs Escape of Human Breast Cancer Cells from a Microtumor to an Empty Cavity

By varying the physical properties of collagen, investigators found that MDA-MB-231 tumor cells invaded and escaped faster in lower-density ECM. These effects were mediated by the ECM pore size, rather than by the elastic modulus or interstitial flow speed.
