Scientists Find Gene Variant Giving Up to 70% Protection Against Alzheimer's

A newly discovered variant in the FN1 gene, which is responsible for making the fibronectin protein, reduces the likelihood of developing Alzheimer's by up to 70 percent.

New #mechanobiology paper on #cancer #microenvironment. The authors show that cancer-associated #fibroblasts (CAFs) compress tumors with actomyosin supracellular contractility supported by #fibronectin deposition. This induces #YAP nuclear exit in cancer cells, limits cancer growth, and induces tumor reorganization.

Cancer-associated fibroblasts actively compress cancer cells and modulate mechanotransduction - Nature Communications

Cancer-associated fibroblasts (CAFs) can produce ECM and form a physical barrier around the tumour. Here, the authors show in transgenic mouse models and in vitro systems that CAFs are able to actively compress cancer cells using actomyosin contractility and this leads to a modulation of cancer cell mechanosensing and tumour reorganisation.
