Integrin‐Piezo1 Axis Drives ECM Remodeling and Invasion of 3D Breast Epithelium Mechanical stiffening of the extracellular matrix around mature mammary acini induces sequential remodeling phases. An early response disrupts the basement membrane and promotes fibronectin secretion...

🚨Excited to share our new paper where we find that in situ ECM stiffening of mature mammary acini induces BM loss, FN deposition & invasion through α3β1/α5β1–FAK→Piezo1 axis—linking integrin switching to MSCs and epithelial remodelling. Led by the amazing Kabilan Sakthivel

Colorado CDC researcher terminated amid federal budget cuts while working on Lyme disease projects Colorado research biologist Joe Cardiello was excited about being involved in what could become lifesaving research for people who have been impacted by Lyme disease.

So many heartbreaking stories right now coming from the US. Joe was a post-doc fellow here at WCMM Lund University and moved back to Fort Collins for family and career.

Amazing and beautiful work as usual from @alushinlab.bsky.social

This work has led us now into a whole range of new projects and collaborations that we are very excited about. This project was a collaboration with the groups of Adam Simonsen at SDU, Cathy Merry and Amanda Wright at Nottingham and Pontus Nordenfelt

This work was inspired and stands on the shoulder of amazing work from several labs that have been developing alginate based hydrogel system and/or have been working on ECM stiffness-mechanotransduction pathways in epithelial structures for decades

Mechanistically, using antibodies, inhibitors etc, Kabilan found that this process of in-situ stiffening induced ECM remodelling and invasion of normal mammary acini was driven by beta1 integrin-FAK-Piezo1 pathway with Piezo1 specifically being downstream of integrin activation and signalling.

Kabilan then followed the process of in-situ stiffening induced changes in acini morphology and ECM properties over time and found interesting and "dynamic" changes in relative ECM enrichment which coincided with different stages of growth and the onset of invasion

Interestingly, he found several differences in basement membrane and ECM(Fibronectin) enrichment and organisation between acini embedded in in-situ stiffened gels compared to acini formed from single MCF10A cells embedded in stiff gels from Day 1 (see below)

Here Kabilan first embedded single MCF10A cells in a soft interpenetrating network hydrogel system and allowed it to form a normal mammary acini with its own native ECM environment. He then in-situ stiffened these gels thus mimicking tumour growth and invasion on normal 3D structures-

β1 Integrin–FAK–Piezo1 signalling axis drives in-situ stiffening mediated ECM remodelling and invasion of 3D breast epithelium Stiffening of tissue is a hallmark of cancer progression, driving invasive phenotypes through complex interactions between cells and their extracellular matrix (ECM). However, the mechanisms linking m...

I am very excited to (delayed) share our preprint which has been led by Kabilan Sakthivel on mechanisms by which ECM stiffening of normal 3D tissues in their native environment drives invasive phenotypes
