Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026Why does this matter in vivo? Using a synergist ablation overload, we show that tendon maladaptation develops over time. Genetic inhibition of HIF1α in tendon fibroblasts preserves tendon structure and mechanics. This supports HIF1α-regulated pathways as potential therapeutic entry point. (7/8) 110
Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026But, what triggers HIF1α? Mechanical overload. In vitro, tendon fibroblasts show a strain-dependent increase in HIF1α activation. Ex vivo, HIF1α activation emerges only once loading exceeds a damage threshold, indicating damage-associated activation, even under normal oxygen conditions. (6/8) 100
Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026By genetically decoupling vascular recruitment from HIF1α activation (via VEGFA-dependent mechanisms), we show that tendon degeneration occurs independently of angiogenesis, while vascular invasion is tightly coupled to myelinated nerve ingrowth.

Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026To investigate causality, we generated a tendon fibroblast–specific mouse model with chronic HIF1α activation. HIF1α activation alone was sufficient to drive ECM disorganization, mechanical dysfunction, hypercellularity, and neurovascular ingrowth, hallmark features of human tendinopathy. (4/8) 100
Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026Quantitative proteomics further uncovered pathological collagen remodeling, including increased pyridinoline (↑ PYD) crosslinking and altered collagen composition, helping explain why tendinopathic tendons become mechanically compromised. (3/8) 100
Laboratory of Exercise and Health - ETH Zürich @debocklab.bsky.social · 07/01/2026We started with clinical observations. Analyzing human tendinopathic samples, we asked which molecular pathways are altered in disease. Using immunofluorescence and integrative omics, we found strong enrichment of HIF1α signaling in both diseased long head of biceps and rotator cuff tear tendons. 110
