Summary
This study reveals an unexpected non-catalytic function of the receptor tyrosine kinase ROR1 in sustaining cellular caveolae and survival signalling in lung adenocarcinoma. By acting as a molecular scaffold bringing cavin-1 and caveolin-1 together at the plasma membrane, ROR1 prevents CAV1 degradation and maintains signalling through multiple receptor tyrosine kinases to AKT. The findings suggest that blocking ROR1's scaffolding function may overcome EGFR-TKI resistance in lung cancer by preventing bypass signalling through alternative RTKs.
UK applicability
This basic mechanistic research on lung cancer cell signalling is internationally applicable but does not directly address UK farming systems, soil health, or primary food production. Its relevance to the Vitagri Pulse Brain catalogue is limited unless connected to broader nutritional or food-system outcomes in future translational work.
Key measures
ROR1 scaffolding interactions with cavin-1 and CAV1; caveolae structure integrity; CAV1 protein stability; AKT phosphorylation; RTK-mediated survival signalling (EGFR, MET, IGF-1R pathways)
Outcomes reported
The study identified a kinase-independent scaffolding function of ROR1 that facilitates cavin-1 and caveolin-1 interactions at the plasma membrane, preventing CAV1 lysosomal degradation and sustaining caveolae structures and AKT-mediated prosurvival signalling.
