Matrisome analysis of NSCLC unveils clinically-important cancer-associated extracellular matrix changes.

Introduction: Non-small cell lung carcinoma (NSCLC), comprising adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC), is characterized by an active desmoplastic stroma with an accumulation of extracellular matrix (ECM) proteins. ECM remodeling is a key feature of cancer progression, but the identification of specific therapeutic targets within this compartment remains challenging. Recent studies suggest a link between increased desmoplastic stroma and malignancy in NSCLC, the role of ECM proteins in disease pathogenesis remains unclear.
