To explore the role of CTHRC1 and TGFb crosstalk in driving tumor invasion in early-stage lung adenocarcinoma (LUAD).
Performed unsupervised clustering of 53 early-stage LUAD tumors.
Investigated fibroblast-tumor cell interactions using co-culture techniques and analyzed gene expression.
Utilized spatial analysis and scRNA sequencing from multiple LUAD datasets.
Identified four tumor subgroups associated with varying levels of invasiveness.
CTHRC1 expression was higher in invasive myofibroblast populations compared to non-invasive counterparts.
Myofibroblast exposure to tumor cell conditioned media increased invasion in LUAD cells, which was inhibited by blocking TGFb signaling.
