Implication

Transcriptomic analysis uncovers a TPM1-positive myCAF gene signature in pancreatic cancer, suggesting its utility for predicting survival and therapy response.

Key Points

To identify key prognostic cell subtypes and construct a robust gene-signature risk model for pancreatic cancer using single-cell and bulk transcriptomic data.
Analyzed single-cell RNA sequencing data (GSE197177) and bulk RNA sequencing from TCGA-PAAD using BayesPrism and Cox regression to identify cell subtypes linked to prognosis.
Screened prognostic hub genes via high-dimensional weighted gene co-expression network analysis (hdWGCNA), differential expression analysis, and LASSO regression to build a risk score and nomogram.
Identified TPM1+ myofibroblastic cancer-associated fibroblasts (myCAFs) as the primary prognostic cell subtype and isolated six hub prognostic genes: AHNAK2, ARHGAP32, EVL, PRKCI, PTGES, and S100A16.
Determined that risk scores based on the six-gene signature correlated with cell cycle activation, T follicular helper cell infiltration, immune checkpoint blockade response, and lapatinib sensitivity.
