Differentially expressed proteins between FF/HOM and OCT/LMD samples. a–c FF/HOM vs. OCT/LMD-T and d–f, FF/HOM vs. OCT/LMD-TS. a, d Volcano plots showing the distribution of fold changes of protein abundance and adjusted p-value (BH) for each comparison. NS, not significant, here indicating adj. p-value ≥ 0.05 and |log₂ FC|≤ 1. b, e PCA analysis of 216 and 171 significant proteins, respectively. c, f Heat maps generated using unsupervised clustering analysis with 216 and 171 significant proteins, respectively. Each column represents one sample, each row represents a significant protein. LA, luminal A; LB1, luminal B1
