Figure 3. Heatmap of Differentially Expressed Genes Between Control and Ri-PNS Breast Cancers.

Heatmap of differentially expressed genes (in rows) between Ri-PNS BC (green) and control luminal B BC (light blue) samples (in columns). Tumor sites are separated in primary BCs (PBT, purple) and metastatic lymph nodes (LN, pink). Clinical features of Ri-PNS are categorized into cerebellar (gray) or extracerebellar (yellow). TPM expression values were first transformed into log₁₀(TPM + 0.01) and then transformed into a Z-score per gene. BC = breast cancer; PBT = primary breast tumor; PNS = paraneoplastic neurologic syndrome; TPM = transcripts per million.
