CCN1 and cancer: To explore the signaling molecules downstream of the YAP signaling involving PA‐potentiated metastasis, we analyzed our RNA‐seq data of PA‐ and BSA‐treated TOV‐112D cells, and the Heatmap showed the differential expression of signaling molecules involved in cancer metastasis such as LIMD1, CTGF, TGFB2, CYR61, ITGAV, FAT4, ODC1 (Figure S4F, Supporting Information).
