However, TNBC, HER2-enriched and luminal B cancers additionally included exocyst-associated markers (EXOC3, EXOC4, EXOC6B, EXOC7, and EXOC8), which suggested that, unlike luminal A, these cancers not only share dysregulation of ciliogenesis but also dysfunction of transport to cilium. Here, EXOC7 is linked to cancer.
