Along the progression of one subtype of HPH, CTEPH, the target genes of hsa-miR-942-5p are predominantly enriched in cancer-related pathways, while the target genes of hsa-miR-940 are notably enriched in the ErbB signaling pathway, thereby signifying the importance of these pathways in CTEPH.15 Here, EGFR is linked to chronic thromboembolic pulmonary hypertension.
