NOTCH1 and lung cancer: The enrichment results illustrated that processes related to poor survival in lung cancer patients, cancer microenvironment, immature B lymphocytes, early T lymphocytes and lung metastasis were significantly enriched in the high-risk group (Figure 7D), while processes related to COMP, lectin, TCRA, NOTCH1 target and hypoxia were significantly enriched in the low-risk group (Figure 7E).
