Expression of PRR11, UCHL1, SNAT1, and EGR1 was also found to positively correlate in most other types of cancer (Figure 6B and 6C) Moreover, SNAT1 and EGR1 expression was significantly associated with regional lymph node metastasis, and a trend was observed between UCHL1 expression and lymph node metastases (Table S3, p = 0.078). Here, SLC38A1 is linked to cancer.
