SLC9A1 and colorectal neoplasm: In order to explore in detail the expression of the SLC9A1 gene in colon cancer we also used a single-cell RNA-seq dataset identified as “Single cell sequencing of colorectal tumors and adjacent non-malignant colon tissue” deposited in the EMBL-EBI Expression Atlas (www.ebi.ac.uk/gxa; accessed on 29 August 2022).
