To explore the effect of MTA1 expression on colorectal cancer immune cell infiltration in the tumor microenvironment, we used the TIMER 2.0 (10) database to evaluate the correlation between the MTA1 expression level and immune cell infiltration score in the colorectal cancer cohort of the TCGA (The Cancer Genome Atlas, TCGA) database. Here, MTA1 is linked to colorectal cancer.
