Therefore, ASB4 is a tumor-associated antigen that can elicit CTL responses specific to CSCs and can discriminate between two cellular subsets of colorectal cancer.
Adoptively transferred CTLs specific for the CSC antigen ASB4 could infiltrate implanted colorectal cancer cell tumors and effectively prevented tumor growth in a mouse model.
Of these, three genes (CYP11B2, MC2R, and HPX) may be related to aldosterone production, and five genes (PRRX1, RAB38, FAP, GCNT2, and ASB4) are potentially involved in tumorigenesis.
