In a second screen of another set of 4 CRC cell lines (Colo-320, Caco-2, LS-180, and HT-29), also by flow cytometry, we verified that 2 of 4 expressed the Siglec-XII protein (LS-180 and HT-29) (Supplemental Figure 1A; supplemental material available online with this article; https://doi.org/10.1172/jci.insight.181539DS1). Here, SIGLEC12 is linked to colorectal carcinoma.
