Since HL-60 and U937 do not express CEACAM-5 or CEACAM-6, it is very likely that NEO-201 binds to different types of cancers expressing core 1 and/or extended core 1 O-glycans attached not only to the tumor-associated variant of CEACAM5 and CEACAM6 but also to other protein carriers [17]. The gene discussed is CEACAM6; the disease is neoplasm.
