Shangguan et al. [36] developed 6 Cell-SELEX-generated aptamers against neoplastic cells; among these aptamers, sgd5 recognized only its target Toledo cells, while sgc3, sgd2, sgd3, sgc4, and sgc8, selected from a T-cell acute leukemia (T-ALL) cell line CCRF-CEM cells, identified all of the cultured T-ALL cell lines. Here, SMARCD2 is linked to acute lymphoblastic leukemia.
