In 2015, Pereira and colleagues demonstrated the aberrant expression of B lymphoid-lineage antigen CD37, a transmembrane protein of the tetraspanin superfamily, in 15 different AML cell lines, 5 of those AMoL, and confirmed it in a cohort of 26 patients'-derived AML samples (67). The gene discussed is CD37; the disease is acute myeloid leukemia.
