5T4 oncofetal antigen is expressed in high risk of relapse childhood pre-B acute lymphoblastic leukemia and is associated with a more invasive and chemotactic phenotype.
FLT3 transcripts were found in seven of seven pre B-ALL cell lines (derived from cases with pre B-acute lymphoblastic leukemia or chronic myeloid leukemia in lymphoid blast crisis), and in one of six B-cell lines (namely in a cell line established from a hairy cell leukemia).
CBFA2 forms a fusion gene with ETO and MDS1/EVI1 in translocations in myeloid leukemia and with ETV6(TEL) in the t(12;21) common in childhood pre-B acute lymphoblastic leukemia.
A common non-random translocation in childhood pre-B acute lymphoblastic leukemia (ALL) is t(1;19)(q23;p13), usually resulting in the expression of the chimeric gene E2A-PBX1.
A new E2A-PBX-1 fusion transcript positive t(1;19) pre-B ALL cell line (designated LC1;19) with the composite immunophenotype CD7-CD10+CD19+CD45-HLA-DR+C mu+ was established by expanding BM blasts from a SCID mouse, which died of human t(1;19) ALL at 7 weeks after inoculation of primary leukemic blasts from a t(1;19) ALL patient.

A new, lineage specific, autoup-regulation mechanism for human glucocorticoid receptor gene expression in 697 pre-B-acute lymphoblastic leukemia cells.
A well-characterized example of a potential tumor antigen in childhood pre-B Acute Lymphoblastic Leukemia (ALL) results from the chromosomal translocation 12;21 leading to the fusion of the ETV6 and AML1 genes.

Activation of PAX5 paralogs, PAX2 or PAX8, ordinarily silenced in lymphocytes, may therefore represent a novel approach for treating PAX5-deficient ALL.

Among them, the MLL/AFF1 (AF4/FMR2 family, member 1) fusion, associated with rearrangements between bands 4q21 and 11q23 is a recurrent event in pre-B acute lymphoblastic leukemia (ALL).
