  • Title: Oncogene involvement in lymphoid malignancy.
    Author: Ngan BY, Berinstein N.
    Journal: Tumour Biol; 1990; 11 Suppl 1():78-93. PubMed ID: 2247757.
    Abstract:
    Several nonrandom chromosomal translocations that occur in T and B cell malignancy have been shown to involve the juxtaposition of a putative proto-oncogene and one of the antigen receptor genes. Cloning studies of several of these breakpoints have helped to elucidate the structural basis of some of these chromosomal translocations as well as the molecular characteristics of some of the proto-oncogenes. One of the most studied proto-oncogenes is BCL2, frequently involved in a translocation in B cell lymphomas. Several biological studies of the expression of this proto-oncogene in cell lines and/or transgenic mice have shown that it is one of the factors which can induce lymphoid proliferation and may thus be an important etiologic factor in the generation of B cell lymphoma. Cloning studies of these chromosomal breakpoints have led to the application of molecular genetic techniques for the diagnosis and detection of expression of these proto-oncogenes. Further study of these oncogenes is required to establish their role in tumorigenesis and their usefulness in clinical practice.
