The inactivation or loss of tumor suppressor genes (anti-oncogenes) has been implicated as a mechanism central to the pathogenesis of many solid tumors. More recently, we and others have identified a role of one rumor suppressor gene, the retinoblastoma gene, in the development of human lymphoid lymphoma and leukemia. Here we review the involvement of the retinoblastoma gene in the control of normal lymphocyte cell division and the consequences of inactivation of the retinoblastoma gene for the development of lymphoid neoplasia. Our survey has disclosed a broad involvement of retinoblastoma gene inactivation in a wide variety of non-Hodgkin's lymphomas and lymphocytic leukemia. Based on these early findings, it appears likely that tumor suppressor genes may well be involved in many hematopoietic neoplasma.

UI MeSH Term Description Entries
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006) Leucocythaemia,Leucocythemia,Leucocythaemias,Leucocythemias,Leukemias
D008223 Lymphoma A general term for various neoplastic diseases of the lymphoid tissue. Germinoblastoma,Lymphoma, Malignant,Reticulolymphosarcoma,Sarcoma, Germinoblastic,Germinoblastic Sarcoma,Germinoblastic Sarcomas,Germinoblastomas,Lymphomas,Lymphomas, Malignant,Malignant Lymphoma,Malignant Lymphomas,Reticulolymphosarcomas,Sarcomas, Germinoblastic
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D016161 Genes, Retinoblastoma Tumor suppressor genes located on human chromosome 13 in the region 13q14 and coding for a family of phosphoproteins with molecular weights ranging from 104 kDa to 115 kDa. One copy of the wild-type Rb gene is necessary for normal retinal development. Loss or inactivation of both alleles at this locus results in retinoblastoma.
