Heterogeneity of the molecular lesions in inherited phosphofructokinase deficiency.
Human phosphofructokinase (PFK; EC 2.7.1.11) exists in tetrameric isozymic forms. Muscle and liver contain the homotetramers M4 and L4, whereas erythrocytes contain five isozymes composed of M (muscle) and L (liver) subunits, i.e., M4, M3L, M2L2, ML3, and L4. Inherited defects of erythrocyte PFK are usually partial and are described in association with heterogeneous clinical syndromes. To defin...
متن کاملMolecular Heterogeneity of Human
Interleukin 2 (IL-2,1 formerly termed T cell growth factor), discovered by Morgan et al. (1) is produced by T lymphocytes after antigen or mitogen stimulation and is required for the proliferation of activated T cells. IL-2 is an essential mediator o f the immune response (2, 3), and there is prel iminary evidence that it may also be responsible for the abnormal cell proliferation in h u m a n ...
متن کاملGenetic Heterogeneity of Benign Thyroid Lesions
The present series includes 75 thyroid lesions (38 goiters, 30 adenomas, 3 follicullo-papillary encapsulated carcinomas and 4 normal thyroid) that were studied by static and flow cytometry. Four cases were also analyzed by in situ hybridization (centromeric probes for chromosomes 1 and 17) and 10 cases by G-banding cytogenetics. Results demonstrate a polymorphysm and genetic instability in the ...
متن کاملHeterogeneity of expression and induction of mouse mammary tumor virus antigens in mouse mammary tumors.
Seven spontaneous BALB/cfC3H mouse mammary tumors were heterogeneous in expression of murine mammary tumor virus-associated cell surface antigens. To determine the basis of this heterogeneity, cells from spontaneous tumors and from five subpopulations isolated from a single spontaneous tumor were examined for expression of viral antigens under both conventional conditions and conditions known t...
متن کاملMolecular heterogeneity of adherens junctions
We describe here the subcellular distributions of three junctional proteins in different adherens-type contacts. The proteins examined include vinculin, talin, and a recently described 135-kD protein (Volk, T., and B. Geiger, 1984, EMBO (Eur. Mol. Biol. Organ.) J., 10:2249-2260). Immunofluorescent localization of the three proteins indicated that while vinculin was ubiquitously present in all a...
