Complementation of major histocompatibility haplotypes in regression of Rous sarcoma virus-induced tumors in noninbred chickens. 1982

D W Brown, and W M Collins, and P H Ward, and W E Briles

Relative responses to Rous sarcoma virus (RSV)-induced tumors were studied in UNH 105 chickens, a noninbred line of New Hampshires. A total of 799 chickens blood typed for B alloantigens were classified into six genotypes: B23/B23, B24/B24, B26/B26, B23/B24, B23/B26, and B24/B26. Chickens were inoculated with subgroup A Rous sarcoma virus in the left wingweb at 6 weeks of age. The in vivo response was evaluated and given a tumor profile index (TPI) based on the change in tumor size over a 10-week period postinoculation. The TPI's ranged from 1 (regressor) to 3 (progressor). The mean TPI of B23/B26 hosts (1.7) was significantly smaller than that of all other genotypes studied. The mean TPI's of the homozygous genotypes B23/B23, B26/B26, and B24/B24, were 2.0, 2.3, and 2.9, respectively, and differed significantly in all comparisons. These results suggest complementation of haplotypes influencing the anti-Rous sarcoma response.

UI MeSH Term Description Entries
D007519 Isoantigens Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. Alloantigens,Alloantigen,Isoantigen
D008285 Major Histocompatibility Complex The genetic region which contains the loci of genes which determine the structure of the serologically defined (SD) and lymphocyte-defined (LD) TRANSPLANTATION ANTIGENS, genes which control the structure of the IMMUNE RESPONSE-ASSOCIATED ANTIGENS, HUMAN; the IMMUNE RESPONSE GENES which control the ability of an animal to respond immunologically to antigenic stimuli, and genes which determine the structure and/or level of the first four components of complement. Histocompatibility Complex,Complex, Histocompatibility,Complex, Major Histocompatibility,Complices, Histocompatibility,Complices, Major Histocompatibility,Histocompatibility Complex, Major,Histocompatibility Complices,Histocompatibility Complices, Major,Major Histocompatibility Complices
D009365 Neoplasm Regression, Spontaneous Disappearance of a neoplasm or neoplastic state without the intervention of therapy. Neoplasm Remission, Spontaneous,Remission, Spontaneous Neoplasm,Regression, Spontaneous Neoplasm,Spontaneous Neoplasm Regression,Spontaneous Neoplasm Remission
D002645 Chickens Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA. Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D005816 Genetic Complementation Test A test used to determine whether or not complementation (compensation in the form of dominance) will occur in a cell with a given mutant phenotype when another mutant genome, encoding the same mutant phenotype, is introduced into that cell. Allelism Test,Cis Test,Cis-Trans Test,Complementation Test,Trans Test,Allelism Tests,Cis Tests,Cis Trans Test,Cis-Trans Tests,Complementation Test, Genetic,Complementation Tests,Complementation Tests, Genetic,Genetic Complementation Tests,Trans Tests
D006238 Haploidy The chromosomal constitution of cells, in which each type of CHROMOSOME is represented once. Symbol: N. Haploid,Haploid Cell,Cell, Haploid,Cells, Haploid,Haploid Cells,Haploidies,Haploids
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001357 Sarcoma, Avian Connective tissue tumors, affecting primarily fowl, that are usually caused by avian sarcoma viruses. Avian Sarcoma,Rous Sarcoma,Sarcoma, Rous,Avian Sarcomas,Sarcomas, Avian
