Polyethylene glycol-1000 (PEG-1000) induced fusion of HPRT (E.C. 2.4.2.8) deficient Chinese hamster cells with alpha-galactosidase A (E.C. 2.3.1.22) deficient cells from a patient with Fabry's disease yielded hybrids which contained both human and hamster HPRT, G6PD (E.C. 1.1.1.49), and APRT (E.C. 2.4.2.7) and Chinese hamster alpha-galactosidase B. Thus PEG-1000 mediated somatic cell fusion led to reexpression of Chinese hamster HPRT. It did not restore the expression of human alpha-galactosidase. Since PEG-1000 treatment of HPRT- Chinese hamster cells in the absence of human cells yielded no HPRT+ cells, it is concluded that the element responsible for the restoration of rodent HPRT was contributed by the human cells and not by the agent employed to promote fusion.

Twenty-three silver fox x hamster somatic cell hybrid clones were used to assign 15 fox genes: GPI to chromosome 1; PGD to chromosome 2; MDH2 to chromosome 3; ESD to chromosome 6; LDHB to chromosome 8; NP to chromosome 10; LDHA to chromosome 11; APRT, ENO1, and PGM1 to chromosome 12; IDH1 and MDH1 to chromosome 16; and GLA, G6PD, and HPRT to the X chromosome. High-resolution G-banding of human, cat, mink, and fox chromosomes containing homologous regions (according to genetic maps) revealed regions of putative homology. The results lend support to the suggestion that the most considerable karyotypic reorganization of the ancestral genome in the order Carnivora occurred during Canidae formation. The details of karyotypic evolution in mammals are discussed.
