The purpose of this investigation was to elucidate the en-zymic programs of pyrimidine, carbohydrate, and purine me tabolism and the pattern of pyrimidine and purine ribonucleo-tides in two lines of human colon carcinoma xenografts of different growth rates. The slower-growing colon tumor line was well differentiated; the more rapidly growing line was a(More)
NMDA (N-methyl-d-aspartate) receptor, a subclass of the ionotropic glutamate receptors, participates in synaptic transmission and plays important roles in various higher brain functions in the vertebrate central nervous system. Here, we report the cloning of two NR1 subunits of tilapia (Oreochromis mossambicus). Phylogenetic analysis strongly supports that(More)
The incomplete correlation between the organismal complexities and the number of genes among eukaryotic organisms can be partially explained by multiple protein products of a gene created by alternative splicing. One type of alternative splicing involves alternative selection of mutually exclusive exons and creates protein products with substitution of one(More)
