Thus, there was no clear correlation between R-band and GC3 of the mapped genes in rat snake.
The genomic locations of each sequence were mapped in human, mouse, rat and pufferfish, where applicable, and the structure of their cognate genes was derived using computer-based predictions, genomic comparisons and analysis of uncharacterized cDNA sequences from human and macaque.
Significant characteristics of the KIF27 genes mapped in human, mouse and rat included a conserved 18 exon arrangement and the existence of at least three mRNAs that resulted from alternative splicing, at least in human.
Multiple genetic determinants of susceptibility to E2-induced mammary cancer, designated Emca1 (E strogen-induced m ammary ca ncer 1) through Emca9, have been mapped in crosses between susceptible ACI rats and resistant COP or BN rats [ 21- 24].
These and other complex traits have been mapped in linkage studies, and the Rat Genome Database (http://rgd.mcw.edu) presently curates 257 quantitative trait loci (QTL) in crosses involving DA and 362 QTL in crosses involving F344 rats, including congenics.
Emca7 was unique among the Emca loci mapped in reciprocal intercrosses between susceptible ACI rats and resistant BN rats in that BN alleles at Emca7 were associated with increased susceptibility to E2-induced mammary cancer.
Seven distinct quantitative trait loci that harbor genetic determinants of susceptibility to 17β-estradiol−induced mammary cancer have been mapped in reciprocal intercrosses between susceptible ACI rats and resistant Brown Norway (BN) rats.
Previous efforts to map variation in other species include strain specific mouse resequencing [ 3, 4], a haplotype mapping in rat [ 5], as well as data mining of public domain resources such as NCBI's dbSNP [ 6].
By using β-radio imager whole-body mapping in rats, we have shown that systematically administered HB-19 is rapidly cleared from blood to become distributed selectively in tissues expressing enhanced levels of surface nucleolin, where a significant proportion still persists even after 24 hours in its active form [39].
