BMP4 expression in the developing rat retina.

We investigated the expression of bone morphogenetic protein-4 (BMP4) in the developing retina. At E19, we found very intense BMP4 immunoreactivity (IR) in the nerve fiber layer. At P1, the inner plexiform layer exhibited very strong BMP4-IR. Thereafter, abundant BMP4 expression was kept to the adult period. These results suggest that BMP4 plays pivotal roles in the retina not only in the early embryonic period but also in the late embryonic and postnatal periods, and even in the adult.

A single-nucleotide polymorphism tagging set for human drug metabolism and transport.

Interindividual variability in drug response, ranging from no therapeutic benefit to life-threatening adverse reactions, is influenced by variation in genes that control the absorption, distribution, metabolism and excretion of drugs. We genotyped 904 single-nucleotide polymorphisms (SNPs) from 55 such genes in two population samples (European and Japanese) and identified a set of tagging SNPs that represents the common variation in these genes, both known and unknown. Extensive empirical evaluations, including a direct assessment of association with candidate functional SNPs in a new, larger population sample, validated the performance of these tagging SNPs and confirmed their utility for linkage-disequilibrium mapping in pharmacogenetics. The analyses also suggest that rare variation is not amenable to tagging strategies.
