1,25-Dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) has potent antiproliferative effects characterized by a hampered G(1)/S transition. cDNA microarrays were used to monitor expression of 21,492 genes in MC3T3-E1 mouse osteoblasts at 1, 6, 12, 24, and 36 h after treatment with 1,25(OH)(2)D(3). Statistical analysis revealed a cluster of genes that were strongly(More)
A previous cDNA microarray analysis in murine MC3T3-E1 osteoblasts revealed a cluster of genes involved in cell cycle progression that was significantly down-regulated after a single treatment with 1alpha,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] [L.

Duplicated genes can undergo different fates, from nonfunctionalization to subfunctionalization and neofunctionalization. In particular, changes in regulatory sequences affecting the expression domain of genes seem to be responsible for the latter two fates. In this study we used in silico motif detection to show how alterations in the composition of(More)
Although proven successful in the identification of regulatory motifs, phylogenetic footprinting methods still show some shortcomings. To assess these difficulties, most apparent when applying phylogenetic footprinting to distantly related organisms, we developed a two-step procedure that combines the advantages of sequence alignment and motif detection(More)
