TABLE 4

AHR-dependent effects of TCDD

The 25 ProbeSets that are most up-regulated and the 24 most down-regulated are shown. Both transient (UniGene) and stable(LocusLink) gene identifiers are given. ProbeSets that carry no LocusLink could be mapped to a UniGene cluster, but that cluster did not correspond to a RefSeq gene. ProbeSets that carry no name and no UniGene cluster identifier could not be mapped to any cluster of transcribed sequences and may represent repetitive or nonspecific sequences. In some cases, the array contains multiple ProbeSets that map to the same gene; thus, the same gene name can appear at multiple places in the table. In cases in which genomic sequence is available, the number of AHRE-I and AHRE-II elements found in the region -5000 to +1000 bp relative to the TSS are given; see Materials and Methods for the sequence of each element. “M” values indicate the magnitude in log2-space of each contrast. For example, an effect of -3 refers to an 8-fold reduction in expression, whereas an effect of +2 refers to a 4-fold increase in mRNA levels. The abbreviated names of genes that are discussed in the text are shown in boldface type in parentheses. A full list of all responsive genes is available in Supplemental Table S2.
