Description: MA1-216 detects thyroid hormone receptor (TR) beta-1 in human, mouse, rat, and transformed bacterial cells. This antibody is specific for the TR beta-1 isoform. MA1-216 has been successfully used in Western blot, immunocytochemistry, immunoprecipitation and gel shift procedures. By Western blot, this antibody detects a 52 and a 55 kDa protein representing recombinant TR expressed in E. coli. The two different sizes represent two different translational starting points. Immunocytochemical staining of TR beta-1 in intact GH3 cells with MA1-216 results in nuclear staining. When levels of expression of the transfected receptor are high, cytoplasmic staining is seen along with nuclear staining. Immunoprecipitation and gel super shift experiments show that MA1-216 reacts with the unliganded, liganded, and DNA binding forms of the receptor. The MA1-216 immunogen is purified human TR beta-1 overexpressed in E. coli. This antibody recognizes an epitope in the A/B domain of human TR beta-1, amino acid residues 1-101.

Experimental details: Figure 4 Characterization of TRbeta binding near induced genes. A. Patterns of TRbeta binding depicted at representations of individual target gene loci (LDLR, BCL3, NCOR2,ADSSL1 and SOX7). Blue bars represent genomic binding regions, and the vertical red lines represent peaks, as classified by QuEST. The horizontal black bars are regions analyzed by ChIP-PCR (locations of primer amplification). Observed binding patterns included 5', 3' and intronic binding events, as shown in genomic data tracks (UCSC Genome Browser). Putative regulatory elements, identified through sequence analysis of the genomic regions indicated, are depicted below bound regions in which they occur. B. QPCR of ChIP analysis confirming DNA binding in regulatory regions of genes. C. Realtime PCR analysis depicting enhancement of transcription of individual loci in Fig. 4A by T3 in the presence of TRbeta. (*P

Experimental details: Figure 6 Links between TR Binding and Adm Transcription. A. Graph showing results of realtime PCR analysis of adm transcription in the B7B cells after six hours of T3 treatment +/-10 ug/ml CHX cotreatment of B7B cells. B. Patterns of TRbeta binding peaks at the adm locus (UCSC Genome Browser), in similar format to Fig. 4 . TRbeta binding events clustered into four regions (R1, R2, R3, R4), upstream and downstream of this transcript, as well as a substantial amount of binding immediately proximal to the transcriptional start site. C. Binding of TRbeta was confirmed by realtime ChIP PCR analysis in B7B cells at the regions indicated (ChIP primers are depicted by horizontal bars in B). D. The proximal promoter region of adm (corresponding to R2) conferred T3-dependent increases in luciferase activity upon a standard reporter after transfection into B7B. E. Results of gel shift confirming direct TRbeta binding to two putative response elements, designated TRE-1 and TRE-2 that were found in R2 at positions marked in Fig. 6B . Individual lanes show shifts obtained with elements and RXRalpha-TRbeta +/- competitor DNA or mutated versions of both elements. F. Luciferase reporter assays confirming that TRE-1 and TRE-2 confer T3 responsiveness on a reporter gene. (*P

Experimental details: Figure 7 Intergenic binding events. A. Three intergenic binding peaks were selected and analyzed for the presence of recognizable TR binding motifs (sequences of motifs listed). B. Results of qPCR ChIP analysis confirming binding of TRbeta to the intergenic regions depicted in Fig. 7A (top panels) and induction of H3 acetylation near sites (bottom panels). C. Results of luciferase reporter assays, with indicated constructs containing intergenic elements described in Fig. 7A , confirming that each element confers T3 induction. (*P

Experimental details: Fig. 10 Effects of TH replacement on TH-related proteins in THRSP OE mice. The TH-related proteins were evaluated following 7 days of LT3 and LT4 (10 mg kg -1 ) treatment. On the last day of the treatment, the brains were harvested, and the striatum was subjected to western blot analysis. a Representative blots for specific protein targets. b MCT8, c TRalpha, and d TRbeta protein levels ( n = 6 mice/group; b two-way ANOVA, F (1,30) = 4.96, P = 0.034; c two-way ANOVA, F (1,30) = 14.4, P < 0.001; d two-way ANOVA, F (1,30) = 0.123, P = 0.728). TH replacement improved the striatal MCT8 and TRalpha levels in THRSP OE mice. Values are presented as the mean +- S.E.M. * P < 0.05 (relative to WT) and # P < 0.05. ## P < 0.01 (relative to VEH treatment), by two-way ANOVA with Bonferroni's multiple comparison tests.
