Project description:ChIP-seq data from mouse liver over-expressing GFP and fed a PTU diet and treated with saline, or overexpressing biotinylated TRb1 and GFP and fed a PTU diet, treated with either saline or T3 Mouse liver was infected with adenovirus that either expressed only GFP or GFP and biotinylated TRb1 and were fed a PTU diet, followed by injections with only saline (GFP-only livers) or with saline or T3 (Biotinylated-TRb1 and GFP livers). ChIP assays were performed using streptavidin agarose to capture biotinylated TRb1 followed by library construction and sequencing.

Project description:We over-expressed biotinylated-thyroid hormone receptor beta 1 (TRb1) in mouse liver using an adenovirus in order to perform ChIP-seq experiments. These microarrays were performed to determine gene expression changes in response to tri-iodothyronine (thyroid hormone; T3) stimulation. A control GFP adenovirus was used and gene expression from these livers was also done as a comparison. We performed microarrays from Ad-GFP-infected propylthiouracil (PTU)-fed livers injected with either saline or T3 and Ad-TRb1-GFP infected livers injected with either saline or T3. RNA was extracted from livers of biotin ligase (BirA)-expressing mice that had been infected with either Ad-GFP or Ad-TRb1, fed with PTU for 3 weeks followed by saline or T3 injections for 4 consecutive days.

Project description:We used microarrays to investigate differential gene expression in different thyroid hormone receptor beta mouse models. Hypothyroid wild type, TRbeta KO and TRbeta GS mutant mice were treated with T3 or vehicle alone. Microarray analysis revealed that the gene expression pattern in TRbeta GS mutant mice was similar to that in TRbeta KO mice.

Project description:Using tadpoles mutant for thyroid hormone receptor alpha (thra), we show that TRa is required for thyroid hormone (T3) induction of cell proliferation in the brain. RNA-sequencing showed that the TRa is required for 95% of the gene regulation responses to T3.

Project description:Synthetic selective thyroid hormone (TH) receptor (TR) modulators (STRMs) exhibit beneficial effects on dyslipidemias in animals and humans and reduce obesity, fatty liver and insulin resistance in preclinical animal models. STRMs differ from native THs in preferential binding to the TRβ subtype versus TRα, increased uptake into liver and reduced uptake into other tissues. However, selective modulators of other nuclear receptors (NRs) exhibit important gene-selective actions which have been attributed to differential effects on receptor conformation and dynamics and these effects can have profound influences in animals and humans. While there are suggestions that STRMs could exhibit such gene-specific actions, the extent to which these effects are actually observed in vivo has not been explored. Here, we show that saturating concentrations of the main active form of TH, triiodothyronine (T3), and the prototype STRM GC-1 induce identical gene-sets in livers of euthyroid and hypothyroid mice and a human cultured hepatoma cell line that only expresses TRβ, HepG2. We find one case in which GC-1 exhibits a modest gene-specific reduction in potency versus T3, at angiopoietin-like factor 4 (ANGPTL4) in HepG2. Investigation of the latter effect confirms that GC-1 acts through TRβ to directly induce this gene. However, this gene-selective GC-1 activity is not related to unusual T3 response element (TRE) sequence, unlike previously documented promoter-selective STRM actions. Together, our data suggest that T3 and GC-1 exhibit almost identical gene regulation properties and that gene-selective actions of GC-1 and similar STRMs will be subtle and rare. We treated HepG2 with vehicle or 10nM ligand (T3 or GC1; n=3 / treatment), analyzing mRNA 24h post treatment [Affymetrix]. We also treated 9-week old euthyroid male C57/Bl6 mice with vehicle or ligand (T3 or GC-1) by a single oral gavage (n=5 per treatment) and also performed a similar study in which mice were first made hypothyroid by two week feeding on iodine deficient diet (n=3-4 per treatment), analyzing mRNA 24h post treatment [Illumina].

Project description:In mammals, increasing data suggests that there exists a complex and bi-directional relationship between thyroid and immune systems. However the existence of such interactions in fish is unknown. Here, we administered the biologically active hormone 3.3�.5-triiodo-L-thyronine (T3) and the anti-thyroid drug, propilthiouracil (PTU) to juvenile rainbow trout and examined the head kidney expression profile with a custom-made microarray enriched in immune-related genes. A seven day-experiment was performed. Fish were divided in 3 groups. First group received 20 µg/g fish feed of T3; second group received 5000 µg/g fish feed of PTU; third group served as control. After 7 days orally administering T3 or PTU, differentially expressed transcript levels from selected immune-related rainbow trout genes were studied in head kidney. Three groups were studied (T3-treated, PTU treated and control), each group having 4 biological replicates (each replicate consisting of 2 pooled fish).
