A practical reference on REV-ERB agonist: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
This page was last updated on 2025-09-24 and is reviewed periodically as new material appears.
Regulatory and sporting contexts treat SR9009 as a prohibited substance in many elite competitions. Its presence on banned lists reflects concerns about performance enhancement and unknown long-term safety. Analytical chemists have developed methods to detect the parent compound and its metabolites in urine and blood. Literature discussions distinguish between in vitro potency, animal pharmacology, and anecdotal human reports. The latter are difficult to verify because products sold online may lack purity or contain different compounds.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. These receptors help regulate circadian rhythms, lipid metabolism, and inflammatory gene expression. In cell and animal experiments, SR9009 alters transcription of clock-controlled genes and metabolic pathways. The compound is not a hormone and does not resemble classical steroid structures. Its activity depends on binding to the ligand-binding domain of REV-ERB, where it can modify corepressor recruitment.
REV-ERB proteins typically suppress gene expression by recruiting corepressor complexes to DNA response elements. SR9009 binds these receptors and strengthens that repressive action in cell-based assays. Studies in rodents have reported changes in lipid handling, mitochondrial function, and exercise capacity after treatment. Such findings are often cited as evidence for metabolic effects, but species differences and limited pharmacokinetic data make direct translation to humans uncertain. Researchers continue to examine which effects are robust and which depend on specific experimental conditions.
SR9009 is frequently discussed alongside other REV-ERB ligands, including synthetic agonists and natural heme-related molecules. Its selectivity for REV-ERB over related nuclear receptors has been measured in binding and reporter assays, though off-target activity at higher concentrations is possible. The compound is prohibited in sport by the World Anti-Doping Agency, and it is not approved for any medical use in major jurisdictions. Products sold online may be labeled as research chemicals, and their identity and purity are not guaranteed by regulatory review.
SR9009 is a synthetic small molecule that acts on the nuclear receptors REV-ERBα and REV-ERBβ. These receptors are part of the circadian clock machinery and normally repress transcription of certain target genes. In laboratory research, SR9009 is used as a chemical tool to study how REV-ERB activity influences metabolism, inflammation, and daily biological rhythms. The compound is not an approved medicine, and its effects in humans remain largely uncharacterized. It is often described as an investigational agent rather than a therapeutic product.

Analytical chemists detect SR9009 with liquid chromatography-tandem mass spectrometry, commonly abbreviated LC-MS/MS. Sample preparation may involve protein precipitation, liquid-liquid extraction, or solid-phase extraction before analysis. Laboratories can target the parent compound or its metabolites, depending on the matrix and the purpose of testing. Anti-doping methods require sensitive and specific assays because concentrations in biological samples can be low. Reference standards and validated methods are essential for reliable identification and quantification.
Regulatory agencies have not approved SR9009 for human therapeutic use. It is typically sold as a research chemical with labels stating that it is not for human consumption. The World Anti-Doping Agency prohibits the substance in sport, generally under the category of non-approved substances. Customs and national laws may restrict importation, sale, or possession. Product quality and legal status can vary by country and vendor, and therapeutic claims are not permitted in regulated advertising because the compound lacks approval.
SR9009 is a synthetic small molecule studied as an agonist of REV-ERB nuclear receptors. REV-ERB alpha and REV-ERB beta help regulate circadian rhythms and metabolic gene expression. In laboratory research, SR9009 has been used to probe how these receptors affect skeletal muscle, liver, and adipose tissue. The compound was identified in academic drug-discovery work and is often described in scientific literature by its chemical name and research code. It is not an approved medicine, and human clinical data remain limited or absent.
SR9009 binds REV-ERB receptors and alters their repressive activity on target genes. This action can change transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. In rodent studies, treated animals have shown changes in muscle oxidative capacity and exercise performance, though effects vary by dose, duration, and model. The precise molecular steps connecting receptor binding to whole-body outcomes are still an active area of investigation. Findings in animals do not automatically translate to humans.
Because REV-ERB receptors are core clock components, SR9009 has been examined for effects on daily rhythms as well as metabolism. Research has explored whether the compound can shift or reinforce circadian gene expression in tissues such as liver and muscle. Some studies report improved metabolic markers in obese or diabetic mice, while others show context-dependent responses. Questions remain about which effects are direct, which are secondary to timing, and how they might differ across species.
Mechanistically, SR9009 binds the ligand-binding domain of REV-ERBα/β and enhances recruitment of corepressor complexes. This represses target genes rather than activating them. Because REV-ERB proteins normally compete with ROR proteins at shared response elements, the net effect depends on tissue and timing. Researchers use SR9009 to probe how nuclear receptor signaling links the clock to metabolism, inflammation, and muscle biology. Findings are largely preclinical, and the precise contribution of each receptor subtype remains under study.
SR9009 is frequently discussed in fitness and research-chemical contexts, yet it has no approved medical indication. Regulatory agencies have not authorized it for human use, and it is not a standard prescription drug. Some sports organizations list it as a prohibited substance because of its potential performance-enhancing properties. Published human data are sparse, so claims about its effects in people often rely on animal models or anecdotal reports. Quality and identity of online materials can vary widely.
=== Bedding plants === In 2005 in the United States, Viola cultivars (including pansies) were one of the top three bedding plant crops and 111 million dollars' worth of flats of Viola were produced for the bedding flower market. Pansies and violas used for bedding are generally raised from seed, and F1 hybrid seed strains have been developed which produce compact plants of reasonably consistent flower coloring and appearance. Bedding plants are usually discarded after one growing season.
Breteni was upset over this interaction because it took them two years to be able to come out with her daughter’s results and only after an interaction with Dr. Lisa Sanders. Dr. Sanders believed this was because they might have initially forgotten to share the results and didn't want to ligate any misinterpretations. Once Breteni received the results it was shown that Kamiyah had a break in a gene that wasn't inherited from her mother or father, it created itself. Specifically a break within the KCNMA1 gene, and she was the first patient of her kind, she's “groundbreaking”. The NIH said that it would take more patients with the same illness and a doctor to “peg” it to be able to create a disease grouping for diagnosis. When Dr. Lisa Sanders created the column for Kamiyah, instead of asking for the readers to chime in for their diagnosis, she went out looking for readers who would have the same symptoms/gene break as her. From the publication of the column, Breteni was able to find dozens of people who themselves or their children had the same KCNMA1 gene mutation. There was also a scientist who reached out to Dr. Lisa Sanders, who had based the last 20 years of her career on researching the specific ion pathway for the KCNMA1 gene. The scientist goes into detail about the gene and how it regulates the amount of potassium that enters the cells and as a result this affects the brain wave levels corresponding to movement and in theory would create the fainting episodes.
The new 32nd district covers several suburban areas directly north and northeast of Dallas, including most of the Dallas County portion of Carrollton and Addison along with all of Richardson (including the Collin County portion) and the northern halves of Garland and Rowlett, as well as the far north side of Dallas itself. The district then stretches eastward and crosses Lake Ray Hubbard to take in suburban Rockwall County and the Lake Tawakoni area, traveling all the way east to such northern Tyler exurbs as Mineola and Gilmer. Prior to redistricting, the incumbent was Democrat Julie Johnson; however, Johnson was drawn out of the 32nd district and into the 24th, ultimately deciding to seek reelection in the 33rd district (see below) and leaving this district as an open seat. In 2024, the new district gave 57.7% of the vote to Donald Trump and 55.2% to Ted Cruz, with Democrats only considered competitive in the Dallas County and Richardson portion of the otherwise heavily Republican district.
=== Fat === Most of a camel's fat is stored in its hump, which can weigh up to 80 pounds (36.3 kg). This fat store allows it to go long periods of time without eating. If a camel continuously uses its fat stores without replenishing, the humps will eventually become flaccid in appearance. The hump also aids with heat regulation, as nearly all of its fat is stored in the hump, as opposed to even distribution throughout the body. During the day, the camel's hump stores heat, which is then dissipated through the camel's body at night, allowing for better retention of water compared to other thermoregulation methods.

Art museums include the Sabauda Gallery, the Museo Civico d'Arte Antica, Pinacoteca Giovanni e Marella Agnelli, the Accademia Albertina, the Gallery of Modern and Contemporary Art, and the Diocesan Museum of Turin. After it had been little more than a town for a long time, in 1559 the Duke Emmanuel Philibert of Savoy made Turin the capital of his domains. The Duke had the ambition to transform the city into a major artistic and cultural capital, and in the following centuries numerous artists were to work at the Savoy court, especially architects and planners such as Carlo di Castellamonte and his son Amedeo, Guarino Guarini and, in the 18th century, Filippo Juvarra and Benedetto Alfieri. As for the painting and the visual arts, Turin became a point of reference, especially in the 20th century. In the 1920s, the painter Felice Casorati inspired a number of students called The group of six of Turin and these included Carlo Levi, Henry Paolucci, Gigi Chessa, Francesco Menzio, Nicola Galante and Jessie Boswell. Artists born in Turin include the sculptor Umberto Mastroianni and the architect Carlo Mollino. Between the 1960s and the 1970s, the international centre of Turin (Arte Povera), the presence in the city of artists such as Alighiero Boetti, Mario Merz, Giuseppe Penone, Piero Gilardi and Michelangelo Pistoletto. In those years there was a strong artistic influence of designer Armando Testa. Artists currently operating in the city include Ugo Nespolo and Carol Rama.

Although the process of fermentation was not fully understood until Louis Pasteur's work in 1857, it is still the first use of biotechnology to convert a food source into another form. Before the time of Charles Darwin's work and life, animal and plant scientists had already used selective breeding. Darwin added to that body of work with his scientific observations about the ability of science to change species. These accounts contributed to Darwin's theory of natural selection. For thousands of years, humans have used selective breeding to improve the production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops. In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In 1917, Chaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicum, to produce acetone, which the United Kingdom desperately needed to manufacture explosives during World War I. Biotechnology has also led to the development of antibiotics. In 1928, Alexander Fleming discovered the mold Penicillium. His work led to the purification of the antibiotic formed by the mold by Howard Florey, Ernst Boris Chain and Norman Heatley – to form what we today know as penicillin.

=== Supplementation === Copper supplements can prevent copper deficiency. Copper supplements are not prescription medicines, and are available at vitamin and herb stores and grocery stores and online retailers. Different forms of copper supplementation have different absorption rates. For example, the absorption of copper from cupric oxide supplements is lower than that from copper gluconate, copper sulfate, or carbonate. Supplementation is generally not recommended for healthy adults who consume a well-balanced diet which includes a wide range of foods. However, supplementation under the care of a physician may be necessary for premature infants or those with low birth weights, infants fed unfortified formula or cow's milk during the first year of life, and malnourished young children. Physicians may consider copper supplementation for 1) illnesses that reduce digestion (e.g., children with frequent diarrhea or infections; alcoholics), 2) insufficient food consumption (e.g., the elderly, the infirm, those with eating disorders or on diets), 3) patients taking medications that block the body's use of copper, 4) anemia patients who are treated with iron supplements, 5) anyone taking zinc supplements, and 6) those with osteoporosis. Many popular vitamin supplements include copper as small inorganic molecules such as cupric oxide. These supplements can result in excess free copper in the brain as the copper can cross the blood-brain barrier directly. Normally, organic copper in food is first processed by the liver which keeps free copper levels under control.
