Everything below concerns nuclear receptor. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-10-02. Where a claim depends on a specific study, the study is described rather than over-claimed.
REV-ERB proteins help regulate daily cycles in gene expression, including genes tied to lipid and glucose metabolism. SR9009 binds these receptors and alters their activity in cell and animal experiments. Consequences observed in rodents include changes in skeletal muscle oxidative capacity, blood lipid levels, and exercise performance. The precise chain from receptor occupancy to whole-body effects is still an active area of study. Human responses cannot be assumed from rodent data.
Most published work on SR9009 consists of preclinical studies. It is widely sold as a research chemical, a category that does not imply safety, efficacy, or pharmaceutical-grade quality. Sports anti-doping organizations have listed SR9009 as a prohibited substance, and its presence in an athlete sample can lead to sanctions. Legal status differs by country; in several jurisdictions it is not approved for human consumption and may be treated as an unapproved new drug.
Preclinical reports describe effects on exercise endurance, mitochondrial content, and lipid profiles in rodents, but these findings come from specific experimental conditions. Many studies use high doses or delivery methods that may not translate directly to human use. SR9009 has been reported to have low oral bioavailability and a short half-life, which complicates interpretation of oral dosing studies. It is not established as safe or effective for any indication. Literature discussions often separate its pharmacological mechanism from unverified claims made in fitness and supplement markets.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. It is not an approved medicine and has no established human therapeutic use. The compound appears in scientific literature as a tool for probing circadian and metabolic regulation. Online sellers often label it as a research chemical, sometimes using the nickname Stenabolic. Its chemical identity is distinct from selective androgen receptor modulators, stimulants, and peroxisome proliferator-activated receptor delta agonists. Researchers use it mainly in cell and animal experiments.

Research interest in SR9009 grew from studies of circadian biology and metabolic disease. Preclinical reports describe effects on exercise capacity, muscle metabolism, and blood lipid levels in rodents, but these findings come from controlled laboratory settings. The compound has low oral bioavailability in animals, which limits systemic exposure after swallowing. Investigators often use injected routes in experiments to achieve measurable plasma concentrations. Human clinical data are sparse, no approved therapeutic product exists, and whether animal effects translate to humans remains an open question.
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 and metabolic gene expression. In laboratory experiments, SR9009 binds these receptors and alters transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. It is not a naturally occurring compound and has no approved therapeutic use. Research interest stems from its ability to modify energy metabolism in cells and animal models.
In rodent studies, SR9009 has been reported to increase mitochondrial content in skeletal muscle and improve exercise endurance under some conditions. These findings led to popular descriptions such as an exercise mimetic, although that term oversimplifies the biology. Effects vary by dose, timing, tissue, and model. The compound's influence on circadian pathways means that time of administration can matter in experiments. Whether similar metabolic changes occur in humans remains largely unexplored in controlled published trials.
At the molecular level, SR9009 binds the ligand-binding domain of REV-ERB and strengthens recruitment of corepressor proteins such as NCoR and HDAC3. This increases repression of target genes, including Bmal1 and other clock-controlled and metabolic genes. In rodent studies, such changes have been linked to altered lipid handling, glucose metabolism, and energy expenditure. The precise chain of events between receptor binding and whole-body effects remains an active area of research. Findings in animals do not automatically translate to humans.
Laboratory studies often administer SR9009 by injection because oral absorption appears poor in rodents. Reported pharmacokinetic properties include rapid metabolism and low systemic exposure after oral dosing. Human pharmacokinetic data are sparse, so absorption, distribution, metabolism, and excretion in people are not well defined. Some research explores related REV-ERB compounds with improved drug-like properties. Regulatory approval for any REV-ERB agonist as a human medicine has not been granted to date.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ, also called NR1D1 and NR1D2. These receptors help regulate circadian rhythms and metabolic gene programs. The compound was developed for laboratory research, not as an approved therapeutic. Its identity is distinct from steroid hormones and selective androgen receptor modulators. Scientific interest centers on how REV-ERB activation changes gene expression in cells and animal models.
Natural Selection 2 is the sequel to Natural Selection. Natural Selection 2 started development using the Source Engine, but their development blog later announced [1] Archived 2011-07-20 at the Wayback Machine that Unknown Worlds had moved to the Spark engine, an engine they created themselves. Natural Selection 2 has the same basic gameplay as Natural Selection, but with new weapons and abilities. It was released commercially on Steam. According to an interview with the game director, Charlie Cleveland (Flayra), the sequel continues where the original left off and features environments that are dark and denser. Several gameplay modes once available only as community-developed mods (such as Marines vs. Marines) became officially supported. In addition, a major new feature of Natural Selection 2 is dynamic infestation [2] Archived 2006-12-23 at the Wayback Machine, released in December 2006. The proposed feature would dynamically generate bacterial infestation based on what areas of the map the alien team controlled. The alpha testing of Natural Selection 2 began on 26 July 2010. The game was released on October 30, 2012.

(2026) report evidence from the study of carbon and oxygen stable isotope compositions of mammal fossils from the Pinturas Formation (Argentina) indicative of presence of a diverse range of habitats in Patagonia during the Miocene, and interpret the diversity of the primate assemblage from the studied formation as likely linked to habitat diversity. Cooke et al. (2026) report the first discovery of mandibular remains of Stirtonia victoriae from the La Victoria Formation (Colombia), and interpret their anatomy as indicative of leaf-eating adaptations of the studied monkey. Urciuoli et al. (2026) determine the phylogenetic relationships of early members of Catarrhini on the basis of the study of the semicircular canal and vestibule shape in Saadanius, Pliobates, Ekembo and Victoriapithecus, interpret Saadanius as most likely to be a stem catarrhine that evolved ossified tubular ectotympanic independently from crown catarrhines, and interpret pliopithecoids as most likely to be stem catarrhines closer to the crown group than Saadanius. Arias-Martorell et al. (2026) report evidence of similarities of shape of the radial head of Pliobates cataloniae and extant apes, and interpret Pliobates as better adapted to climbing than to behaviors involving forelimb-dominated suspension. Arias-Martorell et al. (2026) compare the shape of the distal part of the humerus of Pliobates cataloniae and other extinct and extant simians, and interpret Pliobates as unlikely to perform acrobatic suspensory behaviors seen in extant gibbons.
Embryonic mitochondrial transplant and protofection have been proposed as a possible treatment for inherited mitochondrial disease, and allotopic expression of mitochondrial proteins as a radical treatment for mtDNA mutation load. In June 2018 Australian Senate's Senate Community Affairs References Committee recommended a move towards legalising MRT. Research and clinical applications of MRT were overseen by laws made by federal and state governments. State laws were, for the most part, consistent with federal law. In all states, legislation prohibited the use of MRT techniques in the clinic, and except for Western Australia, research on a limited range of MRT was permissible up to day 14 of embryo development, subject to a license being granted. In 2010, the Hon. Mark Butler MP, then Federal Minister for Mental Health and Ageing, had appointed an independent committee to review the two relevant acts: the Prohibition of Human Cloning for Reproduction Act 2002 and the Research Involving Human Embryos Act 2002. The committee's report, released in July 2011, recommended the existing legislation remain unchanged Currently, human clinical trials are underway at GenSight Biologics (ClinicalTrials.gov # NCT02064569) and the University of Miami (ClinicalTrials.gov # NCT02161380) to examine the safety and efficacy of mitochondrial gene therapy in Leber's hereditary optic neuropathy.

Dentogingival junction The dentogingival junction consists of three epithelial components: the gingival epithelium, which covers the external gingival surface; the sulcular epithelium, which lines the gingival sulcus; and the junctional epithelium (JE), which forms a specialized epithelial attachment between the gingiva and the tooth surface. The junctional epithelium is of particular importance in assessing clinical attachment level (CAL). In periodontal health, the JE is located at or near the cemento-enamel junction (CEJ). In periodontitis, inflammatory processes lead to apical migration of the JE along the root surface, which represents true loss of periodontal attachment.
At the surface of a stationary liquid in a vessel gravitational potential energy is large but liquid pressure is low. At the bottom of the vessel, all the gravitational potential energy is converted to pressure. The two energy components change linearly with the depth so the sum of pressure and gravitational potential energy per unit volume is constant throughout the volume of the fluid. The units of pressure are equivalent to energy per unit volume. (In the SI system of units, the pascal is equivalent to the joule per cubic metre.) Mathematically, it is described by Bernoulli's equation, where velocity head is zero and comparisons per unit volume in the vessel are
