Application

Rhein has been used:
  • as a potassium simplex optimization medium with amino acids (KSOMaa) to induce degeneration in embryos to study its effect on the intracellular and extracellular micro-RNA (miRNA) signature
  • as a fat mass and obesity-associated protein (FTO) inhibitor to study its role in motile ciliogenesis in an m6A-dependent manner in Xenopus embryos
  • as an FTO inhibitor to infer its antiviral action in relation with the SARS-associated coronavirus 2 (SARS-CoV-2) infection

Biochem/physiol Actions

Rhein, a cytotoxic agent, exhibits tumor suppression by activating apoptosis. It is a selective inhibitor of demethylase fat mass and obesity-associated protein (FTO). Rhein is known to participate in various biological processes including obesity and adipogenesis.

The etiology of osteoarthritis (OA) is still a matter of debate. Several factors are known to be involved in the destruction of the articular cartilage. Interleukin-1 (IL-1) plays an important role in the pathogenesis of osteoarthritis (OA) either directly or

Diacerhein and rhein are anthraquinone compounds that ameliorate the course of osteoarthritis. Recent reports also suggest that these compounds may have antiinflammatory properties, but the cellular mechanisms by which they exert antiosteoarthritic and possibly antiinflammatory effects are still incompletely understood.

Adenosine N6-methylation (m6A) is one of the most pervasive mRNA modifications, and yet the physiological significance of m6A removal (demethylation) remains elusive. Here, we report that the m6A demethylase FTO functions as a conserved regulator of motile ciliogenesis. Mechanistically, FTO
