Summary of "A newly synthesized oleanolic acid derivative inhibits the growth of osteosarcoma cells in vitro and in vivo by decreasing c-MYC-dependent glycolysis."

Osteosarcoma (OS) is the primary malignant bone tumor with a peak incidence in children and adolescents. However, the little molecular mechanism of pathogenesis has been known and it is urgent to develop new therapeutical strategies to improve outcomes for patients. CDDO-NFM (N-formylmorpholine substituent of CDDO) is a newly synthesized triterpenoid, which is a derivative of oleanolic acid. In this study, we explored whether CDDO-NFM possesses a potential antitumor effect and revealed its molecular mechanism. We found that CDDO-NFM efficiently inhibited cell growth of OS cells and this inhibitory effect was independent of apoptosis-related and cell-cycle-related proteins. CDDO-NFM could decrease the level of glucose uptake, the generation of lactate, and the production of adenosine triphosphate to block the process of glycolysis. In vitro and in vivo cell-based assays showed that CDDO-NFM inhibited glycolysis via degradation of c-MYC rather than activating peroxisome proliferator-activated receptor gamma. Finally, CDDO-NFM could reduce tumor volume and weight with low toxicity, and down-regulate the expression of glycolysis-related enzymes in nude mice. Taken together, these results showed that CDDO-NFM might be a promising antitumor compound.

Medical and Biotech [MESH] Definitions

A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin.

A TGF-beta subtype that was originally identified as a GLIOBLASTOMA-derived factor which inhibits the antigen-dependent growth of both helper and CYTOTOXIC T LYMPHOCYTES. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta2 and TGF-beta2 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.

An oleanolic acid from GLYCYRRHIZA that has some antiallergic, antibacterial, and antiviral properties. It is used topically for allergic or infectious skin inflammation and orally for its aldosterone effects in electrolyte regulation.

A plant genus of the family VALERIANACEAE. Members contain ursolic acid and oleanolic acid glycosides, sulfapatrinosides (triterpenoid glycosides), and patriscabrol (iridolactone).

A barbituric acid derivative that acts as a nonselective central nervous system depressant. It promotes binding to inhibitory GAMMA-AMINOBUTYRIC ACID subtype receptors, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.
