Muristerone A is a natural analog of 20-hydroxyecdysone. It is an agonist of the ecdysteroid receptor (Kd = 1 nM), a nuclear receptor that heterodimerizes with a retinoid X receptor ortholog and regulates arthropod development. Muristerone A is used as an agonist in ecdysone-inducible gene expression systems in mammalian cells. However, it inhibits apoptosis in the human colon carcinoma cell line RKO by inducing the upregulation of Bcl-xL, suggesting limitations in its use in certain types of studies.

Muristerone A-induced nerve growth factor release from genetically engineered human dermal fibroblasts for peripheral nerve tissue engineering.[Pubmed:11429150]
Tissue Eng. 2001 Jun;7(3):303-11.
In this study, human dermal fibroblasts (hDFBs) were genetically modified to release human nerve growth factor (NGF) using an ecdysone-inducible system. NGF cDNA was inserted into the pIND vector and then hDFBs were cotransfected with pIND-NGF and pVgRXR. Muristerone A, an analog of ecdysone, was used as the inducing agent. NGF release from transfected hDFBs was assessed in vitro and in vivo. Transfected hDFBs in the presence of Muristerone A possessed a maximal in vitro release of 8.5 +/- 0.4 pg of NGF/mL per 10(3) cells, demonstrating significantly higher NGF levels compared to control hDFBs. The in vitro release rate curve for transfected hDFBs in the presence of Muristerone A exhibited a maximum of 5.1 +/- 0.2 ng NGF/10(6) cells/day. A PC-12 bioassay demonstrated that the in vitro NGF released is bioactive. When transfected hDFBs in the presence of Muristerone A were placed in vivo in nude rats, NGF levels reach 2074 +/- 257 pg/mL and 1620 +/- 132 pg/mL at 24 and 48 h, respectively. These levels were significantly higher than negative control and wound fluid levels. Results support further in vivo investigation of this molecular "on" switch for peripheral nerve regeneration.
The ecdysone inducible gene expression system: unexpected effects of muristerone A and ponasterone A on cytokine signaling in mammalian cells.[Pubmed:11399528]
Eur Cytokine Netw. 2001 Apr-Jun;12(2):365-7.
Inducible gene expression systems in mammalian cells have been shown to be valuable processes to study the specific function of a protein in differentiation, proliferation or survival/apoptosis. Usually, these systems use as inducible reagents, compounds that are thought to be neutral and devoid of physiological or biologically undesirable effects in mammalian cells. We recently used the ecdysone inducible gene expression system in hematopoietic cells and found that the two inducer analogs of ecdysone, Muristerone A and ponasterone A, altered the signaling pathways induced by IL-3 in the pro-B cell-line, Ba/F3. Indeed, we showed that these two analogs potentiate the IL-3-dependent activation of the PI 3-kinase/Akt pathway, which could ultimately interfere with the growth, and/or survival of these cells.
