Biological Activity

Description Cytosporone B is a naturally occurring agonist for nuclear orphan receptor Nur77(NR4A1) with an EC50 of 0.278nM.
Targets
Nur77 [1]
(Cell-free assay)
0.278 nM(EC50)
In vitro

Cytosporone B effectively decreases the TGF-β1-dependent elevated expression of fibrotic markers in vitro.[2]
In vivo

Cytosporone B, an NR4A1 agonist, effectively suppresses fibrogenesis in mouse endometriotic tissue.[2]

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    Human ectopic endometrial stromal cells (EESCs), normal endometrial stromal cells (NESCs)

  • Concentrations

    1 μM

  • Incubation Time

    24 h

  • Method

    After being incubated with Csn-B (1 μmol), siRNA, and TGF-β1 for 24 h, total RNA from cells is extracted with TRIzol reagent for PCR analysis. Proteins from cells Are extracted for Western blot analysis.
