Target gene or protein TFF1, GREB1, CCND1, ERG3, PKIB, CTSD, CXCL12, PGR, MYC
Gene or Protein evidence Germacrone treatment significantly reduced the mRNA level of TFF1, GREB1, and PGR, which are well-known ERα target genes. The expression of CCND1 and MYC, which are other ERα target genes involved in cell cycle, was also significantly inhibited by germacrone. Compared with the gene expression of cells treated with DMSO (vehicle), the E2-induced expression of TFF1, GREB1, CCND1, ERG3, PKIB, CTSD, CXCL12, PGR, and MYC was significantly reduced following treatment of MCF-7 cells with germacrone
Target pathways ERα signaling pathway.
IC50 NA
Potency Germacrone inhibits the recruitment of ERα to the estrogen response element on chromatin and consequently compromises the binding of switch/sucrose non-fermentable chromatin remodeling complex and RNA polymerase II to target gene promoter, thereby inhibiting the estrogen-induced chromatin accessibility.
Cell line/ mice model MCF-7
Additional information  In addition, germacrone efficiently potentiates the antitumor activity of methotrexate and 5-fluorouracil.
