  • Pancreatic cancer cell lines (CFPAC-1 and BxPC-3) were treated with siHIF-1 and 2-ME and then evaluate the expression HIF-1α, CRT and P-eIF2α by Western blotting experiment.

    Oncotarget, 2015, 6(4): 2250-62. 2-Methoxyestradiol (2-MeOE2) purchased from Selleck.

    The knockdown of Set7 by Set7-shRNA-2 in RCC4 cells increased GST expression, but this effect was not evident when HIF-2 activity was inhibited by addition of 2ME2 (50 ng/µl,18 h), as revealed by semi-quantitative real-time PCR assays.

Biological Activity

Description 2-Methoxyestradiol (2-MeOE2) depolymerizes microtubules and blocks HIF-1α nuclear accumulation and HIF-transcriptional activity. Phase 2.
HIF-2α [1]
(Rat aortic smooth muscle A-10 cells)
Microtubule Associated [1]
(Cell-free assay)
HIF-1α [3]
(MDA-MB-231 cells)
In vitro

2-Methoxyestradiol exhibits the inhibitory activity of cellular proliferation in a breast carcinoma cell line MDA-MB-435 and an ovarian carcinoma cell line SK-OV-3 with IC50 of 1.38 μM and 1.79 μM, respectively. Furthermore, 2-Methoxyestradiol also inhibits cellular microtubule depolymerization in rat aortic smooth muscle A-10 cells with EC50 of 7.5 μM. [1] 2-Methoxyestradiol inhibits proliferation of MCF-7 and BM cells with IC50 of 52 μM and 8 μM. [2] In MDA-MB-231 cells, 2-Methoxyestradiol inhibits HIF-1-mediated transcriptional activation of target genes without affecting the transcription of HIF-1α itself. [3] A recent study shows that 2-Methoxyestradiol (0.5 μM), blocks TGF-β3-induced expression of collagen (Col) type I(αI), Col III(αI), plasminogen activator inhibitor (PAI) 1, connective tissue growth factor (CTGF), and α-smooth muscle actin (α-SMA). Moreover, 2-Methoxyestradiol ameliorates TGF-β3-induced Smad2/3 phosphorylation and nuclear translocation, and inhibits TGF-β3-induced activation of the PI3K/Akt/mTOR pathway. [4]

In vivo In a 9L rat glioma (9L-V6R) rat model, 2-Methoxyestradiol significantly decreases HIF-1 activity and inhibits the tumor growth in a dose-dependent manner by 4-fold reduction for 60 mg/kg/day, and 23-fold reduction for 600 mg/kg/day, respectively. [5]

Microtubule depolymerizing activity:

The effects of 2-Methoxyestradiol on cellular microtubule depolymerization are determined by indirect immunofluorescence techniques in rat aortic smooth muscle A-10 cells. Microtubules are visualized using a β-tubulin antibody. Three viewers determines the percent microtubule loss for each treatment concentration. The data are averaged and plotted as percent microtubule loss versus drug concentration and the EC50s for microtubule depolymerization calculated from the log dose–response curves.

  • Cell lines: MDA-MB-435 and SK-OV-3
  • Concentrations: 0-20 μM
  • Incubation Time: 48 hours
  • Method: The sulforhodamine B (SRB) assay is used to evaluate the antiproliferative activity of 2-Methoxyestradiol in the MDA-MB-435 and SK-OV-3 cell lines. Cells a plated into 96-well plates and allowed to grow and attach for 24 hours followed by addition of 2-Methoxyestradiol or vehicle controls. The cells are incubated with drugs for 48 hours and then the cellular protein is fixed, stained, and concentration determined by absorbance at 560 nm. Log dose–response curves are constructed for each experiment and the IC50 for inhibition of proliferation determined.
