PTPH1 confers breast cancer cell sensitivity to fulvestrant. E and F, PTPH1 overexpression increases the growth inhibition by fulvestrant. PTPH1 was overexpressed by a Tet-on system or a stable transfection, and resultant cells were incubated with fulvestrant as indicated for about 2 weeks. Colony formed was stained and counted. Results shown are normalized to its own solvent control of Vector and PTPH1-overexpressed cells, respectively (means ± SD; n = 3–5) with insets showing PTPH1 overexpression. *, versus vector or no Tet cells for E and F.

MCF7 cells transduced with one of six different ZF-TF-expressing retroviruses selected first in puromycin (the transduction selection marker) and then in fulvestrant for 1 month were grown in the absence of fulvestrant for 7 days and then challenged with 100 nM fulvestrant or vehicle (0.1% ethanol) for 21 days followed by crystal violet staining and visualization. Data are representative of triplicate experiments.

Comparison of cell growth rates (cell number, mean +/2 SEM, n = 8; time in days as indicated) of MCF7 and T47D cells stably transduced with control retrovirus or one of six different ZF-TF-expressing retroviruses (7, 19, 64, 70, 83 and 115) in the presence (blue line) or absence (pink line) of fulvestrant.

|Description||Fulvestrant is an estrogen receptor (ER) antagonist with IC50 of 0.94 nM in a cell-free assay.|
Fulvestrant is an effective inhibitor of the growth of ER-positive MCF-7 (with IC50 of 0.29 nM) but with no effect on the growth of ER-negative BT-20 human breast cancer cells. Fulvestrant causes accumulation of cells in G0/G1 and also reduces the proportion of cells capable of continued DNA synthesis.  Fulvestrant competitively inhibits binding of oestradiol to the estrogen receptor. Fulvestrant blocks nuclear localization of the ER through impairing receptor dimerisation, and energy-dependent nucleo-cytoplasmic shuttling. Because of the instability of fulvestrant-ER complex, the binding of Fulvestrant with ER finally results in accelerated degradation of the ER protein.  Fulvestrant (10 nM) not only decreases IGF-IR mRNA levels but also decreases the half-life.  Treatment with 100 μM Fulvestrant leads to a time dependent increase of TNFR1 and TRADD steady-state mRNA levels in MCF-7 cells.  Fulvestrant is capable of down-regulating androgen receptor expression and diminishes androgenic responses in LNCaP human prostate cancer cells. Fulvestrant also significantly attenuates R1881-stimulated growth by 70%.  Fulvestrant is able to modulate mitosis and cell death in immature cerebellar neurons via rapid activation of MAPK. 
|In vivo||Fulvestrant is devoid of uterotropic activity, and when co-administered with estradiol, it effectively blocks the uterotropic action of estradiol with ED50 of 0.06 mg/kg/day s.c. in immature female rats. A single s.c. injection of 5 mg of Fulvestrant suspension blocks completely the growth of MCF-7 xenografts. The growth of transplants of the BrlO human breast tumor is also suppressed effectively by 10 μM Fulvestrant.  Fulvestrant (10 mg/rat, s.c.) reduces the androgen receptor expression, ERK1/2 phosphorylation and cell proliferation in the rat ventral prostate.  Fulvestrant also displays anti-angiogenesis in the chick egg chorioallantoic membrane. |

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
Is there any information for the half-life of fulvestrant (Cat No.S1191)?
S1191, is about 13.5 to 18.5 hours in vivo: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2750771/. The half life of these compounds in cell culture might be different and we generally recommend replenishing with fresh drug every 24-48 hours.
