Opriate secondary antibodies (Santa Cruz Biotechnology, Santa Cruz, CA, USA) were used at 1:1000?:2000 (v/v) dilutions in PBS + 0.1 Tween 20 for 1 h at room temperature, and the signals were revealed using ECL kit(Thermo Scientific Pierce, Thermo Fisher Scientific, Rockford, USA). The cells were induced with 10nM and 100 nM 17-estradiol (E2) for 24 h.CCK-8 assayCell invasion assays were evaluated using Transwell cell migration plates (Corning, NY, USA) and 8-m pore size Matrigel invasion chambers (BD Biosciences, San Jose, USA) according to the manufacturer’s instructions [23?7]. Cells (1.0 ?104) were seeded in serum-free medium into the upper chamber and allowed to invade towards 10 FBS in the lower chamber. After 24 h incubation in 37 and 5 CO2, the cells invaded through the membrane and adhered to the underside of the membrane. Then cells were fixed and stained with crystal violet. The images were acquired by using NIS Elements image analysis software (Nikon, Tokyo, Japan). For the membrane images, we measure the migrated cells using image analysis software ImagePro Plus 6.0 (Media Cybernetics, Bethesda, USA).Mice modelNude mice were purchased from the Vital River Laboratories (Beijing, China). All animals were used in accordance with institutional guidelines and the current experiments were approved by the Use Committee for Animal Care. All cultures used for injection were sub-confluent and were fed the day prior to use. The harvested cell suspension was washed twice by centrifugation in medium containing serum at room temperature and then resuspended in medium without serum at 4 immediately prior to injection. The number of cells (1 ?105 cells) to be injected was suspended in 0.1 ml PBS. The cells were were injected subcutaneously (into groin). The animals were sacrificed 4 weeks after injection. Pictures were recorded with a Nikon d800 digital camera (Nikon, Tokyo, Japan).Statistical analysisCell proliferation was measured by using the Cell Counting Kit-8 assay (CCK-8, Dojindo, Japan). Briefly, cells were plated into 96-well plates at a density of 104 cells/well with 100 L of culture medium. After adhesion the cells were incubated for 24, 48 and 72 h. At the end of each culture period, 10 L CCK-8 reagent was added to each well and incubated for another 4 h, then the absorbance was measured at 450 nm wavelength.EdU assayAll results were expressed as the mean ?s.d. The Student’s t-tests were used to analyse significant differences between samples. All the histogram was evaluated by performing GraphPad Prism, version 4.0 (GraphPad Software, San Diego California, USA). Statistical analyses were performed using Stata. 11.0. P <0.05 indicated statistically significant.ResultsER binds the MTA1 promoter and downregulates MTA1 expressionCells (2 ?103 cells/well) were seeded in triplicate in 96well plates and incubated overnight. Cells were starved in DMEM without FBS for 24 h and then incubated in DMEM containing 5 FBS. Then the EdU (5-ethynyl-Previous studies show that expression of MTA1 inversely correlates with ER nuclear localization [6]. We searchedDeng et al.
