    <p>(A)Western blot showing Flag-MageA11 when co-expressed with increasing quantities of HA-MageA6 (0, 250, 500, 1000 and 1500 ng). GFP expression is the internal control. Membrane was probed with the indicated antibodies. (B) Western blot showing Flag-MageA11 when co-expressed with increasing quantities of HA-MHD-MageA6 (0, 250, 500, 1000 and 1500 ng). GFP expression is the internal control. Membrane was probed with the indicated antibodies. (C) Western blot showing Flag-MageA11 when co-expressed with increasing quantities of HA-MageA2 (0, 250, 500, 1000 and 1500 ng). GFP expression is the internal control. Membrane was probed with the indicated antibodies. (D) Western blot of LNCaP cells silenced (siA6/2) or not (siC) for MageA6 expression. Anti-pan MAGE-A antibody (6C1, Santa Cruz) was used to detect Mage-A proteins. 65KDa band corresponds to MageA11 while 45KDa band could correspond to different Mage-A proteins. GAPDH was used as loading control. (E)Left panel: Western Blot showing the endogenous levels of MageA11 in LNCaP stably expressing MageA6 (A6) or empty vector (EV). Extracts of HEK293T cells transfected with Flag-MageA11 (F-A11), HA-MageA6 (HA-A6) or empty vector (EV) were used as controls. MAGE-A detection was performed with anti-pan MAGE antibody (6C1, Santa Cruz). 65KDa band corresponds to MageA11 while 45KDa band could correspond to different Mage-A proteins. The observed increment in 45KDa band in LNCaP-A6 is caused by MageA6 stable expression. Right panel: quantification of MAGE-A11 vs β-tubulin band intensity corresponding to Fig 4E, lanes 4 and 5. (F) RT-qPCR for the determination of MageA11 mRNA levels in LNCaP-A6 (A6) and LNCaP-EV (EV). MageA11 mRNA was normalized to GAPDH mRNA levels. (G) RT-qPCR for the determination of PSA mRNA levels in LNCaP-A6 (A6) and LNCaP-EV (EV). PSA mRNA was normalized to GAPDH mRNA levels. Error bars indicate mean S.D. Student’s t test was used for statistical analysis. ** p < 0.001. * unspecific band. Triangles show the corresponding protein band and dashes mark the MW.</p

    <p>Analysis of cBioPortal Cancer Genomics data sets form Prostate Adenocarcinoma and Testicular Germ Cell Cancer (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0178370#sec002" target="_blank">Material and Methods</a>) as indicated in the two main columns. Gene overexpression was calculated by Z-score, defined as the relative expression of an individual gene to the gene’s expression distribution in a reference population. The indicated percent of over-expression refers to the number of samples over-expressing a given gene over the total of samples. Dot-plot graphics shows the correlation between MageA6 and MageA11 gene expression. Insets indicate Pearson and Spearman correlation scores.</p

    <p>(A) Reporter gene assay for GR, MR and AR activity using specific gene-reporter in the presence or absence of MageA6 or MageA11 expression. Cells were treated with dexamethasone (Dx), Aldosterone (Aldo) or dihidrotestosterone (DHT) for 24 h prior to harvesting. The assay was performed in HEK293T cells. ev, empty vector. (B) Similar to A but combining MageA11 and MageA6 expression as indicated. (C) Determination of PSA mRNA levels through RT-qPCR. LNCaP cells were transfected with a siRNA control (siC) or a siRNA to silence MageA6 expression (siA6/2). DHT was added to cells as indicated. PSA mRNA levels were normalized to GAPDH mRNA levels. Error bars indicate mean S.D. Student’s t test was used for statistical analysis. * p < 0.05. ** p < 0.001.</p

    <p>(A)Western blot showing Flag-MageA11 alone or when co-expressed with HA-MageA6 after 0, 3 and 6 hours of cycloheximide (CHX) treatment. The membrane was probed with the indicated antibodies. (B) Western blot showing Flag-MageA11 expression in the presence of MG132 (1,5uM for 20h) or absence of MG132 (DMSO) after 0, 2, 4 and 6 hours of cycloheximide (CHX) treatment. The membrane was probed with the indicated antibodies. (C) Western blot showing Flag-MageA11 levels alone or when co-expressed with HA-MageA6 in the presence of MG132 or absence of MG132 (DMSO). GFP expression is the internal control. Membrane was probed with the indicated antibodies. *Unspecific band. Triangles show the corresponding protein band and dashes mark the MW.</p

    <p>(A) Kaplan–Meier survival curve of time to distant metastasis of breast cancer patients classified according to the expression of GTSE1. Red line: cases with high expression of GTSE1, blue line: cases with low expression of GTSE1. (p-value <10?–15) (B) Boxplots of the distribution of gene expression intensities of GTSE1 across different breast cancer subtypes (Grade 1, 2 or 3; p<10?-5; linear regression analysis),. (C) Western blot analysis of GTSE1 and EB1 protein levels in different breast cancer cell lines. Tumor types are: F, fibrocystic disease, non-transformed, immortal cell line; IDC, invasive ductal carcinoma; AC, adenocarcinoma; MC, metaplastic carcinoma. Invasive potential is characterized as not invasive (−), invasive (+), or highly invasive (++). Adapted from Neve et al. Cancer Cell 2006. (D) Quantitative RT-PCR analysis of GTSE1 and EB1 relative mRNA levels in MCF7 and MDA-MB-231 cells. Error bars represent the standard error of the mean from three independent experiments. p<0.01 (Student’s t-test). (E) Transwell migration assay and western blot of the MDA-MB-231 cell line. Cells were transfected with control (CON) or GTSE1 siRNA for 36 hours, trypsinized, and seeded on transwell membranes. Histograms show the mean number of cells/area that migrated through the transwell after 16 h (10 replicates/experiment). Error bars represent the standard error of the mean from three independent experiments. * indicates p<0.05 (Student’s t-test). Western blots were performed on cells after the same treatment, and blotted with anti-GTSE1 and anti-actin. (F) Transwell migration assay and western blot of the MCF7 cell line containing a stably integrated GTSE1 overexpression construct (pBABE-GTSE1) or empty vector (pBABE). Cells were trypsinized and seeded on transwell membranes. Histograms show the mean number of cells/area that migrated through the transwell after 16 h (10 replicates/experiment). Western blots were performed on cells after the same treatment, and blotted with anti-GTSE1 and anti-actin.</p
