Pressbox (Press Release) - A Histofine kit (Nichirei, Tokyo, Japan), using the streptavidin�Cbiotin amplification method, was used in this study. The antigen�Cantibody complex was visualized with 3,3��-diaminobenzidine (DAB) solution [1 mM DAB, 50 high throughput screening assay mM Tris-HCl buffer (pH 7.6) and 0.006% H2O2], and counterstained with hematoxylin. As a negative control, normal mouse or rabbit IgG was used instead of the primary antibodies, and no immunoreactivity was detected in these tissue sections. Immunoreactivity of RUNX2 and Ki67 was detected in the nuclei. Their immunoreactivity was evaluated in more than 1,000 carcinoma cells for each case, and subsequently, the percentage of immunoreactivity, that is, labeling index (LI), was determined. The status of ER�� immunoreactivity was evaluated using Allred score.19 Briefly, following an evaluation of the proportion (0: none, 1: <1/100, 2: 1/100�C1/10, 3: 1/10�C1/3, 4: 1/3�C2/3, and 5:>2/3) and immunointensity (0: none, 1: weak, 2: moderate, and 3: strong) in the carcinoma cells, oxyclozanide the total score more than 3 was considered ER��-positive case. An association between RUNX2 LI and clinicopathological factors of colon carcinoma patients was statistically evaluated using a correlation coefficient (r) and regression equation, Student's t test, or a one-way ANOVA and Bonferroni test. Overall survival curves were generated according to the Kaplan�CMeier method and the statistical significance was calculated using the log-rank test. Both univariate and multivariate analyses were performed by a proportional hazard model (COX) using StatView 5.0 software (SAS Institute, Cary, NC), and differences with p <0.05 were considered significant. Two human colon carcinoma cell lines (SW480 and DLD-1) were provided from the American Type Culture Collection (Manassas, VA). The cells were cultured in the recommended medium [L-15 Medium Leibovitz (Sigma-Aldrich, St. Louis, MO) selleck products for SW480 or RPMI1640 (Sigma-Aldrich) for DLD-1, containing 10% heat-inactivated fetal bovine serum (FBS; Sigma-Aldrich) and 1% penicillin�Cstreptomycin (Invitrogen, Carlsbad, CA)]. A pure ER antagonist ICI 182,78020 was purchased from Tocris Cookson (Ellisville, MO) in this study. Total RNA was extracted from cultured cells using the RNeasy Mini Kit (Qiagen, Valencia, CA). cDNA was synthesized using a SuperScript III First-Strand Synthesis System for reverse transcription-polymerase chain reaction Kit (Invitrogen) from 5 ��g of total RNA. The LightCycler System (Roche Diagnositics GmbH, Mannheim, Germany) was used to semiquantify the mRNA expression levels by real-time PCR.21 The primer sequences used in our study are as follows: RUNX2 (NM_004348 forward: 782�C800 and reverse: 943�C961),22 ER�� (AB006590; forward: 1,460�C1,480 and reverse: 1,608�C1,627), and ribosomal protein L 13a (RPL13A) (NM_012423; forward: 487�C509 and reverse: 588�C612).
