PC were enrolled and fresh biopsy tissues were then analyzed. Controls AGI-5198 included fresh normal nasopharyngeal mucosal tissues from patient biopsies for other non-neoplastic diseases. The collection of NPC specimens 10463589 target=’resource_window’>1963850 and clinical and pathological information were reviewed and approved by the human research committees of the Chang Gung Memorial Hospital and the written informed consents were obtained from each patient involved prior to this study commencing. Clinicopathological information for each subject, including gender, age, tumor- stage, nodal- status, distant metastasis, TNM stage, and overall survival, was obtained retrospectively from clinical records and pathology reports. NPC patients received local head and neck examinations before treatment, along with staging examinations, including whole body bone scans, abdominal ultrasonography, computed tomography, and/or magnetic resonance imaging. Using the 2010 American Joint Committee on Cancer system, 26 patients were classified as T1, 30 as T2, 4 as T3, and 24 as T4. Thirty patients were classified as N0, 20 as N1, 27 as N2, and 7 as N3. Seventy-five patients were classified as M0 and 9 as M1. Twelve patients were determined to be in stage I, with 22 in stage II, 18 in stage III, and 32 in stage IV. The method of radiotherapy was, in general, uniform within this period of time. All patients were regularly monitored after radiotherapy and/or chemotherapy until death or their last appointment, according to the intervals and protocols of follow-up detailed in a previous study. Survival data was obtained from the cancer registry of our hospital or collected from the patients’ attending physicians. Locoregional failure was determined by pathological diagnosis or progressive deterioration, as demonstrated by consecutive imaging studies. To identify distant metastases, patients underwent chest radiography yearly and bone scan or abdominal ultrasonography when indicated. RNA Extraction and Quantitative RT-PCR Tissue samples were frozen in liquid nitrogen and stored at -80C prior to RNA extraction. RNA extraction and quantitative RT-PCR assays were performed as described previously. Fibulin-5 and FLJ10540 Taq-Man probes were used for Q-RT-PCR. Data are presented as means SD. To analyze the distribution of normal and tumor areas, we used the Wilcoxon signed-rank test between 2 groups for statistical analysis. A P-value of <0.05 was considered to be statistically significant. GAPDH was used as an internal control for 2 Fibulin-5-Elicits NPC Motility by AKT Pathway comparison and normalization. Assays were performed in triplicate on an Applied Biosystems 7500 Fast instrument. Immunoblot analysis For protein extraction, frozen samples were homogenized in RIPA lysis buffer. Western blotting was performed as described previously. Antibodies included against fibulin-5, FLJ10540 , DDK, phosphor-AKT and AKT, lamin A/C, and actin were applied. The proteins were investigated using X-ray films. were purchased from Gibco-BRL. TW01 cells were grown in DMEM; Hone1 cells were grown in RPMI containing 10% FBS and 100 U/mL penicillin and streptomycin. DDK-vector and DDK-fibulin-5 were transiently transfected into cancer cells using Lipofectamine based on the manufacturer's instructions. Mixed TW01 and Hone1 cells stably expressing fibulin-5 were selected with 400 g/mL G418 for 2 weeks. The cells were then harvested and analyzed for exogenous fibulin-5 expression by Western blotting.
