Figure Lengend Snippet: rADAM9D promotes DU145 cell adhesion. Collagen type I (Col.I), collagen type IV (Col.IV), laminin, fibronectin (10 µg) (positive controls) or different quantities of ADAM9D (5, 10 and 50μg) were immobilized in the wells of a 96-well plate in adhesion buffer at 4°C. After blocking with 1% BSA (negative control), CMFDA-labeled DU145 cells (1 × 105 cells/well) were seeded in the wells. The plates were incubated at 37 °C for 30 min, washed, lysed and read for the release of fluorescence. BSA was used as negative control for cell adhesion. The results were obtained from 3 independent experiments in triplicate. The means that are significantly different from those of cells growing on collagen using ANOVA followed by post hoc Dunnett's test were shown by *(P ≤ 0.001). The results were normalized by the collagen type I values in each experiment. The error bars show the SE of three samples with less deviation from the mean.

Cells were washed and incubated with secondary antibody labeled with FITC, at same conditions described before, washed and fixed with FACs buffer contaning 1% phormaldehyde overnight at 4°C. C. To verify the interaction with integrins, rADAM9D (1 µM) was previously incubated (30 min at room temperature) with DU145 cells, before the addition of antibodies. Cells were analyzed in FACSCanto. The results were obtained from 3 independent experiments in triplicate. The error bars show the SE of three samples with less deviation from the mean.

doi: 10.4161/19336918.2014.994917

Figure Lengend Snippet: rADAM9D inhibits the migration of DU145 cells in a wound healing assay. (A) Cells (1 × 105 cells/ml) were plated in 24-wells plates and incubated properly until the culture reached 100% of confluence. Afterwards, a straight scratch was made with a pipette tip and cells were washed with culture medium to remove unbound cells and debris. Cells were incubated with ADAM9D (100, 500, 1000 and 2000 nM) for 24 h and 48 h. Only pictures from rADAMD9 500 and 2000 nM are represented. Central field was photographed at 0h, 24 h and 48 h (when cells close the scratch completely). (B) Closure area of migrating cells was measure using ImageJ software, and it was calculated the percentage of wound closure, comparing time zero and 24 hour. Results are expressed as percent of wound closure relative to control (untreated) cells. The results were obtained from 3 independent experiments in triplicate. The error bars show the SE of three samples with less deviation from the mean. The means that are significantly different from the control using ANOVA followed by post hoc Dunnett's test: *(P ≤ 0.05), **(P ≤ 0.01) and ***(P ≤ 0.001).

Article Snippet: Cell line and culture DU145 human prostate tumor cell line was obtained from ATCC and maintained at 37°C in 5% CO 2 in RPMI culture medium (Cultilab) containing 10% FBS, penicillin (100 UI/ml), streptomycin (100 μg/ml) and L-glutamine (2mM).

Article Title: N-Cadherin Expression in Human Prostate Carcinoma Cell Lines

doi:

Figure Lengend Snippet: Photomicrographs of tumors of the prostate carcinoma cell lines PC-3N (A) and DU-145 (B) on the surface of diaphragms of SCID mice. SCID mice (n = 4) were injected intraperitoneally with 5 × 10 5 cells, sacrificed 5 weeks after injection, and the diaphragms fixed and processed in paraffin. DU145 tumors have penetrated the basement membrane, and PC-3N have penetrated through the murine straited muscle. Five-micron sections were cut and deparaffinized for hematoxylin and eosin staining. Scale, 60 μm.
