Figure Lengend Snippet: Effects of PDGF-BB on the migration of AsPC-1 and BxPC-3 pancreatic cancer cells, compared with normal PE cells. (A) AsPC-1, (B) BxPC-3 and (C) PE cells (5×104 cells/well) were treated with the indicated doses of arsenite for 24 h, prior to be seeded in the upper Boyden chamber. Following incubation for 16 h, cells were exposed to 30 ng/ml PDGF-BB for 36 h at 37°C. Cells were then fixed, stained and visualized under a microscope. The average number of migrated cells from five randomly selected fields on the lower surface of the membrane was counted. Data were obtained from ≥3 independent experiments. *P<0.05 vs. controls. Right panels show representative images of the migrated cells stained with clonogenic reagent. PDGF, platelet-derived growth factor; PE, pancreatic epithelial.

Figure Lengend Snippet: Effects of arsenite on PARP cleavage in AsPC-1, BxPC-3 and PE cells. (A) AsPC-1, (B) BxPC-3 and (C) PE cells were exposed to arsenite (30 µM) for the indicated time periods. Protein extracts were then harvested and examined by western blotting using anti-PARP and anti-glyceraldehyde-3-phosphate dehydrogenase antibodies. Background-subtracted signal intensity of each protein band was normalized to GAPDH. Data are presented as the mean ± standard deviation of triplicate assay. *P<0.05. PARP, poly(adenosine diphosphate-ribose) polymerase; PE, pancreatic epithelial; GAPDH, glyceraldehyde-3-phosphate dehydrogenase.

Figure Lengend Snippet: Effects of arsenite on the phosphorylation of p44/p42 MAPK and Akt in AsPC-1, BxPC-3 and PE cells. (A) AsPC-1, (B) BxPC-3 and (C) PE cells were exposed to arsenite (30 µM) and incubated with 30 ng/ml platelet-derived growth factor-BB for the indicated time periods. Protein extracts were then harvested and examined by western blotting using specific antibodies against phospho-p44/p42 MAPK, p44/p42 MAPK, phospho-Akt and Akt. Background-subtracted signal intensity of each protein band was normalized to Akt. Data are presented as the mean ± standard deviation of triplicate assay. *P<0.05 vs. cells without arsenite exposure. PE, pancreatic epithelial; PDGF, platelet-derived growth factor; phospho, phosphorylated; MAPK, mitogen-activated protein kinase; M, marker.

Figure Lengend Snippet: Effect of SFN on BEAC cell survival. BEAC cells were cultured in the medium containing no SFN or various concentrations of SFN. Cells were harvested at different time points as indicated and proliferative potential was assessed by trypan blue exclusion and/or proliferation assay, based on the production of a yellow product (formazan) after reduction of a highly water-soluble tetrazolium salt by dehydrogenases in viable cells. The growth curves show the mean of three independent experiments, with SEM. (A) Barrett adenocarcinoma (FLO-1) cells treated with various concentrations of SFN. (B) BEAC (OE33) cells treated with various concentrations of SFN. (C) Photomicrograph of BEAC (FLO-1 and OE33) cells treated with 3 µM SFN for 72 hours. (D) Photomicrograph of normal diploid fibroblasts and primary normal esophageal epithelial cells (ScienCell Research Laboratories) treated with 3 µM SFN for 72 hours. (E) FLO-1 cells were treated with SFN for 48 hours, detached floating cells from the medium and the attached cells (by trypsinization) were collected separately and evaluated for number and viability using trypan blue exclusion. The number of cells detached after treatment with various concentrations of SFN is expressed as percent of untreated FLO-1 cells. “Total” represents the total number of detached cells whereas “Dead” reflects the fraction of dead cells in detached cell population. (F) Panel (I): FLO-1 cells were incubated with various concentrations of SFN for 48 hours, and the expression of caspase 8 was detected by Western blot analysis, using anti-caspase 8 mouse monoclonal antibody (Cell Signaling, Danvers, MA). Panel (II): Bar graph showing caspase 8 expression relative to β-actin.
