Figure Lengend Snippet: Reporter luciferase-based one-cycle infection inhibition assay. MDCK cells growing in 96-well plates were infected with reporter influenza PR8-PB2-Gluc virus at an MOI of 0.1, in the absence or presence of increasing concentrations of (A) CHLA and (B) CHLI. Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 4% fetal bovine serum (FBS) were used as culture medium during infection to avoid generation of infectious progeny viruses. At 24 h post infection (p.i.), Gluc expression was determined, and viral infectivities were evaluated. Data are means ± SD from three independent experiments. * p

Figure Lengend Snippet: TCDD suppresses colony formation in RKO human colorectal cancer cells in vitro . Cells (1×10 3 cells/well) were seeded into 6-well plates and cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum, 1% penicillin/streptomycin and 1% fungizone in the presence of vehicle (1% dimethyl sulfoxide) or TCDD (1 or 10 nM) for 5 days when visible clones formed. The colonies were washed with PBS, fixed with methanol and then stained with 0.5% crystal violet. (A) Stained cells are presented as images (×10), and (B) the colonies containing > 50 cells were counted under a microscope. * P

Figure Lengend Snippet: TCDD suppresses the proliferation of RKO human colorectal cancer cells in vitro . The cells (1×10 5 cells/well in 24-well plates) were cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum, 1% penicillin/streptomycin and 1% fungizone in the presence of vehicle (1% dimethyl sulfoxide) or TCDD (0.01-100 nM) for (A) 3 or (B) 7 days. After culture, the numbers of attached cells were counted. Data are presented as mean ± standard deviation obtained from 8 wells of 2 replicate plates per dataset using different dishes and cell preparations. * P

Figure Lengend Snippet: The TCDD-induced increase in CYP1A1 levels are suppressed in the regucalcin-overexpressing RKO human colorectal cancer cells in vitro . The wild-type RKO cells or regucalcin-overexpressing transfectants (1×10 6 cells/dish) were cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum, 1% penicillin/streptomycin and 1% fungizone in the presence or absence of vehicle (1% dimethyl sulfoxide) or TCDD (10 nM) for 3 days and then cell lysates were centrifuged. Subsequently, 40 µ g of the supernatant protein per lane were separated by SDS-PAGE and transferred to nylon membranes for western blotting using specific antibodies against the indicated proteins. Representative data from three independent experiments using different cell preparations are presented, and data are presented as mean ± standard deviation. (A) Representative film images of the TCDD effect. (B) Presented relative to β-actin of the TCDD effect. * P

Cell lysates were prepared and centrifuged, and 40 µ g of the supernatant protein per lane were separated by SDS-PAGE and transferred to nylon membranes for western blotting using specific antibodies against various proteins as indicated. Data represent a typical figure of three independent experiments using different cell preparations, and also are presented as mean ± standard deviation.
