Figure Lengend Snippet: Embryonated chicken eggs (ECE) (A) , chicken embryo fibroblasts (CEF) (B) , baby hamster kidney cells (BHK-21) (C) , or bovine kidney cells (MDBK) (D) were infected with rNDV or rNDV_G RABV (moi 0.01). Allantoic fluids and cell culture supernatants were harvested at indicated time points after infection (p. i.). Viral titers (TCID 50 /mL) were determined after titration on quail muscle (QM9) cells and subsequent immunostaining. Bar charts depict mean viral titers standard deviation ((A) n = 4, four eggs from one experiment; (B, C, D) n = 4, two samples each from two independent experiments). Asterisks indicate significant differences of mean viral titer (α = 0.05).

Article Snippet: Primary chicken embryo fibroblasts (CEF) were prepared from 10-day-old specific pathogen free (SPF) embryonated chicken eggs (ECE), purchased from Valo, BioMedia (Osterholz-Scharmbeck, Germany) and incubated at 37° with 55% humidity.

Article Title: Immune response after oral immunization of goats and foxes with an NDV vectored rabies vaccine candidate

doi: 10.1371/journal.pntd.0011639

Figure Lengend Snippet: Chicken embryo fibroblasts (DF-1) (A) , bovine kidney cells (MDBK) and baby hamster kidney cells (BHK-21) (B) were infected with rNDV or rNDV_G RABV (multiplicity of infection (moi) 5) and harvested 24 h post infection (p. i.). Cell lysates and lysates of purified virions (10 μg per lane) (C) were subjected to SDS-PAGE and subsequently to Western blot analysis. Viral proteins were visualized by immunostaining with respective antibodies. Β-Actin was detected on every cell lysate blot as loading control. Blots of cell lysates are representative of three biological replicates. Blot of purified virions were done once. Uncompartmentalized illustrations can be found in the supporting information .

Article Title: Targeting STAT3 enhances NDV‐induced immunogenic cell death in prostate cancer cells

doi: 10.1111/jcmm.15089

Figure Lengend Snippet: Apoptosis and immunogenic cell death were induced by NDV/FMW in prostate cancer cells. A, DU145 and PC‐3 cells were infected with 0.01 MOI NDV/FMW for 24, 48 and 72 h, viral yield was determined at the indicated times by diluting serially in DF1 cells. Values are mean ± SD from three independent tests. B, DU145 and PC‐3 cells were mock‐infected or infected with NDV/FMW (MOI = 1) for 12, 24 and 48 h. Cell viablity were assessed by the CCK‐8 assay. Values are mean ± SD. (n = 3, *** P < .001). C, Cells were treated the same as in (B). Cell death was quantified by trypan blue staining. Values are mean ± SD (n = 3, *** P < .001, n.s = not significant). D, DU145 and PC‐3 cells were mock‐infected or infected with 1 MOI NDV/FMW for 24 and 48 h. Apoptosis was determined by flow cytometry. The group of cells in Annexin V‐positive with PI‐negative quadrant and Annexin V/PI positive quadrant are illustrated. The data displayed are representative of three independent tests (* P < .05; ** P < .01 and *** P < .001). E, DU145 and PC‐3 cells were treated the same as in (B). IB was used to determine the expression of the cleaved‐PARP, Beclin‐1, p‐eIF2α and haemagglutinin‐neuraminidase (HN) protein. Using β‐actin as a loading control. Protein intensity was quantified with Image Lab and shown in the histogram. All IB experiments were made three times. F, DU145 and PC‐3 cells were mock‐infected or infected with 10 MOI NDV/FMW for 12, 24 and 48 h, cell‐free supernatants (concentrated) and whole cell lysates were collected for IB analysis of HMGB1 and HSP70/90. G, DU145 and PC‐3 cells were treated the same as in (B), and cell‐free supernatants were collected to measure the amounts of HMGB1 using an enzyme‐linked immunosorbent (ELISA) detection. Existing data are mean ± SD (n = 3, n.s = not significant, *** P < .01). (H) DU145 and PC‐3 cells were treated the same as in (D), extracellular ATP in cell‐free supernatants was evaluated by ATP estimation. Existing data are mean ± SD calculated from three independent experiments (* P < 0.05; ** P < .01, n.s = not significant). I, DU145 and PC‐3 cells were treated the same as in (D). The cells were assessed by immunofluorescence staining and analysed under a confocal laser‐scanning microscope. Mitoxantrine (MTX), an ICD inducer, was used as a positive control. Nucleus was stained by DAPI. NDV/FMW was detected based on HN protein. The fluorescence intensity was semi‐quantitatively determined by Image J, and the results were expressed by mean density (n = 3, * P < .05; *** P < .001, ns = not significant)
