Article Title: Mouse Norovirus infection arrests host cell translation uncoupled from the stress granule-PKR-eIF2α axis
doi: 10.1101/536052
Figure Lengend Snippet: (A) BMMs were uninfected, uninfected and NaAs treated (250 μM for 20 mins) or MNV-infected (MOI 5) for 12 hrs. The WB was immunolabelled with anti-NS7, anti-p-eIF2α and anti-eIF2α antibodies (B) Immunoblot analysis of uninfected, uninfected and NaAs treated (250 μM for 20 mins) or MNV-infected (MOI 5) cell lysates harvested at 3, 6, 9 and 12 h.p.i. The WB was immunolabelled with anti-NS7, anti-p-eIF2α and anti-actin antibodies. (C and D) BMM cells were either infected with MNV (MOI 5) or left uninfected and analysed for their translation using puromycin (10 μg/mL). ( C ) Immunoblot analysis of puromycin-treated (20 mins) cell lysates harvested at 3, 6, 9, 12 and 15 h.p.i. The WB was immunolabelled with anti-puromycin, anti-NS7, anti-p-eIF2α and anti-actin antibodies. ( D ) IF analysis of puromycin treated (10 μg/ml for 30 mins) cells at 6, 9 and 12 hrs post infection. Cells were stained with anti-puromycin, anti-NS5 and DAPI for the merged image. Stars indicate uninfected cells displaying high signal for anti-puromycin. Samples were analysed via the Zeiss LSM 710 confocal microscope and analysed with the ZEN software.
Article Snippet: Rabbit anti-eIF2α was purchased from Invitrogen; Rabbit anti-actin from Sigma-Aldrich; Mouse anti-puromycin from Kerafast Inc; Mouse anti-G3BP1, Mouse anti-GAPDH, Rabbit anti-HIS and Rabbit anti-calnexin from Abcam and Rabbit anti-p-eIF2α (S52) and Alexa Fluor-conjugated species-specific IgG were purchased from Life Technologies.
