Antiviral

Cells were stimulated with TPA (10 nM) for 15 min in the presence of the indicated concentrations of U0126. Samples were collected and analyzed by Western blot to detect phosphorylated p42/p44 MAPK.

(B and C) sh-scrambled or sh-ck2a–transducted L929 cells (B) and Raw cells (C) were stimulated by DMXAA (100 μg/ml) for various times. Cytosolic and nuclear extracts were prepared as described in Materials and Methods. Five percent of the cytosolic proteins and 20% of the nuclear proteins were resolved by 10% SDS-PAGE. Subsequently, immunoblotting was conducted by indicated Abs. The amounts of Tubulin and Lamin B1 in cytosol versus nuclei detected by respective Abs were used as internal control for fractionation.

Phenotypic effect of Genetic or Pharmacologic Compromise of the 477 Hsp70-StiA-Hsp90 Complex. The impact of each genetic modification on radial growth, conidiation, and response to various stress conditions was assessed after inoculation of a suspension of 104 conidia on glucose minimal medium (GMM) agar plates and incubation at 37ºC for 5 days.

The Nucleotide analog reverse-transcriptase inhibitor Tenofovir disoproxil fumarate was added to TZM-bl cells. Cells were inoculated with 0.05 ng mock-exposed and semen-exposed HIV, and 0.5 ng HIV as infectivity-matched control. Infection rates were measured 3 days post infection by measuring β-galactosidase or or 4 days post infection by measuring luciferase activities. The left panels show the mean enzyme activities ± standard deviation derived from triplicate infections. RLU/s: relative light units per second. Middle panels show normalized infection rates in which reporter enzyme activities obtained from infected cells in the absence of inhibitor were set at 100%. The right panels depict the calculated IC50 values. The number above the bar represents the fold-change in the IC50 derived from 0.05 ng semen-exposed relative to 0.05 or 0.5 ng mock-exposed virus infection. Ns, no statistically significant difference; **** p<0.0001; *** p<0.001 (unpaired t-test).

(C) Double immunolabeling showed CK-labeled cells (green) co-expressed with 40, 6-diamidino-2-phenylindole (DAPI) (blue), scale bars are 50 μm.

Verification of Hdac6 deletion in knockout MEFs. Expression of HDAC6 and acetylation of tubulin were analyzed by immunoblotting.

(E) Left panel, Western blot showed that 20 μM Ribavirin effectively inhibits elevated Sox2 expression in irradiated SW1990 cells. Right panel, qPCR analysis showed that Sox2 mRNA level in irradiated SW1990 cells at 48 hours was lower than that in non-irradiated SW1990 cells, *p < 0.05. (F) Left panel, Western blot showed 20 μM Ribavirin inhibits elevated Sox2 expression in irradiated BxPc-3 cells. Right panel, qPCR analysis showed that there is no significant fluctuation of Sox2 mRNA in irradiated BxPc-3 cells and Ribavirin did not influence sox2 mRNA level in irradiated BxPc-3 cells.

(A) HONE1 and (B) HK1-EBV cells were treated with TPA (40 ng/ml) and SB (3 mM) for EBV induction. After 3 h, uninduced and induced HONE1 and HK1-EBV cells were treated with the vehicle control (0.006% DMSO) or indicated concentrations of berberine for 48 h. Subsequently, the culture medium was harvested for quantitative-PCR analysis with EBNA1 primers. Each sample was normalized to the amount of the GAPDH gene; *p<0.05, compared with the control group.
