    A. Western blot analysis of nuclear extracts from Raw264.7. After pre-incubation with N. vitripennis venom (5 µg/ml) for 15 minutes, cells were induced for the indicated times with LPS (1 µg/ml). Subsequently, nuclear extracts were subjected to Western blot analysis to determine p65 levels. Separation of nuclear and cytoplasmic fractions was verified using PARP as control for the nuclear fractions. B. After 15 minutes pre-incubation with N. vitripennis venom, cells were induced for the indicated times with LPS (1 µg/ml). Immunofluorescence staining was performed to visualize the trafficking of the p65 subunit. Representative results from three separate experiments are shown.

    TNF stimulation leads to activation of the canonical NF-κB signal transduction pathway marked by IκBα degradation and translocation of the p65-p50 dimer to the nucleus. Subsequent NF-κB DNA binding enables transcription of different genes, among which the cytokine IL-6. Venom treatment leads to the inhibition of TNF induced IL-6 gene expression. In addition, TNF activates the MAPKs,JNK, ERK1/2 and p38, and pretreatment with venom results in prolonged JNK activation. The negative NF-κB regulators A20 and IκBα are indicated and both were suppressed by the venom. Glucocorticoid binding to the cytosolic Glucocorticoid Receptor (GR) results in the dissociation of chaperoning proteins, followed by GR translocation to the nucleus, where it can interfere with the activity of NF-κB. Activated GR can also directly bind to the DNA, stimulating transcription of FKBP5, MKP1 and GILZ target genes. Only the two latter genes are transcriptionally induced by the venom. The red arrows mark the various levels at which venom of N. vitripennis interferes with the represented cellular signaling pathways.

    TNF stimulation leads to activation of the canonical NF-κB signal transduction pathway marked by IκBα degradation and translocation of the p65-p50 dimer to the nucleus. Subsequent NF-κB DNA binding enables transcription of different genes, among which the cytokine IL-6. Venom treatment leads to the inhibition of TNF induced IL-6 gene expression. In addition, TNF activates the MAPKs,JNK, ERK1/2 and p38, and pretreatment with venom results in prolonged JNK activation. The negative NF-κB regulators A20 and IκBα are indicated and both were suppressed by the venom. Glucocorticoid binding to the cytosolic Glucocorticoid Receptor (GR) results in the dissociation of chaperoning proteins, followed by GR translocation to the nucleus, where it can interfere with the activity of NF-κB. Activated GR can also directly bind to the DNA, stimulating transcription of FKBP5, MKP1 and GILZ target genes. Only the two latter genes are transcriptionally induced by the venom. The red arrows mark the various levels at which venom of N. vitripennis interferes with the represented cellular signaling pathways.

    Cr(VI) caused intracellular Ca 2+ overload and NF- κ B activation. The L02 hepatocytes were exposed to Cr(VI) for 4 weeks. (a) The mean fluorescence intensity intracellular Ca 2+ concentration was determined by light microscopy (the micrograph of the cells, 200x), and ImageJ software was used to analyze the relative fluorescent intensity showed in bar graph; (b) spectrofluorometry was used to detect the change of Ca 2+ concentration in cytoplasm. (c) Rhod-2 was used to assay the concentration of Ca 2+ in mitochondria. (d) The protein levels of p65 (cytoplasm and nucleus) were determined by Western blot. (e) The expression of I κ B α and IKK α was detected by Western blot after Cr(VI) treatment. ImageJ software was used to analyze the relative levels of proteins normalized to the expression of GAPDH. All experiments were repeated at least 3 times and expressed as mean ± SD. ∗ p < 0.05, compared with control. For the sake of clarity, the same control GAPDH was applied to compare with all experimentally relevant proteins with the same exposure time detected on the same SDS-PAGE gel unless otherwise stated.
