Reactive oxygen species, redox signaling and neuroinflammation in Alzheimer's disease: the NF-κB connection.
Oxidative stress and inflammatory response are important elements of Alzheimer's disease (AD) pathogenesis, but the role of redox signaling cascade and its cross-talk with inflammatory mediators have not been elucidated in details in this disorder. The review summarizes the facts about redox-signaling cascade in the cells operating through an array of kinases, phosphatases and transcription factors and their downstream components. The biology of NF-κB and its activation by reactive oxygen species (ROS) and proinflammatory cytokines in the pathogenesis of AD have been specially highlighted citing evidence both from post-mortem studies in AD brain and experimental research in animal or cell-based models of AD. The possibility of identifying new disease-modifying drugs for AD targeting NF-κBsignaling cascade has been discussed in the end.

[Anti-tumor effect of tanshinone II A, tetrandrine, honokiol, curcumin, oridonin and paeonol on leukemia cell lines].
To study the anti-tumor effect of tanshinon II A, tetrandrine, honokiol, curcumin, oridonin and paeonol on leukemia cell lines SUP-B15, K562, CEM, HL-60 and NB4.. To study the anti-tumor effect of tanshinone II A, tetrandrine, honokiol, curcumin, The leukemia cell lines were exposed to the six Chinese herbal components for 96 hours. The proliferative inhibitory effects were detected with MTT and described by IC50 value.. Tanshinone II A inhibited the proliferations of SUP-B15, K562, CEM, HL-60 and NB4 cell lines, with HL-60 showing the least impact. Tetrandrine, honokiol, curcumin and oridonin inhibited the proliferations of SUP-B15, K562, CEM, HL-60 and NB4 cell lines and there was no significant difference between the cell lines. Paeonol did not have significant inhibitory effect on leukemia cell lines.. Tetrandrine, honokiol, curcumin and oridonin inhibit the proliferation of five cell lines SUP-B15, K562, CEM, HL-60, NB4, and the effects are similar, which means that their anticancer effects are quite broad. Tanshinone II A has better anti-leukemia effects on SUP-B15, K562, CEM, NB4 than on HL-60. The effect of paeonol against leukemia cell lines is poor.

Sensitization to TRAIL-induced apoptosis in human neuroblastoma SK-N-AS cells by NF-κB inhibitors is dependent on reactive oxygen species (ROS).
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been shown to induce apoptosis in a variety of cancer cell lines with almost no toxicity toward normal cells. However, many neuroblastoma cells acquire resistance to TRAIL by mechanisms that are poorly understood. The objective of this study was to investigate involvement of the transcription factor NF-κB in the resistance of human neuroblastoma SK-N-AS cells to TRAIL-induced apoptosis. We used five compounds previously reported to inhibit NF-κB activity. SN50, curcumin, oridonin, and pyrrolidine dithiocarbamate (PDTC) all sensitized cells to TRAIL-induced apoptosis. In contrast, N-alpha-tosyl-L: -phenylalanyl chloromethyl ketone (TPCK) did not affect sensitivity to TRAIL, although reporter gene assay clearly showed inhibition of NF-κB activity. In addition, neither curcumin nor oridonin had any inhibitory effect on NF-κB activity at concentrations at which sensitization to TRAIL was observed. Instead, the free radical scavenger N-acetyl-L: -cysteine (NAC) completely blocked the effect on TRAIL-induced apoptosis caused by curcumin, oridonin, and PDTC. Furthermore, exposure of SK-N-AS cells to H(2)O(2) could mimic the TRAIL-sensitizing effect of other agents. In conclusion, our results suggest that sensitization of neuroblastoma SK-N-AS cells to TRAIL-induced apoptosis is correlated with induction of reactive oxygen species (ROS) rather than inhibition of NF-κB.
