Reduction/oxidation disorder is one of the most common ailments in HIV-infected patients, and such patients are frequently left exposed to chronic oxidative stress after the generation of reactive oxygen species (ROS). Although a variety of clinical trials to inhibit HIV infection have been conducted by focusing on oxidative stress, their precise targets(More)
The activation of NF-kappaB by neutrophil lactoferrin (Lf) is regulated via the IkappaB kinase (IKK) signaling cascade, resulting in the sequential phosphorylation and degradation of IkappaB. In this study, we observed that Lf protein augmented p65 phosphorylation at the Ser(536), but not the Ser(276) residue, and stimulated the translocation of p65 into(More)
The cell proliferation of p53-deficient Jurkat T cells is controlled after prolonged exposure to human lactoferrin (Lf). However, the molecular mechanism by which Lf influences these cellular responses remains unclear. In this study, we demonstrate that Lf-induced apoptosis in Jurkat T cells occurs in a dose- and time-dependent manner via the regulation of(More)
The vaccinia virus (VV) replicates robustly and alters the progression of the cell cycle via an unknown mechanism. Herein, we provide evidence for the existence of a unique VV infection-induced cell cycle control mechanism. The regulation is correlated with the inactivation of p53 and Rb, which are associated with the RNA polymerase III transcription factor(More)
