Proteins were transferred to poly(vinylidene difluoride) and probed with antibodies against phospho-p38 MAP kinase (Thr-180/Tyr-182), phospho-p44/42 MAP kinase (Thr-202/Tyr-204), and phospho-c-Jun (Ser-63) (Cell Signaling Technology). MAP kinases. Simultaneous loss of GR and other nuclear receptor activities could render an animal more susceptible to lethal or toxic effects of anthrax infection by removing the normally protective antiinflammatory effects of these hormones, similar to the increased mortality seen ENMD-2076 Tartrate in animals exposed to both ENMD-2076 Tartrate GR antagonists and infectious agents or bacterial products. These finding have implications for development of new treatments and prevention of the toxic effects of anthrax. Death from anthrax toxin is reported to result from systemic shock (1) resembling lipopolysaccharide (LPS)-induced shock (2, 3) although the role of inflammatory cytokines in this process and the precise mechanism of this shock have not been determined (4). Anthrax toxin is composed of three proteins: protective antigen (PA), edema…

g, qRT-PCR analysis of the indicated ISGs in MC-38 cells treated with 3 M mitochondria-targeted doxorubicin (mitoDox) or DMSO (Mock) for 48 hours. mtDNA are present in most cell types that are packaged by TFAM into higher-order structures called nucleoids1. Mitochondria are also platforms for antiviral signalling2 and, due to their bacterial origin, mtDNA and other mitochondrial components trigger innate immune responses and inflammatory pathology2,3. We showed previously that instability and cytoplasmic release of mtDNA activates the cGAS-STING-TBK1 pathway resulting in interferon stimulated gene (ISG) expression that promotes antiviral immunity4. Here, Methylthioadenosine we find that prolonged mtDNA stress is not associated with basally activated NF-B signalling or interferon gene expression typical of an acute antiviral response. Instead, a specific subset of ISGs, that includes mice exposed to ionizing radiation exhibit enhanced repair responses in spleen nDNA. Therefore, we suggest that harm to and following launch of mtDNA elicits a protecting…
