Transmission electron microscopy revealed viral factories (viral collections forming vesicular structures), at various stages of development. Immunogold staining against viral capsid σ-1 protein demonstrated viral "homing" in the tumor cells. The nucleus displayed sufficient euchromatin regions suggestive of active transcription. Flow cytometry revealed rapid dendritic cell maturation (48 hours) with subsequent activation of cytotoxic T cells (7 days). CONCLUSIONS The combination of pelareorep with FOLFIRI/bevacizumab is safe. The PFS and OS data are encouraging and deserve further exploration. Pelareorep leads to a clear recurrent immune stimulatory response with cytotoxic T cell activation, and homes and replicates in the tumor.

They argue that in important healthcare settings (such as distributing vital organs for dying patients), the state should treat people on the basis of their chronological age because chronological age is a better proxy for what matters from the point of view of justice than adjusted official age. While adjusted legal age should not be used in deciding who gets scarce vital organs, I remind the readers that using chronological age as a proxy is problematic as well. Using age as a proxy could give wrong results and it is better, if possible, for states to use the vital information directly than use age as a proxy. © Author(s) (or their employer(s)) 2020.

ASK1-3 form oligomeric complexes known as ASK signalosomes that initiate signaling cascades in response to diverse stress stimuli. Here, we demonstrated that oligomerization of ASK proteins is driven by previously uncharacterized sterile-alpha motif (SAM) domains that reside at the carboxy-terminus of each ASK protein. SAM domains from ASK1-3 exhibited distinct behaviors, with the SAM domain of ASK1 forming unstable oligomers, that of ASK2 remaining predominantly monomeric, and that of ASK3 forming a stable oligomer even at a low concentration. In contrast to their behavior in isolation, the ASK1 and ASK2 SAM domains preferentially formed a stable heterocomplex. The crystal structure of the ASK3 SAM domain, small-angle x-ray scattering, and mutagenesis suggested that ASK3 oligomers and ASK1-ASK2 complexes formed discrete, quasi-helical rings through interactions between the mid-loop of one molecule and the end helix of another molecule. Q-VD-Oph cell line Preferential ASK1-ASK2 binding was consistent with mass spectrometry showing that full-length ASK1 formed hetero-oligomeric complexes incorporating large amounts of ASK2. Accordingly, disrupting the association between SAM domains impaired ASK activity in the context of electrophilic stress induced by 4-hydroxy-2-nonenal (HNE). These findings provide a structural template for how ASK proteins assemble foci that drive inflammatory signaling and reinforce the notion that strategies to target ASK proteins should consider the concerted actions of multiple ASK family members.

Here, we found that mortalin depletion was selectively lethal to tumor and immortalized normal cells expressing the mutant kinase B-RafV600E or the chimeric protein ΔRaf-1ER and
