Transforming growth factor β (TGF-β) is well known to play paradoxical roles in tumorigenesis as it has both growth-inhibitory and pro-metastatic effects. However, the underlying mechanisms of how TGF-β drives the opposing responses remain largely unknown. Here, we report that ERBB4, a member of the ERBB receptor tyrosine kinase family, specifically promotes TGF-β's metastatic response but not its anti-growth response.

The global pandemic caused by COVID-19 led to numerous novel cases of autoimmune and rheumatologic disorders that developed postinfection. Along these lines, these authors report an unusual case of scleredema following SARS-CoV-2 infection in an individual who lacked any known risk factors. Given the emergence of newer mutant strains of COVID-19 and steadily rising numbers of people receiving COVID-19 vaccinations, physicians should remain alert for as yet unrecognized manifestations of the disease.

TNFAIP3-interacting protein 1 (TNIP1; also known as ABIN-1) is a ubiquitin-binding protein that suppresses death-receptor- or Toll-like receptor-mediated apoptosis and necroptosis; however, it remains unclear whether ABIN-1 is capable of regulating pyroptosis. In the present study, we found that, in mouse embryonic fibroblasts and macrophages, ABIN-1 deficiency sensitized cells to poly(I:C) + TAK1 inhibitor 5Z-7-oxozeaenol-induced pyroptosis besides apoptosis and necroptosis. The sensitizing effect of ABIN-1 deficiency on pyroptosis depended on caspase-8 and its adaptor molecule FAS-associated death domain protein.

On Earth, iron is abundant, bioavailable, and crucial for initiating the first catalytic reactions of life from prokaryotes to plants to mammals. Iron-complexed proteins are critical to biological pathways and essential cellular functions. While it is well known that the regulation of iron is necessary for mammalian development, little is known about the timeline of how specific transcripts network and interact in response to cellular iron regulation to shape cell fate, function, and plasticity in the developing embryo and beyond.
