Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Alternative transcription cycle for bacterial RNA polymerase
In the canonical bacterial transcription, both nascent transcript and polymerase dissociate from template DNA. By employing multi-color single-molecule fluorescence imaging, here the authors show that RNA polymerases remain bound to DNA after the ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

APEX2 proximity labeling of RNA in bacteria
Summary: Rapid, spatially controlled methods are needed to investigate RNA localization in bacterial cells. APEX2 proximity labeling was shown to be adaptable to rapid RNA labeling in eukaryotic cells and, through the fusion of APEX2 to different ...

An RNA Surprise in Bacterial Effector Mechanisms [PDF]
Bacterial pathogens secrete effector proteins to manipulate host signaling proteins and cellular structures. In this issue of Cell Host & Microbe, Pagliuso et al. (2019) propose an effector mechanism in Listeria monocytogenes whereby an RNA-binding protein associates with bacterial RNA that stimulates RIG-I (retinoic acid inducible gene I)-based innate

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Single-Cell RNA Sequencing of Plant-Associated Bacterial Communities
Plants in soil are not solitary, hence continually interact with and obtain benefits from a community of microbes (“microbiome”). The meta-functional output from the microbiome results from complex interactions among the different community members with ...

PANoptosis in the pathogenesis of myelodysplastic syndromes
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Purification of Bacterial RNA from Infected Macrophages
Studying the transcriptome of bacterial pathogens during infection is a very informative and effective tool for discovering genes that contribute to successful infection.
