Uptake of adenosine 5'-monophosphate by Escherichia coli [PDF]

Journal of Bacteriology, 1975
Adenosine 5'-monophosphate is dephosphorylated before its uptake by cells of Escherichia coli. This is demonstrated by using a radioactive double-labeled culture, and with a 5'-nucleotidase-deficient, mutant strain. The adenosine formed is further phosphorolyzed to adenine as a prerequisite for its uptake and incorporation. The cellular localization of

Bioengineering a Patient‐Derived Vascularized Lung Tumor‐on‐Chip Model to Decipher Immunomodulation by the Endothelium

Advanced Healthcare Materials, EarlyView.
Most in vitro cancer models lack cellular diversity, functional complexity, and clinical relevance. This work highlights the generation of an innovative dynamic tetraculture with autologous patient‐derived cells within a vascularized tumor‐on‐chip, as well as the recapitulation of endothelial anergy features induced by the tumor microenvironment ...

Emodin Alleviates Sepsis‐Induced Multiorgan Damage by Inhibiting NETosis through Targeting Neutrophils BCL‐10

Advanced Science, EarlyView.
Emodin targets BCL‐10 to modulate the BCL‐10/MALT1 complex, thereby suppressing NF‐κB activation and significantly exerting multiorgan protective effects in sepsis. Abstract Sepsis is a life‐threatening condition caused by dysregulated host responses to infection, characterized by excessive inflammation and abnormal coagulation.

Dopamine D1 Receptor Contributes to Glucocorticoid‐Associated Osteonecrosis of Femoral Head Protection Through the ATF3/CHOP Axis to Inhibit Osteoblastic Apoptosis

Advanced Science, EarlyView.
This work identifies a novel mechanism by which dopamine D1 receptor (DRD1) contributes to the pathogenesis of glucocorticoid (GC)‐associated osteonecrosis of the femoral head (ONFH) through the regulation of osteoblastic apoptosis, indicating that DRD1 serves as a critical mediator of the crosstalk between the nervous and skeletal systems.
