This article makes a valuable contribution to the field by uncovering a molecular mechanism for miRNA intracellular retention, mediated by the interaction of PCBP2, SYNCRIP, and specific miRNA motifs.

Scientists have studied a new target for antibiotics in the greatest detail yet—in the fight against antibiotic resistance.

Stress triggers the body’s fight-or-flight response. Chronic stress can cause negative health effects on your mood, immune and digestive systems, and cardiovascular health. You’re sitting in ...

Anaerobes respire extracellular electron acceptors by extracellular electron transfer (EET). It is widely recognized that flavins can act as electron shuttles to facilitate this process. Flavin ...

Polymyxin B nonapeptide (PMBN), a cationic cyclic peptide derived by enzymatic processing from the naturally occurring peptide polymyxin B, is able to increase the permeability of the outer membrane ...

Small, hydrophilic molecules, including most important antibiotics in clinical use, cross the Gram-negative outer membrane through the water-filled channels provided by porins. We have determined the ...
