Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Aquaporin‐1, aquaporin‐3 and aquaporin‐5 differentially modulate cell biophysical and biomechanical properties, impacting cell stiffness and cell–cell adhesion

The FEBS Journal, EarlyView.
GA text Overexpression of aquaporins AQP1, AQP3, or AQP5 in HEK‐293 T cells induced changes in cell biophysical properties and migration. Atomic force microscopy (AFM)–based force spectroscopy studies demonstrated that AQP1 overexpression increased cell stiffness and cell–cell adhesion, AQP3 augmented cell stiffness but reduced cell–cell adhesion ...

The fc fragment of IgMs binds C1q to activate the first step of the classical complement pathway, while inhibiting complement‐dependent cytotoxicity

The FEBS Journal, EarlyView.
Multimeric IgM‐fragment crystallizable region (Fc) fragments retain the ability to bind C1q and initiate the classical complement pathway, leading to C4 activation and deposition in vitro. However, the Fc cores can also inhibit complement‐dependent cytotoxicity by competing with surface‐bound antibodies for C1q engagement.

Moderate increase of MET in hepatocytes protects against cholestatic liver injury by promoting an effective antioxidant response

The FEBS Journal, EarlyView.
Moderate overexpression of wild‐type Met in hepatocytes (Alb‐R26Met mouse model) boosts a strong antioxidant response dependent on the glutathione system while impairing TGF‐β signaling in the liver. This leads to improved liver regeneration and protects against DDC‐induced injury, a model for cholestatic disease sharing features with primary ...
