Expression data from HeLa cells treated with V-ATPase inhibitors or with desoxyferramine compared to HeLa treated with DMSO or medium with low LDL To determine which genes respond first to low concentrations of V-ATPase inhibition, we treated HeLa cells with two different V-ATPase inhibitors, bafil...

Synaptic vesicles are organelles with a precisely defined protein and lipid composition, yet the molecular mechanisms for the biogenesis of synaptic vesicles are mainly unknown. Here, we discovered a well-defined interface between the synaptic vesicle V-ATPase and synaptophysin by in situ cryo-elect...

V-ATPase-dependent induction of selective autophagy
Yeast vacuoles, equivalent to lysosomes in other eukaryotes, are important acidic degradative organelles as well as storage compartments and signaling hubs. To perform these functions, they rely on important protein complexes, including the V-ATPase, responsible for organelle acidification. In this ...

V-ATPase-Driven Lysosomal Activation Orchestrates MEK2-Induced Endothelial Reprogramming
Defects in organellar acidification indicate compromised or infected compartments. Recruitment of the autophagy-related ATG16L1 complex to pathologically de-acidified compartments targets ubiquitin-like ATG8 molecules to perturbed membranes. How this process is coupled to pH gradient disruption is u...

Human naïve pluripotent stem cells (nPSCs) can differentiate into trophectoderm (TE) and self-organize into embryo-like structures known as blastoids, typically requiring complex cocktails of signaling factors. Here, we demonstrate that dimethyl sulfoxide (DMSO) alone robustly induces TE differentia...

A reversible broad-spectrum antiviral targets the human V-ATPase VO domain
Lithocholic acid (LCA), accumulated in mammals during calorie restriction (CR), can activate AMP-activated protein kinase (AMPK) and slow down ageing1. However, how LCA is signalled to activate AMPK and elicit the biological effects is unclear. Here, we show that LCA can enhance the activity of sirt...

The general consensus is that the vacuolar-type H+-translocating ATPase (V-ATPase) is critical for macroautophagy/autophagy. However, there is a fundamental conundrum because follicular lymphoma-associated mutations in the V-ATPase result in lysosomal/vacuolar deacidification but elevated autophagy ...
