1/For over a decade, we’ve been studying tumor metabolism in patients with non-small cell lung cancer

This long-term commitment allowed us to connect tumor metabolic features to patient outcomes

We found that 13C glucose contribution to the TCA cycle predicts overall survival in NSCLC

A study reveals complete glycolysis inside mitochondria, crucial for function. Confirmed by CoIP-MS and [U-¹³C] tracing; key in Retinitis Pigmentosa's pathogenesis. Insightful data!

Intra-mitochondrial glycolysis maintains mitochondrial function and underlies the pathogenesis of retinitis pigmentosa | Nature Communications
Glycolysis is classically defined as a cytoplasmic process. Here, in our investigation of mitochondrial dysfunction in Retinitis Pigmentosa (RP), we report the unexpected discovery of a complete and functional glycolytic pathway operating inside mitochondria. Through CoIP-MS, polysome profiling, and [U-13C] glucose isotope tracing, we demonstrate that key glycolytic enzymes are locally translated and metabolically active within the organelle. Mechanistically, we show that the VWA8-PHB2-GRP75 complex is responsible for anchoring these enzymes, thereby sustaining intra-mitochondrial glycolysis and preserving mitochondrial function by regulating NAD+ levels and reactive oxygen species (ROS) homeostasis. In vivo, Vwa8 knockout in both mice and zebrafish abolishes this metabolic safeguard, leading to RP-like phenotypes that can be partially rescued by reactivating mitochondrial glycolysis. Collectively, these findings redefine the spatial compartmentalization of glucose metabolism and estab

2/ We use intra-operative infusions of 13C-labeled nutrients, like glucose, to study tumors

We’ve learned a lot with this approach. We saw that tumor metabolism can be very heterogeneous and that tumors use a variety of nutrients. Even so-called “waste” products are recycled by lung tumors.
