ME1 is a direct L-lactate sensor that connects #Lactate signaling with HDGF-associated EMT and ME1–LDHB-mediated metabolic adaptation, shaping tumor plasticity across heterogeneous metabolic conditions.

Sharing a visualization from our ongoing modeling work on intratumoral oxygen dynamics and the HIF-1α-driven transcriptional response. Figure: "Oxygen tension collapse drives coordinated hypoxia-angiogenesis program across the tumor radius" Subtitle: "Simulated intratumoral pO₂ gradient from vessel wall to necrotic core with HIF-target activation" The figure uses a horizon-style stacked area representation (layered oxygen-gradient contour strip) to render pO₂ as a function of radial distance from the perfused vessel wall toward the necrotic core. Each contour band encodes a discrete oxygen tension interval, with marker overlays indicating the activation thresholds of canonical HIF-1α target loci. I want to emphasize that the underlying data are simulated; the parameterization reflects diffusion-limited oxygen distributions consistent with published Krogh-cylinder estimates and the well-characterized ~100–200 µm diffusion limit. The central observation is the coordinated character of the transcriptional program along the radial axis. Proximal to the vessel wall, pO₂ remains above the threshold for prolyl hydroxylase domain (PHD/EGLN) activity, sustaining VHL-mediated HIF-1α degradation. As oxygen tension declines toward the intermediate perinecrotic zone, PHD activity becomes substrate-limited, HIF-1α escapes hydroxylation and proteasomal turnover, and it accumulates to drive HRE-dependent transcription. The marker overlays illustrate the staggered engagement of glycolytic effectors (SLC2A1, LDHA), pH-regulatory targets (CA9), and pro-angiogenic signaling (VEGFA) as the gradient steepens. The horizon-strip format was chosen deliberately to compress the steep radial pO₂ decay into a legible vertical encoding while preserving the coincidence between tension thresholds and target activation.

... what if we could also map how cells use energy and nutrients within a tumour?

🔐 This information has remained inaccessible until now, but it could be key to understanding the metabolic strategies that support tumour growth
