A highly responsive pyruvate sensor reveals pathway-regulatory role of the mitochondrial pyruvate carrier MPC

R. Arce-Molina, F. Cortes-Molina, P. Y. Sandoval, A. Galaz, K. Alegria, S. Schirmeier, L. F. Barros, A. San Martin

The paper introduces PyronicSF, a GFP-based sensor for real-time mitochondrial pyruvate transport, concentration, and flux, revealing the MPC's role in regulating respiration vs. anaplerosis/gluconeogenesis.

MCT4 is a high affinity transporter capable of exporting lactate in high-lactate environments

Y. Contreras-Baeza, P. Y. Sandoval, R. Alarcon, A. Galaz, F. Cortes-Molina, K. Alegria, F. Baeza-Lehnert, R. Arce-Molina, A. Guequen, C. A. Flores, A. A. San Martin, L. F. Barros

The paper revises the kinetic properties of MCT4, showing it has high lactate affinity and can extrude lactate in high-lactate environments, challenging previous pH probe-based estimates.
