Highly responsive single-fluorophoreindicator to explore lactate dynamics in high calcium environments

A. Galaz, P. Y. Sandoval, I. Soto, H. Hertenstein, J. Schweizer, S. Schirmeier, L. F. Barros, A. San Martin

The paper develops a single-fluorophore lactate indicator, CanlonicSF, suitable for high Ca2+ environments, showing improved sensitivity and specificity over existing FRET-based indicators.

Temperature, but not excess of glycogen, regulate post-mortem AMPK activity in muscle of steer carcasses.

P. Strobel, A. Galaz, F. Villaroel-Espindola, A. Apaoblaza, J. C. Slebe, N. Jerez-Timaure, C. Gallo, A. Ramirez-Reveco

This study shows that post-mortem AMPK activity in steer muscle is significantly influenced by temperature but not by glycogen concentration.

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.
