The study investigates how chronic hypoxia affects mENT1, the primary adenosine transporter in cardiomyocytes. It focuses on the regulatory role of PKC in this process.
HL-1 cardiomyocyte cells were exposed to hypoxia (2% O2) for 0-20 hours.
Various assays were performed including cell viability, LDH release, glucose uptake, and mENT1 mRNA level measurements.
PKC activity was assessed using phorbol ester treatment and a dominant negative PKC construct.
Hypoxia (8-20 h) significantly down-regulates mENT1-dependent adenosine uptake and NBTI-binding in HL-1 cells.
Chronic hypoxia decreases mENT1 mRNA after 4 hours, returning to basal levels by 20 hours.
PKC activity inhibition replicates the hypoxia-induced effects on adenosine uptake, indicating its regulatory role.
