Figure 6. Hypoxia increases reductive carboxylation in pulmonary artery smooth muscle cells.

Figure 6.

(A) Reductive carboxylation describes the converstion of α-ketoglutarate (AKG) to isocitrate by reverse flux through isocitrate dehydrogenase (IDH) (blue arrow). This yields M+5 citrate. (B) Exchange flux estimates for reductive carboxylation. Data show the model estimate with upper and lower bounds for LFs and PASMCs.
