Figure 6. Inhibition of CA9 and CA12 in rat NP cells leads to reduced OCR without affecting mitochondrial respiration or functional activity.
A–C) OCR was reduced in rat NP cells treated with MZA (500 nM) (A), AZA (100 nM, 500 nM) (B) and U-104 (500 nM, 2 μM) (C) before and after treatment with antimycin A. D) Treatment of rat NP cells with MZA, AZA, and U-104 significantly decreased average OCR. E) Treatment of rat NP cells with MZA, AZA, and U-104 has no effect on mitochondrial OCR. F) Rat NP cells treated with MZA, AZA, and U-104 showed no change in their mitochondrial oxidoreductase activity, implying preservation of mitochondrial function. All quantitative data is represented as mean ± SE, n=3 independent biological replicates with 4 technical replicates per biological replicate, p<0.05.
