Figure 4. Cellular bioenergetics measured by flux analysis of irradiated parental and NS subcultures of U251 and A172 cells.

Figure 4

Comparison of oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) using an extracellular flux analyzer before and after irradiation. To facilitate comparisons between cells treatments and measurements, the OCR and ECAR levels of U251 controls were set to unity. Error bars correspond to the SD of triplicate measurements. Significance between unirradiated controls for each triplicate data set (asterisks above individual bars) and between parental and NS subcultures (asterisks above brackets) are shown.
