↵* P < 0.09 vs. contralateral tissue.
↵† P < 0.005 vs. contralateral tissue.
↵‡ P < 0.05 vs. deoxyglucose tumor-to-tissue ratio.
↵§ Data are from rats implanted with C6 tumors.
Data are mean ± SD (C6 tumors: n = 6 for glucose use, n = 7 for acetate uptake; U-373 tumors: n = 4 per group for glucose use and acetate uptake).
