TABLE 3

Log of normalized ratios for metallopeptidases in oropharyngeal and kidney tissues

The relative gene expressions vs. controls of mAPP and NEP are normalized to GAPDH. Average ratios (n = 6) are expressed as mean ± S.D. Values are log means ± S.D. Only tissues with significant differences are shown (p < 0.05).
