Effects of high-Pi diet at 2 wk on the liver of developing mice. Two-week-old transgenic mice were fed a normal- or high-Pi diet for 2 wk. A: liver mass as a percentage of body mass. B: luciferase activities were measured for the determination of the ratios between cap-dependent and cap-independent protein translations in the liver. C: expression of PCNA, FGF-2, MMP-2, CD31, and CD34 proteins in the liver. D: bands of interest were further analyzed by densitometry. *P < 0.05, compared with normal diet group (means ± SE, n = 5).
