The in vivo effect of RFB4-RTA
peptides. (A) SCID mice with human xenografts were injected
with 200 μg of RFB4-dgRTA (□), RFB4-LDV+
(⊠), RFB4-GQT (▨), or saline (■), and
the wet/dry weight ratios of the human skin were determined.
(B) SCID mice were injected as described in A
and the wet/dry weight ratios of lungs were determined. Values
represent the mean of three experiments ± SD. Asterisks indicate
a significant difference from saline-treated mice (∗,
P < 0.02; ∗∗, P <
0.01).
