  • NOTE. One million mouse breast cancer 4T1 cells were inoculated on right flank of each mouse and considered as a high-risk group. Mice were sacrificed after 15 and 30 days of tumor cell inoculation and observations were recorded at the same time. Each treatment group has 10 mice.

    The data in parentheses indicate % inhibition by GTP treatment.
