In Vitro and In Vivo Anticancer Effects of Sterol Fraction from Red Algae Porphyra dentata

Figure 8

Arginase activity of MDSCs in naive mice, tumor-bearing control mice, and tumor-bearing mice treated with P. dentata F2 fraction. The splenic MDSCs were isolated from various groups of BALB/c mice and were lysed for 10 min in the lysis buffer and the arginase activity (shown as urea production) in the cell lysate was measured, as described in Section 2. Data were obtained from one experiment, with 3 mice from each group, and expressed as mean ± S.D.
