Action of alpha-momorcharin, a ribosome inactivating protein, on cultured tumor cell lines.
1. alpha-Momorcharin, a glycoprotein isolated from seeds of the bitter gourd, Momordica charantia inhibited incorporation of [3H]thymidine, [3H]leucine and [3H]uridine into P388 (mouse monocyte-macrophage), J774 (Balb/c macrophage), JAR (human placental choriocarcinoma) and sarcoma S180 cell lines. 2. The most potent inhibitory effect was exerted on P388 cells and the smallest effect on sarcoma cells. 3. alpha-Momorcharin also enhanced the tumoricidal effect of mouse macrophages on mouse mastocytomal (P815) cells.
