| pubmed-article:4016772 | pubmed:abstractText | The stability of the P388 mouse leukemia model over 15 years was examined. Eleven natural products and one synthetic compound (5-FU) tested repetitively under the same conditions of dose and schedule were associated with no significant change in their activity. The P388 model, used in conjunction with other in vivo and in vitro tumor models, continues to be of value in the anticancer drug screening process. | lld:pubmed |
