| abstractText | To elucidate the role of nitric oxide (NO) in tumor cell growth in vivo, dynamic aspects of the growth of Ehrlich ascites tumor cells (EATCs) were studied in wild-type (WT) mice and in an inducible strain of NO synthase (iNOS)-deficient (iNOS(-/-)) mice. Kinetic analysis showed that the rate of free tumor cell growth in the peritoneal cavity was significantly higher in the iNOS(-/-) mice than in the WT mice. In contrast, EATCs inoculated subcutaneously rapidly grew and formed a solid tumor in WT mice, but failed to grow in iNOS(-/-) mice. These results clearly indicate that NO generated by iNOS predominantly inhibits the growth of tumor cells in their free form, but enhances the growth of solid tumors. |
