1 They are also cross-resistant to hydroxyurea and guanazole, and studies on enzyme activity levels support our previous findings with cells selected for resistance to hydroxyurea, which showed changes in CDP reductase activity are not always coordinated with changes in ADP reductase. Hydroxyurea cut like homeobox 1 Homo sapiens
2 Moreover, increases in cellular resistance were accompanied by significant increases in CDP but not ADP reductase, suggesting that an ability to maintain an adequate level of CDP reductase activity is especially important to achieve resistance to DNA synthesis inhibitors like N-carbamoyloxyurea, hydroxyurea, and guanazole. carbamoyloxyurea cut like homeobox 1 Homo sapiens
3 Moreover, increases in cellular resistance were accompanied by significant increases in CDP but not ADP reductase, suggesting that an ability to maintain an adequate level of CDP reductase activity is especially important to achieve resistance to DNA synthesis inhibitors like N-carbamoyloxyurea, hydroxyurea, and guanazole. Hydroxyurea cut like homeobox 1 Homo sapiens
