Method for identifying agents which modulate cell growth or survival
View Patent ↗The present invention relates to a method for identifying an agent. for modulating cell growth or survival. The method involves the identification of an agent which modulates the net ratio of nuclear-localized versus cytosolic-localized H11 kinase or mutant H11 kinase in a cell. A method for diagnosing a cancer associated with H11 kinase or Akt activation in a subject is also provided.
1. A method for identifying an agent for increasing cardiac cell survival comprising:
a) contacting a first cardiac cell containing H11 kinase with a test agent;
b) determining the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in said first cell;
c) determining the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in a second cardiac cell that has not been contacted with said test agent; and
d) comparing the difference between the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in the first cell as compared with the second cell wherein an increase in said ratio in the first cell as compared to the ratio in the second cell indicates that the test agent increases cardiac cell survival.
2. A method for identifying an agent for increasing cardiac cell survival comprising:
a) contacting a first cardiac cell containing H11 kinase encoded by the nucleic acid of
SEQ ID NO:2 or 3 with a test agent;
b) determining the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in said first cell;
c) determining the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in a second cardiac cell that has not been contacted with said test agent; and
comparing the difference between the net ratio of nuclear-localized versus cytosolic-localized H11 kinase in the first cell as compared with the second cell, wherein an increase in said ratio in the first cell as compared to the ratio in the second cell indicates that the test agent increases cardiac cell survival.
