| abstractText | Mice lacking both c-Jun-NH(2)-terminal kinases (JNK1 and JNK2) were generated to define their roles in development. Jnk1/jnk2 double mutant fetuses die around embryonic day 11 (E11) and were found to display an open neural tube (exencephaly) at the hindbrain level with reduced apoptosis in the hindbrain neuroepithelium at E9.25. In contrast, a dramatic increase in cell death was observed one day later at E10.5 in both the hindbrain and forebrain regions. Moreover, about 25% of jnk1-/-jnk2+/- fetuses display exencephaly probably due to reduced levels of JNK proteins, whereas jnk1+/-jnk2-/- mice are viable. These results assign both pro- and anti-apoptotic functions for JNK1 and JNK2 in the development of the fetal brain. |
