DNA damage induces downregulation of histone gene expression through the G1 checkpoint pathway

Su, Chuan, Gao, Guang, Schneider, Sandra, Helt, Christopher, Weiss, Carsten, O'Reilly, Michael A, ...

Activation of the G1 checkpoint following DNA damage leads to inhibition of cyclin E–Cdk2 and subsequent G1 arrest in higher eucaryotes. Little, however, is known about the molecular events...

DREF Is Required for Efficient Growth and Cell Cycle Progression in Drosophila Imaginal Discs

Hyun, Joogyung, Jasper, Heinrich, Bohmann, Dirk

Based on overexpression studies and target gene analyses, the transcription factor DNA replication-related element factor (DREF) has been proposed to regulate growth and replication in Drosophila...

Non-cell-autonomous induction of tissue overgrowth by JNK/Ras cooperation in a Drosophila tumor model

Uhlirova, Mirka, Jasper, Heinrich, Bohmann, Dirk

The role of c-Jun N-terminal kinase (JNK) signaling in cancer is enigmatic, and both tumor-promoting and tumor-suppressing functions have been ascribed to JNK pathway components. We have used the...

Drosophila Fos mediates ERK and JNK signals via distinct phosphorylation sites

Ciapponi, Laura, Jackson, David B., Mlodzik, Marek, Bohmann, Dirk

During Drosophila development Fos acts downstream from the JNK pathway. Here we show that it can also mediate ERK signaling in wing vein formation and photoreceptor differentiation. Drosophila JNK...
