Transcriptional regulation of the Drosophila catalase gene by the DRE/DREF system.
Reactive oxygen species (ROS) cause oxidative stress and aging. The catalase gene is a key component of the cellular antioxidant defense network. However, the molecular mechanisms that regulate catalase gene expression are poorly understood. In this study, we have identified a DNA replication-related element (DRE; 5'-TATCGATA) in the 5'-flanking region of the Drosophila catalase gene. Gel mobil...
متن کاملTranscriptional regulation of the Drosophila caudal homeobox gene by DRE/DREF.
The caudal-related homeobox transcription factors are required for the normal development and differentiation of intestinal cells. Recent reports indicate that misregulation of homeotic gene expression is associated with gastrointestinal cancer in mammals. However, the molecular mechanisms that regulate expression of the caudal-related homeobox genes are poorly understood. In this study, we hav...
متن کاملTranscriptional regulation of the Drosophila CycA gene by the DNA replication-related element (DRE) and DRE binding factor (DREF).
The Drosophila gene for cyclin A is expressed in dividing cells throughout development. This expression pattern is similar to those of genes related to DNA replication, suggesting involvement of some common control mechanism(s). In the upstream region (-71 to -64 with respect to the transcription initiation site) of the CycA gene, we found a sequence identical to the DNA replication-related ele...
متن کاملThe Hippo pathway as a target of the Drosophila DRE/DREF transcriptional regulatory pathway
The DRE/DREF transcriptional regulatory system has been demonstrated to activate a wide variety of genes with various functions. In Drosophila, the Hippo pathway is known to suppress cell proliferation by inducing apoptosis and cell cycle arrest through inactivation of Yorkie, a transcription co-activator. In the present study, we found that half dose reduction of the hippo (hpo) gene induces e...
متن کاملTranscriptional regulation of the Drosophila-raf proto-oncogene by the DNA replication-related element (DRE)/DRE-binding factor (DREF) system.
The DRE/DREF system plays an important role in transcription of DNA replication genes such as those encoding the 180 and 73 kDa subunits of DNA polymerase alpha as well as that for encoding PCNA. In this study, we found two sequences homologous to DRE (5'-TATCGATA-3') in the 5'-flanking region (-370 to -357 with respect to the transcription initiation site) of the D-raf gene and confirmed trans...
