- Identification of an upstream regulatory element reveals a novel requirement for Ind activity in maintaining ind expressionTonia L Von Ohlen
Division of Biology, Kansas State University, 116 Ackert Hall, Manhattan, KS 66506, USA
Mech Dev 124:230-6. 2007..We conclude that Ind can act as a transcriptional activator, and that positive autoregulation of Ind is a mechanism for persistent ind expression within the developing embryonic nervous system...
- Identification of Ind transcription activation and repression domains required for dorsoventral patterning of the CNSTonia L Von Ohlen
Division of Biology, Kansas State University, Manhattan, KS 66506, USA
Mech Dev 126:552-62. 2009..Second, we show that Ind can and does repress vnd expression, but does so in a stage specific manner. We conclude from this that the function of Ind in regulating vnd expression is one of refinement and maintenance of the dorsal border...
- Ind represses msh expression in the intermediate column of the Drosophila neuroectoderm, through direct interaction with upstream regulatory DNATonia Von Ohlen
Division of Biology, Kansas State University, Manhattan, Kansas 66506, USA
Dev Dyn 238:2735-44. 2009..Specifically, expression is expanded ventrally in ind mutant embryos and Ind protein directly and specifically bound to the msh regulatory DNA, and this interaction was required to limit the ventral boundary of msh expression...
