Core Binding Factors (CBFs) are members of a small family of transcription factors that play critical roles in a number of mammalian developmental processes. CBFs are heterodimers consisting of a CBFα subunit, which contacts and binds DNA at the...
Many environmental toxicants found in pesticides, herbicides, and industrial solvents are believed to have deleterious effects on development by disrupting hormone-sensitive processes. Xenopus embryos were exposed to commonly encountered endocrine...
Drosophila. Photoreceptors. TRP channels. Cellular signal transduction.
The phototransduction cascade in Drosophila is a prototypical G-protein signaling pathway and many of its components have been well-studied. Early genetic screens identified many of the major proteins involved in this pathway and study over the...

Mutations in the Drosophila retinal-specific Phospholipase C (NORPA) cause massive retinal degeneration within five days of constant light exposure. We have previously shown that in norpA mutants persistent complexes between the light receptor...
This thesis describes the synthetic study of two biologically related natural products: porphobilinogen (PBG) and cobyric acid. PBG is the key intermediate in the biosynthesis of all naturally occurring tetrapyrrolic 'pigments of life', including...
RUNX1 is a transcription factor regulating hematopoietic development. Study of the RUNX1 structure revealed two functional domains. The runt domain binds DNA and mediates interaction with CBFß. Sequences C terminal to the runt domain form the...
Core binding factors are heterodimeric transcription factors involved in diverse developmental processes. They consist of a DNA binding Runx subunit and a non-DNA binding CBFβ sub-unit. Runx proteins are encoded by three genes: Runx1, Runx2 , and...
Most of the cells that die during the development of a C. elegans hermaphrodite do so within 30 min after being generated. In these cells, the pro-caspase proCED-3 is inherited from progenitors and the transcriptional upregulation of the BH3-only...

Cellular signal transduction.
In humans, progressive loss of vision accompanies many inherited retinal degenerative disorders. In many cases, the affected genes are known. However the molecular pathway of photoreceptor cell death is still elusive. In this thesis, I describe the...
Something must bear the load of poleward forces exerted by kinetochore-associated motors so that chromosomes move toward the poles rather than the poles towards the chromosomes. I tested this hypothesis by monitoring chromosome movement in cultured...
