Regulation of segment polarity genes in the head region of different arthropods
Head segmentation in insects, as reflected by the model system Drosophila melanogaster, is less well understood in comparison to the trunk. While the gnathal segments (mandibular, maxillary, labial) are patterned in a way similar to the trunk, distinct molecular mechanisms underlie the …

Patterning the Drosophila Embryonic Central Nervous System: Establishing Neuroblast-Specific Gene Expression and Identity
… based on their position in the embryo, the genes they express, and the number and type of neuronal progeny they produce. A fundamental problem in the development of any animal is how to generate cell diversity. Studying the mechanisms of neuroblast differentiation will help to understand …

INVESTIGATING PAIR-RULE GENE ORTHOLOGS IN AN INTERMEDIATE GERM BEETLE, DERMESTES MACULATUS
Insects share a body plan based on repeating segments. Segmentation has been well characterized in Drosophila melanogaster, in which segments are established by a genetic hierarchy including gap, pair-rule and segment polarity genes. Pair-rule genes (PRGs) are a key class of segmentation genes as …

Algorithms for modeling and simulation of biological systems; applications to gene regulatory networks
… are explored via an artificial network of the segment polarity genes in the D. melanogaster. Once a mathematical model has been built, it can be used to run simulations of the biological system under study. Comparison of simulated dynamics with experimental measurements can help refine the …
