Although this study did not reveal any dosage-sensitive interactions between the genes of interest, it did elucidate the importance of class IV da neuron morphology in promoting proper forager-to-wanderer transition as an over-branching phenotype correlated with an impairment of the transition. Furthermore, this study revealed that failure to undergo forager-to-wanderer transition is separable from mechanical nociception responses, which was surprising as both forager-to-wanderer transition and mechanical nociception responses are reliant on class IV da neurons.

In review. Ongoing Research Support 4T32 GM008056-34 Coller (PI) 05/01/2017 - Present Regulatory Role of Chromosome 11p13 in Cystic Fibrosis Lung Disease Severity The goal of this study is to elucidate the regulatory mechanisms by which the modifier region at 11p13 contributes to CF lung disease severity. More specifically, the goal of this study is to determine how potentially important cis-elements within the region work.
