- P. pacificus : Dauers and Dauer-Exit at 12 hour time-point vs. Mix-stage worms
Transcriptional profiling of P. pacificus worms from (1) dauer stage, or (2) dauer-exit at 12 hours stage, compared to mix-stage worms as a common reference. The goal was to determine genes regulated during dauer development and recovery or exit from dauer stage. This data was then compared to data generated for corresponding developmental stages in the C. elegans (see NCBI GEO series GSE30977) , to study evolution of developmental pathways regulating dauer development.

Onchocerca volvulus is a filarial nematode parasite of humans, causing Onchocerciasis, or River Blindness, which affects over 37 million people, mainly in Africa. It is a severely debilitating disease, which is transmitted to humans by black fly. This project aims to undertake high-throughput sequencing of Onchocerca volvulus transcriptome for de novo assembly of transcripts. The main objective of this project is to recognize genes expressed in given life stages. This data is part of a pre-publication release.

- Regulation of signaling genes by TGFbeta during entry into dauer diapause in C. elegans
BACKGROUND: When resources are scant, C. elegans larvae arrest as long-lived dauers under the control of insulin/IGF- and TGFbeta-related signaling pathways. : We have identified genes that show different levels of expression in a comparison of wild-type L2 or L3 larvae (non-dauer) to TGFbeta mutants at similar developmental stages undergoing dauer formation. Many insulin/IGF pathway and other known dauer regulatory genes have changes in expression that suggest strong positive feedback by the TGFbeta pathway. In addition, many insulin-like ligand and novel genes with similarity to the extracellular domain of insulin/IGF receptors have altered expression. We have identified a large group of regulated genes with putative binding sites for the FOXO transcription factor, DAF-16. Genes with DAF-16 sites upstream of the transcription start site tend to be upregulated, whereas genes with DAF-16 sites downstream of the coding region tend to be downregulated. Finally, we also see strong regulation of many novel hedgehog- and patched-related genes, hormone biosynthetic genes, cell cycle genes, and other regulatory genes.
