GAST and infection: Additional genes of interest included Dicer-2 (suggesting transcriptional crosstalk between immune signaling pathways and the siRNA pathway), a putative neuropeptide with a conserved gastrin/cholecystokinin site (possibly mediating an anorexic response to infection), an arrestin, GPRDIH1 (a GPCR involved in diuretic hormone signaling), and an ortholog of the D. melanogaster transcription factor Wbp2 (a partner of yorkie in the hippo pathway).
