(Submitter supplied) In fasted mammals, glucose homeostasis is maintained through activation of the cAMP responsive CREB coactivator TORC2, which stimulates the gluconeogenic program in concert with the forkhead transcription factor FOXO1. Here we show that starvation also triggers TORC activation in Drosophila, where it maintains energy balance by promoting the expression of CREB target genes in the brain. TORC mutant flies have reduced glycogen and lipid stores, and they are sensitive to starvation as well as oxidative stress. more...

(Submitter supplied) Purpose: Exploring the alteration in CREB/CRTC binding related to long-term memory Methods: The nuclei of Drosophila mushroom bodies were purified and the histone acetylation and CREB/CRTC binding were examined by ChIP-seq using specific antibodies. The sequencing was performed using Miseq, and aligned to dm3 using CLCbio. The sequence reads that passed quality filters were analyzed by peak calling using PICS and ERD equipped on Strand NGS software. more...

(Submitter supplied) Differential expression analysis used the DESeq2 Bioconductor package, a model based on the negative binomial distribution. the estimates of dispersion and logarithmic fold changes incorporate data-driven prior distributions, Padj of genes were setted <0.05 to detect differential expressed ones.Our study represents the detailed analysis of of NP1 and NP1/CRTCHA drosophila gut transcriptomes, with biologic replicates, generated by RNA-seq technology.Transcriptome analysis indicated that the genes involved in proteasome assembly, ROS scavengers, and protein folding were highly enriched among those differentially expressed genes (DEGs) in CRTC overexpressing (CRTCOE) intestines.
