Description
RNA sequencing was used to identify genome wide transcriptional changes occurring in the Drosophila mushroom body in juvenile and mature adult flies expressing a mushroom body-specific RNAi knockdown of Bap60. The results of this analysis suggested a role for Bap60 in the regulation of neurodevelopmental genes during a critical time window of juvenile adult brain development. Overall design: RNA from mushroom body nuclei was sequenced from Drosophila melanogaster expressing a mushroom body-specific RNAi knockdown of Bap60 or mCherry (control) in both juvenile (2 and 3 replicates, respectively) and mature (5 replicates each) adult flies.

Description
Single cell RNA Seq and bioinformatic analysis are used to study what processes are important for the molecular reprogramming of GMPs after 5-FU treatment. Samples were collected at different time points (0, 8, 10, 12 and 14 days post treatment) Overall design: Single cell RNA sequencing of GMP cells upon 5-FU treatment

Description
Synapse development and neuronal activity represent fundamental processes for the establishment of cognitive function. Structural organization as well as signalling pathways from receptor stimulation to gene expression regulation are mediated by synaptic activity and misregulated in neurodevelopmental disorders such as autism spectrum disorder (ASD) and intellectual disability (ID). Deleterious mutations in the PTCHD1 (Patched domain containing 1) gene have been described in male patients with X-linked ID and/or ASD. The structure of PTCHD1 protein is similar to the Patched (PTCH1) receptor; however, the cellular mechanisms and pathways associated with PTCHD1 in the developing brain are poorly determined. Here we show that PTCHD1 displays a C-terminal PDZ-binding motif that binds to the postsynaptic proteins PSD95 and SAP102. We also report that PTCHD1 is unable to rescue the canonical sonic hedgehog (SHH) pathway in cells depleted of PTCH1, suggesting that both proteins are involved in distinct cellular signalling pathways. We find that Ptchd1 deficiency in male mice (Ptchd1-/y) induces global changes in synaptic gene expression, affects the expression of the immediate-early expression genes Egr1 and Npas4 and finally impairs excitatory synaptic structure and neuronal excitatory activity in the hippocampus, leading to cognitive dysfunction, motor disabilities and hyperactivity. Thus our results support that PTCHD1 deficiency induces a neurodevelopmental disorder causing excitatory synaptic dysfunction. Overall design: 6 samples RNA-seq. 3 kos, 3wts.
