A Drosophila proto-oncogene homolog controls aggression via aminergic neurons

Project description:Modulation of action choices according to the environmental context is crucial for animal survival and reproductive success1. Aggression, despite its general importance as a social behavior2, can become detrimental if uncontrolled3,4. However, the genetic and neural basis for aggression control through active suppression remains largely unknown. Here we found nvy, a Drosophila homolog of vertebrate myeloid translocation gene (MTG)5 involved in transcriptional regulation6-8, suppresses aggression through a specific subset of neurons. Mutation of the nvy gene resulted in hyper-aggressiveness, which was rescued by neuronal expression of human MTGs as well as Drosophila nvy. The mutant exhibited persistent aggression under various contexts in which wild-type flies switch their behavioral patterns. Knockdown of nvy in octopaminergic/tyraminergic (OA/TA) neurons increased aggression, phenocopying the nvy deletion. Cell-type specific transcriptomics on OA/TA neurons derived from the nvy mutants revealed aggression-controlling genes that are likely downstream of nvy. Moreover, we found that the nvy-expressing OA/TA neuronal subpopulations specifically suppress aggression. Our results presents a powerful genetic model to unravel not only the neuronal systems that modulate aggression in a social context-dependent manner, but also the conserved molecular mechanism underlying the tumorigenesis caused by the MTG mutations.

The proto-oncogene DEK regulates neuronal excitability and tau accumulation in Alzheimer’s disease vulnerable neurons [RNA-seq_invivo]

Project description:Neurons from layer II of the entorhinal cortex (ECII) are the first to accumulate tau protein aggregates and degenerate during prodromal Alzheimer’s disease. We used a data-driven functional genomics approach to model ECII neurons in silico that led us to the prediction that the proto-oncogene DEK is a driver of tau pathology in these neurons. In order to understand the function of DEK in vulnerable neurons, we modulated its expression in ECII neurons in vitro and in vivo in the mouse. The present GEO entry corresponds to cell-type specific RNA-sequencing of ECII neurons in vivo 1 week after DEK silencing using AAV vectors.

The proto-oncogene DEK regulates neuronal excitability and tau accumulation in Alzheimer’s disease vulnerable neurons [chromatin]

Project description:Neurons from layer II of the entorhinal cortex (ECII) are the first to accumulate tau protein aggregates and degenerate during prodromal Alzheimer’s disease. We used a data-driven functional genomics approach to model ECII neurons in silico that led us to the prediction that the proto-oncogene DEK is a driver of tau pathology in these neurons. In order to understand the function of DEK in vulnerable neurons, we modulated its expression in ECII neurons in vitro and in vivo in the mouse. Since DEK is a chromatin modulator, we investigated the genomic location of a few histone marks in DEK silenced cells using the CUT&TAG approach, as well as Chromatin Accessibility using ATAC-seq

We used a data-driven functional genomics approach to model ECII neurons in silico that led us to the prediction that the proto-oncogene DEK is a driver of tau pathology in these neurons. In order to understand the function of DEK in vulnerable neurons, we modulated its expression in ECII neurons in vitro and in vivo in the mouse. The present GEO entry includes all of the data we collected from DEK-silenced and DEK-overexpressing ECneurons in vitro and in vivo.
