Genome-wide study of the role of the histone demethylase dLsd1 in oogenesis

Project description:The histone demethylase LSD1 is a key chromatin regulator that plays a crucial role in development. It has been shown to act both as a co-repressor and a co-activator of genes expression and to affect the expression of many genes important for development. In Drosophila, dLsd1 is essential for oogenesis; however, our current knowledge of dLsd1 function is insufficient to explain its precise role in the ovary. To better define the role of dLsd1 in oogenesis, we performed genome-wide analysis of dLsd1 binding in the ovary by Chromatin Immunoprecipitation followed by sequencing (ChIP-Seq).

Transposable elements silencing by the histone demethylase dLSD1 is required to achieve normal wing size

Project description:Determination of tissue size depends on the proper response of cells to a wide array of external and internal signals. Chromatin acts as a platform/substrate of signal integration and storage. Signal transduction pathways converge upon chromatin modifying enzymes and transcription factors to reprogram gene expression. However, little is known about the role of chromatin modifying factors in determining tissue size. Here, we show that loss of function of the histone demethylase dLSD1 results in a significant reduction of Drosophila wing size due to a decreased cell number. We show that dLSD1 depletion affects proliferation and induces DNA damage in larval wing imaginal discs. Through transcriptomics analysis, we find that dLSD1 controls the expression of multiple gene networks in wing imaginal discs. We then show that normal dLsd1 function contributes to repressing Transposable Element (TE) transcription and mobility. Additionally, our results suggest that increased TE mobility due to dLsd1 depletion contributes directly to altered organ size.
