Next Generation Sequencing Facilitates Quantitative Analysis of Drosophila larval Wild Type and TFAM RNAi (r4-gal4>TFAM RNAi) Fat body Transcriptomes

Project description:Purpose: The goal of this RNA-Seq is to analyze the transcriptomes from wild type and TFAM RNAi fat body samples at 96 hr AEL (after egg laying) and to identify the differentially expressed genes. Methods: Drosophila larval fat bodies were isolated from wild type and TFAM RNAi (r4-gal4) animals at 96 hrs AEL (after egg laying) of development. mRAN profiles were generated by Next Generation Sequencing Facilities. Results: RNA Seq differential expression analysis identified a significant change in 1758 transcripts, with 1213 transcripts showing reduced expression levels and 545 transcripts with elevated expression levels.

mRNA-seq in Drosophila larval fat body

Project description:We performed mRNA-seq from hand-dissected fat body tissue from 68hr (after egg laying, AEL) and 92hr AEL Drosophila melanogaster larvae. Fat body was dissected from wild-type (OrR) males and testes were removed. We examined gene expression genome-wide with particular focus on genes in the underreplicated regions in the fat body.

ORC2 ChIP-seq in Drosophila larval fat body

Project description:We analyzed Origin Recognition Complex Subunit 2 (ORC2) ChIP-seq from hand-dissected fat body tissue from 68hr (after egg laying, AEL), 92hr AEL, and late-third wandering Drosophila melanogaster larvae. Fat body was dissected from wild-type (OrR) males and testes were removed. We examined ORC2 binding genome-wide with particular focus on the underreplicated regions in the fat body.

Expression profile analysis of Drosophila melanogaster embryonic and larval MANF mutants together with paternal rescue and overexpression conditions

Project description:To find out possible pathways and processes influenced by DmMANF we compared the changes in MANF null and overexpressing animals. We used two developmental stages of Drosophila, st 17 embryos and 29-50 hrs after egg laying (AEL) larvae. The timing were decided according to the lethality of MANF mutants with or without maternal contribution of MANF. Maternal and zygotic MANF mutants (MANFmzD96) were compared to paternal rescue and wild type embryos of the same age. Zygotic MANF mutants (MANFD96) with maternal contribution were compared to wild type and MANF ectopic overexpression larvae harvested well before the average lethality occured (75 hrs AEL). The changes in expression profiles were more drastic in MANFmzD96 embryos than in MANFD96 larvae. Gene ontology annotations were analyzed and clustered by DAVID. The major result was alterations in membranes, changes in membrane transporter expressions and disturbed intracellular membrane traffic. The results were verified by qPCR and transmission electron microscopy. Two developmental stages - 21-24 hrs and 29-50 hrs AEL of MANFD96 mutants without and with maternal contribution were compared to wild type (Wmix means crossed w1118 x w- ) and with paternal rescue or ectopic overexpression of MANF respectively by Drosophila Agilent microarray expression platform.
