Loss of the starvation-induced gene Rack1 leads to glycogen deficiency and impaired autophagic responses in Drosophila.

Autophagy 20120507 7

Autophagy delivers cytoplasmic material for lysosomal degradation in eukaryotic cells. Starvation induces high levels of autophagy to promote survival in the lack of nutrients. We compared genome-wide transcriptional profiles of fed and starved control, autophagy-deficient Atg7 and Atg1 null mutant Drosophila larvae to search for novel regulators of autophagy. Genes involved in catabolic processes including autophagy were transcriptionally upregulated in all cases. We also detected repression of ...[more]

Single cell RNA on hemocytes from wandering larvae of Drosophila melanogaster not infested and infested by Leptopilina boulardi

Project description:We aimed at characterizing the diverse hemocyte populations present in the hemolymph of the Drosophila larvae. The hemocytes were collected from wandering larvae infested by wasp (WI) or not infested (NI). The hemocytes were then sequenced using 10x genomics technology.

Transcriptional profiling by array of human cardiac progenitors and cardiomyocytes generated from embryonic bodies, directed differentiation of hESCs with PDGFa or co-culturing hESCs with END2 cell line.

Project description:Human cardiomyocytes can be generated from human embryonic stem cells (hESCs) in vitro by a variety of methods, including co-culture with visceral endoderm-like cell lines and growth factor directed differentiation as monolayers or three-dimensional embryonic bodies. To enable the identification, purification and characterisation of human embryonic stem cell derived cardiomyocytes (CMs) and cardiac progenitor cells (CPCs), we introduced sequences encoding GFP into the NKX2-5 locus by homologous recombination. We found that NKX2-5GFP hESCs facilitate quantification of cardiac differentiation, purification of hESC-derived committed cardiac progenitor cells and cardiomyocytes and the standardization of differentiation protocols.

Transcription profiling by array of Drosophila stage 14 oocytes

Project description:Mature stage 14 oocytes prior to egg activation were isolated from wild type Oregon Red fly cultures by a combined blender/ sieving method which allows specific and efficient enrichment of stage 14 oocytes. Total RNA was extracted from 4 replicate collections and submitted to Affymetrix microarray hybridisation.

Nkya et al 2014 - Insecticide resistance mechanisms associated with different environments in the malaria vector Anopheles gambiae. A case study in Tanzania

Project description:Nine Anopheles gambiae populations were sampled in three areas of Tanzania showing contrasting agriculture activity, urbanization and usage of insecticides for vector control. Insecticide resistance levels were measured in larvae and adults through bioassays with deltamethrin, DDT and bendiocarb. A microarray approach was used for identifying transcription level variations associated to different environments and insecticide resistance. the Ifakara strain originating from central Tanzania and susceptible to all insecticides was used as a reference strain.

Sequencing of the transcriptome from embryonic and larval hemocytes in gcm knock down background

Project description:Hemocytes were sorted from stage 16 embryos and wandering 3rd instar larvae in which gcm was knocked down using gcmRNAi and the driver srp(hemo)Gal4. The experiments were done in triplicate. The wild type controls at stage 16 embryo and wandering larvae are available under this assession number: E-MTAB-8702.

Bulk RNAseq on hemocytes from stage 16 embryos and wandering 3rd instar larvae of Drosophila melanogaster

Project description:The aim of this experiment is to compare the transcriptome of Drosophila hemocytes at two developmental stages: in stage 16 embryo, mostly free from any immune challenge and in larvae, which grow in bacteria rich environment. Transgenes inducing the expression of RFP in the hemocytes were used to sort the hemocytes from the two stages before carrying out the sequencing.

Transcriptional profiling by array of INSULIN-expressing cells derived from INS-GFP human embryonic stem cells under different differentiation and culture conditions

Project description:Differentiation of INSGFP/w hESCs using published protocols demonstrated that all GFP+ cells co-expressed insulin, confirming the fidelity of the reporter gene. INS-GFP+ cells also co-expressed glucagon and somatostatin, confirming prior studies regarding the polyhormonal nature of early hESC derived insulin-expressing cells. INSGFP/w hESCs were employed to develop a 96 well format spin Embryoid Body (EB) differentiation protocol that utilized the recombinant protein based fully defined medium, APEL. Like INS-GFP+ cells generated with other methods, those derived using the spin EB protocol expressed a collection of pancreatic related transcription factors including ISL1, PAX6 and NKX2.2. However, in contrast to previous methods, the spin EB protocol yielded INS-GFP+ cells that also co-expressed the beta-cell transcription factor, NKX6.1 and comprised a substantial proportion of monohormonal insulin+ cells.

Transcription profiling of Drosophila developmental time series

Project description:Michelle N. Arbeitman, Eileen E. M. Furlong, Farhad Imam, Eric Johnson, Brian H. Null, Bruce S. Baker, Mark A. Krasnow, Matthew P. Scott, Ronald W. Davis and Kevin P. White. Gene Expression During the Life Cycle of Drosophila melanogaster, Science, 297: 2270-2275, 2002. This work can be accessed from http://www.sciencemag.org/cgi/content/full/297/5590/2270. The abstract of this paper: Molecular genetic studies of Drosophila melanogaster have led to profound advances in understanding the regulation of development. Here we report gene expression patterns for nearly one-third of all Drosophila genes during a complete time course of development. Mutations that eliminate eye or germline tissue were used to further analyze tissue-specific gene expression programs. These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.
