DsGFP as exogenous control on RNAi assays and its effects on gene expression in Apis mellifera

ABSTRACT: Double stranded RNAs are used to induce gene silencing in functional studies. In Apis mellifera green fluorescent protein (GFP) dsRNA (dsGFP) has been used as an exogenous control as its sequence has no homology in honeybee genome. However, some undesirable effects are observed after dsGFP treatment. A microarray approach comparing gene expression differences between untreated and dsGFP treated groups, containing honeybees workers in two different developmental stages, pre-pupae and light-brown eyed pupae, were used to test the reliability of dsGFP as a control for RNAi experiments. According to these microarrays results dsGFP can be used as a control in RNAi assays as long as the affected genes are taken into account in the analysis. Analysis used loop-design to compare dsGFP treated and noon-treated workers in pre-pupae and light-brown-eyed pupae stages.

Drosophila Gene Expression During Metamorphosis in Wild Type and Germline Minus Pupae

Project description:Drosophila melanogaster undergoes a complete metamorphosis, during which time the larval male and female forms transition into sexually dimorphic, reproductive adult forms. To understand this complex morphogenetic process at a molecular-genetic level, we performed whole genome microarray analyses. Genes were identified that were expressed during metamorphosis in both somatic and germline tissues of males and females. Additionally, genes were identified that display sex-specific differences in abundance in both of these tissues at discrete times during metamorphosis. Keywords: time course; wild type; genetic modification; Gene expression was examined at five time points during metamorphosis: 0, 24, 48, 71, and 96 hr After Puparium Formation (APF). Gene expression was examined separately in males and females for both wild type pupae and tudor (tud) progeny. tud progeny have genetically ablated germline tissues. All samples were labeled with Cy5 and compared against a common reference sample labeled with Cy3. The reference sample contained male and female wild type pupae from all stages of metamorphosis. All experiments were conducted in triplicate.

Proteomics profiling of the honeybee parasite Tropilaelpas mercedesae across post-embryonic development

Project description:All T. mercedesae samples were collected from capped brood cells using a soft paintbrush and soft tweezers. Reproductive mites (Rep) were collected from brood cells containing white-eyed pupae. Protonymphs (Pro) and one deutonymphs (Deu) were sampled from brood cells containing purple-eyed pupae. Adult T. mercedesae (Adu) were collected from cells close to emerge (about one day before adult bees emerge). For each group (protonymphs, deutonymphs, adults, and reproductive mites), collected mites from all 12 colonies were randomly allocated to one of three replicates (50 mg for each replicate). All samples were rinsed with PBS and air-dried to remove many contaminates that may have been attached to the cuticle, flash-frozen using liquid nitrogen, and stored at -80°C for further processing.

Transcription profiling of Drosophila wild type and mir-8 homozygous mutants at 72 hours after puparium formation

Project description:Expression profiling of Drosophila mir-8 homozygous mutant pupae at a single developmental stage (72 hours APF). Homozygous mutant and wild type pupae were collected at 72 hours APF (After Puparium Formation). Three independent collections were performed. Total RNA was extracted and amplified. Mutant and respective wildtype samples were hybridized together to custom cDNA arrays (DGC1 and 2 EST collections).

Impact of Nosema apis infection on worker honey bee midgut gene expression

Project description:Newly emerged adult workers (24 hours old) were infected with 50,000 Nosema apis spores in sucrose solution. Controls were fed sucrose. Workers were maintained in cages in an incubator and collected at 1 and 2 days post-infection. Midguts were dissected and whole genome expression in this tissue was compared across treatments and collection time points using microarrays.
