Effects of mutation in a soluble guanylyl cyclase gene

ABSTRACT: Genomic and behavioral investigations were performed to determine the effects of a mutation in a Drosophila soluble guanylyl cyclase gene. A mutant DGCalpha1[3] third chromosome was crossed into a natural rover (for[R]) or natural sitter (for[s]) genetic background. (See Osborne et al. 1997; PMID: 9242616.) First instar larvae were collected and grown on 60mm Petri plates containing 10 mL of food until mid-third instar. (Approximate density was 3 animals per mL food). Larvae were collected and washed quickly with distilled water and were flash frozen in liquid nitrogen. Co-reared larvae were tested for behavioural effects. Four independent collections were made for each of the two conditions (Rover_DGCalpha1[3] or sitter_DGCalpha1[3]).

Drosophila soluble guanylyl cyclase mutants exhibit increased foraging locomotion: behavioral and genomic investigations.

Behavior genetics 20050501 3

Genetic variation in the gene foraging (for) is associated with a natural behavioral dimorphism in the fruit fly, Drosophila melanogaster. Some larvae, called 'rovers', have increased foraging locomotion compared to others, called 'sitters', and this difference is directly related to for-encoded cGMP-dependent protein kinase (PKG) activity. Here we report that larvae with mutations in the gene dgcalpha1, which encodes a soluble guanylyl cyclase (sGC) subunit, have increases in both PKG activity ...[more]

Thermoprotection in the Drosophila hsf4 mutant

Project description:In Drosophila larvae, acquired synaptic thermotolerance following heat shock has previously been shown to correlate with the induction of heat shock proteins (Hsps) including HSP70. We tested the hypothesis that synaptic thermotolerance would be significantly diminished in a temperature-sensitive strain (hsf4) which has been reported not to be able to produce inducible Hsps in response to heat shock. Contrary to our hypothesis, considerable thermoprotection was still observed at hsf4 larval synapses following heat shock. To investigate the cause of this thermoprotection, we conducted DNA microarray experiments to identify heat-induced transcript changes in these organisms. Transcripts of the hsp83, dnaJ-1(hsp40) and gstE1 genes were significantly up-regulated in hsf4 larvae after heat shock. In addition, increases in the levels of Hsp83 and DnaJ-1 proteins but not in the inducible form of Hsp70 were detected by Western blotting. The mode of heat shock administration differentially affected the relative transcript and translational changes for these chaperones. These results indicate that the compensatory up-regulation of constitutively expressed Hsps, in the absence of the synthesis of inducible Hsps including HSP70, could still provide substantial thermoprotection to both synapses and the whole organism. Two strains were used in this study; the mutant cn bw hsf4 strain, and the dp cn bw cl control strain from which the mutant was derived. For each strain, co-reared larvae were separated into a control group and a treatment group at random. RNA from the heat-shocked larvae and from the respective controls were directly compared on cDNA microarrays (GPL311). Two independent biological samples from each genotype were collected. In addition, an inter-strain comparison was made using the RNA from the untreated controls from each genotype. This was also performed in duplicate.

Cold hardening gene expression

Project description:Cold hardening treatment, a brief exposure to low temperatures (e.g. 0°C for 2 h), can protect certain insects against subsequent exposure to temperatures sufficiently low to cause damage or lethality. Microarray analysis to examine the changes in transcript abundance associated with cold hardening has been undertaken in Drosophila melanogaster in order to gain insight into this phenomenon. Transcripts associated with 36 genes were identified, a subset of which appeared to be also differentially expressed after heat shock treatment. Quantitative RT-PCR was used to independently determine transcript abundance of a subset of these sequences. Taken together, these assays suggest that stress proteins, including Hsp23, Hsp26, Hsp83 and Frost as well as membrane-associated proteins may contribute to the cold hardening response. Co-reared flies were separated into a control group and a treatment group at random. RNA was isolated from the cold-shocked flies and the respective controls and was used for direct comparisons on cDNA microarrays. Treatments were not varied as they had been optimized in previous studies. A pilot experiment was performed using the Drosophila 7k2 array (GPL311) and subsequently three pairs of independent biological samples were evaluated with the Drosophila 12k1 array (GPL1467).

Project description:Comparison of transcript abundance between control (untreated) and methotrexate treated S3 Drosophila cells and ovaries disected from female flies. S3 cells were exposed to 0 or 5.2 X 10^-8 M MTX for 4 days then harvested. Flies were exposed to 0 or 5 ppm MTX for 5 days then ovaries were dissected. RNA was extracted from S3 cells and ovaries. 4 S3 microarrays with one dye-swap and 2 ovary microarrays swapping dyes were hybridized to spotted cDNA microarrays.

Drosophila gene expression in response to the botanical insecticide Piper nigrum

Project description:This experiment was used to determine the effect of a botanical insecticide upon gene expression profiles in Drosophila melanogaster. Adult female Drosophila (oregon-R strain) were treated with an ethylacetate extract of Piper nigrum (Piperaceae) seeds formulated in 99% ethanol. Treatment was topical, using a Potter's tower to administer a total of 2 mL of a 0.9mg/mL concentration. Control treatment was identical except flies were treated with 99% ethanol as a solvent control. Gene expression was studied four hours post-treatment. The design is a direct comparison between total RNA of treated and untreated insects. Sample size is two and two reverse label hybridizations were done. Each sample is a pool of 240 insects which received the same treatment simultaneously.

Evalutation of the effect of ethanol upon gene expression in adult Drosophila melanogaster

Project description:This experiment was intended to determine if topical exposure to ethanol led to significant changes in gene expression in adult Drosophila melanogaster. It was determined that topical exposure to ethanol did not lead to a strong differential expression of genes in Drosophila after 4 hours. The effect of topical treatment with 99% ethanol was compared to the effect of a water treatment which was used as a control and the differential expression between these two treatments was assessed four hours after treatment. Two biological replicates of each treatment were compared for a total of two microarray hybridizations
