Comparison of Drosophila melanogaster Malpighian tubule v whole fly

Project description:This is an affymetrix array experiment comparing the transcriptome of the Malpighian tubule (or renal tubule) of 7-day adult Oregon R strain Drosophila melanogaster with matched whole fly samples. There are five tubule samples (each derived from approx 1000 tubules (!)), and 5 matched whole-fly samples. i.e. tubule 2 is dissected from the same vial as WholeFly2. As the tubule is probably the premier tissue for true physiology in Drosophila, the dataset can usefully be interrogated in conjunction with the detailed physiological understanding of the tissue: see http://fly.to/tubules

Natural variation affecting allele-specific expression in the Malpighian tubules of Drosophila melanogaster

Project description:We used RNA-seq to investigate natural variation in gene expression in the Malpighian tubules of three inbred Drosophila melanogaster strains and their F1 hybrids. One of the strains was from a population in the species’ ancestral range (Zambia), while the other two were from a more recently derived population (Sweden).

Population- and sex-biased gene expression in the excretion organs of Drosophila melanogaster

Project description:We used RNA-seq to investigate gene expression variation in Malpighian tubules, which have a function analogous to that of human kidneys. In order to characterize population differentiation, we sequenced the Malpighian tubule transcriptomes of flies derived from two populations, one from sub-Saharan Africa (Zimbabwe) and one from Europe (the Netherlands). Males and females were examined separately. Overall, we found a high amount of differential expression between sexes (2,308 genes) and populations (2,474 genes). Although most of the differentially expressed genes were consistent between sexes and populations, there were 615 genes showed sex-biased expression in only one population and 557 genes showed population-biased expression in only one sex. mRNA expression profiles of Drosophila melanogaster Malpighian tubules from adult males and females from a European and an African population (2 biological replicates per sex and population)

Transcriptional and functional motifs defining renal function revealed by single nuclear sequencing

Project description:Like humans, insects rely on precise regulation of their internal environments to survive. The insect renal system consists of Malpighian tubules and nephrocytes that share similarities to the mammalian kidney. Studies of the adult Drosophila Malpighian tubules and nephrocytes have led to many insights in our understanding of stem cell regeneration, protein reabsorption, excretion of waste products, and human kidney diseases. Here, we analyzed single-nucleus RNA sequencing (snRNA-seq) data sets to characterize the cell types of the adult male and female fly kidney.

Aedes aegypti Malpighian tubules are immunologically activated following systemic Toll activation

Project description:Canine heartworm is a widespread and potentially fatal mosquito-borne disease caused by infections with the parasitic nematode, Dirofilaria immitis. We have previously shown that systemic activation of the Toll immune pathway via silencing of the negative regulator Cactus in Aedes aegypti blocks parasite development in the Malpighian tubules, the mosquito renal organ. However, it was not established whether the Malpighian tubules were directly responding to Toll activation or were alternatively responding to upregulated proteins or other changes to the hemolymph driven by other tissues. Distinguishing these possibilities is crucial for developing more precise strategies to block D. immitis while potentially avoiding the fitness cost to the mosquito associated with Cactus silencing. This study defines the transcriptional response of Ae. aegypti Malpighian tubules after systemic Toll activation via intra-thoracic injection of dsCactus and found, like the response of whole mosquitoes, a significant increase in expression of Toll pathway target genes. Additionally, we identified a significant overlap between the transcriptional response of the Malpighian tubules and proteins upregulated in the hemolymph. Our data show that Malpighian tubules are capable of RNAi-mediated gene silencing and directly respond to dsCactus treatment by upregulating canonical Toll pathway targets. Though not definitive, the strong correspondence between the Malpighian tubule transcriptional and the hemolymph proteomic responses provides evidence that the tubules may contribute to mosquito humoral immunity.
