(Submitter supplied) Circadian neurons within animal brains orchestrate myriad physiological processes and behaviors, but the contribution of these neurons to the regulation of sleep is not well understood. To address this deficiency, we leveraged single-cell RNA sequencing to generate a new and now comprehensive census of transcriptomic cell types of Drosophila clock neurons. We focused principally on the enigmatic DN3s, which constitute most fly brain clock neurons and were previously almost completely uncharacterized. more...

(Submitter supplied) The molecular programs that drive proliferation and differentiation of intestinal stem cells (ISCs) are essential for organismal fitness. Notch signalling regulates the binary fate decision of ISCs, favouring enterocyte commitment when Notch activity is high and enteroendocrine cell (EE) fate when activity is low. However, the gene regulatory mechanisms that underlie this process on an organ scale remain poorly understood. more...

(Submitter supplied) Drosophila nephrocytes are specialised cells that share critical functional, morphological, and molecular features with podocytes of the mammalian kidney, including the slit diaphragm, which is a functional filtration barrier. Accordingly, nephrocytes are considered highly suitable invertebrate models for glomerular disease in humans. In this study, we established a method to individually isolate the garland and pericardial nephrocytes from Drosophila of different developmental stages. more...

(Submitter supplied) Epithelial organs maintain their integrity and prevent tumour initiation by actively removing defective cells, such as those that have lost apicobasal polarity. Here, we identify how transcription factors of two key signalling pathways – Jun-N-terminal kinase (JNK) and Hippo – regulate epithelial integrity by controlling transcription of an overlapping set of target genes. Targeted DamID experiments reveal that in proliferating cells of the Drosophila melanogaster eye, the AP-1 transcription factor Jun, and the Hippo pathway transcription regulators Yorkie and Scalloped bind to a common suite of target genes that regulate organ growth. more...

(Submitter supplied) CREB-Regulated Transcription Co-activator (CRTC) regulates metabolism in liver where activation by calcineurin regulates gluconeogenic genes. CaN also has roles in pathological cardiac hypertrophy, however cardiac roles for CRTC have not been identified. In Drosophila, CRTC null mutants exhibit severe cardiac restriction, myofibrillar disorganization, cardiac fibrosis, and tachycardia. Cardiac-specific knockdown (KD) of CRTC mimicked the heart defects of CRTC mutants and cardiac-overexpression (OE) of CRTC or calcineurin caused hypertrophy that was reduced in CRTC mutants, suggesting CRTC mediates calcineurin’s effects. more...

(Submitter supplied) Alternative Cleavage and Polyadenylation (APA) often results in production of mRNA isoforms with either longer or shorter 3’UTRs from the same genetic locus, potentially impacting mRNA translation, localization and stability. Developmentally regulated APA can thus make major contributions to cell-type-specific gene expression programs as cells differentiate. During Drosophila spermatogenesis, approximately 500 genes undergo APA when proliferating spermatogonia differentiate into spermatocytes, producing transcripts with shortened 3’ UTRs, leading to profound stage-specific changes in the proteins expressed. more...

(Submitter supplied) RNA interference (RNAi) is a gene-silencing mechanism triggered by the cytosolic entry of double-stranded RNAs (dsRNAs). Many animal cells internalize extracellular dsRNAs via endocytosis for RNAi induction. However, it is not clear how the endocytosed dsRNAs are translocated into the cytosol across the endo/lysosomal membrane. Herein, we show that in Drosophila S2 cells, endocytosed dsRNAs induce lysosomal membrane permeabilization (LMP) that allows cytosolic dsRNA translocation. more...

(Submitter supplied) Counterintuitively, increased tumour predisposition is associated with ribosomal protein (RP) loss. Here, we provide the first evidence that RP depletion can directly drive tissue overgrowth. Haematopoietic compartment-specific knockdown (KD) of RpS19a in the Drosophila lymph gland not only results in haematopoietic stem and progenitor cell (HSPC) loss but also drives excess proliferation and tissue overgrowth. more...

(Submitter supplied) Genome organization can regulate gene expression and promote cell fate transitions. The differentiation of germline stem cells (GSCs) to oocytes in Drosophila involves changes in genome organization mediated by heterochromatin and the nuclear pore complex (NPC). Heterochromatin represses germ-cell genes during differentiation and NPCs anchor these silenced genes to the nuclear periphery, maintaining silencing to allow for oocyte development. more...

(Submitter supplied) To determine the extent of alternative 3' end cleavage during Drosophila spermatogenesis, we performed 3' end sequencing of Drosophila testes from flies at different time points post heat shock (pHS) that were mutant for bam and also had a heat shock inducible transgene expressing Bam. We then performed Polysome profiling of testes at 24, 48 and 72 hours PHS and created 3' end sequencing libraries from the free, 40S, 60s, 80S, 2-3 ribosomes, and 4+ ribosomes fractions for each dataset

(Submitter supplied) Background: A prominent hallmark of aging is inflammaging—the increased expression of innate immune genes without identifiable infection. Model organisms with shorter lifespans, such as the fruit fly, provide an essential platform for probing the mechanisms of inflammaging. Multiple groups have reported that, like mammalian models, old flies have significantly higher levels of expression of anti-microbial peptide genes. more...
