Project description:To examine the repertoires of genes expressed in individual fru P1-expressing neurons, we performed single cell sequencing. The analysis was performed on male and female central nervous system tissues (48-hour pupal stage), from flies that expressed membrane-bound GFP in fru P1 neurons. We chose this developmental stage to gain further insight into how genes direct development of fru P1 neurons, as this is the stage where FruM has peak expression (in ~2,000 neurons).

Project description:Background: MicroRNAs (miRNAs) are expressed by a wide range of eukaryotic organisms, and function in diverse biological processes. Numerous miRNAs have been identified in Bombyx mori, but the temporal expression profiles of miRNAs corresponding to each stage transition over the entire life cycle of the silkworm remain to be established. To obtain a comprehensive overview of the correlation between miRNA expression and stage transitions, we performed a whole-life test and subsequent stage-by-stage examinations on nearly one hundred miRNAs in the silkworm. Results: Our results show that miRNAs display a wide variety of expression profiles over the whole life of the silkworm, including continuous expression from embryo to adult (bmo-miR-184), up-regulation over the entire life cycle (bmo-let-7 and miR-100), down-regulation over the entire life cycle (miR-124), expression associated with embryogenesis (miR-29 and miR-92), up-regulation from early 3rd instar to pupa (miR-275), and complementary pulses in expression between miR-34b and miR-275. Stage-by-stage examinations revealed further expression patterns, such as emergence at specific time-points during embryogenesis and up-regulation of miRNA groups in late embryos (miR-1 and bantam), expression associated with stage transition between instar and molt larval stages (miR-34b), expression associated with silk gland growth and spinning activity (miR-274), continuous high expression from the spinning larval to pupal and adult stages (miR-252 and miR-31a), a coordinate expression trough in day 3 pupae of both sexes (miR-10b and miR-281), up-regulation in pupal metamorphosis of both sexes (miR-29b), and down-regulation in pupal metamorphosis of both sexes (miR-275). Conclusions: We present the full-scale expression profiles of miRNAs throughout the life cycle of Bombyx mori. The whole-life expression profile was further investigated via stage-by-stage analysis. Our data provide an important resource for more detailed functional analysis of miRNAs in this animal.

Project description:Transcriptional regulation by Store-operated Calcium Entry (SOCE) is well studied in non-excitable cells. However, the role of SOCE has been poorly documented in neuronal cells with more complicated calcium dynamics. Previous reports demonstrated a requirement of neuronal SOCE for Drosophila flight. We identified the early pupal stage to be critical and used RNA-sequencing to identify SOCE mediated gene expression changes in the developing Drosophila pupal nervous system. We down-regulated dStim, the endoplasmic reticular calcium sensor and a principal component of SOCE in the nervous system for a 24h period during pupal development, and compared wild type and knockdown transcriptional profiles, immediately after knockdown as well as after a 36h recovery period. We found that dStim knockdown altered the expression of a number of genes. We also characterized one of the down-regulated genes, Ral for its role in flight. Thus, we identify neuronal SOCE as a mechanism that regulates expression of a number of genes during the development of the pupal nervous system. These genes can be further studied in the context of pupal nervous system development.
