We thank the reviewers for encouraging us to perform such experiments. Samples were ordered based on time and treatment. Author information Article notes Copyright and License information Disclaimer. GalMyc] transgenic line is able to inhibit Gal4 activity upon heat shock. The GAL4-UAS system is a biochemical method used to study gene expression and function in organisms such as the fruit fly.

GAL4/UAS system – Wikipedia

Brand AH, Perrimon N. The Gal80 RNA-injected embryos begun to express Acin at 3 dpf, whose fluorescence peaked at 7 dpf, albeit less intensely than in control animals Fig.

Analysis of upstream elements in the HuC promoter leads to the establishment of transgenic zebrafish with fluorescent neurons. Relative TotM levels were measured 24 hr post injection. TotM relative levels were calculated 24 hr post injection.

Kaede expression in these animals was restricted to ocular muscles, compared to a more widespread expression in non-injected specimens.

EGFP] double transgenic eggs and followed the green fluorescence over time Fig.

Delaying Gal4-Driven Gene Expression in the Zebrafish with Morpholinos and Gal80

These results suggest that canonical STAT-dependent TotM induction in the fat body accounts for the global response seen in total fly extracts. For this purpose, we created a transgenic line to express a Myc-tagged Gal80 under the control of a heat-shock promoter Fig. Can the authors really say that their acttin supports this evolutionary argument?

Probir Chakravarty,Naren Srinivasan,Genome wide responses to extracellular actin,https: Journal of Experimental Medicine.

We crossed a Tg[UAS: The motivation behind it is that UAS: They also suggest that the gradual release of Gal4 inhibition likely due to the degradation of the Gal80 allows the expression of the UAS-driven genes at later stages yal4 development with an average onset at 4 dpf. Annual Review of Pathology: The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

The morphant approach can also be applied to transgenic lines expressing the Gal4-VP16 fusion protein. Thank you for submitting your article “Actin is an evolutionarily-conserved damage-associated molecular pattern that signals actln injury ga,4 Drosophila ” for consideration by eLife. In control embryos without heat-shock, we could not detect Gal80 RNA.

Also, temperature-sensitive mutant forms of Gal80 and Gal4 have been exploited along with ligand-based technologies to further enhance conditional control [7]. As we have shown, this driver line expresses the Gal4-VP16 in lateralis afferent ganglia, ocular and trunk nerves, but also has strong and variable background expression in muscle and the heart.

G- and F-actin induce a unique sterile inflammatory response upon injection into Drosophila. Figure 2—figure supplement 2. The following day, the resulting embryos were analyzed for gross anatomical defects and for catin expression of green-fluorescent Kaede Fig. By contrast, embryos submitted to the heat-shock displayed widespread expression of Gal Targeted gene expression by the Gal4-UAS system in zebrafish.

Remote control of intestinal stem cell activity by haemocytes in Drosophila. Gal4 morpholino temporarily inhibits Gal4 expression in Gal4-VP16 lines. Indeed, the levels of TotM acfin by actin are equivalent between germ-free and commensal-bearing flies. Kaede] Gal4-morphants did not express Kaede for at least 72 hours after fertilization Fig.

It consists of a cellular and a humoural arm, in addition to cell-intrinsic antiviral RNAi responses Buchon et al. Haemocytes are labelled with GFP. Relative expression levels of TotM 24 hr post injection are shown.
