Micropublication relevant to TRiP fly stocks

April 9, 2019

Users of TRiP RNAi and sgRNA fly stocks take note: the Weake lab at Purdue University brought to our attention that some TRiP fly stocks carry a mutant allele of seveneless. Jonathan Zirin worked with Spencer Escobedo and Vikki Weake, as well as with folks at the Bloomington Drosophila Stock Center, to quickly identify the source, sequence the mutant allele, and pubilsh a micropublication so we can get the details to the community. Bottom line, as stated in the micropublication, "The presence of the sev[21]  mutation will not generally affect the use of these stocks, as the X...

Navigating our online tools -- orthologs, literature mining, qPCR primers, and so much more!

February 14, 2019

We have been taking a critical look at how we organize our online tools on the Online Tools Overview page. And more generally, we have been thinking about new ways to spread the word about the many resources in our suite of online tools. One way that we at the DRSC like to think about these tools is how they fit into the start-to-finish order of events in a screen or other experimental project. Various tools help define lists of genes to be studied, help identify reagents for the study,...

Cell-based RNAi screening helps reveal host-microbe interactions--two new screen reports

November 19, 2018

Laboratories at the Skirball Institute at New York University and the Boyce Thompson Institute at Cornell University reported results of two different cell-based Drosophila RNAi screens in papers published this week. The screens have in common that they looked at interactions between the host insect cells and a microbe -- the endosymbiont Wolbachia in one study and baculovirus in the other. For more, check out the newly published studies. For both these screens, the DRSC provided libraries for screens that were then performed at the host institution.

Community Building and Online Resources at the DRSC/TRiP

August 14, 2018

At the DRSC/TRiP-Functional Genomics Resources, we are interested to let the community know about new resources we have built. We are also interested more broadly to help connect community members to additional resources that could help their research studies, foster collaborations, and build community.

One way in which we reach out to the community is by attending national and local fly group meetings. In 2018, this included or will include attendance at the ADRC fly meeting in Philly (spring 2018), and past or upcoming presentations at Flies on the Beach (FL),...

Missed us at ADRC 2018? View our workshop slides!

April 19, 2018
Thank you to all those who attended our workshop at last week's Annual Drosophila Research Conference in Philadelphia, PA, USA. It was great to talk fly stocks, cell screens, and bioinformatics with the community. We are here to help and look forward to continued feedback on the resources we are building to empower your research. PDFs of our workshop presentations are attached to this news item. The slides will help you learn more about our in vivo resources for CRISPR, new pooled cell-based CRISPR screen technology, and bioinformatics resources at our facility.  Feel free to contact...

Pooled-format CRISPR screens in Drosophila cells

March 22, 2018

The DRSC/TRiP-FGR is pleased to support collaborations on pooled CRISPR screens using the method recently, reported in eLife by Viswanatha et al. (PDF download file below).

From the abstract: "... Here, we developed a site-specific integration strategy for library delivery and performed a genome-wide CRISPR knockout screen in Drosophila S2R+ cells. Under basal growth conditions, 1235 genes were essential for cell fitness...

Congrats to Sung, Shears, and colleagues: "Cytokine signaling through Drosophila Mthl10 ties lifespan to environmental stress"

December 13, 2017

Eui Jae Sung, Stephen Shears, and colleagues have published a research report that includes a screen of dsRNAs from the DRSC reagent collection using S2 cells. We shipped dsRNA reagents to the lab for a screen at their home institution, in addition to providing consultation and data management support. The resulting study by Sung et al. was published on Dec. 11, 2017: Sung EJ, Ryuda M, Matsumoto H, Uryu O, Ochiai M, Cook ME, Yi NY, Wang H, Putney JW, Bird GS, Shears SB, Hayakawa Y. Cytokine signaling through Drosophila Mthl10 ties lifespan to environmental stress...
