Cre-ERT mediated antiviral induction


ABSTRACT: In this work, we aimed at studying the impact of microRNAs on antiviral responses, using inducible deletion of one or two copies of Dicer1 (in Dicer-floxed x EsrCRE+ MEFs). Unexpectedly, we discovered that Cre-ERT activation by hydroxytamoxifen (OHT) alone, independent of Dicer1 deletion, had a strong impact on antiviral responses. These microarrays were performed on SV40 immortalized Dicer1 fl/fl EsrCRE+ MEFs, Dicer1 fl/wt EsrCRE+ MEFs, 96 h after initial OHT treatment, and SV40 immortalized Dicer1 wt/wt EsrCRE+ MEFs, Dicer1 wt/wt EsrCRE-neg MEFs (Wild Type MEFs), 48 h after initial OHT treatment. These analyses revealed the strong induction of several antiviral genes (Rsad2, Cxcl10...), following Cre-ERT activation. SV40 immortalized mouse embryonic fibroblasts from various genotypes were stimulated 24h with 500nM hydroxytamoxifen, and further expanded for 24 or 72h. Each sample was analyzed on Agilent-028005 SurePrint G3 Mouse GE 8x60K Microarray Each sample is in simplicate - no biological replicates; sample 1-4 were processed/analyzed on a different microarray slide to 5-8 (different day/operator)

Gene-recombinase technologies, such as Cre/loxP-mediated DNA recombination, are important tools in the study of gene function, but have potential side effects due to damaging activity on DNA. Here we show that DNA recombination by Cre instigates a robust antiviral response in mammalian cells, independent of legitimate loxP recombination. This is due to the recruitment of the cytosolic DNA sensor STING, concurrent with Cre-dependent DNA damage and the accumulation of cytoplasmic DNA. Importantly,  ...[more]
