Figure 6. Poly-A+ transcriptome composition and dynamics during 2–5AMD.
(A) Time evolution of the poly-A+ transcriptome obtained from spike-in RNA-seq. Induced transcripts (red) were upregulated by ≥ 5-fold at four hours of poly I:C treatment. (B) Illustration of read increase for a gene that is induced. (C) Levels of select basal and defense mRNAs measured by spike-in RNAs-seq. (D) Induction of innate immune mRNAs in response to poly I:C with and without 2–5AMD. (E) Experimental outline for measurement of innate immune mRNA decay. Innate immune mRNAs are allowed to accumulate followed by transcriptional inhibition with actinomycin D and decay profiling. (F) Kinetics parameters of defense mRNAs measured as in Fig. 4B. P-value compares T1/2 for defense vs basal mRNAs in Fig. 4C. See also Table S3.
