Project description:CEM.NKR.DC-SIGN cells were infected in vitro with DENV1 (strain WestPac74) for 18 hours, after which either total viable cells or viable cells expressing surface DENV1 NS1 were isolated by flow cytometric sorting. Sorted cells were processed for scRNAseq analysis using either a standard Oligo(dT) primer, or an Oligo(dT) primer supplemented with a DENV-specific RT primer

Project description:Small interspersed elements (SINEs) is transcribed by RNA polymerase III (Pol III) to produce RNAs of typically 100 to 500 nucleotides in length. Although the abundance of SINE RNAs can be analyzed by Northern blotting and primer extension, the nature (sequence, exact length, and genomic origin) of these RNAs cannot be revealed by these methods. Moreover, mRNA sequencing (mRNA-seq) is not able to distinguish bona fide SINE RNAs and SINE sequences present in longer transcripts. To elucidate the abundance, source loci, and sequence nature of SINE RNAs, we have established a deep sequencing method, designated as melRNA-seq (medium length RNA-seq), which can determine whole-length sequences of RNAs. The total RNA samples were treated with 5' Pyrophosphohydrolase (RppH), which allowed ligation of an RNA adaptor to the 5’ end of intact SINE RNAs. Another adaptor was ligated to the 3’ end, followed by reverse transcription, PCR amplification, size selection, and single-end deep sequencing. Analysis of two biological replicates of RNAs from mouse spermatogonia showed high reproducibility of the SINE expression data both at family level and locus level. Therefore, this new method can be used for the quantification and detailed sequence analysis of medium length non-coding RNAs, such as rRNA, snRNA, tRNAs, and SINE RNAs. The dynamic range is much wider than Northern blotting and primer extension.
