Transcriptomics analysis of gene expression in normal and YTHDC1, SRSF1, SRSF3, SRSF7, SRSF9 or SRSF10 deficient human HeLa cells

ABSTRACT: RNA was isolated from and YTHDC1, SRSF1, SRSF3, SRSF7, SRSF9 and SRSF10 deficient human HeLa cells using the TRIzol (Invitrogen) reagent by following the company manual. For all samples the RNA integrity was checked using an Agilent Bioanalyzer 2100. All samples showed a RIN (RNA integrity number) of higher than 9. Approximately 2.5 µg of total RNA was then used for library preparation using a TruSeqâ?¢ RNA Sample Prep Kit v2 (Illumina, San Diego, CA, USA) according to the manufacturerâ??s protocol.The libraries were sequenced using HiSeq2000 (Illumina) in single-read or paired-read mode, creating reads with a length of 101 bp. Sequencing chemistry v2 (Illumina) was used and samples were multiplexed in two samples per lane.

The regulatory role of N(6)-methyladenosine (m(6)A) and its nuclear binding protein YTHDC1 in pre-mRNA splicing remains an enigma. Here we show that YTHDC1 promotes exon inclusion in targeted mRNAs through recruiting pre-mRNA splicing factor SRSF3 (SRp20) while blocking SRSF10 (SRp38) mRNA binding. Transcriptome assay with PAR-CLIP-seq analysis revealed that YTHDC1-regulated exon-inclusion patterns were similar to those of SRSF3 but opposite of SRSF10. In vitro pull-down assay illustrated a comp  ...[more]
