Transcriptiome of mouse erythroid cells (part2) poly(A)-

ABSTRACT: We report genome-wide maps of transcription in mouse erythroid cells. We used an approach to survey poly(A)+ (mRNA) (Transcriptiome of mouse erythroid cells (part1) GSE26877) and non-polyadenylated RNA separately. This provides an alternative framework for comprehensive transcriptome profiling in mammalian cells. Examination of non-polyadenylated RNA in mouse erythroid cells (Ter119+).

A substantial amount of organismal complexity is thought to be encoded by enhancers which specify the location, timing, and levels of gene expression. In mammals there are more enhancers than promoters which are distributed both between and within genes. Here we show that activated, intragenic enhancers frequently act as alternative tissue-specific promoters producing a class of abundant, spliced, multiexonic poly(A)(+) RNAs (meRNAs) which reflect the host gene's structure. meRNAs make a substan  ...[more]
