Sequencing of the 3’ end of poly(A)+ RNA identifies cleavage and polyadenylation sites (pAs) and measures transcript expression. We previously developed a method, 3’ region extraction and deep sequencing (3’READS), to address mispriming issues that often plague 3’ end sequencing. Here we rep...
ORGANISM(S): Homo sapiens 
Most mammalian genes display alternative cleavage and polyadenylation (APA). Previous studies have indicated preferential expression of APA isoforms with short 3’UTRs in testes. Here we show widespread shortening of 3’UTR by APA during the first wave of spermatogenesis in mouse, with 3’UTRs be...
ORGANISM(S): Mus musculus 
Alternative cleavage and polyadenylation (APA) results in mRNA isoforms containing different 3’ untranslated regions (3’UTRs) and/or coding sequences. How core cleavage and polyadenylation (C/P) factors regulate APA is not well understood. Using siRNA knockdown coupled with deep sequencing, we found...
ORGANISM(S): Mus musculus 
Alternative cleavage and polyadenylation (APA) generates diverse mRNA isoforms. We developed 3' region extraction and deep sequencing (3'READS) to address mispriming issues that commonly plague poly(A) site (pA) identification, and we used the method to comprehensively map pAs in the mouse genome. T...
