Next Generation Sequencing to determine the roles of RNA-binding proteins PCBP1 and PCBP2 on murine erythropoiesis

E14.5 fetal liver cells from CD-1 mice were enriched for hematopoietic progenitors. The purified hematopoietic progenitor cells were infected immediately with retroviruses encoding shRNAs that target Pcbp1, Pcbp2, as well as two sets of control shRNAs; Luciferase and scrambled sequence. The transduced cells were grown for 48 hours. These cells were collected (‘Day 0’ cells), or washed and resuspended in differentiation medium and incubated for an additional 2 days (‘Day 2’ cells). 1ug of total RNA isolated from ‘Day 0’ and ‘Day 2’ cells from each Pcbp1 or Pcbp2 depleted sample was used for cDNA library construction after polyA selection. A total of 9 samples were generated from each of the two time points: 3 controls; Pcbp1 knockdowns with three distinctly targeting shRNAs (sh1,3,4); Pcbp2 knockdown with three distinctly targeting shRNAs (sh1,3,4). Sequencing was carried out using a 150nt paired-end sequencing protocol. RNA-seqs to examine the impact of PCBP1 and PCBP2 on murine erythropoiesis
