We evaluated HuR’s role as a pre-mRNA splicing regulator by using RNA immunoprecipitation (IP) followed by RNA-seq of bound RNA (RIP-Seq) data (publicly available from the ENCODE project47) obtained from GM12878, a lymphoblastoid cell line, and K562, a myelogenous leukemia cell line. The gene discussed is ELAVL1; the disease is myeloid leukemia.
