PolyA mRNA was extracted from anti HuR siRNA treated and mock transfected HeLa cells to identify changes in mRNA expression and splicing. 2x100 paired end sequencing was performed according to the protocol on the Illumina HiSeq. PARCLIP was performed as in Hafner et. Al 2010 but with an antibody against endogenous HuR (3A2, Santa Cruz, sc-5261) in unstressed HeLa cells. We used, independently, 4-thiouridine (4SU) and 6-thioguanosine (6SG) to assess a possible nucleotide bias. As our proteomics measurements required labeling of cells in a special medium we also performed PAR-CLIP on cells grown in SILAC medium. Altogether we performed three PAR-CLIP experiments: 4SU labeling in standard DMEM medium, 4SU labeling in SILAC medium (as a replicate) and 6SG labeling in SILAC medium. Small RNA was extracted from anti HuR siRNA treated and mock transfected HeLa cells to identify changes in mRNA expression. Sequencing was performed on Illumina GAII using the standard sRNA 36cycle protocol.
