Hnrnp 1

Sources of primary antibodies: c-Myc from Abcam (Cambridge, MA, USA); GAPDH from Protein Tech (Chicago, IL, USA); hnRNP I and AUF1 from Santa Cruz Biotechnology (Dallas, TX, USA). Secondary antibodies conjugated with IRDye 800CW or IRDye 680 were purchased from LI-COR Biosciences (Lincoln, NE, USA).
PCR primers were purchased from IDT (Coralville, IA, USA). Linc-RoR and control siRNAs were purchased from ThermoFisher Scientific (Waltham, MA, USA). hnRNP I or AUF1 siRNA mixture was purchased from Santa Cruz Biotechnology. Colon cancer tissue cDNA arrays were purchased from OriGene (Rockville, MD, USA). Breast cancer tissue microarrays (TMAs) were purchased from US Biomax (Rockville, MD, USA).

Sources of primary antibodies were: p27 and Ki-67 from Cell Signaling (Danvers, MA, USA); hnRNP I from Santa Cruz Biotechnology (Dallas, TX, USA); GAPDH from ProteinTech (Chicago, IL, USA); and β-actin from Sigma-Aldrich (St. Louis, MO, USA). Antibody against phosphorylated hnRNP I were custom made from a synthetic peptide GTKRGSDELF with Ser-16 phosphorylated (PTBP1 amino acids 11–20) by Alpha Diagnostics (San Antonio, TX, USA) using the same procedure as previously described.^{46 (link)} Secondary antibodies conjugated with IRDye 800CW or IRDye 680 were purchased from LI-COR Biosciences (Lincoln, NE, USA).
