LINC-PINT and cancer: We then confirmed that LINC-PINT and PRC2 interact in human cells of different origins, including normal and cancer cell lines, by detecting specific enrichment of LINC-PINT in PRC2 immunoprecipitates (Fig. 6a and Additional file 1: Figure S6B–D), as well as the reciprocal RNA pulldown experiments (Fig. 6b).
