MALAT1 and liver cancer: MALAT1 has more than 410 putative protein-binding partners in HeLa cells based on capture hybridization analysis of RNA targets (CHART) and over 120 putative binding partners in HepG2 liver cancer cells based on quantitative proteomics approaches and in PC3 prostate cancer cells based on hybridization purification of RNA-protein complexes followed by mass spectrometry (HyPR-MS) [38,39,40].
