MSX2 and neuroblastoma: We similarly analyzed available data for the following other cooperative TFs: PHOX2B ChIP-seq from the KELLY (45), BE2C (45) and CLB-GA (46) neuroblastoma cell lines; Phox2a ChIP-seq from mouse induced cortical motor neurons (47); MSX2 ChIP-seq from human trophoblast stem cells (48); eGFP-MSX2 ChIP-seq from the MCF7 cell line (49); and FLAG ChIP-seq performed on 3xFLAG-Barx1-EGFP infected immortalized E13.5 stomach mesenchymal cells (50).
