HOXC6 and neoplasm: Importantly, instead of Multi-Omics Matrix Factorization 34, a more stable and effective algorithm CIBERSORT was performed to construct the cell infiltration classifier, which divided cells in bulk tumor tissue into 2 classifications (C1: HOXC6 high, HOXC8 high, BMP5 low; C2: HOXC6 low, HOXC8 low, BMP5 high).
