PIP4K2A and nasopharyngeal carcinoma: Based on these findings, we extracted the top 10 upregulated genes expressed in each malignant cell subtype and observed significant positive correlations with the four LRGs core genes, except for B4GALNT1, KIF5A, and TSFM in NPC-like malignant cells and PIP4K2A in OPC-like malignant cells (Figure 6L).
