Figure 4. Enrichment analysis of NOX4-related genes across pan-cancers. (A) Identification of NOX4-binding proteins using the STRING tool. (B) Exploration of the top five NOX4-correlated genes across pan-cancers and their relationships with NOX4 expression analyzed through the GEPIA2 website. (C) Potential biological functions analysis of NOX4 by Metascape; presentation of enriched terms with a similarity >0.3 connected by edges.
