Figure 1. Analysis of UBR1 expression profile and GSEA in human cancers. (A) A comprehensive pan-cancer analysis was performed to evaluate UBR1 expression across various cancer and normal tissues using combined data from the TCGA and GTEX databases. Statistical significance is indicated as follows: ****p < 0.0001, ***p < 0.001, **p < 0.01, *p < 0.05. (B) To further understand the functional implications of UBR1 expression, a pan-cancer GSEA was conducted. This analysis identified significant enrichment of UBR1 in various signaling pathways across different cancer types.
