Figure 7. Correlation between UBR1 expression and immune cell infiltration. (A) The correlation between UBR1 expression and infiltrating immune cells was analyzed using the TIME algorithm. (B) Differences in immune, stromal, and ESTIMATE scores between high and low UBR1 expression groups were examined. (C) The EPIC algorithm was used to evaluate the expression of UBR1 and its relationship with immune-infiltrating cells. Significance levels are indicated as follows: *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001; ns, not significant.
