SLC7A11 and neoplasm: Figure 6D shows that samples with high SLC7A11 expression have higher stromal scores, immune scores, and ESTIMATE scores, suggesting the more complex immune microenvironment in samples with high SLC7A11 expression. The SLC7A11 level was positively related to the stromal score, the immune score, and the ESTIMATE score and negatively related to tumor purity (Figure 6E).
