NTSR1 and neoplasm: The results suggest that NTSR1 (Figures 14(c)–14(e)) and MAP3K19 (Figures 14(f)–14(h)) were closely related to stromal cell level, tumor purity, and immune cell infiltration level in the lung tumor microenvironment and may affected the prognosis of LUAD by changing the tumor immune microenvironment.
