TACSTD2 and neoplasm: We also found that the GSE1 and TACSTD2 expression levels had partial correlations of 0.18 (p = 1.72 × 10−4) and 0.15 (p = 2.13 × 10−3), respectively, with tumor-infiltrating or associated macrophages, and this is consistent with contemporary knowledge that tumor-infiltrating, or associated macrophages, are highly enriched in aggressive cancer subtypes, orchestrate stromal oncogenic signaling, and predict worse prognosis [19,20] (Figure 4G).
