We observed an increase in MALAT1 expression in gastric cancer tissues compared to normal tissues as well as a moderate positive correlation between CD163 (an indicator of TAM infiltration in tumors) and HIF‐1α gene expression (but not δ‐catenin) in gastric cancer tissues by analyzing TCGA data (Figure S10A–C, Supporting Information). Here, MALAT1 is linked to gastric cancer.
