Mining the Kaplan‐Meier Plotter database revealed that up‐regulation of MCOLN1 (P = 4.6 × 10−2 and 4.4 × 10−2), RAB3A (P = 7.4 × 10−7 and 5.5 × 10−6), or LAMP1 (P = 3.2 × 10−3 and 2.3 × 10−2) was associated with poor overall or event‐free survival in gastric cancer patients (Figure S4D, Supporting Information). Here, MCOLN1 is linked to gastric cancer.
