In addition, IHC staining suggested that the positive cells of Ki67, MMP9, and SLC7A5 in xenografts of the sh‐MRPL35 group were reduced, which were rescued in xenografts of the sh‐MRPL35 + SLC7A5 group (Figure 7D), indicating that MRPL35 might suppress NSCLC cell proliferation and invasion by regulating SLC7A5 in vivo. The gene discussed is MMP9; the disease is non-small cell lung carcinoma.
