Moreover, the baseline LIX1 expression (mRNA and protein) was higher in GIST-T1/670 cells than in GIST-T1 cells (Figure 1E–G), and its expression further increased when we cultured GIST-T1/670 cells in the presence of sunitinib for 48 h (Figure 1H). The gene discussed is LIX1; the disease is gastrointestinal stromal tumor.
