FABP5 and neoplasm: To explore the potential application by modulating FABP5 activity, we used SBFI‐26, a small molecular chemical inhibitor for FABP5.[26] SBFI‐26 significantly repressed 786‐O proliferation in a dose‐dependent manner in vitro (Figure S6R, Supporting Information) and repressed tumor growth in vivo both in the subcutaneous and orthotopic xenograft models (Figure 3K–N).
