It was found that upregulation of FABP4 suppressed GC cell metastasis (mice with FABP4-overexpressing tumours showed significantly lower number of metastatic colonies in the lungs than mice with tumours that did not overexpress) FABP4 (Figure 2A-B), while downregulation of FABP4 expression increased metastasis (Figure 2C-D). The gene discussed is FABP4; the disease is neoplasm.
