The proliferation ability of control and experimental cells was subsequently examined, and the results showed that the proliferation of breast cancer cells was significantly slowed down after G3BP1 was knocked down (Figure 2B), and this result was confirmed in a breast cancer xenograft model, where the tumor size and weight following G3BP1 knockdown were significantly reduced in nude mice (Figure 2C). The gene discussed is G3BP1; the disease is breast cancer.
