ESR1 and neoplasm: In the cell scratch assay, the percentage of wound healing distance between the scratches was significantly lower in MCF-7 cells than in MDA-MB-231 cells after CPT intervention, Combined with the invasion experiment, it was shown that CPT can inhibit the migration of MCF-7, indicating that CPT may be involved in inhibiting the metastasis of ER-positive BRCA, And the latest research found that through different ways to affect and regulate the tumor microenvironment, the natural drug small molecule CPT has an anti-metastatic effect, and the mechanism of action needs further investigation.
