A Transwell invasion experiment was conducted to study the effect of Prdx1 on the invasion of tumor cells, and the results showed that compared with the control group, there was a 30% decrease of tumor invasion capacity after Prdx1 inhibition and a 32% increase of tumor invasion capacity after Prdx1 was over-expressed (Fig. 2f, g). The gene discussed is PRDX1; the disease is neoplasm.
