NR5A2 and cancer: Both CCK‐8 experiments and clone formation experiments confirmed that the knockdown of NR5A2 had a significant inhibitory effect on the proliferative ability of cells, and in clone formation experiments, cisplatin had a stronger clone‐forming ability on cells than the sh‐NR5A2 group, which suggests that the effect of NR5A2 may be more effective than that of cisplatin in inhibiting the proliferation of cancer cells, and of course, this may or may not have been due to a single setting of cisplatin's concentration results.
