The drug sensitivity analysis was performed by the GSCA website to find the sealed interactions between ARHGAP39 and cancer chemotherapeutic drugs, and the results showed that cells with high expression of ARHGAP39 are resistant to 28 drugs, such as sunitinib, etoposide, clofarabine, and so on, and sensitive to 1 drug, namely austocystin D (Figure 9B). Here, ARHGAP39 is linked to cancer.
