The effect of inhibition of receptor tyrosine kinase AXL on DNA damage response in ovarian cancer: https://www.nature.com/articles/s42003-023-05045-0 (22. juni 2023)
AXL inhibition with small molecule inhibitor R428 decreases cell proliferation and induces G2/M arrest.
The combination treatment of the AXL inhibitor R428 with ATR inhibitors exacerbated DNA damage compared to single agent treatments.
Our study was in agreement with previous findings showing a positive effect of AXL inhibition in combination with DDR inhibitors in multiple cancers. AXL inhibition was also reported to induce HR deficiency, leading to synergistic effects when combined with PARP1 inhibition in high AXL-expressing TNBC, NSCLC and HNSCC cell lines. Therefore, this relationship between AXL and DDR can be exploited to improve the therapeutic index, paving the way to the rational use of AXL and DDR inhibitors in combination therapy.
