SIK2 and uveal melanoma: We showed in additional cellular models including human metastatic uveal melanoma cells (OMM2.5 and OMM1) and primary uveal melanoma cells (92.1 and Mel270) that adding back wild‐type SIK2 alleviated the hyperproliferative phenotype mediated by LKB1 loss (Fig EV4C and D and Appendix Fig S4).
