Western blot analysis of ADA protein in retinoblastoma (Y79, WERI-Rb1, and Rb143), malignant atypical teratoid/rhabdoid tumors of the brain (AT/RT; BT37 and BT12), and diffuse midline gliomas, H3K27M mutant of the brain (DIPG007, SF7761, and JHHDIPG1) lines showed variable levels similar to those in uveal melanoma (Figure 6A). The gene discussed is ADA; the disease is uveal melanoma.
