In lung adenocarcinoma cell lines, ribosomal and housekeeping genes reduce their relative expression diversity during drug treatment with the multi‐tyrosine kinase inhibitor Vandetanib (US trade name Caprelsa).45 Interestingly, their result indicates that genes that are directly targeted by the drug of interest, in this case the EGFR and RET genes, remain constant. The gene discussed is RET; the disease is lung adenocarcinoma.
