To do so, we analyzed the growth of TC1 tumours in RAG−/− mice (lacking T and B cells) that had been supplemented with splenocytes obtained from either WT or RORα−/− animals (WT → RAG−/− and RORα−/− → RAG−/−) and compared them to the growth of TC1 tumours in WT or RAG−/− control animals (Fig. 6). Here, RORA is linked to neoplasm.
