In addition to our previous work demonstrating that differentiation of human carcinoma NTERA-2 cells can be induced by an AHR-regulated Alu retrotransposon (Morales-Hernández et al., 2016), additional studies (see Section AhR in the Control of Gene Expression through Mobile Genetic Elements above) have identified a LINE-1 element that responds to AhR ligands during the differentiation of renal carcinoma cells (Ramos et al., 2011) and a LINE-1 that can retrotranspose upon AhR activation by food-borne mutagens (Okudaira et al., 2013). Here, AHR is linked to carcinoma.
