CETP and metabolic syndrome: We observed that at the 1‐month time point FE was associated with five genes involved in vitamin A metabolism including Cyp2b9, Cyp2c38, Rdh16, Cyp4a10, and Aldh1a1. Interestingly, in a recent study which also used the E3L.CETP mouse model, it was shown that hepatic expression levels of Cyp2b9, Cyp2c38, Rdh16, and Cyp4a10 in the mice that developed metabolic syndrome phenotypes with high‐fat diet were different from the ones that did not (Nasias et al., 2019).
