It has previously been reported that dietary fat, in particular linolenic acid, has a strong impact on the secretion of ghrelin (Janssen et al., 2012; Lu et al., 2012; Gong et al., 2014), therefore we next examined whether the number of ghrelin cells in the corpus region may change upon feeding of a HF diet. The gene discussed is GHRL; the disease is hydrops fetalis.
