In addition, the HF and HP diets, as those used in our experiment, usually imply a decrease in carbohydrate content; therefore, we also analysed the expression of a key glycolytic gene (Eno1) and of a relevant glucose transporter (Glut4) to be considered as potential early biomarkers of dietary imbalance in PBMC. Here, SLC2A4 is linked to hydrops fetalis.
