Densitometric analysis showed a statistically significant (p < 0.05) decrease in the levels of TfR1 (reaching a level of 70 ± 11% of non-HF control) and a statistically significant (p < 0.05) increase in the total levels of the iron influx transporter +/-IRE-DMT1 (118 ± 10% of non-HF control), mainly in bands corresponding to molecular weights of ~70 kDa and ~50 kDa. The gene discussed is TFRC; the disease is hydrops fetalis.
