2624102-0	1989	Transferrin receptor expression in normal, iron-deficient and iron-overloaded rats.	Iron	43-47	transferrin receptor	Rattus norvegicus	0-20	
2624102-0	1989	Transferrin receptor expression in normal, iron-deficient and iron-overloaded rats.	Iron	62-66	transferrin receptor	Rattus norvegicus	0-20	
2624102-5	1989	Although the tissue distribution pattern of TfR-positive cells was similar in normal, iron-deficient and iron-overloaded rats, the staining intensity and number of TfR-positive cells were obviously higher in iron-deficient, and lower in iron-overloaded rats.	Iron	86-90	transferrin receptor	Rattus norvegicus	44-47
