2. Figure 1
Subcellular localization of La in the liver. (a) XRF mapping of La (1) and Fe (2) in liver samples of La-loaded rats showing co-localization of both elements. (b) TEM image of liver tissue of rat with normal renal function not exposed to La showing smoothly contoured electron-dense particles within the lysosomes. (c) TEM image of liver tissue of La-loaded rat (dose: 0.3 mg/kg per day i.v., 4 weeks) showing electron-dense precipitates displaying a crystalline granular structure within the lysosomes. (d) EELS spectrum of electron-dense particles within lysosomes of liver tissue of La-loaded rat (dose: 0.3 mg/kg per day i.v., 4 weeks) evidencing the presence of La. (e) TEM image of liver tissue of La-loaded rats (dose: 0.3 mg/kg per day i.v., 4 weeks) with La being present in the bile canaliculus (artificially colored in brown for educational purposes). White arrows show mitochondria whereas black arrows indicate lysosomes.

3. Figure 2
La concentration in rat hepatocytes after incubation with serum-free cell culture medium containing 0, 2.5, 5.0, and 25.0 μg/l La as the La-Tf complex. Results show a time- and dose-dependent intracellular uptake of La by the hepatocytes. Data represent the mean±s.d. La concentration of 4 wells per condition and per time point.

9. Figure 8
Study setup of study no. 2. Animals received 1000 mg/kg per day La carbonate 6 days a week by oral gavage. At each time point at least six animals per group of CRF or NRF were killed. Biochemical blood analysis was performed before induction of CRF, at the start of the oral loading and at killing.

Study setup of study no. 3. Animals received either 1000 mg/kg per day La carbonate 6 days a week by gavage or 0.05 mg/kg per day 3 days a week by intravenous injection.
