- Low density lipoproteins and high density lipoproteins were isolated from healthy donor plasma by a potassium bromide differential density gradient centrifugation separation technique (KBr) (Redgrave Technique, 1975). After extraction, the lipoproteins were adjusted to a cholesterol concentration of 1 mM. ⁇ of a solution of cisplatin (at 10 mg / ml, in saline) was then added for an expected final concentration of 1 mg / ml. In order to allow the combination of cisplatin with lipoproteins and to eliminate the unbound fraction of cisplatin, the samples were incubated for 3 hours at 37 ° C. and then subjected to two successive dialyses (compared with 1000 times the volume of phosphate buffered saline).
- KBr potassium bromide differential density gradient centrifugation separation technique
- cisplatin concentration was determined by graphite furnace absorption spectrometry (GF-AAS) ( Figure 1A).
- the concentration of cisplatin in LDL is 0.3 mg / mL of final solution, ie the solution obtained by adding lipoproteins in a solution of phosphate buffered saline (PBS) containing cisplatin.
- the cisplatin concentration in HDL is 0.5 mg / mL of said final solution.
- LDL containing vectorized cisplatin (LDL-C18) were incubated for 18 hours at 37 ° C with native HDL (HDL 0). Similarly, HDL containing vectorized cisplatin (HDL-C18) were therefore incubated for 18 hours at 37 ° C. with native LDL (LDL 0).
- lipoprotein fractions were extracted by a potassium bromide (KBr) differential density gradient ultracentrifugation separation technique.
- KBr potassium bromide
- the amount of cisplatin bound to the different fractions was then determined by graphite furnace absorption spectrometry (GF-AAS).
- Adenocarcinoma cells and macrophages are mostly found in colon tumors.
- SW480 colorectal cancer lines were treated for 48 hours with native LDL (LDL 0), native HDL (HDL 0), non-vectorized cisplatin, LDL-Cis or HDL-Cis (final concentration of cisplatin: 25 ⁇ l).
- LDL 0 native LDL
- HDL 0 native HDL
- non-vectorized cisplatin LDL-Cis
- HDL-Cis final concentration of cisplatin
- human macrophages were differentiated from monocytes into macrophages of alternating phenotype M2 (pro-tumoral). These macrophages were then stimulated for 2 hours with native LDL (LDL 0), native HDL (HDL 0), non-vectorized cisplatin, LDL-Cis or HDL-Cis (final cisplatin concentration: 25 ⁇ ).
- ROS reactive oxygen species
- DHE Dihydroethidium
- LDLox + Cis oxidized LDL lipoproteins loaded with cisplatin
- LDLox + Cis induce a macrophage activation greater than that induced by HDL-Cis.
- the oxidized LDLs were obtained by incubation of native LDL (cholesterol, 1 mM) for 24 hours at 37 ° C in the presence of copper sulphate (5 ⁇ l). After oxidation, the oxidized LDLs are dialyzed in PBS buffer.
- This test aims to verify that the vectorization of cisplastin makes it possible to reduce the general and renal toxicity in comparison with non-vectorized cisplatin.
- cisplatin administered at a dose of 20 mg / kg for 3 days to our murine model previously described, ie the ectopic (subcutaneous) allograft model of CT-26 colonic tumors in the BALB-C mouse, (validated protocol for cisplatin-induced nephrotoxicity).
- non-vectorized cisplatin induced, on the one hand, a weight loss of nearly 15% compared to the control sample (CTL).
- CTL control sample
- histological analyzes not shown
- non-vectorized cisplatin induces a strong nephrotoxicity which is characterized by de-epithelializations, the presence of hyaline bodies and phenomena of necrosis and apoptosis.
- no weight loss or signs of nephrotoxicity were observed for the cisplatin group vectorized by LDL (see Figure 5B).
- the vectorization of cisplatin reduces the toxicity associated with the use of the latter in comparison with non-vectorized cisplatin.
- cisplatin vectorized by LDL causes apoptosis of the cells within the tumor but not that of the renal cells (histological analysis not shown).
- the use of vectorized cisplatin thus makes it possible to overcome the side effects associated with the use of non-vectorized cisplatin.
