1 Peroxisome proliferator-activated receptor alpha plays a crucial role in L-carnitine anti-apoptosis effect in renal tubular cells. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
2 We found that the activity of the potential PGI(2) nuclear receptor, peroxisome proliferator-activated receptor alpha (PPARalpha), was elevated by L-carnitine treatment. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
3 We found that the activity of the potential PGI(2) nuclear receptor, peroxisome proliferator-activated receptor alpha (PPARalpha), was elevated by L-carnitine treatment. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
4 The siRNA-mediated blockage of PPARalpha considerably reduced the anti-apoptotic effect of L-carnitine. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
5 In PPARalpha-deficient mice, L-carnitine treatment also lost the inhibitory effect on gentamicin-induced apoptosis in kidneys. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
6 CONCLUSIONS: Based on these findings, we suggest that L-carnitine protects renal tubular cells from gentamicin-induced apoptosis through PGI(2)-mediated PPARalpha activation. Carnitine peroxisome proliferator activated receptor alpha Mus musculus
