L-Carnitine Ameliorates Cancer Cachexia in Mice Partly via the Carnitine Palmitoyltransferase-Associated PPAR-γ Signaling Pathway.
BACKGROUND L-Carnitine has been demonstrated to ameliorate cachectic symptoms. In the present study, we sought to investigate the role of the peroxisome proliferator-activated receptor-γ (PPAR-γ) signaling pathway in the ameliorative effects of L-carnitine on cancer cachexia in a colon-26 tumor-bearing mouse model. METHODS The cachectic mice received L-carnitine (p.o.) or etomoxir (i.p.), or ...
متن کاملThe soluble carnitine palmitoyltransferase from bovine liver
The properties of two carnitine acyltransferases (CPT) purified from bovine liver are compared to confirm that they are different proteins. The soluble CPT and the inner CPT from mitochondria differ in subunit Mr, native Mr, pI and reactivity with thiol reagents. All eight free thiol groups in soluble CPT react with 5,5'dithiobis-(2-nitrobenzoate) in the absence of any unfolding reagent, and ac...
متن کاملInteracting effects of L-carnitine and malonyl-CoA on rat liver carnitine palmitoyltransferase.
Malonyl-CoA significantly increased the Km for L-carnitine of overt carnitine palmitoyltransferase in liver mitochondria from fed rats. This effect was observed when the molar palmitoyl-CoA/albumin concentration ratio was low (0.125-1.0), but not when it was higher (2.0). In the absence of malonyl-CoA, the Km for L-carnitine increased with increasing palmitoyl-CoA/albumin ratios. Malonyl-CoA di...
متن کاملCarnitine palmitoyltransferase II deficiency
The authors investigated 32 patients with the muscle form of CPT II deficiency. Total carnitine palmitoyltransferase enzyme system (CPT) activity was normal but abnormally inhibited by malonyl-CoA, palmitoyl-CoA, and the detergents Triton X and Tween 20. Mutation analysis identified three described mutations (S113L, P50H, and F448L) and two novel mutations (M214T and Y479F). Using modeling tech...
متن کاملStructural model of carnitine palmitoyltransferase I based on the carnitine acetyltransferase crystal.
CPT I (carnitine palmitoyltransferase I) catalyses the conversion of palmitoyl-CoA into palmitoylcarnitine in the presence of L-carnitine, facilitating the entry of fatty acids into mitochondria. We propose a 3-D (three-dimensional) structural model for L-CPT I (liver CPT I), based on the similarity of this enzyme to the recently crystallized mouse carnitine acetyltransferase. The model include...
