Abstract
BACKGROUND Knowledge regarding the plasma fatty acid (FA) pattern in patients with liver cirrhosis is fragmentary. OBJECTIVE We evaluated plasma FA lipidome and its association with the prognosis of cirrhosis and severity of liver graft damage after transplantation. DESIGN In this observational study, plasma FA lipidome was investigated in 51 cirrhotic patients before liver transplantation and in 90 age- and sex-matched healthy control subjects. In addition, we studied ischemia-reperfusion damage in the liver of 38 patients for whom a graft biopsy was available at transplantation. With the use of logistic regression, we modeled the presence of cirrhosis, the dichotomized model for end-stage liver disease score below and above the median, and the presence of severe liver graft ischemia-reperfusion damage. RESULTS The FA pattern was markedly altered in cirrhotic patients, who showed, compared with healthy controls, higher monounsaturated FAs, lower n-6 and n-3 polyunsaturated FAs, and undetectable cerotic acid. Plasma di-homo-γ-linolenic acid was independently associated with the presence of cirrhosis (OR: 0.026; 95% CI: 0.004, 0.196; P < 0.0001), severity of its prognosis (OR: 0.041; 95% CI:0.005, 0.376; P = 0.006), postreperfusion graft hepatocellular necrosis (OR: 0.921; 95% CI: 0.851, 0.997; P = 0.043), and sinusoidal congestion (OR: 0.954; 95% CI: 0.912, 0.998; P = 0.039). Associations of di-homo-γ-linolenic acid with the presence of cirrhosis and severity of its prognosis were confirmed also after false discovery rate correction. CONCLUSIONS Cerotic and di-homo-γ-linolenic acids may serve as markers of disease and prognosis in liver cirrhosis. Dietary supplementation with di-homo-γ-linolenic acid could be a reasonable interventional strategy to delay disease progression in liver cirrhosis.

Biochem Pharmacol 2013; 86:548-60. [PMID: 23792120 PMCID: PMC4164904 DOI: 10.1016/j.bcp.2013.06.006] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2013] [Revised: 06/10/2013] [Accepted: 06/10/2013] [Indexed: 12/30/2022]
Abstract
7-Ketocholesterol (7-KC) is found at an elevated level in patients with cancer and chronic liver disease. The up-regulation of an efflux pump, P-glycoprotein (P-gp) leads to drug resistance. To elucidate the effect of 7-KC on P-gp, P-gp function and expression were investigated in hepatoma cell lines Huh-7 and HepG2 and in primary hepatocyte-derived HuS-E/2 cells. At a subtoxic concentration, 48-h exposure to 7-KC reduced the intracellular accumulation and cytotoxicity of P-gp substrate doxorubicin in hepatoma cells, but not in HuS-E/2 cells. In Huh-7 cells, 7-KC elevated efflux function through the activation of phosphatidylinositol 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) pathway. 7-KC activated the downstream protein synthesis initiation factor 4E-BP1 and induced P-gp expression post-transcriptionally. The stimulation of efflux was reversible and could not be prevented by N-acetyl cysteine. Total cellular ATP content remained the same, whereas the lactate production was increased and fluorescence lifetime of protein-bound NADH was shortened. These changes suggested a metabolic shift to glycolysis, but glycolytic inhibitors did not eliminate 7-KC-mediated P-gp induction. These results demonstrate that 7-KC induces P-gp through PI3K/mTOR signaling and decreased the cell-killing efficacy of doxorubicin in hepatoma cells.
