Association of the T54 allele of the FABP2 gene with cardiovascular risk factors in obese Mexican subjects.

Genetic predisposition to cardiovascular risk may vary between different ethnic groups. We studied the effect of the FABP2 A54T polymorphism on biochemical and anthropometric cardiovascular risk factors in 114 obese Mexican subjects. The mean age of the patients studied was 36.

Influence of the -308 TNF-alpha and -174 IL-6 polymorphisms on lipid profile in Mexican subjects.

Polymorphisms in the promoter region of several cytokine genes have been associated with differential cytokine production. Several reports indicate that polymorphisms in the tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) genes are associated with lipid abnormalities. The aim of this study was to identify the genotype frequencies for -308G/ATNF-alpha and -174G/CIL-6 polymorphisms in Mexican subjects and to determine the influence of both polymorphisms on serum lipid levels.

Genetic predisposition of cholesterol gallstone disease.

Gallstone disease (GSD) is the result of the interaction between genetic and environmental factors and it is a major disease cause of surgery with high costs to health systems. Worldwide prevalence varies according to the ethnic population suggesting that high prevalence of GSD in certain ethnic groups is due to the presence of genetic factors implicated in different metabolic pathways. However, environmental factors play a determinant role in gene expression.

Routes of infection and clinical outcome of Mexican women reactive to anti-hepatitis C virus antibodies.

Background: Risk factors for the hepatitis C virus (HCV) infection influence both the frequency and the progression of the liver disease. Routes of transmission and severity of the liver damage may differ by gender. We aimed to describe the risk factors for HCV infection and for the severity of the liver disease among women seroreactive to anti-HCV antibodies.

The role of FABP2 gene polymorphism in alcoholic cirrhosis.

Hypertriglyceridemia and dietary lipids have been suggested to modulate the severity of alcoholic liver disease and the progression to alcoholic cirrhosis (AC). The intestinal fatty acid binding protein (IFABP) is the main transporter of dietary fatty acids into the enterocyte and has a genetic polymorphism, FABP2 A54T that has been associated with hypertriglyceridemia. We determined the frequency of the FABP2 gene polymorphism using PCR-RFLP and measured serum triglycerides, HDL, LDL, total lipids and cholesterol in 67 patients with AC and in 124 unrelated healthy individuals.

Expression of apolipoprotein AI mRNA in peripheral white blood cells of patients with alcoholic liver disease.

Because (i) changes in plasma and liver mRNA of apolipoprotein (apo) AI have been observed in patients with alcoholic liver disease, (ii) apo AI mRNA can be induced in non-hepatic tissues, and (iii) apolipoproteins expression is influenced by plasma colloid osmotic pressure (P(CO)) and viscosity (eta), we analyzed the Apo AI mRNA expression in the peripheral white blood cells (PWBC), P(CO), and eta in control volunteers (C), patients with liver cirrhosis (LC), and cirrhotic patients with superimposed alcoholic hepatitis (LC+AH). We found that apo AI mRNA is expressed in the PWBC in 20% of C and it is induced 1.5 fold in 66.

Albumin mRNA in peripheral white blood cells of cirrhotic patients with a superimposed alcoholic hepatitis is associated to fatal outcome.

The aim of this study was to analyze the relationship of plasma colloid osmotic pressure (COP), relative viscosity (eta) and overall outcome on the expression of albumin (ALB) mRNA in peripheral white blood cells (PWBC) of cirrhotic patients with superimposed alcoholic hepatitis (LC+AH). ALB messanger was detected in PWBC by RT-nPCR in control individuals (C), patients with liver cirrhosis (LC) and LC+AH. A higher number of LC+AH patients were positive to ALB mRNA (67%), compared to C (30%) and LC (28%).
