Fat accumulation is associated with the release of many novel adipokines such as retinol-binding protein 4 and fatty acid-binding protein 4. These adipokines have been linked to insulin resistance, metabolic syndrome, type 2 diabetes and cardiovascular disease. Since weight loss is the first step for the treatment of metabolic syndrome, which increases the risks for both type 2 diabetes and cardiovascular disease, we have investigated the effects of weight loss on serum retinol-binding protein 4 and fatty acid-binding protein 4 in obese individuals with this syndrome. Twenty-nine obese female subjects with metabolic syndrome, aged 18-62 years completed a 2-month weight loss diet plan. Data were collected from dual-energy X-ray absorptiometry and indirect calorimetry. Blood was taken at baseline and at 2 months and assayed for adipokines, lipids, and insulin resistance parameters. The change in circulating fatty acid-binding protein 4 levels were inversely correlated with total weight loss (p<0.02) and lean mass loss (p<0.01), but not with fat mass loss. Retinol-binding protein 4 levels did not track with any measure of body composition. Changes in leptin levels were found to correlate with weight loss (p<0.02), fat loss (p<0.03), and lean mass loss (p<0.05). Fatty acid-binding protein 4 levels increased and retinol-binding protein 4 levels did not change during moderate weight loss in obese women with metabolic syndrome; however, several other risk factors for type 2 diabetes and cardiovascular disease did improve with weight loss.

UI	MeSH Term	Description	Entries
D007333	Insulin Resistance	Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS.	Insulin Sensitivity,Resistance, Insulin,Sensitivity, Insulin
D009765	Obesity	A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D000886	Anthropometry	The technique that deals with the measurement of the size, weight, and proportions of the human or other primate body.
D015415	Biomarkers	Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, ENVIRONMENTAL EXPOSURE and its effects, disease diagnosis; METABOLIC PROCESSES; SUBSTANCE ABUSE; PREGNANCY; cell line development; EPIDEMIOLOGIC STUDIES; etc.	Biochemical Markers,Biological Markers,Biomarker,Clinical Markers,Immunologic Markers,Laboratory Markers,Markers, Biochemical,Markers, Biological,Markers, Clinical,Markers, Immunologic,Markers, Laboratory,Markers, Serum,Markers, Surrogate,Markers, Viral,Serum Markers,Surrogate Markers,Viral Markers,Biochemical Marker,Biologic Marker,Biologic Markers,Clinical Marker,Immune Marker,Immune Markers,Immunologic Marker,Laboratory Marker,Marker, Biochemical,Marker, Biological,Marker, Clinical,Marker, Immunologic,Marker, Laboratory,Marker, Serum,Marker, Surrogate,Serum Marker,Surrogate End Point,Surrogate End Points,Surrogate Endpoint,Surrogate Endpoints,Surrogate Marker,Viral Marker,Biological Marker,End Point, Surrogate,End Points, Surrogate,Endpoint, Surrogate,Endpoints, Surrogate,Marker, Biologic,Marker, Immune,Marker, Viral,Markers, Biologic,Markers, Immune

D050556	Fatty Acid-Binding Proteins	Intracellular proteins that reversibly bind hydrophobic ligands including: saturated and unsaturated FATTY ACIDS; EICOSANOIDS; and RETINOIDS. They are considered a highly conserved and ubiquitously expressed family of proteins that may play a role in the metabolism of LIPIDS.
