Visceral and subcutaneous adipose depots have different metabolic roles that may be involved in the development of obesity-related pathologies. Procyanidins have beneficial effects on insulin resistance, and they target adipose tissue. We analyse whether procyanidins exert different effects, depending on the adipose tissue depot, and whether these effects show a relation to the amount of phenolic compound in the tissue. We studied the effects of a grape seed procyanidin extract (GSPE) treatment at the transcriptional level on genes expressed differentially between mesenteric and subcutaneous adipose tissue depots and genes previously shown to be targets of procyanidins. Procyanidins target mesenteric adipose tissue in Wistar lean rats but subcutaneous adipose tissue in Zucker obese rats. Non-modified structures also accumulated, preferentially in the same respective tissues that were responsive to GSPE. Thus, procyanidins target and accumulate differently in mesenteric and subcutaneous adipose tissue depots, depending on the metabolic condition of the animal model.

UI MeSH Term Description Entries
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).
D011924 Rats, Zucker Two populations of Zucker rats have been cited in research--the "fatty" or obese and the lean. The "fatty" rat (Rattus norvegicus) appeared as a spontaneous mutant. The obese condition appears to be due to a single recessive gene. Zucker Rat,Zucker Rats,Rat, Zucker
D005260 Female Females
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015870 Gene Expression The phenotypic manifestation of a gene or genes by the processes of GENETIC TRANSCRIPTION and GENETIC TRANSLATION. Expression, Gene,Expressions, Gene,Gene Expressions
D017208 Rats, Wistar A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain. Wistar Rat,Rat, Wistar,Wistar Rats
D044945 Proanthocyanidins Dimers and oligomers of flavan-3-ol units (CATECHIN analogs) linked mainly through C4 to C8 bonds to leucoanthocyanidins. They are structurally similar to ANTHOCYANINS but are the result of a different fork in biosynthetic pathways.

D050152 Intra-Abdominal Fat Fatty tissue inside the ABDOMINAL CAVITY, including visceral fat and retroperitoneal fat. It is the most metabolically active fat in the body and easily accessible for LIPOLYSIS. Increased visceral fat is associated with metabolic complications of OBESITY.
