Thiourea enhances mapping of the proteome from murine white adipose tissue. Proteomics, 2001, Volume: 1, Issue:7 Adipose tissue imposes problems in two-dimensional (2-D) analysis due to its extremely high content of fat. To improve protein separation detergents and chaotropes were varied in the IEF step. The most important factor for obtaining distinct spots in the 2-D gel was whether thiourea was included or not. Many high molecular weight spots became resolved by using thiourea, while no spots disappeared or showed inferior characteristics, thus approximately twice as many spots were possible to quantify. Hydrophobic indices were compared for a set of proteins that gave rise to sharper spots with proteins that were not improved on the use of thiourea. The comparison did not give any statistically significant difference between the two groups of proteins. One of the effects obtained by inclusion of thiourea was that the dominating protein, serum albumin, appeared as more condensed spots allowing other minor proteins to be detected. This work resulted in a protocol which greatly enhances the resolution of proteins in adipose tissue. A 2-D map of mouse white adipose tissue from epididymal fat pads was constructed in which 140 spots were identified by mass spectrometry. This work lays the ground for our further studies on white adipose tissue in metabolic diseases such as obesity and dyslipidemia.

Hyperlipemic responses induced by centrally administered histamine H1- and H2-receptor agonists in rats. Agents and actions, 1987, Volume: 20, Issue:3-4 The H1-receptor agonist 2-pyridylethylamine (PEA), and the H2-receptor agonists dimaprit and impromidine administered intracerebroventricularly (i.c.v.) to conscious rats considerably increased the concentration of free fatty acids (FFA) in the blood serum. The hyperlipemic effect of PEA was abolished by mepyramine, a H1-receptor antagonist. Responses to dimaprit and impromidine were not antagonized by cimetidine. These results suggest that central H1-receptor stimulation elicits the hyperlipemic responses in rats. The role of central H2-receptors in this reaction is not clear.

Hyperlipemic responses induced by centrally administered histamine H1- and H2-receptor agonists in rats.

Agents and actions, 1987, Volume: 20, Issue:3-4

The H1-receptor agonist 2-pyridylethylamine (PEA), and the H2-receptor agonists dimaprit and impromidine administered intracerebroventricularly (i.c.v.) to conscious rats considerably increased the concentration of free fatty acids (FFA) in the blood serum. The hyperlipemic effect of PEA was abolished by mepyramine, a H1-receptor antagonist. Responses to dimaprit and impromidine were not antagonized by cimetidine. These results suggest that central H1-receptor stimulation elicits the hyperlipemic responses in rats. The role of central H2-receptors in this reaction is not clear.
