[Beta3-adrenergic receptor].

The beta3-adrenergic receptor (beta3-AR) may play a key role in the regulation of lipid metabolism and glucose homeostasis. Adrenaline and noradrenaline beta3-AR stimulate lipolysis and thermogenesis in human fat cells and increase glucose uptake in skeletal muscle. Therefore, the beta3-AR gene may be associated with obesity and related diseases, such as type 2 diabetes, coronary heart disease and hypertension.

[Practical usefulness of the IDENTIFILER system for paternity testing in the Central Poland population].

The usefulness of the IDENTIFILER multiplex system for paternity testing in the Central Poland population was examined. One hundred excluding cases and one hundred including cases were analysed and the results were estimated for two different types of cases: trios (standard cases) and duos (motherless cases). Efficiency of exclusion and paternity index were analysed for each locus as well as for the entire set of the fifteen STR markers.

An association between the Trp64Arg polymorphism in the beta3-adrenergic receptor gene and endometrial cancer and obesity.

Beta3-adrenergic receptor (beta3AR) stimulates lipolysis in human fat cells, so its gene can constitute a candidate to explain a part of genetic predisposition to human obesity and related disorders. The Trp64Arg polymorphism in the beta3AR gene has been reported to be associated with insulin resistance, obesity and type 2 diabetes; little is known about its possible association with cancer. To check this association we determined the distribution of its genotypes and frequency of alleles in endometrial cancer patients with or without overweight/obesity as compared to appropriate controls.

[Allele distribution of the ten STR loci in Central Poland population].

Allele frequency data for ten STR loci: D3S1358, vWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, TH01, FGA were estimated in a sample of 350 unrelated individuals in Central Poland population (Lodz region). The accordance with the Hardy and Weinberg equilibrium (HWE) for all investigated loci was proved. The allele distributions were compared to the similar data for other populations.
