Objectives. The environmental and lifestyle conditions of the Kola Sami could have influenced the population-specific frequencies of the AGXT Pro11Leu allele, and certain alleles of APOE and LCT genes, involved respectively, in the metabolism of animal proteins, lipids and milk sugar. Study Design. DNA samples were collected from the Sami population of Lovozero settlement (Murmansk Region) in 00. Methods. The analysis of the traditional diet of the Kola Sami was made using the data of ethnographic studies conducted in the nineteenth and beginning of the twentieth centuries. Frequencies of the AGXT Pro11Leu, APOE*e4 alleles and LCT gene CC-1910 genotype were defined by molecular-genetic analysis. Results. The specificity of the Kola Sami gene pool is in the lower frequency of АРОЕ*e4 allele compared with the Sami of Finland (0.0 and 0.10, respectively) and when compared with other groups (except the Skolt) in the higher frequency of hypolactasia conditioned by the CC-1910 genotype of the LCT gene (0.8). Conclusions. The high prevalence of the AGXT allele T bearers among Kola Sami (0.7) does not contradict the hypothesis of the adaptive role this allele plays in populations with a traditionally high intake of meat.
The goal of this study was to analyze the relationship of the blood serum apolipoprotein E (apoE), total cholesterol (TC), triglycerides (TG), and high and low density lipoproteins (HDLP, LDLP) levels with the body mass index (BMI), relative body surface area (RBSA), and the body muscle (BM) and body fat (BF) amounts. The study was carried out in male and female subjects aged 14-16 years (adolescent age group 1: n 1 M = 141, n 1 F = 151) and 18-25 years (young adult group 2: n 2 M = 141, n 2 F =46). No significant correla tions of serum TG and HDL with the somatometric indices were found. The TÑ content is positively corre lated with the fat component (r 1 = 0.164; r 2 = 0.418) and negatively, with the muscle component of body com position (r 1 = -0.165; r 2 = -0.352) in female subject samples. Blood serum apoE is significantly correlated with body composition (r 1 = -0.168 for BF; r 1 = 0.266, p < 0.05 for BM) in female adolescent subjects. These correlations are significant (p < 0.06) in male subjects aged 14-16 years. The TC and LDLP contents are neg atively correlated with RBSA (r 2 = -0.386 and -0.377, respectively) and positively correlated with BMI (r 2 = 0.413 and 0.415, respectively; p < 0.05) in young adult female subjects. With age, correlations between the fat content and apoE concentration change in female subject samples. The content of apoE decreases with increasing BF in female subjects aged 14-15 years; the correlation disappears in the age interval from 16 to 17 years. An increase in BF is accompanied by an increase in the apoE concentration in female subjects aged 18-19 years and older.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
