Abstrakt:	Objective: The aim: To evaluate the mRNA expression of the key regulators of osteogenesis - osteocalcin and BMP-2 in the mouse embryos mandible (17th day of pregnancy) which were borne by females on high-cholesterol diet for 30 days before fertilization and throughout pregnancy. Patients and Methods: Materials and methods: Experimental hypercholesterolemia (2%) was simulated by adding Cholesterol to the diet for 60 days. In experiment were used 40 mature female white mice that were randomly divided to control and experimental groups. The control group were fed with standard chow diet, the experimental group with diet with cholesterol enriched diet (with addition of 2 grams of Cholesterol per 100 grams of standard chow). The mandibles of mouse embryos (E-17) were examined by using molecular genetic methods. Results: Results: In control group the relative level of BMP-2 mRNA / actin mRNA was 27.0«2.82, the relative level of and osteocalcin mRNA / actin mRNA was 30.5«6,28. In the jaws of animals in the experimental group with cholesterol enriched diet, the expression relative level of BMP-2 was 30.9«5.81 that is by 14,4% higher than in control group. Therefore, the expression level of оsteocalcin, on the contrary, decreased by 22.3% and was 23.7+5.31. Conclusion: Conclusions: Our study report influence of the cholesterol enriched diet (2%) on mRNA expression of BMP-2 and osteocalcin encoding genes. The embryos from mouse on cholesterol enriched diet (2%) had increased level of BMP-2 gene expression, however significantly decreased level of osteocalcin gene expression.
