In this investigation associations of gene complexes consisting of seven candidate for coronary atherosclerosis (ACE, AGT, NOS3, APOA1, MTHFR, PLAT, F13) with risk factors for CAD (lipid levels, blood pressure, body mass index (BMI)) were studied in Russian population. 94 male patients with CAD proven by angiography and 131 healthy individuals were involved in the case-control study. We observed a significant contribution of gene combinations ("ensembles"). ACE-MTHFR, ACE-F13, ACE-AGT-MTHFR in the variability of the total cholesterol and LDL-cholesterol levels. The "Ensembles" ACE-AGT-MTHFR were associated with variability of three atherogenic risk factors (LDL, BMI, cholesterol total). Two-locus gametic disequilibrium was analysed between gene polymorphisms. NOS3 and ACE, NOS3 and APOA1 were in gametic disequilibrium in the control group. Polymorphic markers of ACE and F13, NOS3 and F13, ACE and PLAT loci were in gametic disequilibrium in the patients. Both approaches (association analysis and gametic disequilibrium) revealed the same gene combinations contributing to the CAD risk factors. NOS3 and APOA1 markers were in gametic disequilibrium in the patients and both of them were associated with LDL. F13 and AGT were associated with systolic and diastolic blood pressure and two-locus gametic disequilibrium between F13 and AGT polymorphisms observed in the patients.

The following seven polymorphic marker loci of genes responsible for predisposition to coronary atherosclerosis (CAS) were studied: the ACE locus responsible for angiotensin-converting enzyme insertion/deletion polymorphism for the presence or absence of the Alu insertion in the gene; the F13, PLAT, and APOA1 loci, controlling the clotting factor 13, plasminogen-activating tissue factor, and apolipoprotein A, respectively; the MTHFR and AGT polymorphic loci responsible for point mutations in methylenetetrahydrofolate reductase and those in angiotensinogen, respectively, and the NOS3 locus controlling the number of tandem repeats in the nitric oxide synthase gene. These loci are located on different chromosomes and encode products involved into various metabolic pathways leading to CAS. In the populations studied, significant differences between healthy subjects and patients predisposed to cardiovascular diseases were revealed with regard to the above seven markers. The 174M allele (T174M polymorphism in the ACE gene) was significantly associated with coronary atherosclerosis. It was found that specific gene combinations are involved in the CAS development and determine variation in the pathogenetically important quantitative traits.

During the oestrous cycle, the bovine endometrium exhibits characteristic morphological and functional changes, which are mainly induced by progesterone (P(4)), oestrogens and oxytocin. We studied the response of the endometrium to this changing hormonal environment at the transcriptome level using a custom-made cDNA microarray. Endometrium samples were recovered from Simmental heifers on days 0 (oestrus), 3.5 (metoestrus), 12 (dioestrus) and 18. The latter group was divided into animals with high (late dioestrus) and low P(4) levels (preoestrus). Significance analysis of microarrays revealed 269 genes exhibiting significant changes in their transcript levels during the oestrous cycle in distinct temporal patterns. Two major types of expression profiles were observed, which showed the highest mRNA levels during the oestrus phase or the highest levels during the luteal phase respectively. A minor group of genes exhibited the highest mRNA levels on day 3.5. Gene ontology (GO) analyses revealed GO categories related to extracellular matrix remodelling, transport, and cell growth and morphogenesis enriched at oestrus, whereas immune response and particular metabolic pathways were overrepresented at dioestrus. Generation of gene interaction networks uncovered the genes possibly involved in endometrial remodelling (e.g. collagen genes, TNC, SPARC, MMP2, MEP1B, TIMP1, TIMP2, HTRA1), regulation of angiogenesis (e.g. ANGPTL2, TEK, NPY, AGT, EPAS1, KLF5 ), regulation of invasive growth (e.g. PCSK5, tight junction proteins, GRP, LGALS1, ANXA2, NOV, PLAT, MET, TDGF1, CST6, ITGB4), cell adhesion (e.g. MUC16, LGALS3BP) and embryo feeding (e.g. SLC1A1, SLC11A2, SLC16A1, SEPP1, ENPP1). Localisation of mRNA expression in the endometrium was analysed for CLDN4, CLDN10, TJP1, PCSK5, MAGED1, and LGALS1.
