Arterial hypertension (AH) belongs to the diseases with genetic predisposition that determines the necessity of research on the genetic component’s influence on this disease development. It is suggested that one of the salt-sensitive arterial hypertension potential markers may be the alpha-adducin gene because its protein product is involved in the ion transport regulation in the renal epithelium. Thus, the aim of the study was to investigate the association between ADD1 Gly460Trp-polymorphism and the AH development risk among patients with different risk factors in the Ukrainian population. The study included 232 Ukrainians: 120 patients with diagnosed arterial hypertension and 112 practically healthy individuals. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was used for ADD1 Gly460Trp-polymorphism genotyping. The ADD1 Gly460Trp-polymorphic locus is an important predictor of arterial hypertension development in the Ukrainian population, but other nongenetic factors should be considered in further studies.

AbstractStress syndrome is usually caused by a mutation in theryanodine receptorgene(ryr1) and it is widely studied in humans and swine populations. The protein product of this gene plays a crucial role in the regulation of calcium transport in muscle cells. A G>T mutation in the humanryr1gene, which results in the replacement of a conserved arginine at position 614 where a leucine occurs at the same position as the previously identified Arg→Cys mutation reported in all cases of porcine stress syndrome (PSS). Porcine stress syndrome affects biochemical pathways in stress-susceptible individuals during a stress episode and some biochemical parameters that were used as markers for diagnostic purposes. Also, PSS has remarkable influence on the maternal characteristics of sows. This study dealt with different genotypes for PSS and its association with possible biochemical changes and maternal traits of sows. Seventy-three reproductive sows genotyped for PSS by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were included in this survey. Sixty of them were stress-free (NN), 11 were heterozygous carriers (Nn) and two animals were homozygous (nn) for the 1843 (C>T) mutation. Significant differences in non stress induced animals with different PSS genotypes were found in the values of creatine phoshokinase (CPK), lactate dehydrogenase (LDH), alkaline phosphatase (AP) and aspartate aminotransferase (AST). Regarding the maternal traits, our study showed that stress susceptible animals (nn) have an increased number of stillborn piglets and a reduced number of newborn piglets compared with heterozygous and normal animals.

A study was conducted to identify the polymorphism in the intron 3 of the Growth Hormone (GH) gene and also to evaluate the association of the GH gene polymorphism with growth parameters and dressing percentage in the Sumba Ongole (SO) cattle. A total of 267 individual DNA samples were used in the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. The SO cattle growth parameters data (n=44) including birth weight (BW), weaning weight at 205 days of age (WW205), yearling weight at 365 days of age (YW365) and also dressing percentage (DP) (n=122) were investigated in this study. There were three genotypes (AA, AB, and BB) of the GH gene based on the PCR-RFLP analysis with allele frequency was 0.87 and 0.13 for A allele and B allele respectively. The highest genotype frequency in the SO cattle is AA (0.76) and the lowest is BB (0.02). The Heterozygosity Observed (Ho) value in the SO cattle population is 0.23 and Polymorphism Information Content (PIC) value is 0.20. Therefore, the genetic diversity in the SO cattle based on the GH gene polymorphism is quite low. There is no association (P>0.05) in BW, WW205, YW365, and DP with genotypes of the GH gene. As the result, the GH gene in this study cannot be used as a genetic marker in the SO cattle breeding program.

Background: Matrix metalloproteinases (MMPs) are upregulated in tumors. The MMP-7 A-181G polymorphism is associated with increased expression of the MMP-7 gene. Aim of the present study was to investigate the association between the MMP-7 A-181G polymorphism and susceptibility to breast cancer. Patients and Methods: The MMP-7 A-181G variants were studied in a cohort of 251 subjects consisting of 100 breast cancer patients and 151 healthy controls; all were from Western Iran. The MMP-7 A-181G genotypes were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Results: The frequencies of the MMP-7 AA, AG, and GG genotypes in healthy individuals were 34.4, 50.4, and 15.2%, respectively. In breast cancer patients, the frequencies of AA (34%), AG (52%), and GG (14%) genotypes (p = 0.95) were similar to those in the controls. There was a trend toward an increased frequency of the combined genotype of MMP-7 AG+GG in patients with lymph node metastasis (70.4%) compared to those without metastasis (66.7%). Also, in patients with invasive lobular carcinoma, the frequency of the MMP-7 AG+GG genotype tended to be higher (71.4%) compared to that in patients with invasive ductal carcinoma (66.2%) (p = 0.78). Conclusion: Our findings indicate that the MMP-7 A-181G polymorphism may not be correlated with susceptibility to breast cancer in our population.

Sugarcane Mosaic Disease

Sugarcane leaves with mosaic symptoms were collected in 2006–07 in Tucumán (Argentina) and analyzed by reverse-transcriptase polymerase chain reaction (RT-PCR) restriction fragment length polymorphism (RFLP) and sequencing of a fragment of the Sugarcane mosaic virus (SCMV) and Sorghum mosaic virus (SrMV) coat protein (CP) genes. SCMV was detected in 96.6% of samples, with 41% showing the RFLP profile consistent with strain E. The remaining samples produced eight different profiles that did not match other known strains. SCMV distribution seemed to be more related to sugarcane genotype than to geographical origin, and sequence analyses of CP genes showed a greater genetic diversity compared with other studies. SrMV was detected in 63.2% of samples and most of these were also infected by SCMV, indicating that, unlike other countries and other Argentinean provinces, where high levels of co-infection are infrequent, co-existence is common in Tucumán. RFLP analysis showed the presence of SrMV strains M (68%) and I (14%), while co-infection between M and H strains was present in 18% of samples. Other SCMV subgroup members and the Sugarcane streak mosaic virus (SCSMV) were not detected. Our results also showed that sequencing is currently the only reliable method to assess SCMV and SrMV genetic diversity, because RT-PCR-RFLP may not be sufficiently discriminating.
