The aim of present study was to investigate myostatin gene polymorphism and its association with yearling weight records in Zel sheep using PCR-RFLP and PCR-SSCP methods. Blood samples were collected from 200 Zel sheep, randomly, and DNA was extracted using modified salting out method. Polymerase chain reaction was carried out to amplify 337, 222, and 311 bp fragments, respectively, comprising a part of exon 3, intron 1, and intron 2 of myostatin gene. In addition, exon 3 was digested by HaeIII enzyme under RFLP method, and introns 1 and 2 were studied using SSCP. Under RFLP method, all samples showed mm genotype. Under SSCP method, intron 1 was also monomorph but intron 2 was polymorph (AA, AB, and BB). The allelic frequencies for A and B were 75.5 and 24.5%, respectively. This locus was not in Hardy-Weinberg equilibrium (P<0.05), and there was no significant effect of myostatin gene on yearling weights.

Abstract To investigate the differences between the lineages of the Czech Fleckvieh cattle in Leptin promoter SNP C963T, 695 Czech Fleckvieh cows (650 from production herds and 45 from the Genetic Resources Program (GR)) were examined using PCR-RFLP. The C and T alleles of Leptin promoter were observed with a predominance of C allele in both groups. The most frequent genotypes were CC (63%) in production herds and CT (48%) in the GR population. The present study describes, for the first time, the genetic differences in production herds and GR population in Leptin promoter C963T SNP. Variation within the Czech Fleckvieh population was observed and resulted in an advantage to the GR population. Results presented herein emphasized the importance of the GR program as a reservoir of genetic diversity for indigenous breeds.

Background: The development of local sheep breeds that have high fecundity levels, high meat content and high growth rates would help satisfy the Palestinian demand of meat and lower its price. It has been reported that mutant alleles of the genes Booroola fecundity (FecB), Callipyge (CLPG) and calpastatin (CAST) are associated with high litter size, larger muscular rumps and higher tenderness of meat after sheep slaughter, respectively. PCR-RFLPs methods have been established to facilitate the survey of sheep breeds for such mutants.Methods: In this study, 117 blood samples of the most common sheep breed in Palestine, Assaf, were collected from Bethlehem and Jenin districts. Genomic DNA was extracted and purified from the blood samples using the salting out method. The genotypic ratios and allelic frequencies of the FecB, CLPG and CAST genes were determined by PCR-RFLP method. Result: The results show that the mutant allele B of the FecB gene has a very low frequency among the screened sheep with 0.01 in Bethlehem and 0.07 in Jenin. Also, 94.4% of the tested sheep have the wildtype genotype AA for the CLPG gene with a frequency of 0.95 for allel A. Moreover, the desired heterzygous genotype MN for the CAST gene is 38.4% with an allelic frequency of 0.81 for the mutant allel M. These results would assist establishing sheep breeding programs with the appropriate parental genotypes to improve the livestock sector in the country.

The aim of this study was to identify the polymorphism of leptin gene and its association with growth traits in Kebumen Ongole Grade cattle. One hundred blood samples were collected for molecular analysis. Polymorphism of the leptin gene was analyzed using Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) with HpyCH4V restriction enzyme and DNA sequencing. Association analysis of the leptin gene with growth traits was analyzed by T-test. The results showed that SNP g. 1180 C>T was found in the population.The SNP changed amino acid from arginine to cysteine. The SNP was significantly associated with a high chest circumference at weaning age in animal having CC genotype (P<0.05). There were two identified alleles, namely C and T, with frequencies were 0.885 and 0.115,respectively. The genotype frequencies of CC, CT and TT were 0.78, 0.21 and 0.01, respectively. Allelic and genotypic distribution in the studied population were in Hardy-Weinbergequilibrium. Animals with CC genotype had a higher circumference at weaning age (WCC) than those with CT genotype. In conclusion, SNP g. 1180 C> T in the leptin gene is potential as genetic marker for growth traits in Kebumen Ongole Grade cattle.

It is estimated that about 15% of couples concern with the inability to conceive after 1 year of unprotected intercourse. Genetic and environmental factors play important roles in male infertility. MTHFR (Methylene Tetrahydro Folate Reductase) is encoded by a gene which maps to human chromosome 1p36.22. The c.677C>T mutation causes an amino - acid change of Alanine to Valine (Ala222Val) in exon 4 which is related to oligospermia and azoospermia. Our purpose was to investigate the association of rs1801133 in MTHFR gene with azoospermia and also genetic diversity of some Iranian folks. Peripheral blood samples of 100 men suffered from azoospermia and 55 controls collected from Infertility Clinic of Jihad-university of Qom. DNA was extracted by salting-out method and SNP-Genotyping was performed by PCR-RFLP technique and sequencing. Furthermore, statistical and population genetics analysis were done. The rs1801133 showed no significant relation with azoospermia according to statistical analysis. Furthermore, population genetics analysis showed that there is no genetic differentiation between Turk and Fars ethnics and case and control individuals. MTHFR studied SNP has no significant relation with azoospermia infertility, although further studies on more samples are demanded.

AbstractObjectivesCytochromes P450 play a role in human drugs metabolic pathways and their genes are among the most variable in humans. The aim of this study was to analyze genotype frequencies of five common polymorphisms of cytochromes P450 in Roma/Gypsy and Czech (non-Roma) population samples with Czech origin.MethodsRoma/Gypsy (n=302) and Czech subjects (n=298) were genotyped for CYP1A2 (rs762551), CYP2A6 (rs4105144), CYP2B6 (rs3745274) and CYP2D6 (rs3892097; rs1065852) polymorphisms using PCR-RFLP or Taqman assay.ResultsWe found significant allelic/genotype differences between ethnics in three genes. For rs3745274 polymorphism, there was increased frequency of T allele carriers in Roma in comparison with Czech population (53.1 vs. 43.7%; p=0.02). For rs4105144 (CYP2A6) there was higher frequency of T allele carriers in Roma in comparison with Czech population (68.7 vs. 49.8%; p<0.0001). For rs3892097 (CYP2D6) there was more carriers of the A allele between Roma in comparison with Czech population (39.2 vs. 38.2%; p=0.048). Genotype/allelic frequencies of CYP2D6 (rs1065852) and CYP1A2 (rs762551) variants did not significantly differ between the ethnics.ConclusionsThere were significant differences in allelic/genotype frequencies of some, but not all cytochromes P450 polymorphisms between the Czech Roma/Gypsies and Czech non-Roma subjects.

Circulating Levels

There is evidence that high circulating levels of IL-6 and IL-8 are markers of a poor prognosis in various types of cancer, including NB. The participation of these cytokines in the tumor microenvironment has been described to promote progression and metastasis. Our objective was to evaluate the prognostic role of genetic polymorphisms and serum levels of IL-6 and IL-8 in a cohort of Mexican pediatric patients with NB. The detection of the SNPs rs1800795 IL-6 and rs4073 and rs2227306 IL-8 was carried out by PCR-RFLP and the levels of cytokines were determined by the ELISA method. We found elevated circulating levels of IL-8 and IL-6 in NB patients compared to the control group. The genotype frequencies of the rs1800795 IL-6 and rs4073 IL-8 variants were different between the patients with NB and the control group. Likewise, the survival analysis showed that the GG genotypes of rs1800795 IL-6 (p = 0.014) and AA genotypes of rs4073 IL-8 (p = 0.002), as well as high levels of IL-6 (p = 0.009) and IL-8 (p = 0.046), were associated with lower overall survival. We confirmed the impact on an adverse prognosis in a multivariate model. This study suggests that the SNPs rs1800795 IL-6 and rs4073 IL-8 and their serum levels could be promising biomarkers of a poor prognosis, associated with overall survival, metastasis, and a high risk in Mexican children with NB.

Macadamia is a recently domesticated Australian native nut crop, and a large proportion of its wild germplasm is unexploited. Aiming to explore the existing diversity, 247 wild accessions from four species and inter-specific hybrids were phenotyped. A wide range of variation was found in growth and nut traits. Broad-sense heritability of traits were moderate (0.43–0.64), which suggested that both genetic and environmental factors are equally important for the variability of the traits. Correlations among the growth traits were significantly positive (0.49–0.76). There were significant positive correlations among the nut traits except for kernel recovery. The association between kernel recovery and shell thickness was highly significant and negative. Principal component analysis of the traits separated representative species groups. Accessions from Macadamia integrifolia Maiden and Betche, M. tetraphylla L.A.S. Johnson, and admixtures were clustered into one group and those of M. ternifolia F. Muell were separated into another group. In both M. integrifolia and M. tetraphylla groups, variation within site was greater than across sites, which suggested that the conservation strategies should concentrate on increased sampling within sites to capture wide genetic diversity. This study provides a background on the utilisation of wild germplasm as a genetic resource to be used in breeding programs and the direction for gene pool conservation.
