The Nile soft-shelled turtle (Trionyx triunguis) is distributed between Dalyan and Samandağ throughout the Mediterranean coast in Turkey. The Mediterranean subpopulation of the Nile soft-shelled turtle is listed as critically endangered in the IUCN Red List Categories. This investigation aimed to determinate levels of genetic variations and patterns of genetic structures among Mediterranean populations in Turkey by using T. triunguis-specific microsatellite primers. A total of 13 polymorphic microsatellite loci were studied among samples of 121 individuals collected from five populations in Turkey. Of 13 polymorphic microsatellite loci used, 3 new were identified in this study. The genetic differentiation among the 5 studied populations of T. triunguis was significant (p 0.001). The analysis of molecular variance (AMOVA) indicated that genetic variations occurred mainly within populations (89.7%) rather than among populations (10.3%). Structure analysis showed presence of two main groups among the Mediterranean T. triunguis populations. However genetic variations among populations were not correlated with geographic distance between the locations. Analysis of data showed that one of the populations (Dalyan) had undergone a bottleneck effect. Migration analysis indicates that T. triunguis migrates between five Mediterranean populations in Turkey. We concluded that based on our results the status of ‘critically endangered’ of T. triunguis should be maintained. Long term population genetic survey studies should be undertaken and changes in habitats of T. triunguis populations, as well as their population size and structure should be monitored for each population to be able to establish a clear strategy for protection of T. triunguis.

Correlation between 13 genetic variations of the glutaminyl-peptide cyclotransferase gene andadjusted aBMD was tested among 384 adult women. Among 13 variations with strong linkage disequilibrium,R54W showed a prominent association (p ? 0.0003), which was more striking when examined among 309 eldersubjects (>50 years; p ? 0.0001). Contribution for postmenopausal bone loss was suggested.Introduction: Alterations in homeostatic regulation of estrogen through the hypothalamus-pituitary-gonadal axis(HPG axis) importantly affect the pathogenesis of osteoporosis. Osteoporosis-susceptibility genes have beenproposed in this hormonal axis, such as estrogen receptor genes and the gonadotropin-releasing hormone gene(GnRH). Here we report another example of genes: glutaminyl-peptide cyclotransferase gene (QPCT), an essentialmodifier of pituitary peptide hormones, including GnRH.Materials and Methods: Analyses of association of 13 single nucleotide polymorphisms (SNPs) at the QPCT locuswith adjusted areal BMD (adj-aBMD) were carried out among 384 adult women. Linkage disequilibrium (LD) wasanalyzed by haplotype estimation and calculation of D? and r2. Multiple regression analysis was applied forevaluating the combined effects of the variations.Results and Conclusions: LD analysis indicated strong linkage disequilibrium within the entire 30-kb region of theQPCT gene. Significant correlations were observed between the genotypes of the six SNPs and the radial adj-aBMD,among which R54W (nt ? 160C?T) presented the most prominent association (p ? 0.0003). Striking associationwas observed for these SNPs among the 309 subjects ?50 years of age (R54W, p ? 0.0001; ?1095T?C, p ?0.0002; ?1844C?T, p ? 0.0002). Multiple regression analyses indicated that multiple SNPs in the gene might actin combination to determine the radial adj-aBMD. These results indicate that genetic variations in QPCT are theimportant factors affecting the BMD of adult women that contribute to susceptibility for osteoporosis. The datashould provide new insight into the etiology of the disease and may suggest a new target to be considered duringtreatment.J Bone Miner
