Single nucleotide polymorphisms in the mitochondrial displacement loop and age-at-onset of non-small cell lung cancer

W. X. Hu, Ding, C. M., Li, R. J., Fan, H. Y., Guo, Z. J., and Liu, W., Single nucleotide polymorphisms in the mitochondrial displacement loop and age-at-onset of non-small cell lung cancer, vol. 14, pp. 2512-2517, 2015.

The associations between single nucleotide polymorphisms (SNPs) in the displacement loop (D-loop) of mitochondrial DNA (mtDNA) and cancer risk and disease outcome have been extensively analyzed. We investigated the association between age-at-onset and SNPs in the mitochondrial D-loop using a population-based series of non-small cell lung cancer (NSCLC) patients. The D-loop region of mtDNA from NSCLC patients was amplified and sequenced.

Molecular study of Astyanax altiparanae (Osteichthyes, Characidae) as a probable species complex

I. C. Deprá, Gomes, V. N., Deprá, G. C., Oliveira, I. J., Prioli, S. M. A. P., and Prioli, A. J., Molecular study of Astyanax altiparanae (Osteichthyes, Characidae) as a probable species complex, vol. 13, pp. 6015-6026, 2014.

Astyanax altiparanae, belonging to the bimaculatus group, which includes species with similar colors and morphology, occurs in the upper Paraná River basin. As the use of mitochondrial DNA has made great strides in the diagnosis of species, in previous researches, two strains were detected in A. altiparanae with a high divergence in the D-loop region, provisionally called AltoPR and AltoPR-D. Evidence led to the hypothesis that the two strains did not belong to the same species. Phylogenetic hypotheses were produced by maximum-likelihood.

Population structure and demographic history of Sicyopterus japonicus (Perciformes; Gobiidae) in Taiwan inferred from mitochondrial control region sequences

Y. M. Ju, Hsu, C. H., Fang, L. S., Lin, H. D., Wu, J. H., Han, C. C., Chen, I. - S., and Chiang, T. Y., Population structure and demographic history of Sicyopterus japonicus (Perciformes; Gobiidae) in Taiwan inferred from mitochondrial control region sequences, vol. 12, pp. 4046-4059, 2013.

The amphidromous goby Sicyopterus japonicus is distributed throughout southern Taiwan and Japan. Larvae of this freshwater fish go through a long marine stage. This migratory mode influences population genetic structure. We examined the genetic diversity, population differentiation, and demographic history of S. japonicus based on the mitochondrial DNA control region. We identified 102 haplotypes from 107 S. japonicus individuals from 22 populations collected from Taiwan and Islet Lanyu.

Phylogenetic relationships of the Orang Asli and Iban of Malaysia based on maternal markers

K. C. Ang, Leow, J. W. H., Yeap, W. K., Hood, S., Mahani, M. C., and Md-Zain, B. M., Phylogenetic relationships of the Orang Asli and Iban of Malaysia based on maternal markers, vol. 10, pp. 640-649, 2011.

Malaysia remains as a crossroad of different cultures and peoples, and it has long been recognized that studying its population history can provide crucial insight into the prehistory of Southeast Asia as a whole. The earliest inhabitants were the Orang Asli in Peninsular Malaysia and the indigenous groups in Sabah and Sarawak. Although they were the earliest migrants in this region, these tribes are divided geographically by the South China Sea.

mtDNA variation of the critically endangered hawksbill turtle (Eretmochelys imbricata) nesting on Iranian islands of the Persian Gulf

M. Tabib, Zolgharnein, H., Mohammadi, M., Salari-Aliabadi, M. A., Qasemi, A., Roshani, S., Rajabi-Maham, H., and Frootan, F., mtDNA variation of the critically endangered hawksbill turtle (Eretmochelys imbricata) nesting on Iranian islands of the Persian Gulf, vol. 10, pp. 1499-1503, 2011.

Genetic diversity of sea turtles (hawksbill turtle) was studied using sequencing of mitochondrial DNA (mtDNA, D-loop region). Thirty dead embryos were collected from the Kish and Qeshm Islands in the Persian Gulf. Analysis of sequence variation over 890 bp of the mtDNA control region revealed five haplotypes among 30 individuals. This is the first time that Iranian haplotypes have been recorded. Nucleotide and haplotype diversity was 0.77 and 0.001 for Qeshm Island and 0.64 and 0.002 for Kish Island, respectively.

Molecular differentiation of species of the genus Zungaro (Siluriformes, Pimelodidae) from the Amazon and Paraná-Paraguay River basins in Brazil

T. A. Boni, Padial, A. A., Prioli, S. M. A. P., Lucio, L. C., Maniglia, T. C., Bignotto, T. S., Panarari-Antunes, R. S., Prioli, R. A., and Prioli, A. J., Molecular differentiation of species of the genus Zungaro (Siluriformes, Pimelodidae) from the Amazon and Paraná-Paraguay River basins in Brazil, vol. 10, pp. 2795-2805, 2011.

Fish species of the Zungaro genus (Siluriformes, Pimelodidae) are amongst the largest migratory fish in Latin America and have considerable economic importance for commercial fishing in Brazil. However, natural populations of this large catfish are experiencing a severe decline. There are significant taxonomical inconsistencies for this fish. Two geographically separated species of the fish were initially described, one endemic in the Amazon and another in the Paraná-Paraguay River basins.
