Sequence variation and molecular evolution of BMP4 genes.
Authors: D.J. Zhang, J.H. Wu2,, G. Husile, H.L. Sun and W.G. Zhang.
Bone morphogenetic protein 4 (BMP4) regulates skeletogenesis, osteoblastic differentiation, and the induction of hair follicles. Its protein-coding region contains a signal peptide, prodomain (which regulates post-translational synthesis), and a mature domain (which mediates gene function). Previous studies considered this gene to be conserved. By reanaly.. Read More»

Polymorphism of MyoD1 and Myf6 genes and associations with carcass and meat quality traits in beef cattle
Authors: X.H. Du, Q.F. Gan, Z.R. Yuan, X. Gao, L.P. Zhang, H.J. Gao,J.Y. Li and S.Z. Xu1
Myogenic determination factor 1 (MyoD1) and myogenic factor 6 (Myf6) genes belong to the myogenic differentiation (MyoD) gene family, which play key roles in growth and muscle development. The study aimed to investigate the effects of variants in cattle MyoD1 and Myf6 on carcass and meat traits. We screened single nucleotide polymorphisms (SNPs) of both g.. Read More»

MULTINDELS-BOV: Zebu traceback method based on DNA insertion-deletion polymorphisms
Authors: M. Groenner-Penna1,2, E.F.D. Croce1, C.G. Pimenta1, H.M.S. Bicalho1 and S.D.J. Pena
Brazil is a major producer and exporter of beef, with a herd of approximately 210 million animals. For the meat industry, a reliable animal traceback from its origin to the consumer market is paramount. Of all available identification systems, DNA is the only one that survives the slaughterhouse and reaches the dish of the consumer. DNA polymorphisms are .. Read More»

Impact of climatic factors on genetic diversity of Stipa breviflora populations in Inner Mongolia
Authors: Q. Zhang, J.M. Niu, S.B. Wu, A. Buyantuyev and J.J. Dong
Genetic diversity of Stipa breviflora populations in the Inner Mongolian grasslands of China and its possible correlation with climatic factors was examined using geographic information systems and random amplified polymorphism DNA analysis. A total of 308 bands were produced with 28 arbitrary decamer oligonucleotide. Three major findings were demonstrate.. Read More»

Cytogenetics of the darkling beetles Zophobas aff. confusus and Nyctobates gigas (Coleoptera, Tenebrionidae)
Authors: A.C. Lira-Neto, G.M. Silva, R.C. Moura and M.J. Souza
Males of Zophobas aff. confusus and Nyctobates gigas (Tenebrionidae) collected in the State of Pernambuco, Brazil, were studied through conventional staining, C-banding, silver nitrate impregnation (AgNO3), and the base specific fluorochromes CMA3 and DAPI. Z. aff. confusus was found to have 2n = 20 (9+Xyp) while N. gigas exhibited 2n = 18 (8+neoXY). Larg.. Read More»

Clinical retrospective analysis of cases with multiple primary malignant neoplasms
Authors: L.L. Xu and K.S. Gu
The etiological factors, clinical characteristics, diagnosis, treatment strategies, and prognosis of multiple primary malignant neoplasms (MPMNs) were investigated in order to improve its diagnosis and therapy. Clinical data of 170 patients with MPMN who were admitted to the Oncology Department of the First Affiliated Hospital of Anhui Medical University .. Read More»

Chromosomal evolution in the pallescens group (Hemiptera, Triatominae)
Authors: K.C.C Alevi, A. Ravazi, M.F. Franco-Bernardes, J.A. Rosa and M.T.V. Azeredo-Oliveira
Rhodnius colombiensis, in conjunction with R. pallescens and R. ecuadoriensis, forms the monophyletic pallescens group. Cytogenetic analyses of these closely related species would further our understanding of the taxonomy and evolution of this group. In this study, R. colombiensis was cytogenetically analyzed, and the results .. Read More»

Protein-protein interaction network analysis of osteoarthritis-related differentially expressed genes..
Authors: Y.C. Zhu1*, B.Y. Deng1*, L.G. Zhang1, P. Xu3, X.P. Du3, Q.G. Zhang1 and B. Yang2
The purpose of this study was to identify genes and pathways for osteoarthritis (OA) diagnosis and therapy. We downloaded the gene expression profile of OA from Gene Expression Omnibus (GEO) database including 10 early OA, 9 late OA, and 5 normal control samples. Next, we screened differentially expressed genes (DEGs) between early- and late-stage OA samp.. Read More»

Spermatogenesis and nucleolar behavior in Triatoma vandae and Triatoma williami (Hemiptera, Triatominae)
Authors: N.P. Pereira, K.C.C. Alevi, P.P. Mendon�§a and M.T.V. Azeredo-Oliveira
This study describes spermatogenesis in Triatoma vandae and the nucleolar behavior of T. vandae and Triatoma williami, with a cytotaxonomic focus. Analysis of mitotic and meiotic metaphases of T.vandae confirms the species karyotype. T. vandae presents some characteristics during meiosis that differentiate it from T. williami,.. Read More»

Fine mapping of a grain weight quantitative trait locus, qGW6, using near isogenic lines derived from Oryza rufipogon IRGC105491 and Oryza sativa cultivar MR219.
Authors: M.S. Ngu1, M.J. Thomson2, M.A.R. Bhuiyan1, C. Ho3 and R. Wickneswari1
Grain weight is a major component of rice grain yield and is controlled by quantitative trait loci. Previously, a rice grain weight quantitative trait locus (qGW6) was detected near marker RM587 on chromosome 6 in a backcross population (BC2F2) derived from a cross between Oryza rufipogon IRGC105491 and O. sativa cv. MR219. Using a BC2F5 population, qGW6 .. Read More»
