Essential amino acid usage and evolutionary nutrigenomics of eukaryotes - insights into the differential usage of amino acids in protein domains and extra-domains
Authors: L. Santana-Santos, F. Prosdocimi and J.M. Ortega
Nutrigenomics studies the effects of nutrients on the genome, transcriptome and proteome of organisms, and here an evolutionary standpoint on this new discipline is presented. It is well known that metazoan organisms are unable to synthesize all amino acids necessary to produce their proteins and that these essential amino aci.. Read More»

Anthranilate synthase subunit organization in Chromobacterium violaceum
Authors: C.A. Carminatti, I.L. Oliveira, D.O.S. Recouvreux,R.V. Ant�´nio and L.M. Porto
Tryptophan is an aromatic amino acid used for protein synthesis and cellular growth. Chromobacterium violaceum ATCC 12472 uses two tryptophan molecules to synthesize violacein, a secondary metabolite of pharmacological interest. The genome analysis of this bacterium revealed that the genes trpA-F and pabA-B encode the enzymes .. Read More»

Epstein-Barr virus DNA associated with gastric adenocarcinoma and adjacent non-cancerous mucosa in patients from Manaus, Brazil
Authors: P.F. de Aquino P.C. Carvalho J.S. da Gama Fischer A.Q.L. de Souza J.S. Viana S.R.S. Chalub A.D.L. de Souza M.G.C. Carvalho
Gastric cancer is one of most frequent causes of death in Brazil. The city of Manaus has one of the highest incidences of this disease in Brazil. The Epstein-Barr virus (EBV) is a ubiquitous herpesvirus that is classified as a group 1 carcinogen by the International Agency for Research on Cancer. We obtained biopsies from 6 control subjects and 10 patient.. Read More»

Phylogeny and systematics of Indian Polygonum sensu lato in the subfamily Polygonoideae based on ITS sequences of nuclear ribosomal DNA
Authors: R.K. Choudhary S.-H. Park J. Lee
The nuclear ribosomal DNA internal transcribed spacer (ITS) sequences from 44 Indian Polygonum taxa were examined to investigate relationships among various sections proposed by earlier researchers. The maximum parsimony trees obtained from analysis of the ITS sequences suggested eight major groups of the Indian Polygonum spp. The relationships among diff.. Read More»

Population genetic structure of the blue-fronted Amazon (Amazona aestiva, Psittacidae: Aves) based on nuclear microsatellite loci: implications for conservation
Authors: K.C.E. Leite, G.H.F. Seixas, I. Berkunsky , R.G. Collevattiand R. Caparroz
The blue-fronted Amazon (Amazona aestiva) is a widely distributed Neotropical parrot and one of the most captured parrots in nature to supply the illegal trade of wild animals. The objectives of the present study were to analyze the genetic structure of A. aestiva to identify management units and support conservation planning .. Read More»

Influence of the halothane gene (HAL) on pork quality in two commercial crossbreeds
Authors: A.C.P. Silveira, P.F.A. Freitas, A.S.M. Cesar, R.C. Antunes, E.C. Guimar�£es, D.F.A. Batista and L.C. Torido
We evaluated the effect of the halothane (HAL) gene on the quality of pork in domestic pigs. Half-carcasses from two different commercial pig (Sus domestica) crossbreeds were analyzed, 46 of which were homozygous dominant (HALNN) and 69 of which were heterozygous (HALNn) for the halothane gene. The measures included backfat th.. Read More»

Fluorescence in situ hybridization analysis with subtelomere specific probes (12pter-15qter) showed no differences in deletion patterns between normotensive and essential hypertension
Authors: S.T. Onrat and A.G. Tomat�±r
Telomere biology is intimately linked to the genetic/environmental etiology of cardiovascular and metabolic diseases and telomere shortening is emerging as an important biomarker disease. The relationship between subtelomeric deletions and genetic hypertension was examined. Fluorescence in situ hybridization was used to direct.. Read More»

Heterogeneous evolution of Ty3-gypsy retroelements among bamboo species
Authors: M.M. An, C. Guo, P.P. Lin and M.B. Zhou
Ty3-gypsy long-terminal repeat retroelements are ubiquitously found in many plant genomes. This study reports the occurrence of heterogeneous Ty3-gypsy retroelements in four representative bamboo species: Phyllostachys heterocycla (Carr.) Mitford cv. pubescens, P. heterocycla (Carr.) Mitford cv. heterocycla, Dendrocalamopsis oldhami, and Pleioblastus fort.. Read More»

Development of two novel specific SCAR markers by cloning improved RAPD fragments from the medicinal mushroom Ganoderma lucidium (Leysser: Fr) Karst
Authors: M.A. Khan, J.L. Cheng, Z.Q. Mei, C.L. Wei and J.J. Fu
Development of sequence-characterized amplified region (SCAR) markers from random-amplified polymorphic DNA (RAPD) fragments is a valuable molecular approach for the genetic identification of different species. By using SCAR markers, molecular analysis is reduced to a simple polymerase chain reaction (PCR) analysis using primers designed from the amplicon.. Read More»
