Identification and complete sequencing of novel human transcripts through the use of mouse orthologs and testis cDNA sequences

The correct identification of all human genes, and their derived transcripts, has not yet been achieved, and it remains one of the major aims of the worldwide genomics community. Computational programs suggest the existence of 30,000 to 40,000 human genes. However, definitive gene identification can only be achieved by experimental approaches. We used two distinct methodologies, one based on the alignment of mouse orthologous sequences to the human genome, and another based on the construction of a high-quality human testis cDNA library, in an attempt to identify new human transcripts within the human genome sequence. We generated 47 complete human transcript sequences, comprising 27 unannotated and 20 annotated sequences. Eight of these transcripts are variants of previously known genes. These transcripts were characterized according to size, number of exons, and chromosomal localization, and a search for protein domains was undertaken based on their putative open reading frames. In silico expression analysis suggests that some of these transcripts are expressed at low levels and in a restricted set of tissues.

Rendimento dos não-componentes da carcaça de cordeiros de diferentes genótipos

Non-carcass components percentages of lambs terminated in confinement, fed with diet containing 40:60 forage:concentrate ratio were influenced by lambs' breed (Morada Nova and 1/2 Somális Brasileira 1/2 Morada Nova), except for the liver, without difference between pure and crossbred animals, with average values of 2.29% and 0.35%, respectively. Crossbred lambs had higher percentages of skin (8.96%), head plus foot (10.68%), heart (0.88%), and kidney (0.93%) than purebred lambs (7.15%, 9.69%, 0.56% and 0.35%, respectively).

Effect of an acid diet allied to sonic toothbrushing on root dentin permeability: An in vitro study

This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the pulp tissue was removed. The root segments were connected to a hydraulic pressure apparatus to measure the permeability of root dentin after the following sequential steps, with 5 specimens in each: 1) phosphoric acid etching for 30 s (maximum permeability), 2) root planning to create new smear layer, 3) exposure to different acid substances for 5 min (orange, cola drink, vinegar, white wine, lemon juice), 4) toothbrushing with sonic toothbrush for 3 min, 5) toothbrushing with sonic toothbrush plus dentifrice for 3 min. Considering step I as 100%, the data were converted into percentage and each specimen was its own control. Data were analyzed statistically by Kruskal-Wallis and Dunn's post test at 5% significance level. All acidic substances increased dentin permeability significantly after scraping (p<0.05). Toothbrushing after exposure to acid substances decreased dentin permeability and the association with dentifrice accentuated the decrease (p<0.05), except for the specimens treated with cola drink. Thus, it may be concluded that all tested acid fruit juices increased dentin permeability, and toothbrushing with or without dentifrice can decrease root dentin permeability after dentin exposure to acid diet.

Homeobox gene expression profile indicates HOXA5 as a candidate prognostic marker in oral squamous cell carcinoma

The search for molecular markers to improve diagnosis, individualize treatment and predict behavior of tumors has been the focus of several studies. This study aimed to analyze homeobox gene expression profile in oral squamous cell carcinoma (OSCC) as well as to investigate whether some of these genes are relevant molecular markers of prognosis and/or tumor aggressiveness. Homeobox gene expression levels were assessed by microarrays and qRT-PCR in OSCC tissues and adjacent non-cancerous matched tissues (margin), as well as in OSCC cell lines. Analysis of microarray data revealed the expression of 147 homeobox genes, including one set of six at least 2-fold up-regulated, and another set of 34 at least 2-fold down-regulated homeobox genes in OSCC. After qRT-PCR assays, the three most up-regulated homeobox genes (HOXA5, HOXD10 and HOXD11) revealed higher and statistically significant expression levels in OSCC samples when compared to margins. Patients presenting lower expression of HOXA5 had poorer prognosis compared to those with higher expression (P=0.03). Additionally, the status of HOXA5, HOXD10 and HOXD11 expression levels in OSCC cell lines also showed a significant up-regulation when compared to normal oral keratinocytes. Results confirm the presence of three significantly upregulated (>4-fold) homeobox genes (HOXA5, HOXD10 and HOXD11) in OSCC that may play a significant role in the pathogenesis of these tumors. Moreover, since lower levels of HOXA5 predict poor prognosis, this gene may be a novel candidate for development of therapeutic strategies in OSCC.

Prevalência sorológica e molecular de Babesia bovis e Babesia bigemina em búfalos (Bubalus bubalis) na Ilha de Marajó, Pará

The aim of the study was to estimate the prevalence of Babesia bovis and Babesia bigemina in water buffaloes of the Marajó Island, State of Pará, Brazil. We used an indirectenzyme- linked immunosorbent assay (iELISA), with total antigen containing proteins outer surface, and polymerase chain reaction (qPCR), involving the use of SYBR Green based on amplification of a small fragment of the cytochrome b gene. The prevalence of positive animals in iELISA to B. bovis B. bigemina and mixed infection was 24.87% (199/800), 20.75% (166/800) and 18.75% (150/800), respectively. Using the PCR, the presence of B. bovis wasdetected in 15% (18/199) and B. bigemina in 16% (19/199) of animals, and of these, 58% (11/19) presented co-infected by the two agents. The results show a low prevalence of antibodies anti-B. bovis and anti-B. bigemina in water buffaloes from Marajó Island. However, it was observed that the agents of bovine babesiosis circulate in buffaloes, and these may act as reservoirs.
