APRIL, a new ligand of the tumor necrosis factor family, stimulates tumor cell growth.

Members of the tumor necrosis factor (TNF) family induce pleiotropic biological responses, including cell growth, differentiation, and even death. Here we describe a novel member of the TNF family designated APRIL (for a proliferation-inducing ligand). Although transcripts of APRIL are of low abundance in normal tissues, high levels of mRNA are detected in transformed cell lines, and in human cancers of colon, thyroid, and lymphoid tissues in vivo. The addition of recombinant APRIL to various tumor cells stimulates their proliferation. Moreover, APRIL-transfected NIH-3T3 cells show an increased rate of tumor growth in nude mice compared with the parental cell line. These findings suggest that APRIL may be implicated in the regulation of tumor cell growth.

Energy expenditure during walking and running in obese and nonobese prepubertal children.

We measured body composition and energy expenditure during walking and running on a treadmill in 40 prepubertal children: 23 obese children (9.3 +/- 1.1 years of age; 46 +/- 10 kg (mean +/- SD)) and 17 nonobese matched control children (9.2 +/- 0.6 years of age; 30 +/- 5 kg). Energy expenditure was assessed by indirect calorimetry with a standard open-circuit method. At the same speed of exercise, the energy expenditure was significantly (p < 0.01) greater in obese than in control children, in both boys and girls. Expressed per kilogram of body weight or per kilogram of fat-free mass, the energy expenditure was comparable in the two groups. Obese children had a significantly (p < 0.01) larger pulmonary ventilatory response to exercise than did control children. Heart rate was comparable in boys and girls combined but significantly higher (p < 0.05) in obese subjects, if boys and girls were analyzed separately. These data indicate that walking and running are energetically more expensive for obese children than for children of normal body weight. The knowledge of these energy costs could be useful in devising a physical activity program to be used in the treatment of obese children.

Fatores associados à hipertensão arterial e níveis pressóricos encontrados entre adolescentes trabalhadores

O objetivo deste trabalho foi identificar fatores associados (FA) à hipertensão arterial e verificar níveis pressóricos de adolescentes trabalhadores. Foram entrevistados 193 adolescentes, sendo 135 homens e 58 mulheres, entre 16 e 18 anos. Após cinco minutos sentados, mediu-se a circunferência braquial e determinou-se a pressão arterial (PA), usando manguito de largura correta (MLC) e padrão (MLP). Os valores obtidos foram relacionados aos FA encontrados. As médias pressóricas, considerando todos os adolescentes, foram 105,2/60,9 mmHg (MLC) e 101,0/57,9 (MLP-p<0,05). Dentre os FA encontrados, apenas a cor e a ingestão de bebidas alcoólicas foram associadas ao aumento da PA. O uso do MLC permitiu a detecção de maior número de hipertensos e limítrofes que o uso do MLP. Todos apresentaram FA. Pode-se concluir que há vários FA com hipertensão arterial nessa população, alguns deles já causando elevação da PA. Estudos como este deveriam ser realizados freqüentemente entre adolescentes, pois seus níveis pressóricos podem pre-dizer hipertensão na fase adulta.

The transcriptome of the arbuscular mycorrhizal fungus Glomus intraradices (DAOM 197198) reveals functional tradeoffs in an obligate symbiont.

? The arbuscular mycorrhizal symbiosis is arguably the most ecologically important eukaryotic symbiosis, yet it is poorly understood at the molecular level. To provide novel insights into the molecular basis of symbiosis-associated traits, we report the first genome-wide analysis of the transcriptome from Glomus intraradices DAOM 197198. ? We generated a set of 25,906 nonredundant virtual transcripts (NRVTs) transcribed in germinated spores, extraradical mycelium and symbiotic roots using Sanger and 454 sequencing. NRVTs were used to construct an oligoarray for investigating gene expression. ? We identified transcripts coding for the meiotic recombination machinery, as well as meiosis-specific proteins, suggesting that the lack of a known sexual cycle in G. intraradices is not a result of major deletions of genes essential for sexual reproduction and meiosis. Induced expression of genes encoding membrane transporters and small secreted proteins in intraradical mycelium, together with the lack of expression of hydrolytic enzymes acting on plant cell wall polysaccharides, are all features of G. intraradices that are shared with ectomycorrhizal symbionts and obligate biotrophic pathogens. ? Our results illuminate the genetic basis of symbiosis-related traits of the most ancient lineage of plant biotrophs, advancing future research on these agriculturally and ecologically important symbionts.
