Contaminação do solo com antraceno e creosoto e o crescimento vegetal e a colonização micorrízica pelo Glomus etunicatum

A contaminação do solo por compostos orgânicos, especialmente os hidrocarbonetos aromáticos policíclicos (HAPs) de petróleo, é um problema crescente e que traz graves conseqüências ambientais. Para avaliar os impactos causados por esses compostos, torna-se necessário conhecer seus efeitos sobre as plantas e a microbiota rizosférica associada. No presente estudo avaliaram-se os efeitos de antraceno e creosoto no crescimento e na colonização micorrízica de Brachiaria brizantha e Pueraria phaseoloides. Antraceno e creosoto foram aplicados a um solo infestado com o fungo micorrízico Glomus etunicatum, sendo: antraceno nas concentrações de 0; 0,25; 0,5; 0,75 e 1 g kg-1 solo; e creosoto nas concentrações de 0; 0,5; 1; 2 e 3 g kg-1 solo. O solo com os tratamentos foi colocado em tubetes (290 cm³) e semeado com as plantas-teste, as quais foram cultivadas por seis semanas. Verificou-se que o antraceno não afetou o crescimento da puerária e teve pequeno estímulo no crescimento da braquiária na dose mais baixa, enquanto o creosoto reduziu o crescimento da braquiária e não teve efeito na puerária. Entretanto, ambos os contaminantes inibiram a colonização micorrízica da puerária, atingindo redução de cerca de 90 % em relação ao controle. Em concentrações bem inferiores às encontradas em solos contaminados, a colonização micorrízica foi inibida em 50 %, ficando evidente o potencial de impacto desses poluentes na relação planta-fungo micorrízico. Na braquiária não foi encontrada colonização micorrízica. Fica evidenciada a resposta diferenciada das duas espécies estudadas aos contaminantes e o acentuado efeito negativo destes sobre a colonização micorrízica. A puerária, por ter se mostrado insensível aos HAPs, nas concentrações estudadas, apresenta potencial para aplicação na fitorremediação de áreas impactadas por esses contaminantes.

Human natural Treg microRNA signature: role of microRNA-31 and microRNA-21 in FOXP3 expression.

Treg are the main mediators of dominant tolerance. Their mechanisms of action and applications are subjects of considerable debate currently. However, a human microRNA (miR) Treg signature has not been described yet. We investigated human natural Treg and identified a signature composed of five miR (21, 31, 125a, 181c and 374). Among those, two were considerably under-expressed (miR-31 and miR-125a). We identified a functional target sequence for miR-31 in the 3' untranslated region (3' UTR) of FOXP3 mRNA. Using lentiviral transduction of fresh cord blood T cells, we demonstrated that miR-31 and miR-21 had an effect on FOXP3 expression levels. We showed that miR-31 negatively regulates FOXP3 expression by binding directly to its potential target site in the 3' UTR of FOXP3 mRNA. We next demonstrated that miR-21 acted as a positive, though indirect, regulator of FOXP3 expression. Transduction of the remaining three miR had no direct effect on FOXP3 expression or on the phenotype and will remain the subject of future investigations. In conclusion, not only have we identified and validated a miR signature for human natural Treg, but also unveiled some of the mechanisms by which this signature was related to the control of FOXP3 expression in these cells.
