Abstract

Verificou-se o potencial de parasitismo de Campoletis flavicincta (Ashmead) (Hymenoptera: Ichneumonide) sobre lagartas de Spodoptera frugiperda (Smith) de diferentes idades e o consumo foliar de lagartas parasitadas, em relacao a nao parasitadas. Quando foram oferecidas ao parasitoide lagartas de 3-d o numero medio de lagartas parasitadas foi de 232/femea, numero semelhante ao que foi obtido com lagartas de 2-d (182,0 lagartas/femea). Com lagartas de 4-5-d, o numero medio de parasitismo foi, respectivamente, 80,7 e 71,0 individuos parasitados/femea. Lagarta sadias, durante todo o seu periodo de vida, consumiram, em media, 209,3 cm3 de area foliar, enquanto que as lagartas parasitadas consumiram apenas 14,5 cm3 (6,9% do consumo de uma lagarta sadia).

Abstract

Estudou-se em laboratorio, aspectos biologicos do parasitoide Campoletis flavicincta (Ashmead) utilizando como hospedeiro larvas de Spodoptera frugiperda (Smith). Dez casais recem-nascidos de C. flavicincta foram individualizados no interior de vidros transparentes, (9,5 cm de diametro x 22 cm de altura) cobertos com um tecido fino, com solucao acucarada enriquecida com acido ascorbico. Sob condicoes de temperatura de 25 +/_ 2oC, umidade relativa de 70 +/- 10% e fotofase de 12 horas, cada casal recebeu diariamente cerca de 50 lagartas de tres dias de idade da especie S. frugiperda. Apos cada periodo de parasitismo as larvas foram individualizadas em copos plasticos contendo dieta artificial. O ciclo biologico total do parasitoide foi de 19,3 dias, sendo de 12,1 dias o periodo de ovo-larva e 7,2 dias o periodo de pupa. O peso medio da pupas foi de 8,3mg. A longevidade dos adultos foi em media 29,3 dias para os machos e 23,3 para as femeas. O periodo de parasitismo foi de 25 dias, com uma media de 18 lagartas parasitadas por dia. Houve predominancia de machos, com uma razao sexual de 0,15.

25. Twin hydroxymethyluracil-A base pair steps define the binding site for the DNA-binding protein TF1.

Author

Grove, A, Figueiredo, M L, Galeone, A, Mayol, L, and Geiduschek, E P

Abstract

The DNA-bending protein TF1 is the Bacillus subtilis bacteriophage SPO1-encoded homolog of the bacterial HU proteins and the Escherichia coli integration host factor. We recently proposed that TF1, which binds with high affinity (Kd was approximately 3 nM) to preferred sites within the hydroxymethyluracil (hmU)-containing phage genome, identifies its binding sites based on sequence-dependent DNA flexibility. Here, we show that two hmU-A base pair steps coinciding with two previously proposed sites of DNA distortion are critical for complex formation. The affinity of TF1 is reduced 10-fold when both of these hmU-A base pair steps are replaced with A-hmU, G-C, or C-G steps; only modest changes in affinity result when substitutions are made at other base pairs of the TF1 binding site. Replacement of all hmU residues with thymine decreases the affinity of TF1 greatly; remarkably, the high affinity is restored when the two hmU-A base pair steps corresponding to previously suggested sites of distortion are reintroduced into otherwise T-containing DNA. T-DNA constructs with 3-base bulges spaced apart by 9 base pairs of duplex also generate nM affinity of TF1. We suggest that twin hmU-A base pair steps located at the proposed sites of distortion are key to target site selection by TF1 and that recognition is based largely, if not entirely, on sequence-dependent DNA flexibility.

Abstract

Elevation in the intracellular Ca(2+) concentration stimulates glucagon secretion from pancreatic α-cells. The Transient Receptor Potential Melastatin 4 channel (TRPM4) is critical for Ca(2+) signaling. However, its role in glucagon secreting α-cells has not been investigated. We identified TRPM4 gene expression and protein in the αTC1-6 cell line using RT-PCR and immunocytochemistry. Furthermore, we performed a detailed biophysical characterization of the channel using the patch-clamp technique to confirm that currents typical for TRPM4 were present in αTC1-6 cells. To investigate TRPM4 function, we generated a stable knockdown clone using shRNA and a lentiviral vector. Inhibition of TRPM4 significantly reduced the responses to different agonists during Ca(2+) imaging analysis with Fura-2AM. The reduction in the magnitude of Ca(2+) signals resulted in decreased glucagon secretion. These results suggested that depolarization by TRPM4 may play an important role in controlling glucagon secretion from α-cells and perhaps glucose homeostasis., (Copyright © 2011 Elsevier Ireland Ltd.

29. Expression of cell-cycle regulator CDK2-associating protein 1 (p12CDK2AP1) in transgenic mice induces testicular and ovarian atrophy in vivo.

Abstract

The novel cell-cycle regulator p12(CDK2AP1) (p12) gene encodes a cyclin-dependent kinase 2 (CDK2) partner that participates in cell-cycle regulation, apoptosis, and proliferation. CDK2 has been implicated in maintenance of gonadal homeostasis, as knockout mice display reproductive abnormalities. To investigate the role of p12 in homeostasis of gonadal tissues in vivo, we generated a transgenic mouse model driven by the human keratin 14 promoter, reported to target transgene expression to gonadal tissues and also stratified epithelia. Overexpression of the transgene was associated with a gonadal atrophy phenotype in mice of both sexes, yet fertility was not impaired. Histological evaluation of testes showed seminiferous tubule degeneration and decreased tubule diameter. Female transgenic mice had small ovaries, with a higher number of atretic follicles/mm(2) as compared to control nontransgenic mice. Also observed was increased germ cell apoptosis in both sexes (TUNEL). These results suggest that overexpression of p12 leads to testicular and ovarian abnormalities, a phenotype closely related to that of cdk2-/- mice. In combination, these observations suggest that the p12/CDK2 signaling pathways are carefully orchestrated to maintain proper gonadal tissue homeostasis. We suggest that the mechanisms of this regulation may be through p12-mediated altered expression of gonadal-specific genes and apoptotic pathways.

Abstract

The case of a 66-year-old woman with several episodes of hemorrhage by esophageal varices and ascites due to portal hypertension is presented. Despite 4 sessions of endoscopic sclerotherapy bleeding recurred. A transjugular intrahepatic portosystemic shunt was performed. In the 10 months following the intervention, there was no further hemorrhage, the ascites disappeared and the shunt is open.
