Pkc1 acts through Zds1 and Gic1 to suppress growth and cell polarity defects of a yeast eIF5A mutant

eIF5A is a highly conserved putative eukaryotic translation initiation factor that has been implicated in translation initiation, nucleocytoplasmic transport, mRNA decay, and cell proliferation, but with no precise function assigned so far. We have previously shown that high-copy PKCI suppresses the phenotype of tif51A-1, a temperature-sensitive mutant of eIF5A in S. cerevisiae. Here, in an attempt to further understand how Pkc1 functionally interacts with eIF-5A, it was determined that PKCI suppression of tif51A-1 is independent of the cell integrity MAP kinase cascade. Furthermore, two new suppressor genes, ZDS1 and GIC1, were identified. We demonstrated that ZDS1 and ZDS2 are necessary for PKC1, but not for GIC1 suppression. Moreover, high-copy GIC1 also suppresses the growth defect of a PKCI mutant (stt1), suggesting the existence of a Pkc1-Zds1-Gic1 pathway. Consistent with the function of Gic1 in actin organization, the tif51A-1 strain shows an actin polarity defect that is partially recovered by overexpression of Pkc1 and Zds1 as well as Gic1. Additionally, PCL1 and BNI1, important regulators of yeast cell polarity, also suppress tif51A-1 temperature sensitiviiy Taken together, these data strongly Support the correlated involvement of Pkc1 and eIF5A in establishing actin polarity, which is essential for bud formation and G1/S transition in S. cerevisiae.

Administrative rationality and coping strategies in shift work

Shift work (SW) can affect worker health and productivity. Working at night, workers often accumulate fatigue and are less productive. In Brazil, laws have been drafted aiming to reduce night work and rotating shift hours. In order to slash costs, companies have been looking for new arrangements to improve productivity under these conditions. The purpose of this study was to examine management changes and their outcomes in a large glass factory located in an industrial region of Brazil. The results show that the management, seeking equal productivity among shifts, focused its efforts mainly on distributing employee expertise. The arrangement resulted in 12 different groups that combine to serve three fixed shifts. A same shift can be served by more than one group, and the members of a same group share days off on different days. There was no statistically significant productivity difference among the three shifts. The on-site examination showed that part of the production was held by the workers and transferred to the next shift in order for them to be able to meet the management's performance rate requirements. The finding shows how a Brazilian cultural trait (resistance without conflict) is used to drive coping in SW.

The Approach To The Administrative Mapping In Knowledge Management For Portugal Libraries

In the study of theoretical trends in Administration, the management of information follows the development of theories of Administration; constant-adaptations are suffered. Information Science as Museums, Archives and Libraries, understands and concerns itself with the changes wrought in these endeavour of the knowledge society as new forms of communication and integration. They interact in ways such as to maximize access to information and facilitate improvement on their structural environment. The research aims at identifies the requirements and specifications of an information system for knowledge management in the public's library enviromnent and proposes to achieve a pre-defined structure for the implementation of administration management. The research is conducted with public's library of the metropolian region of the North's Portugal. In the improvement of systems theoretical administrative trends become management decisions and result in the ultimate success of the organization.

MicroRNA-100 Acts as a Tumor Suppressor in Human Bladder Carcinoma 5637 Cells

Bladder carcinoma is one of the most common tumors in the world and, despite the therapy currently available, most of the patients relapse. Better understanding of the factors involved in disease pathogenesis would provide insights for the development of more effective strategies in treatment. Recently, differential miRNA expression profiles in bladder urothelial carcinomas identified miR-100 down-regulation and miR-708 up-regulation among the most common alterations, although the possible influence of these miRNAs in the control of basic mechanisms in bladder tumors has not been addressed. In this context, the present study aimed to evaluate the in vitro effects of miR-100 forced expression and miR-708 inhibition in the bladder carcinoma cell line 5637. Our results showed that overexpression of miR-100 significantly inhibited growth when compared to controls at both times tested (72 and 96 hours, p<0.01) with a maximum effect at 72 hours reducing proliferation in 29.6 %. Conversely, no effects on cell growth were observed after inhibition of miR-708. MiR-100 also reduced colony formation capacity of 5637 cells by 24.4%. No alterations in cell cycle progression or apoptosis induction were observed. The effects of miR-100 on growth and clonogenicity capacity in 5637 cells evince a possible role of this miRNA in bladder carcinoma pathogenesis. Further studies are necessary to corroborate our findings and examine the potential use of this microRNA in future therapeutic interventions.

TNF-alpha acts in the hypothalamus inhibiting food intake and increasing the respiratory quotient - Effects on leptin and insulin signaling pathways

Acting in the hypothalamus, tumor necrosis factor-alpha (TNF-alpha) produces a potent anorexigenic effect. However, the molecular mechanisms involved in this phenomenon are poorly characterized. In this study, we investigate the capacity of TNF-alpha to activate signal transduction in the hypothalamus through elements of the pathways employed by the anorexigenic hormones insulin and leptin. High dose TNF-a promotes a reduction of 25% in 12 h food intake, which is an inhibitory effect that is marginally inferior to that produced by insulin and leptin. In addition, high dose TNF-a increases body temperature and respiratory quotient, effects not reproduced by insulin or leptin. TNF-alpha, predominantly at the high dose, is also capable of activating canonical pro-inflammatory signal transduction in the hypothalamus, inducing JNK, p38, and NF kappa B, which results in the transcription of early responsive genes and expression of proteins of the SOCS family. Also, TNF-a activates signal transduction through JAK-2 and STAT-3, but does not activate signal transduction. through early and intermediary elements of the insulin/leptin signaling pathways such as IRS-2, Akt, ERK and FOXO1. When co-injected with insulin or leptin, TNF-a, at both high and low doses, partially impairs signal transduction through IRS-2, Akt, ERK and FOXO1 but not through JAK-2 and STAT-3. This effect is accompanied by the partial inhibition of the anorexigenic effects of insulin and leptin, when the low, but not the high dose of TNF-alpha is employed. In conclusion, TNF-alpha, on a dose-dependent way, modulates insulin and leptin signaling and action in the hypothalamus. (c) Published by Elsevier B.V.
