Paragraph: CD13/Aminopeptidase N (CD13) is known to play an important role in tumour cell invasion. We examined whether basic fibroblast growth factor (bFGF) is involved in the regulation of CD13 expression in human melanoma cells. 1F6 human melanoma cells were stably transfected with constructs encoding either the 18 kDa (18kD) or all (ALL) bFGF isoform proteins. We observed highly increased CD13 mRNA and protein expression in the 1F6 clones regardless of the overexpression of either the 18kD or all isoform proteins. Neutral aminopeptidase activity was increased five-fold and could be inhibited by bestatin and the CD13-neutralising antibody WM15. The enhanced invasion through Matrigel, but not migration in a wound assay, was efficiently abrogated by both bestatin and WM15. Upregulation of CD13 expression was the result of increased epithelial and myeloid promoter activity up to 4.5fold in 1F6-18kD and 1F6-ALL clones. Interestingly, in a panel of human melanoma cell lines, a significant correlation (r 2 ¼ 0.883, Po0.05) between bFGF and CD13 mRNA and protein expression was detected. High bFGF and CD13 expression were clearly related with an aggressive phenotype. Taken together, our data indicate that high bFGF expression upregulates CD13 expression in human melanoma cells by activating both the myeloid and the epithelial CD13 promoter. In addition, we show that high bFGF and CD13 expression results in enhanced invasive capacity and metastatic behaviour of human melanoma cells.

Paragraph: Here we describe a new technical solution for optimization of Pichia pastoris shake flask cultures with the example of production of stable human type II collagen. Production of recombinant proteins in P. pastoris is usually performed by controlling gene expression with the strong AOX1 promoter, which is induced by addition of methanol. Optimization of processes using the AOX1 promoter in P. pastoris is generally done in bioreactors by fed-batch fermentation with a controlled continuous addition of methanol for avoiding methanol toxification and carbon/energy starvation. The development of feeding protocols and the study of AOX1-controlled recombinant protein production have been largely made in shake flasks, although shake flasks have very limited possibilities for measurement and control. Results: By applying on-line pO 2 monitoring we demonstrate that the widely used pulse feeding of methanol results in long phases of methanol exhaustion and consequently low expression of AOX1 controlled genes. Furthermore, we provide a solution to apply the fed-batch strategy in shake flasks. The presented solution applies a wireless feeding unit which can be flexibly positioned and allows the use of computer-controlled feeding profiles. By using the human collagen II as an example we show that a quasi-continuous feeding profile, being the simplest way of a fed-batch fermentation, results in a higher production level of human collagen II. Moreover, the product has a higher proteolytic stability compared to control cultures due to the increased expression of human collagen prolyl 4hydroxylase as monitored by mRNA and protein levels. The recommended standard protocol for methanol addition in shake flasks using pulse feeding is nonoptimal and leads to repeated long phases of methanol starvation. The problem can be solved by applying the fed-batch technology. The presented wireless feeding unit, together with an on-line monitoring system offers a flexible, simple, and low-cost solution for initial optimization of the production in shake flasks which can be performed in parallel. By this way the fed-batch strategy can be applied from the early screening steps also in laboratories which do not have access to highcost and complicated bioreactor systems.

Interferon (IFN) administration is the main therapy for HCV-infected individuals, but still a fraction of them are not completely responsive to the treatment. Several HCV proteins such as core, E2, and NS5A proteins have been demonstrated to attenuate IFN responses through different mechanisms. In the present study, we examined whether HCV NS4B, a membrane-bound protein whose functions are mostly unknown, exerted any effects on IFN-induced antiviral responses. From the reporter assay, we showed that NS4B significantly suppressed IFN-induced activation of IFNstimulated responsive element (ISRE) promoter activity. We further examined the ability of HCV NS4B to confer IFN resistance on VSV, an originally IFN-sensitive virus, by a trans-rescue assay. The viral titer was low when cells were treated with IFN-a, which, however, was significantly increased by HCV NS4B. We also examined the effects of HCV NS4B on the transcription of interferon-stimulated genes (ISGs) by qRT-PCR and found that the IFN-induced expression of ISG15, ISG54, ISG56, and OAS2-p69 was significantly downregulated by NS4B. The results were confirmed by chromatin immunoprecipitation (ChIP) assay . The levels and the activation status of the interferon-stimulated gene factor 3 (ISGF3), known to regulate the IFN pathway, were also noticeably reduced by NS4B. Taken together, these results strongly suggest that, in addition to the above mentioned HCV proteins, HCV NS4B may also play a role in IFN antagonism.
