2. Correlation of expression of hypoxia-related proteins with prognosis in oral squamous cell carcinoma patients

Author

Eckert, A., Kappler, M., Schubert, J., and Taubert, H.

Abstract

Abstract: Introduction: Hypoxia plays a major role in tumor progression, therapy resistance and for prognosis of oral squamous cell carcinoma (OSCC). The crucial step as a response to hypoxia is the activation and stabilization of the alpha subunit of hypoxia inducible factor 1 (HIF-1α). HIF-1: HIF-1 regulates the expression of different genes to adapt the tumor cells to reduced oxygenation. The HIF-1 system is intrinsic regulated by von Hippel–Lindau protein (pVHL). Main downstream proteins are the glucose transporter 1 (GLUT-1), carbonic anhydrase IX (CAIX), and vascular endothelial growth factor (VEGF). For therapeutical stratification in OSCC, it is important to understand the mechanism caused by hypoxic stress and to comprehend the resulting adaptive process in cancer cells. Therefore, an overview of HIF-1α-depending protein expression, focussed on the expression of GLUT-1, CAIX, and VEGF and their prognostic significance in OSCC is given. Conclusion: Several unique roles of hypoxic pathway in the context of tumor progression are described in this review. As a consequence, a marker panel is proposed to allow a more individualized prognosis in OSCC patients. This marker panel should include beside HIF-1α, pVHL, and GLUT-1.

3. Detection and Specific Targeting of Hypoxic Regions within Solid Tumors: Current Preclinical and Clinical Strategies

Author

Bache, M., Kappler, M., Said, H., Staab, A., and Vordermark, D.

Abstract

Poor oxygenation of solid tumors is a major indicator of adverse prognosis after standard treatment, e. g. radiotherapy. This observation founded on intratumoral pO2 electrode measurements has been supported more recently by studies of injected hypoxia markers (pimonidazole, EF5) or hypoxia-related proteins (hypoxia-inducible factor-1, carbonic anhydrase IX) detected immunohistochemically. Alternative approaches include imaging of tumor hypoxia by nuclear medicine studies and the measurement of hypoxia-related proteins (osteopontin) in patient plasma. Low oxygen levels as found in tumors are rarely observed in normal tissues. The presence of hypoxic tumor cells is therefore regarded not only as an adverse prognostic factor but as an opportunity for tumor-specific treatment. Classic approaches to normalize tumor oxygenation involve the breathing of modified gas mixtures and pharmacologic modification of blood flow as in the “accelerated radiotherapy, carbogen, nicotinamide” (ARCON) scheme. Specific killing of hypoxic tumor cells can potentially be achieved by hypoxia-selective cytotoxins (model substance tirapazamine), which has shown promise in head and neck cancer. Direct targeting of hypoxia-related molecules such as hypoxia-inducible factor-1, the central regulator of the hypoxic response in tumor cells, is an attractive approach currently tested in preclinical models. For clinical applications, the appropriate combination of hypoxia detection for patient selection with a hypoxia-specific treatment is essential. A therapeutic benefit has been suggested for the selection of patients by plasma osteopontin level and treatment with the hypoxic radiosensitizer nimorazole in addition to radiotherapy, for selection by F-misonidazole positron-emmission tomography (PET) and treatment with tirapazamine in addition to chemoradiation and for selection by pimonidazole immunohistochemistry and ARCON treatment, all in head and neck cancer.

4. Experiments on the flow past long circular cylinders in a shear flow

Author

Kappler, M., Rodi, W., Szepessy, S., and Badran, O.

Abstract

Abstract This paper describes an experimental investigation of the flow past circular cylinders, with the mean flow perpendicular to the cylinder axis, at conditions that yield a strong three-dimensional behaviour. The experiments were carried out in the subcritical regime. Long cylinders with end plates were subjected to shear flow with a linear velocity profile in the spanwise direction generated by means of a curved gauze. It was concluded that spanwise cellular structures of vortex shedding emerged in the wake, more clearly for some boundary conditions than others. These structures are characterised by a portion of spanwise length, a cell, having constant shedding frequency over a time average, which implies that there were no vortex dislocations inside that cell during that time. These features were studied using flow visualisation and hot-film anemometry. Spectra of the local shedding frequency are shown, revealing the effect of the shear parameter ß (=0.02 and 0.04) and aspect ratio L/D (=20.6 and 8) on the stability and geometry of the cells at several Reynolds numbers in the range of 3.13×103=Rem=1.25×104.
