Differential expression of the tumor suppressor A-kinase anchor protein 12 in human diffuse and pilocytic astrocytomas is regulated by promoter methy…

2013

The scaffold protein A-kinase anchor protein 12 (AKAP12) exerts tumor suppressor activity and is downregulated in several tumor entities. We characterized AKAP12 expression and regulation in astrocytomas, including pilocytic and diffusely infiltrating astrocytomas. We examined 194 human gliomas and 23 normal brain white matter samples by immunohistochemistry or immunoblotting for AKAP12 expression. We further performed quantitative methylation analysis of the AKAP12 promoter by MassARRAY® of normal brain, World Health Organization (WHO) grade I to IV astrocytomas, and glioma cell lines. Our results show that AKAP12 is expressed in a perivascular distribution in normal CNS, strongly upregula…

CD133 expression is associated with small round blue cell tumour morphology in human central nervous system neoplasms

2011

Schittenhelm J, Simon P, Harter P N, Zachskorn C, Schlaszus H, Rottger F, Winkels M, Weller M, Meyermann R & Mittelbronn M (2011) Histopathology58, 739–749 CD133 expression is associated with small round blue cell tumour morphology in human central nervous system neoplasms Aims:  CD133 is considered to be a marker for brain tumour-initiating cells. However, most data on CD133 are derived from animal or in-vitro studies. The aim of this study was to characterize CD133 expression, and the distribution and morphological features of CD133+ cells, in primary and secondary human central nervous system (CNS) neoplasms. Methods and results:  Tumours were analysed by real-time reverse transcription …
