Aqp 9 and Brain Tumour Stem Cells
Several studies have implicated the aquaporins (aqp) 1, 4, and 9 in the pathogenesis of malignant brain tumours, suggesting that they contribute to motility, invasiveness, and oedema formation and facilitate metabolism in tumour cells under hypoxic conditions. We have studied the expression of aqp1, 4, and 9 in biopsies from glioblastomas, isolated tumour stem cells grown in a tumoursphere assa...
متن کاملmobile phone use and brain tumour: an age-period-cohort analysis of brain tumour rates in the nordic population
background : the association of the mobile phone use and risk of brain tumor remains controversial among radiationepidemiologists. methods : we hypothesized if an association between brain tumor and mobile phone use exists, this association will be manifested as a cohort effect (as a proxy of association between mobile phone use and brain tumor) in the incidence rates of brain tumor during the ...
متن کاملBrain tumour stem cells: the undercurrents of human brain cancer and their relationship to neural stem cells.
Conceptual and technical advances in neural stem cell biology are being applied to the study of human brain tumours. These studies suggest that human brain tumours are organized as a hierarchy and are maintained by a small number of tumour cells that have stem cell properties. Most of the bulk population of human brain tumours comprise cells that have lost the ability to initiate and maintain t...
متن کاملBrain tumour and pregnancy.
Some 35 years ago, in Brouwer's clinic, OQjenick, deVet, and one of the authors (J.J.M.) observed a female patient with intermittent disturbances of the visual field due to compression of the optic chiasm by a meningioma. Her history indicated that the visual difficulties occurred toward the end of each of her frequent pregnancies-she had seven-and disappeared again after each delivery. They be...
متن کاملBrain Tumour Imaging
There is now a plethora of different imaging techniques used for diagnosing and treating brain tumours. Different contrast agents in magnetic resonance imaging – coupled with amino acid tracers used in positron emission tomography – are the new weapons in radiologists’ armoury which allow them to target and measure tumours more accurately. Brain tumours are among the top causes of tumour-relate...
