Increased aquaporin 1 water channel expression in human brain tumours

Br J Cancer. 2002 Sep 9;87(6):621-3. doi: 10.1038/sj.bjc.6600512.

Abstract

Aquaporin 1 is a water channel protein. There was little aquaporin 1 immunoreactivity in normal brain parenchyma. In astrocytomas, aquaporin 1 was expressed in microvessel endothelia and neoplastic astrocytes. In metastatic carcinomas, aquaporin 1 was present in microvessel endothelia and reactive astrocytes. Aquaporin 1 may participate in the formation of brain tumour oedema.
