Expression data from PARK2 overexpression in U251 cells

ABSTRACT: PARK2 (PARKIN) is an E3 ubiquitin ligase whose dysfunction has been associated with the progression of Parkinsonism and human malignancies, and its role in cancer remains to be explored. In this study, we investigated its role in glioma. We used microarrays to detail the global programme of gene expression upon PARK2 overexpression in U251 cells U251 cells with PARK2 overexpression or control (GFP) were subjected for RNA extraction and hybridization on Affymetrix microarrays.

PARK2 (PARKIN) is an E3 ubiquitin ligase whose dysfunction has been associated with the progression of Parkinsonism and human malignancies, and its role in cancer remains to be explored. In this study, we report that PARK2 is frequently deleted and underexpressed in human glioma, and low PARK2 expression is associated with poor survival. Restoration of PARK2 significantly inhibited glioma cell growth both in vitro and in vivo, whereas depletion of PARK2 promoted cell proliferation. PARK2 attenua  ...[more]
