Sample information

Conclusion: Higher cytoplasmic expression of PPP2R1B (Protein Phosphatase 2 A, Scaffold Subunit Abeta) were each associated with a decreased risk of progression, after adjusting for stage

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : higher cytoplasmic expression

Expression elevation: Expression was evaluated by considering the percentage of cells exhibiting immunoreaction, as well as the localization of signalling (nuclear and/or cytoplasmic).
