From: Up-regulated oncoprotein P28GANK correlates with proliferation and poor prognosis of human glioma
Immunohistochemical staining of glioma and para-cancerous tissues (A) and Kaplan-Meier analysis of the p28GANK expression associated with the survival time of patients after surgery (B). (A) Staining of p28GANK was observed mainly in the nucleus of glioma cells. a Negative staining (−) of p28GANK in para-cancerous tissues. b Absent staining (−) of p28GANK in glioma cells. c, d Positive staining (+) of p28GANK in grade II glioma cells. e, f Positive staining (+) of p28GANK in grade III glioma cells. g, h Positive staining (+) p28GANK in grade IV glioma cells. Original magnifications: a-c, e and g × 200; d, f, h × 400. (B) Survival rates of total (i), gradeI + II (j) and grade III + IV (k) patients according to the expression of p28GANK.
