RECQ1 expression in TMA from human brain glioblastomas. A) Representative immunostaining of RECQ1 expression in tissue core derived from a glioblastoma specimen and B) corresponding normal surrounding tissue (magnification 40×). C) Box plot representing the count of cell positive for RECQ1 in 19 brain glioblastomas and paired peri-lesional tissues independently of the staining intensity of the samples. D) Pie chart presenting the distribution of the staining intensity for RECQ1 in 63 brain glioblastomas and 19 paired peri-lesional tissues E) Box plot representing the count of cell positive for Ki-67 in 19 brain glioblastomas and paired peri-lesional tissues. The boxes summarize the confidence interval (lower and higher horizontal lines), 25th-50th and 75th percentiles (horizontal lines of the box).
