Statistical analysis Data are represented as the mean standard deviation (SD) from at least three individual experiments. Differences between groups were analyzed by one-way analysis of variance (ANOVA) or assessments. Overall survival time was measured from the date of diagnosis to the date of death or last follow-up. Survival analyses were performed using the Kaplan-Meier method, and the log-rank test was used to identify significant differences. Univariate and multivariate analyses were performed using the Cox proportional-hazards regression model. All statistical analyses were performed with SPSS Statistics version 20.0 and GraphPad Prism version 6.0 statistical software. 0.05 was considered ALPS statistically significant. Results YAP expression is elevated in DLBCL and positively associated with disease progression To elucidate the potential role of YAP in human cancers, we first examined the expression of YAP in data from the Oncomine database [24]. YAP expression levels were upregulated (tumor versus normal) in 6 out of 29 lymphoma datasets using the threshold of 2-fold change and value 0.0001 (Figure S1). We next analyzed the microarray datasets [25] obtained from the Oncomine database to illuminate the YAP mRNA transcriptional alterations between normal B cells and DLBCL samples. As shown in Fig. ?Fig.1a,1a, the mRNA level of YAP was significantly elevated in the DLBCL tissue samples ( 0.01). To assess the protein expression level of YAP in DLBCL patients, YAP expression was detected by IHC in a cohort of DLBCL primary samples (= 60) diagnosed at Shandong Provincial Hospital Affiliated to Shandong University. Compared to reactive lymphoid hyperplasia, DLBCL patients showed significantly higher levels of YAP (Fig. ?(Fig.1b).1b). High YAP expression (YAPhigh) was detected in 60% (36/60) of the DLBCL primary samples but only 23.3% (7/30) of the reactive lymphoid hyperplasia tissue samples (= 0.001). Upregulation of YAP expression was validated in DLBCL cell lines. Consistently, the YAP expression level was significantly higher in human DLBCL cell lines than in normal B lymphocytes (Fig. ?(Fig.11c).

YAP appearance levels had been upregulated (tumor versus regular) in 6 out of 29 lymphoma datasets using the threshold of 2-flip change and worth 0.0001 (Figure S1). We following examined the microarray datasets [25] extracted from the Oncomine data source to illuminate the YAP mRNA transcriptional modifications between regular B cells and DLBCL examples.
