Fig. 1From: Adenosine A2b receptor promotes progression of human oral cancerEvaluation of ADORA2B expression in OSCC-derived cell lines. a Quantification of ADORA2B mRNA expression in OSCC-derived cell lines by qRT-PCR analysis. Significant (p < 0.05, Mann–Whitney U test) up-regulation of ADORA2B mRNA is seen in seven OSCC-derived cell lines compared with the HNOKs. Data are expressed as the means ± SEM of triplicate results. b Representative immunoblotting analysis of ADORA2B protein in OSCC-derived cell lines and HNOKs. ADORA2B protein expression is up-regulated in OSCC-derived cell lines compared with the HNOKs. Densitometric ADORA2B protein data are normalized to α-tubulin protein levels. The values are expressed as a percentage of the HNOKsBack to article page
