Correlation of Beta-2 Adrenergic Receptor Expression in Tumor-Free Surgical Margin and at the Invasive Front of Oral Squamous Cell Carcinoma

Figure 1

Correlation of the averages of β2-AR immunoexpression in OSCC specimens. The lines correspond to the cut-off point that classifies the invasive tumor fronts (green line) and the surgical margins (blue line) as exhibiting weak/negative (averages 0.62 to 23.86) or moderate/strong (averages 25.99 to 79.63) β2-AR expression.
