Figure 3. β-adrenergic receptor (β-AR) expression in oral cancer cells.

Figure 3.

RT-qPCR was used to quantify relative ADRB1 (A) and ADRB2 (B) gene expression in oral cancer (HSC-3, SCC-4) and dysplastic (DOK) cells compared to non-tumorigenic skin keratinocytes (HaCaT). Data is presented as the relative gene expression (2−ΔCT) normalized to ACTB and represent three different cell passage determinations of gene expression. *p<0.05, **p<0.01. C) Representative images of β-AR2-IR (green) in DOK, HSC-3, and SCC-4 cell lines. DAPI (blue) was used to label cell nuclei.
