Despite a lack of differences seen in PANX1 mRNA levels (Fig. 11B, P = 0.9254) between tissue types, immunoblotting exhibited a significant increase in cSCC tumour PANX1 levels compared to patient‐matched normal skin (containing epidermis and dermis only) controls (Fig. 11C,D, P = 0.0011). The gene discussed is PANX1; the disease is skin squamous cell carcinoma.
