TRPC5 expression was significantly lower in basal cell carcinomas compared to squamous cell carcinomas (p < 0.001 Kruskal–Wallis and post hoc Bonferroni tests), as well as between BCC and MM epidermal section (p-value 0.039 Kruskal–Wallis and post hoc Bonferroni tests) and between BCC and NCN epidermal section (p-value < 0.001 Kruskal–Wallis and post hoc Bonferroni tests). The gene discussed is TRPC5; the disease is skin basal cell carcinoma.
