Figure 4From: Activation of P2X7-mediated apoptosis Inhibits DMBA/TPA-induced formation of skin papillomas and cancer in mice Summary of the effects of local treatments with DMBA/TPA (black symbols) or DMBA/TPA+BzATP (white symbols) on the mean number of skin lesions per living animal (Experiment-1). Definitions of lesions were as in Fig. 4. Values in A-C are means; SD ranged 5–9%.Back to article page
