Fig. 1From: Modulating tumour metabolism enhances gold nanoparticle radiosensitisation in HPV-negative head and neck cancerCell uptake of AuNPs in FaDu (a), CAL27 (b) and CAL33 (c) cells under atmospheric (21% O2) or hypoxic (0.5% O2) conditions. One-way ANOVA followed by Turkey’s multiple tests was used to compare within different concentrations, * p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. Data were obtained from three independent experiments performed in triplicate ± SEMBack to article page
