Figure 3From: Changes in circulating microRNAs after radiochemotherapy in head and neck cancer patientsCell viability (XTT-assay) of primary HNSCC cell cultures. Absorption was measured 24 h after exclusive 5-FU treatment and 5-FU treatment in combination with 2 x 2 Gy in vitro irradiation relative to DMSO-controls. Error bars represent the standard deviation of three biological replicates (*p < 0.05, **p < 0.01).Back to article page
