Figure 2From: A pool of peptides extracted from wheat bud chromatin inhibits tumor cell growth by causing defective DNA synthesis Cell growth inhibition of tumour cell lines induced by the peptide fraction. HeLa (a) and U2OS (b) cells were treated with 1 μg/ml (white) and 2 μg/ml (black) of peptide pool for 1, 2 and 4 days. Gray bars represent untreated controls. Error bars show the standard deviation obtained from three independent experiments. Student’s test. *p < 0.05 **p < 0.01.Back to article page
