Gene expression analysis results. a miR-155 expression in HeLa cells after treatment with PS-155 containing PLGA NPs. miR-155 expression relative to average control (all normalized to U6, n = 3, *p < 0.05). b Dose-dependent effect in miR-155 expression level in HeLa cell lines after treatment with different doses of PS-155/NLS containing PLGA NPs (all normalized to U6 control, n = 3, *p < 0.05)
