Moreover, Ki67 expression positively correlated with TUNEL labelling, such that the stained Ki67 proliferation factor-positive cells were relatively decreased, whereas the labelled TUNEL-positive cells were relatively increased in the tumour sections exposed to miR-12528 for 4 weeks compared with the NC and ASO-12528 tumour tissue sections (Fig. 4c). The gene discussed is MKI67; the disease is neoplasm.
