Abstract
Background: The malignant features of prostate cancer (PC) threaten the patient's life. MUC1 was observably enhanced in PC. However, the reason for higher MUC1 expression in PC is still unclear and deserves to be further investigated.
Methods: The abundance of MUC1 and E2F4 was evaluated using RT-qPCR in PC patients and PC cells. Pearson correlation coefficient analyzed the relationship between E2F4 and MUC1 in tissues from PC patients. Malignant phenotypes were examined using clone formation, scratch tests, transwell, and flow cytometry. The JASPAR website, luciferase activity assay, and ChIP were employed for validating interplays between E2F4 and the MUC1 promoter.
Results: MUC1 and E2F4 were abnormally elevated in samples of PC patients and PC cells. MUC1 silencing resulted in suppression of growth and metastasis and promotion of cell apoptosis of PC cells. Additionally, E2F4 could provoke the transcriptional activity of MUC1 to enhance MUC1 expression. Furthermore, E2F4 knockdown inhibited malignant features of PC cells, which was abolished by MUC1 overexpression.
Conclusion: Our findings revealed that E2F4 silencing led to the suppression of growth and metastasis and the promotion of cell apoptosis of PC cells through reducing MUC1 expression, which offered targeting molecules for PC treatment.
期刊介绍:
Asia–Pacific Journal of Clinical Oncology is a multidisciplinary journal of oncology that aims to be a forum for facilitating collaboration and exchanging information on what is happening in different countries of the Asia–Pacific region in relation to cancer treatment and care. The Journal is ideally positioned to receive publications that deal with diversity in cancer behavior, management and outcome related to ethnic, cultural, economic and other differences between populations. In addition to original articles, the Journal publishes reviews, editorials, letters to the Editor and short communications. Case reports are generally not considered for publication, only exceptional papers in which Editors find extraordinary oncological value may be considered for review. The Journal encourages clinical studies, particularly prospectively designed clinical trials.
