MUC1 is an oncoprotein with a significant role in apoptosis (Review)

Int J Oncol. 2021 Sep;59(3):68. doi: 10.3892/ijo.2021.5248. Epub 2021 Jul 19.ABSTRACTMucin 1 (MUC1) is a membrane‑bound, highly glycosylated protein that is overexpressed in all stages of malignant transformation. Overexpression of MUC1 together with loss of polarization and hypoglycosylation are associated with resistance to apoptosis, which is the process that results in efficient removal of damaged cells. Inhibition of the apoptotic process is responsible for tumor development, tumor progression and drug resistance. MUC1 is considered as an oncogenic molecule that is involved in various signaling pathways responsible for the regulation of apoptosis. Based on this, the aim of the present study was to discuss the involvement of MUC1 in the divergent mechanisms regulating programmed cell death.PMID:34278474 | DOI:10.3892/ijo.2021.5248
