Abstract
Nectin-3 and nectin-4 belong to the immunoglobulin (Ig) superfamily, and are Ca2+ -independent homophilic cell adhesion molecules. Nectin-3 is ubiquitous in adult tissues, and it enhances normal levels of synaptic formation. In contrast, nectin-4 is weakly-to-moderately expressed in normal human tissues. In recent years, studies have shown that nectin-3 is highly expressed in the nervous system. Moreover, it is associated with poor prognostic factors in distant metastases and malignant tumors with high vascular invasion such as pancreatic, lung and breast cancers. In particular, nectin-4 is overexpressed in various malignant tumors, and it is associated with proliferation, angiogenesis, metastasis, drug resistance, tumor relapse, DNA repair, cancer stemness, and poor prognosis. Unlike nectin-3, nectin-4 has become a potential prognostic biomarker and specific therapeutic target for cancer as there is no consensus on the significance of abnormal expression of nectin-3 in various cancers.
期刊介绍：
We seek to encourage pharmaceutical and allied research of tropical and international relevance and to foster multidisciplinary research and collaboration among scientists, the pharmaceutical industry and the healthcare professionals.
We publish articles in pharmaceutical sciences and related disciplines (including biotechnology, cell and molecular biology, drug utilization including adverse drug events, medical and other life sciences, and related engineering fields). Although primarily devoted to original research papers, we welcome reviews on current topics of special interest and relevance.
