Abstract
Cell adhesion molecule 1 (CADM1), an immunoglobulin superfamily member, is expressed in endometrial glandular cells highly during the proliferative phase but lowly during the secretory phase. Previously, a CADM1-targeting antibody-drug conjugate (ADC) was generated, in which a humanized anti-CADM1 ectodomain antibody h3E1 was linked with monomethyl auristatin E (h3E1-MMAE ADC). The present study aimed at probing whether this ADC could be useful for the treatment of endometrial neoplasm. Firstly, immunohistochemistry for CADM1 was conducted on proliferative-phase endometrium (n = 13), endometrial hyperplasia (n = 35), and endometrioid carcinoma at various stages (n = 166). CADM1 immunostaining intensity was highest in atypical endometrial hyperplasia and endometrioid carcinoma confined within the endometrium and was decreased stepwise as the carcinoma stage progressed. Next, h3E1-MMAE ADC was examined for its cytotoxicity in vitro using human endometrial adenocarcinoma cell lines expressing CADM1; HEC-1B, HEC-50B, JHUM-3, and OMC-2. The ADC killed these cells in a dose-dependent manner with half maximal inhibitory concentration (IC50) of 12.02 nM for HEC-1B and 2.04 nM for HEC-50B. Collectively, h3E1-MMAE ADC may serve as a noninvasive alternative to simple hysterectomy in the treatment of endometrioid carcinoma confined within the endometrium.
期刊介绍:
For a long time, solid neoplasms have been viewed as relatively homogeneous entities composed for the most part of malignant cells. It is now clear that tumors are highly heterogeneous structures that evolve in the context of intimate interactions between cancer cells and endothelial, stromal as well as immune cells. During the past few years, experimental and clinical oncologists have witnessed several conceptual transitions of this type. Molecular and Cellular Oncology (MCO) emerges within this conceptual framework as a high-profile forum for the publication of fundamental, translational and clinical research on cancer. The scope of MCO is broad. Submissions dealing with all aspects of oncogenesis, tumor progression and response to therapy will be welcome, irrespective of whether they focus on solid or hematological neoplasms. MCO has gathered leading scientists with expertise in multiple areas of cancer research and other fields of investigation to constitute a large, interdisciplinary, Editorial Board that will ensure the quality of articles accepted for publication. MCO will publish Original Research Articles, Brief Reports, Reviews, Short Reviews, Commentaries, Author Views (auto-commentaries) and Meeting Reports dealing with all aspects of cancer research.
