Laryngeal cancer is the most common head and neck cancer in the world and its incidence is on the rise. However, the
molecular mechanism underlying laryngeal cancer pathogenesis is poorly understood. The goal of this study was to
develop a protein-protein interaction (PPI) network for laryngeal cancer to predict the biological pathways that underlie
the molecular complexes in the network. Genes involved in laryngeal cancer were extracted from the OMIM database
and their interaction partners were identified via text and data mining using Agilent Literature Search, STRING and
GeneMANIA. PPI network was then integrated and visualised using Cytoscape ver3.6.0. Molecular complexes in the
network were predicted by MCODE plugin and functional enrichment analyses of the molecular complexes were performed
using BiNGO. 28 laryngeal cancer-related genes were present in the OMIM database. The PPI network associated with
laryngeal cancer contained 161 nodes, 661 edges and five molecular complexes. Some of the complexes were related to
the biological behaviour of cancer, providing the foundation for further understanding of the mechanism of laryngeal
cancer development and progression.
