In Silico Characterization and Functional Insights into the Role of GSK-3 Beta in Lung Cancer

Abstract

Background: Glycogen Synthase Kinase 3 Beta (GSK-3β) plays a key role in various biochemical pathways, including those involved in cellular metabolism, tumorigenesis, and oxidative stress responses. Given the increasing recognition of environmental and chemical contributors to cancer development, understanding the molecular characteristics of GSK-3β in lung cancer may offer insights into potential chemical health risks and therapeutic interventions.

Materials and Methods: The amino acid sequence and structure of GSK-3β (PDB ID: 1MQB) were analyzed using multiple in silico tools. Primary sequence analysis was conducted with ProtParam, secondary structure prediction using SOPMA, and 3D modelling via SWISS-MODEL. Structural validation was carried out with PROCHECK. Protein–protein interaction networks were explored using STRING.

Results and Conclusion: GSK-3β demonstrated high structural stability and integrity, supporting its crucial involvement in cancer cell metabolism, autophagy regulation, and tumour progression. STRING analysis revealed a dense interaction network, emphasizing GSK-3β’s centrality in lung cancer pathways. These findings suggest that GSK-3β could serve as a molecular link between biochemical dysregulation and potential chemical-induced carcinogenesis, warranting further investigation from both therapeutic and health risk perspectives.
