Role of Endogenous Serotonin Replica Mediated Through β-Catenin/Wnt Signaling in Lung Cancer Prevention and Prognosis - an in-vitro Study in A549 Cancer Cell Lines

Abstract

Background: Lung cancer is still the most common cause of carcinoma-related death in the globe. Non-pharmacological treatments such as physical activity and exercise have been shown to improve quality of life and provide better results in lung cancer patients. Lung cancer patients usually lack adequate amounts of physical activity and exercise, both of which can improve quality of life.
 Aim: To analyse Chemotherapeutic potential of endogenous serotonin replica mediated through β-catenin/Wnt signaling in lung tumor cell lines (A549).
 Methods and Materials: The National Centre for Cell Sciences (NCCS), Pune, India, provided the human lung cancer cell line (A549). MTT assay was used to determine cell viability. Real-time PCR was used to examine -Catenin mRNA, Wnt mRNA, and GSK mRNA gene expression. The significance of the acquired data was determined using one-way analysis of variance and Duncan's multiple range test with Graph Pad Prism version 5. Duncan's test was used to determine significance at the 0.05 level.
 Results: The Results suggest that maximum inhibition of cell growth was at concentration (2-4 mM/ml) used in this study when compared to control. The cancer cells were significantly inhibited and it was found that there was notable reduction in GSK mRNA gene expression, β-Catenin, Wnt when compared to control at a dose of 2 mM/ml.
 Conclusion: It may be concluded, based on the analyses' findings and the study's limitations, that the role of exercise induced endogenous serotonin may act as the regulator of wnt/β-catenin signaling in lung cancer cells. The exercise may help in maintaining the equilibrium of the gene expression by modeling Wnt/β-catenin signaling pathway and act as a protective factor in prevention.
