Purpose:
Music has recognized beneficial effects on cancer patients; however, very little is known about the molecular processes which produce these benefits. The aim of this work was to evaluate the effect of music on proliferation and gene expression in gastric cancer cells.
Methods:
AGS gastric cancer cells were exposed to metal and classical music, and subsequently cell proliferation and expression of genes associated with apoptosis and cell-cycle control were evaluated.
Results:
Proliferation of AGS cells increased when exposed to metal music, but not when exposed to classical music. Gene expression of caspase-3 and 8 and cyclin B1 increased in response to both musical genres; classical music repressed the expression of p53, and metal music repressed the expression of PUMA.
Conclusions:
This is the first study to demonstrate music as a modulator of gene expression in a cancer cell line. Additional experiments are required to better understand the mechanisms of how different musical genres can induce changes in gene expression.

01:42What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
