We describe a method that assesses the impact of specific mutations of TP53 and genomic instability on gene expression of the most important genes involved in telomere length and structure homeostasis. The approaches consist of using a reverse transcriptase method and a quantitative PCR that were applied to isogenic cell lines from a colon cancer.
