Key Points

To investigate isoform-specific DNA methylation alterations at the RASSF1 locus in cancer cells.
Examined DNA methylation patterns at the RASSF1 locus
Focused on different isoforms of the RASSF1 gene
Analyzed samples from lung cancer cells
Identified specific methylation changes at the RASSF1 locus
RASSF1A methylation levels showed promise as a minimally invasive biomarker
Findings highlight the significance of isoform-specific regulation

Abstract

These findings highlight isoform-specific epigenetic regulation at the RASSF1 locus and suggest that RASSF1A methylation may represent a promising minimally invasive marker in lung cancer.
