Breast cancer methylation age analysis with the incorporation of vital status and clinical information
Shuying Sun
Texas State University

Abstract: Breast cancer is associated with epigenetic changes such as DNA methylation and risk factors like
age, which itself is also linked to methylation changes. Previous studies have developed models to estimate
age from DNA methylation (DNAm age), such as the Horvath clock (with 353 CpG sites). Prior research has
used such clocks to analyze methylation in breast cancer. However, to our knowledge, no prior analysis has
considered patients’ vital status, and the original Horvath clock was not built with breast cancer-specific
clinical information such as hormone receptor status (ER and PR) or tumor stage in mind.
To address these gaps, we conducted a two-part DNAm age analysis using publicly available breast cancer
methylation data, stratified by vital status (Alive, Dead) and tissue type (Tumor, Matched Normal) into four
datasets: Alive Normal, Alive Tumor, Dead Normal, and Dead Tumor. In Part I, we examined relationships
between DNAm age, chronological age, clinical information and differentially methylated (DM) sites across
the four groups. In Part II, we built a regression model for each CpG site, with methylation level as the
response and chronological age, ER status, and PR status as covariates, and identified CpG sites where
methylation was significantly associated with age within each dataset. We further studied these sites and
their associated genes.
Our findings provide the first systematic comparison of DNAm age patterns between alive and dead breast
cancer patients. We show that vital status and clinical information are critical but previously overlooked axis
of variation in epigenetic aging analysis. This work offers a new understanding of DNAm age in breast cancer
and lays the groundwork for breast cancer-specific, vital-status-aware biomarkers for diagnosis, prognosis,
and treatment. Click here for more information
