p16INK4a and DNA methylation clocks in women treated with chemotherapy for early breast cancer.
Candidate biomarkers of biologic aging include p16INK4a (p16) expression in peripheral blood T cells, a marker of cellular senescence, and whole-blood DNA methylation (DNAm) clocks, markers of epigenetic aging. Both have been associated with age-accelerating conditions, including cancer and chemotherapy, but their rela...
