How mitochondrial DNA affects breast aging and cancer subtype

Understanding the influence of Mitochondrial DNA haplotypes on breast aging and cancer

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11296919

This project looks at whether differences in mitochondrial DNA change how breasts age and which type of breast cancer women may develop.

What this research studies

You would be asked to help researchers link mitochondrial genetic differences to changes in breast cells as women get older. Scientists will analyze human breast tissue and use single-cell RNA sequencing and protein measurements (including SIRT3 and ERα pathways) to compare cell types that age differently. The team will combine those human sample results with laboratory models to see how different mitochondrial haplotypes influence cell aging and cancer-related changes. The work aims to find biological markers that could explain why some women develop certain breast cancer subtypes as they age.

Who could benefit from this research

Good fit: Ideal candidates would be adult women willing to provide breast tissue samples or clinical data, including older women and those with or without a history of breast cancer.

Not a fit: People who cannot provide tissue or clinical information, or whose condition is unrelated to breast biology (for example many male patients), are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could identify mitochondrial markers that help predict breast aging and cancer subtype, which may guide earlier detection or tailored prevention strategies.

How similar studies have performed: Previous single-cell studies have linked mitochondrial decline and SIRT3 to aging in breast cells, but applying mitochondrial haplotypes to predict cancer subtype is a relatively new approach.
