NIH-funded research R21 grant

Investigating how cancer cells manage damaged mitochondria

Official title: Secretory Mitophagy in Cancer Metabolic Reprogramming

Funded at George Mason University · NIH-10886109 · Data updated 2026-11-12

This study is looking at how cancer cells manage to stay alive by getting rid of damaged parts inside them, especially when they face tough treatments like immunotherapy and radiotherapy, and it hopes to find new ways to make these cells more vulnerable to treatment.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with breast cancer who are undergoing or have undergone treatments that induce oxidative stress.

Less likely to help

Patients with non-cancerous conditions or those not affected by mitochondrial dysfunction may not benefit from this research.

What this research studies

This research explores a process called secretory mitophagy, which helps cancer cells survive by removing damaged mitochondria. By studying how these cells adapt their metabolism in response to stress from treatments like immunotherapy and radiotherapy, the researchers aim to understand how cancer cells maintain their viability. The approach involves analyzing extracellular vesicles in tumor interstitial fluid to gather insights into mitochondrial health within tumors. This could lead to new strategies for targeting cancer cell survival mechanisms.

Why it matters

Potential benefit: If successful, this research could lead to innovative treatments that improve the effectiveness of cancer therapies by targeting the survival mechanisms of cancer cells.

How similar studies have gone: While the concept of mitophagy has been studied, the specific focus on secretory mitophagy in cancer is relatively novel and has not been extensively tested.
