Yinxing MA earned her master’s degree at the School of Life Sciences at Lanzhou University (China) in 2013. She then did her doctoral and post-doctoral training in France in the Drs. Yegor Vassetzky / Svetlana Dokudovskaya laboratory in CNRS unit UMR9018 at Université Paris Saclay and Gustave Roussy Cancer Research Institute (Villejuif, Paris area). In 2021, she joined the laboratory of Christopher Heeschen as an assistant researcher in the Center for single-cell omics at Shanghai Jiao Tong University School of Medicine.

Research Interest

  • Mitochondrial dysfunction and molecular pathways of disease

  • The role of mitophagy in chemotherapy resistance.

Current Research

Due to late detection and highly metastatic characteristics, pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers in humans. PDAC cells vary in their tumorigenic capabilities with the presence of a subset of PDAC cells known as pancreatic cancer stem cells (CSCs), which are more resistant to currently used therapeutics. Our previous data showed that pancreatic cancer stem cells (CSCs) are especially vulnerable to mitochondrial-targeted therapies (i.e., metformin) due to their reliance on oxidative metabolism. We hypothesized that CSCs activate mitophagy and mitochondrial biogenesis, which coordinately maintain a healthy mitochondrial pool and support tumor growth. We aim to demonstrate the mechanism of mitophagy in regulating the stemness and function of pancreatic cancer stem cells, study the role of mitophagy in chemotherapy resistance, and develop multimodal therapeutic strategies to eliminate cancer stem cells and differentiated cancer cells.
