Laura Castellini studies the effects of the cancer drug Sorafenib in liver cancer, specifically how it interacts with cancer cells and affects their metabolism. She discovered that when Sorafenib is combined with methods that block the breakdown of sugars (glycolysis), it becomes significantly more effective at killing cancer cells. Additionally, her research examines how stem cells derived from bone marrow and fat tissue can maintain their ability to renew themselves and what genes are involved in this process. This research can lead to improved therapies for various conditions, including those requiring regenerative medicine.
Key findings
Sorafenib alone had a limited effect on liver cancer cells, but when glucose was blocked or glycolysis was inhibited, the drug's effectiveness increased significantly, indicating a potential treatment strategy.
In her study on stem cells, Castellini identified 190 critical genes that play a role in maintaining the self-renewal capability of stem cells, particularly highlighting the function of the protein KLF4.
The research sheds light on the mechanisms that control whether stem cells change into different types of cells, which can enhance applications in regenerative therapies.
