What tumors eat -- and how to poison them | Dr. Christal Sohl | TEDxTulsaCC
TEDx Talks・8 minutes read
Aunt Lizzie's her2-positive breast cancer diagnosis led to research on precision medicine targeting specific mutations like IDH, with a focus on developing drugs that shut down mutant activity while sparing healthy cells to benefit patients. This research shifts the focus from tissue origin to tumor drivers caused by genetic mishaps, presenting new opportunities for targeted treatments like Herceptin over traditional chemotherapy.
Insights
- Precision medicine targets specific mutations in cancer cells, such as the her2-positive subtype, shifting focus from broad chemotherapy to tailored treatments that shut down growth pathways without harming healthy cells.
- San Diego State University's research on tumor drivers like the IDH variant aims to develop drugs that selectively target mutant activity, offering promising solutions for patients like Aunt Lizzie by focusing on the genetic causes of cancer growth.

Recent questions
What is precision medicine?
Precision medicine involves tailoring treatments based on individual genetic makeup.
How do tumor drivers impact cancer treatment?
Tumor drivers are genetic mishaps that cause uncontrolled growth signaling in cancer cells, influencing treatment strategies.
What are tumor metabolism pathways?
Tumor metabolism pathways are specific cellular processes that cancer cells rely on for growth and survival.
What is the role of isocitrate dehydrogenase in cancer?
Isocitrate dehydrogenase mutations can promote tumor growth by altering metabolic reactions in cancer cells.
How does research at San Diego State University contribute to cancer treatment?
Research at San Diego State University focuses on understanding and targeting specific mutations like IDH to develop precision medicines for cancer treatment.

Precision Medicine Targeting Her2-Positive Breast Cancer
- Aunt Lizzie's breast cancer diagnosis led to research on precision medicine, specifically her2-positive subtype treated with Herceptin, contrasting traditional chemotherapy.
- Tumor drivers, caused by genetic mishaps, can lead to uncontrolled growth signaling, like in her2-positive breast cancers, shifting focus from tissue origin to driver mutations for targeted treatments.
- Tumor cells rely on specific pathways for growth, presenting an Achilles heel for precision medicines to strategically shut down these pathways without harming healthy cells.
- Tumor metabolism, especially the role of proteins like isocitrate dehydrogenase (IDH), influences cancer development, with mutations creating new reactions that promote tumor growth.
- Research at San Diego State University focuses on understanding and targeting specific mutations like the troublesome IDH variant, aiming to develop drugs that selectively shut down mutant activity, benefiting patients like Aunt Lizzie.
