Modeling Isocitrate Dehydrogenase 2 Mutations In Acute Myeloid Leukemia: Exploring How The Drug Ag-221 Inhibits 2-Hydroxyglutarate Production And Restores Blood Cell Differentiation, Bhumika Balani, Jay Matta, Brianna Bourke, Nitya Punjal, Melissa Dore Ph.D.

Undergraduate Student Symposium

Mutations in the Isocitrate Dehydrogenase 2 (IDH2) enzyme have been linked to acute myeloid leukemia (AML). IDH2, involved in the citric acid cycle, normally converts isocitrate to α-ketoglutarate (α-KG), using NADP+ to produce NADPH. Mutations like R140Q and R172K lead IDH2 to convert αKG into the oncometabolite 2-hydroxyglutarate (2HG), hindering blood cell differentiation and resulting in AML.

The drug AG-221 targets mutant IDH2 at an allosteric site, stabilizing the enzyme in an inactive form and preventing 2HG formation, thus alleviating AML symptoms. Most patients, however, require additional chemotherapy and often complete bone marrow transplants. A 3-D printed model based on …

Patel, Earlissa Tucker, Rishubh Madaboosi, Mehtab Singh

Undergraduate Student Symposium

In 1915, Frederick William Twort and Felix d’Herelle discovered bacteriophages (phage), viruses that kill bacteria. As this was prior to the discovery of antibiotics, their work led to early development of phage therapy, treatment that involves the use of phage to selectively kill bacterial. Today, phage therapy provides an alternative to antibiotics especially by targeting specific pathogens that are normally resistant to multiple treatments. Even with its ability to alleviate the antibiotic-resistant problem, the vast majority of phage remains uncharacterized. Therefore, it is important to expand bacteriophage discovery-based and genome characterization research. Through the SEA-PHAGES (Science Education Alliance – Phage …
