| Project Title: | Identifying a tryptophan derivative in hydrogen peroxide-treated cell culture medium |
| Project Summary: | Reactive oxygen species (ROS) are by-products of metabolism of oxygen and they play an important role in normal homeostasis and cell signaling, as well as in the initiation of diseases including cancer when their production is upregulated. Thus, it is imperative to understand the cellular and molecular basis by which ROS impact on various biological and pathological processes. Here, we identified 2-oxindole, a tryptophan derivative, was a major catabolic product in hydrogen peroxide-treated cell culture medium. We used 2-oxindole to study its role in regulating AhR signaling and tryptophan metabolic pathways. We found that 2-oxindole significantly increased the activity of AhR, leading to enhanced expression of its downstream targets including cytochrome P450 genes. |
