Study IDST002830
Study TitleL-isoleucine in P10 STZ
Study SummarySummary 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.

Project Title:L-isoleucine in P10 STZ (Streptozotocin)
Project Summary:The effects of intraperitoneal L-isoleucine injection in murine hyperglycemia-associated retinopathy, a model mimicking aspects of retinopathy of prematurity (ROP), will be studied. ROP is a leading cause of blindness in children worldwide. Amino acid metabolism is altered in preterm infants. In this study, pups were daily injected with streptozotocin from P1 to P10 to induce hyperglycemia-associated retinopathy. L-isoleucine or PBS control was injected intraperitoneally from P7 to P10. Retinas were collected at P10. 8 retinas (from 4 pups) were pooled to generate 1 sample. 3 samples per group will be compared.
