Core Tip

Core tip: Crohn’s disease is associated with an imbalance, comprising increased reactive oxygen species (ROS) and decreased net antioxidant activity. A deficiency in antioxidant molecules could lead to increased levels of lipid peroxides or ROS, which could act locally or be secreted into the circulation to produce different systemic effects in the patient. Future research should address the question of whether ROS are involved in increasing the production of the different extracellular proteins by enhancing the transcriptions of certain genes using specific transcription factors.
