Oxidative stress, unfolded protein response, and apoptosis in developmental toxicity

Area of Science:

• Developmental Biology
• Toxicology
• Cellular Stress Responses

Background:

• Precise spatiotemporal regulation of cellular and molecular processes is crucial for physiological development.
• Disruptions in development can lead to teratogenesis or mortality, with mechanisms often unknown.
• While oxidative stress, unfolded protein response (UPR), and apoptosis are studied in disease, their role in developmental toxicity is less understood.

Purpose of the Study:

• To review the current knowledge on the role of oxidative stress, UPR, and apoptosis in physiological development.
• To examine the involvement of these cellular processes in developmental toxicity.
• To focus on advances and studies in vertebrate model systems.

Main Methods:

• Literature review of existing studies and research.
• Focus on vertebrate model systems to understand mechanisms.
• Analysis of the interplay between redox regulation, UPR, and apoptosis in developmental toxicity.

Main Results:

• Redox regulation, UPR, and apoptosis are fundamental to normal physiological development.
• These essential processes can be perturbed by endogenous and exogenous toxicants.
• Perturbations can result in lethality and a range of malformations.

Conclusions:

• Oxidative stress, UPR, and apoptosis are critical pathways implicated in developmental toxicity.
• Understanding these mechanisms is key to identifying and mitigating developmental toxicants.
• Further research in vertebrate models is needed to elucidate these complex relationships.
