Riboceine Rescues Auranofin-Induced Craniofacial Defects in Zebrafish.

Area of Science:

• Developmental Biology
• Toxicology
• Genetics

Background:

• Craniofacial abnormalities are common congenital disorders often requiring surgical intervention.
• Neural crest cells (NCCs) are crucial for facial development but are vulnerable to oxidative stress.
• Auranofin (AFN) is an oxidative stress-inducing compound known to disrupt craniofacial development.

Purpose of the Study:

• To investigate the potential of the antioxidant Riboceine (RBC) in rescuing craniofacial defects induced by AFN exposure.
• To evaluate the impact of RBC on cellular apoptosis and cranial cartilage development in zebrafish embryos.

Main Methods:

• Zebrafish embryos were exposed to AFN to induce craniofacial developmental defects.
• RBC was administered to assess its protective effects against AFN-induced abnormalities.
• Cellular apoptosis and gene expression of antioxidant markers (gstp1, prxd1) were analyzed.

Main Results:

• RBC treatment effectively rescued AFN-induced cellular apoptosis and defects in cranial cartilage.
• AFN exposure led to increased expression of antioxidant genes gstp1 and prxd1.
• RBC partially restored the expression levels of these antioxidant genes.

Conclusions:

• Antioxidants like RBC show promise in mitigating craniofacial cartilage defects caused by environmental or genetic factors.
• RBC enhances cellular survival, offering a potential therapeutic strategy for preventing developmental abnormalities.
