Retinoic acid signaling pathways in development and diseases

Area of Science:

• Biochemistry
• Molecular Biology
• Developmental Biology

Background:

• Retinoids are essential compounds involved in regulating cell development, differentiation, proliferation, and apoptosis.
• They function by binding to nuclear receptors, retinoic acid receptors (RARs) and retinoid X receptors (RXRs).
• Proper retinoid signaling is vital for numerous organ systems, while its deregulation can lead to severe diseases.

Purpose of the Study:
