Transcriptional Profile of Bovine Preimplantation Development Selected Based on G6PDH Activity

Introduction: Understanding the molecular mechanisms behind bovine preimplantation development is essential for improving reproductive efficiency and embryo viability. This study explores the role of glucose-6-phosphate dehydrogenase (G6PDH) activity in selecting competent oocytes, shedding light on key transcriptional profiles that influence early embryonic development.

Main Content Sections:

• Oocyte Quality and Developmental Competence: Oocytes play a crucial role in embryo development by providing genetic and cytoplasmic components necessary for early-stage growth. The competence of an oocyte can influence implantation success and embryo yield.
• G6PDH Activity and Brilliant Cresyl Blue (BCB) Test: The study highlights how G6PDH activity, assessed using the Brilliant Cresyl Blue (BCB) test, helps in distinguishing between competent and incompetent oocytes.
• Molecular Markers and Gene Expression: Findings indicate that competent oocytes (BCB+) exhibit higher expression of genes linked to mitochondrial activity, nuclear reprogramming, and anti-apoptotic pathways, enhancing embryo quality and implantation potential.
