Correlation between PPARγ protein expression level in granulosa cells and pregnancy rate in IVF program

Area of Science:

• Reproductive biology
• Molecular endocrinology
• In-vitro fertilization (IVF) research

Background:

• Peroxisome proliferative-activated receptors (PPARs) are nuclear receptors regulating lipid metabolism and cellular differentiation.
• PPARγ, a specific subtype, is crucial for ovarian physiological functions.

Purpose of the Study:

• To investigate the potential correlation between PPARγ protein levels in granulosa cells and pregnancy rates in women undergoing IVF.
• To assess if PPARγ expression serves as a biomarker for IVF treatment success.

Main Methods:

• A cross-sectional study involving 25 granulosa cell samples from women undergoing IVF.
• Western blot analysis was used to quantify PPARγ protein expression relative to β-actin.
• Pregnancy was confirmed by elevated blood β-hCG levels 14 days post-embryo transfer.

Main Results:

• No significant relationship was found between granulosa cell PPARγ protein levels and key IVF parameters (oocyte maturation, fertilization ratio).
• PPARγ protein levels did not correlate significantly with laboratory-confirmed pregnancy (positive or negative).

Conclusions:

• PPARγ protein expression in granulosa cells is not directly associated with the success rate of IVF treatments.
• Current findings do not support PPARγ as a predictive marker for IVF outcomes.
