CART (Cocaine- and Amphetamine-Regulated Transcript): A New Identified Intrafollicular Mediator in Ovulation...

Area of Science:

• Reproductive Endocrinology
• Molecular Biology
• In Vitro Fertilization

Background:

• The study examines the relationship between cocaine- and amphetamine-regulated transcript (CART) expression, leptin, and various hormone profiles.
• It also investigates the role of follicle-stimulating hormone receptor (FSHR) Ser680Asn polymorphisms in relation to CART expression and in vitro fertilization (IVF) outcomes.

Purpose of the Study:

• To understand how CART expression and FSHR polymorphisms influence ovarian response and oocyte quality.
• To explore potential biomarkers for evaluating ovarian outcomes in different ovulation induction protocols.

Main Methods:

• Analysis of hormone levels, CART expression, and FSHR polymorphisms in 94 women undergoing controlled ovarian stimulation for IVF.
• Statistical analysis to determine correlations between CART expression, hormone levels, and IVF results across four ovulation induction protocols.

Main Results:

• CART expression showed a negative correlation with the number of mature follicles, total oocyte count, and oocyte maturity.
• A significant negative association was observed between CART expression and thyroid hormone T3 levels.
• The SER/SER genotype of FSHR polymorphisms was linked to higher CART expression compared to other genotypes.

Conclusions:

• CART expression and FSHR polymorphisms may play a role in determining ovarian response and oocyte quality in IVF.
• These factors could potentially serve as biomarkers for predicting IVF success rates.
