Increased prolidase activity and oxidative stress in PCOS

Area of Science:

• Biochemistry
• Endocrinology
• Reproductive Medicine

Background:

• Matrix metalloproteinases (MMPs) are implicated in pathological processes like inflammation and cardiovascular disease.
• Prolidase, a potential MMP, has roles in tissue remodeling and may be involved in ovarian dysfunction.
• Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age.

Purpose of the Study:

• To investigate serum prolidase activity in women with PCOS compared to healthy controls.
• To evaluate the oxidative and antioxidative status in PCOS patients.
• To explore the biochemical markers associated with PCOS.

Main Methods:

• Serum prolidase activity, total antioxidant status (TAS), and total oxidant status (TOS) were measured.
• Oxidative stress index (OSI) was calculated.
• Hormonal levels including LH, FSH, testosterone (T), and prolactin (PRL) were assessed in 33 PCOS patients and 28 healthy women.

Main Results:

• PCOS patients exhibited significantly higher serum prolidase activity, TOS, OSI, LH, PRL, and T levels compared to controls.
• Total antioxidant status (TAS) was lower in the PCOS group, though not statistically significant.
• Follicle-stimulating hormone (FSH) levels did not differ significantly between the groups.

Conclusions:

• Women with PCOS demonstrate elevated serum prolidase activity and increased oxidative stress.
• These findings suggest a potential link between increased prolidase activity, oxidative stress, and cardiovascular risk in PCOS.
• Elevated markers may also be associated with the menstrual irregularities characteristic of PCOS.
