HGF/C-MET PATHWAY HAS A ROLE IN TESTICULAR DAMAGE IN DIABETES INDUCED BY STREPTOZOTOCIN

Area of Science:

• Endocrinology
• Reproductive Biology
• Pathology

Background:

• Diabetes mellitus is a systemic disease with significant complications affecting various organs.
• Testicular dysfunction is a recognized complication of diabetes, impacting male reproductive health.
• The specific molecular mechanisms underlying diabetes-induced testicular damage require further elucidation.

Purpose of the Study:

• To investigate the role of the Hepatocyte Growth Factor (HGF)/c-Met signaling pathway in testicular damage caused by streptozotocin (STZ)-induced diabetes.
• To evaluate the impact of insulin treatment on the HGF/c-Met pathway in the context of diabetic testicular injury.

Main Methods:

• Utilized 21 Wistar albino rats, divided into control, STZ-induced diabetic, and insulin-treated diabetic groups (n=7 each).
• Assessed testicular damage through histological examination and Johnsen's scoring.
• Quantified the expression of HGF and c-Met using immunohistochemical staining.

Main Results:

• Diabetic rat testes exhibited seminiferous tubule degeneration, disorganization of spermatogenetic cells, reduced tubule diameter, and lower Johnsen's scores.
• Significantly elevated HGF and c-Met expression was observed in the seminiferous tubule epithelium and spermatogenic cells of diabetic rats.
• Insulin treatment ameliorated morphological damage and decreased the overexpression of HGF/c-Met in diabetic rat testes.

Conclusions:

• The HGF/c-Met pathway appears to play a crucial role in the pathogenesis of diabetes-induced testicular damage.
• Targeting the HGF/c-Met pathway may offer a promising therapeutic strategy for preventing or mitigating testicular complications of diabetes.
