Özet

Background

Mitochondria is a dynamic organelle that constantly undergoes fusion and fission. These

dynamic processes work in concert to maintain functions of cell and cellular homeostasis. In

process of spermatogenesis, the morphology of mitochondria undergoes significant

modifications, and spermatogonia develop into highly specialized sperm cells that able to

fertilize with perfectly coordinated, healthy mitochondria. Some of major molecules that

mediate mitochondrial fusion and fission have been discovered in mammals, but there are not

yet sufficient studies during spermatogenesis in humans.

Methods

Expression of mitochondrial fusion (OPA1) (MFN1) and mitochondrial fission (MFF) genes as

biomarkers in mitochondrial dynamics was evaluated by RT-PCR in testicular cells taken from

8 infertile men with non-obstructive azoospermia (NOA) and 4 men with obstructive

azoospermia (OA) as the control group.

Results

The expressions of MFN1, OPA1 genes were found to be increased in the NOA group

compared to the OA group. Although the increase in OPA1 gene expression was not

statistically significant, the expression of the MFN1 gene was found to be statistically

significantly increased in the NOA group compared to the OA group.

Conclusion

MFN1 gene expression, which has been investigated for the first time in testicular cells of NOA

patients, may play an important role in mitochondrial fusion in infertile men and may contribute

to the identification of new biomarkers and the development of treatment protocols for infertile

patients with mitochondrial dynamic defects. More clear results will be obtained when the study

is concluded by increasing the number of patients.
