This retrospective study used paraffin archival tissues from women with adenomyosis to examine angiogenesis, apoptosis, and energy metabolism by measuring VEGF, EGF, ICAM-1, and HIF-1A, along with Bcl-2, caspase-9, caspase-3, and the metabolic enzymes IDH1, SDHC, and FH via RT-PCR in ectopic and eutopic endometrial tissue versus controls. VEGF and Bcl-2 expression were increased in ectopic tissue compared with both eutopic tissue and controls, while IDH1 expression was decreased in both ectopic and eutopic tissue versus controls; no significant differences were reported for the other markers. HIF-1A did not differ significantly between groups, though VEGF and HIF-1A were positively correlated in ectopic tissue. The paper concludes that altered VEGF, HIF-1A, Bcl-2, and IDH1 may be associated with adenomyosis etiology, but it is limited by its retrospective design and the focus on expression levels without functional validation. This paper is centrally about adenomyosis—altered VEGF, Bcl-2, and IDH1 (with related HIF-1A) expression across ectopic and eutopic adenomyosis tissues.

Abstract

Purpose Adenomyosis is a benign uterine disease resulting from the myometrial invasion of the endometrial gland and stroma. In the current study, angiogenesis, apoptosis and energy metabolism were investigated in adenomyosis.

Methods

A retrospective study was performed using paraffin archival tissues. Three groups were included in the study: Group I and Group II; ectopic and eutopic endometrial tissues of patients with adenomyosis, respectively, and Control Group; endometrial tissue of individuals without adenomyosis. Vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), intercellular adhesion molecule 1 (ICAM-1) and hypoxia-inducible factor 1 alpha (HIF-1A) levels were evaluated as angiogenic markers. Bcl-2, caspase-9 and caspase-3 levels were investigated as apoptotic indicators, and isocitrate dehydrogenase 1 (IDH1), succinate dehydrogenase complex subunit C (SDHC) and fumarate hydratase (FH) levels were also examined as energy metabolism markers. Gene expression levels of all parameters were determined by RT-PCR.

Result

VEGF expression levels were found to be increased in Group I according to the control group and Group II. Bcl-2 expression levels were found to be increased in the Group I compared to the Group II. It was determined that expression levels of IDH1 were decreased in the Group I and Group II compared to the Control Group. There was no significant difference in the other examined parameters. Although we did not find a significant difference in HIF-1A levels between the groups, we found a positive correlation between VEGF and HIF-1A in the Group I.

Conclusion

These results point out that VEGF, HIF-1A, Bcl-2 and IDH1 may be associated with the etiology of adenomyosis. Similar content being viewed by others
