Cytochrome-c-oxidase and ATPsynthase content increases in the endometrium of the patients with adenomyosis.
    Molecular biology reports, 2023, Volume: 50, Issue:4

    Adenomyosis is characterized by overgrowth of endometrial glands and stroma in the myometrium and is associated with reduced apoptosis. One of the key participants in one of the pathways of apoptosis is cytochrome c, whose expression can be regulated by actin-binding proteins involved in the formation of structures that provide cell motility. The aim of the study was to determine the content of actin-binding proteins, cytochrome c, and terminal members of the mitochondrial respiratory chain in endometrial biopsies of patients with adenomyosis and the control group.. The content of all studied proteins was determined by Western blotting, and the mRNA content of the corresponding genes was determined by quantitative RT-PCR. The relative content of alpha-actinin1 and mRNA of the gene encoding it in biopsy specimens from patients with adenomyosis was higher than in controls by 86 and 84% (pā€‰<ā€‰0.05), respectively. The relative content of alpha-actinin4 did not change, as did cytochrome c. The content of cytochrome-c-oxidase and ATPsynthase in the group with adenomyosis exceeded the control level by 270 and 121% (pā€‰<ā€‰0.05), respectively, but the relative content of mRNA of these genes did not change, which may indicate a change in regulation at the level of protein synthesis.. The results may indicate a local increase in the synthesis of ATP in pathological endometrial cells, which indicates the possible effectiveness of local application of H+-ATP synthase inhibitors (for example, macrolide antibiotic) to reduce the severity of clinical symptoms of adenomyosis.

The effects of ulipristal on Bax/Bcl-2, cytochrome c, Ki-67 and cyclooxygenase-2 expression in a rat model with surgically induced endometriosis.
    European journal of obstetrics, gynecology, and reproductive biology, 2013, Volume: 169, Issue:2

    To evaluate the effect of ulipristal on Bax/Bcl-2, cytochrome C, Ki-67 and cyclooxygenase-2 expression in surgically induced endometriosis in a rat model.. We conducted a prospective, randomized, controlled, experimental study at the Experimental Research Center of the Iuliu Hatieganu University of Medicine and Pharmacy in Cluj-Napoca, Romania. Endometriosis was induced in 40 female Wistar albino rats by transplanting two autologous fragments of uterine horn onto bowel mesentery. After a 4-week induction period, we formed two groups: the first group was treated with ulipristal (UPA+) for 8 weeks, while the second group was treated only with the vehicle used for ulipristal (UPA-). We measured the volumes and masses of the implants both before and after treatment. A pathologist examined the sections microscopically for histological hallmarks of endometriosis. Immunostaining for Bax/Bcl-2, cytochrome C, Ki-67 and cyclooxygenase-2 (COX-2) was assessed in both groups.. Ulipristal reduced the average implant volume and mass, indicating that the drug is effective (P=0.01). The treatment induced a greater than 50% reduction in the volume and mass of endometrial implants, and the histological findings correspond to this result. The overall Bax positivity rate was higher in the group treated with ulipristal (42.37% vs. 21.05% for UPA+ and UPA-, respectively) (P=0.0062). The overall Bcl-2 positivity rate was smaller in the group treated with ulipristal (15% vs. 40% for UPA+ and UPA-, respectively) (P=0.0593). The cytochrome C global positivity rate was 5% in the UPA- group and increased to 50% in the UPA+ treatment group (P<0.0001). The COX-2 positivity rate decreased from 75% in the UPA- treatment group to 10% in the UPA+ treatment group (P<0.0001) and the Ki67 positivity rate also decreased from 55% in the UPA- group to 10% in the UPA+ treatment group (P<0.0002).. Treatment with ulipristal contributed to the regression and atrophy of endometriotic lesions in rats. The immunohistochemical expression profiles of Bax/Bcl-2 and cytochrome C revealed a pro-apoptotic effect of ulipristal. We also observed a reduced cellular proliferation, indicated by a decrease in Ki-67 expression and an anti-inflammatory effect, shown by a decrease in COX-2 expression after treatment with ulipristal.

[Effect of Neiyi Kangfu suppository on expressions of cytochrome C and survivin in ectopic and eutopic endometrium in rats with endometriosis].
    Zhongguo Zhong xi yi jie he za zhi Zhongguo Zhongxiyi jiehe zazhi = Chinese journal of integrated traditional and Western medicine, 2008, Volume: 28, Issue:2

    To explore the different effects of rectal application of Neiyi Kangfu Suppository (NYKFS) on the expressions of cytochrome C (Cyt C) and Survivin in ectopic and eutopic endometrium in endometriosis (EMT) model rats.. EMT rats were randomly divided into 6 groups, the high- and low-dose NYKFS groups, the Danazol Capsule (DN) group, the Dan'e Fukang Soft Extract (DFE) group, the model group and the blank group. The expressions of Cyt C and Survivin were measured using immunohistochemical SP staining method.. (1) After treatment, the IOD value of Cyt C in ectopic endometrium significantly increased in the high-dose and low-dose NYKFS groups respectively to 6.08 +/- 0.35 and 6.23 +/- 0.35, which was significantly higher than that in the model group (5.07 +/- 0.70) and DFE group (5.98 +/- 1.02) respectively (P < 0.05, P < 0.01); while those of Survivin in ectopic endometrium was significantly decreased to 5.73 +/- 0.93 and 5.62 +/- 0.93 and was significantly lower than that in the model group (6.01 +/- 1.16, P < 0.05 or P < 0.01). (2) The lowered eutopic endometrial level of Cyt C in EMT rats after treatment was significantly higher in the two NYKFS groups than that in the model group (P < 0.05); while that of eutopic endometrial Survivin was insignificantly different between the NYKFS groups and the model group or the blank group (P > 0.05).. NYKFS plays its role in inducing apoptosis by increasing the expression of Cyt C and decreasing the expression of Survivin in ectopic endometrium, but it up-regulates expression of Cyt C, has no obvious effect on Survivin expression in eutopic endometrium.
