Mitochondrial Function Reveals Connotation of "Seven-Seven" Theory of Huangdi's Internal Classic and Mechanism of Herbal Intervention for Elderly Women Undergoing IVF-ET
To study the changes of mitochondrial function of ovarian granulosa cells in women of different ages and the effect of Erzhi-Tiangui prescription on
in vitro
fertilization-embryo transfer (IVF-ET) outcomes for elderly women, so as to verify the connotation of the "Seven-Seven" theory in the
Huangdi's Internal Classic
(《黄帝内经》).
Method
2
A total of 150 infertility patients undergoing IVF-ET at the Reproductive and Genetic Center of Integrative Medicine, Affiliated Hospital of Shandong University of Traditional Chinese Medicine were recruited and assigned into "hree-Seven/Four-Seven (30 cases), Five-Seven (60 cases), and Six-Seven (60 cases) groups according to the "Seven-Seven" theory
.
The Five-Seven and Six-Seven groups were further assigned into control and Chinese medicine subgroups using the random number plus envelope method, and the Chinese medicine group was administrated with Erzhi Tiangui prescription from the start day of controlled ovulation stimulation cycle to the trigger day. The IVF outcome was observed, and Western blot was employed to determine the levels of mitofusin 1 (MFN1), mitofusin 2 (MFN2), and dynamin-related protein 1 (Drp1) in the ovarian granulosa cells.
Result
2
Compared with the Three-Seven/Four-Seven group, the control subgroups of the Five-Seven and Six-Seven groups showed decreased retrieved oocytes, two pronuclear (2PN) embryos, available embryos, high-quality embryos, clinical pregnancy rate, and live birth rate (
P
<
0.05). Moreover, the control subgroup of the Six-Seven group showed decreased fresh embryo transfer rate(
P
<
0.05). Compared with the control subgroup of the Five-Seven group, that of the Six-Seven group showed reduced retrieved oocytes, 2PN embryos, available embryos, high-quality embryos, and clinical pregnancy rate (
P
<
0.05). The Chinese medicine subgroup had more retrieved oocytes, 2PN oocytes, and available embryos than the control subgroup in the Five-Seven groups (
P
<
0.05). The Chinese medicine subgroup had more retrieved oocytes, than the control subgroup in the Six-Seven groups (
P
<
0.05). The control subgroup of the Six-Seven group showed lower expression levels of Mfn1 and Mfn2 and higher level of Drp1 than the control subgroup of the Five-Seven group (
P
<
0.05), which indicated that the levels of Mfn1 and Mfn2 in ovarian granulosa cells were down-regulated while the expression of Drp1 was up-regulated with aging (
P
<
0.05). The Chinese medicine subgroup had higher Mfn2 level and lower Drp1 level than the control subgroup in the Five-Seven group (
P
<
0.05), and the Chinese medicine subgroup had higher Mfn1 and Mfn2 levels and lower Drp1 level than then control subgroup in the Six-Seven group (
P
<
0.05).
Conclusions
2
The prognosis of IVF in women after "Five-Seven" became worse with aging, and the mitochondria in ovarian granulosa cells showed decreased fusion ability and increased fission, which verified the connotation of the "Seven-Seven" theory from the mitochondrial function. Erzhi Tiangui prescription can regulate the mitochondrial function of ovarian granulosa cells in elderly women, up-regulate the expression levels of Mfn1 and Mfn2 to promote mitochondrial fusion, and down-regulate the expression of Drp1 to reduce mitochondrial fission, thus alleviating the ovarian hypofunction caused by aging, improve the development potential of oocytes, and improve the IVF outcomes of elderly women. However, this prescription has limited efficacy for the elderly women in the age range of "Six-Seven".
