Glucose Uptake Is Increased by Estradiol dipropionate in L6 Skeletal Muscle Cells
Pharmaceuticals (Basel) 2022 Dec 25;16(1):25.PMID:36678522DOI:10.3390/ph16010025.
GLUT4 is an important glucose transporter, which is closely related to insulin resistance and type 2 diabetes. In this study, we investigated the mechanism of Estradiol dipropionate (EDP) on uptake of glucose in L6 skeletal muscle cells. In our study, we confirmed that EDP promoted uptake of glucose in L6 skeletal muscle cells in both normal and insulin resistant models. Western blot indicated that EDP accelerated GLUT4 expression and significantly activated AMPK and PKC phosphorylation; the expression of GLUT4 was significantly inhibited by AMPK inhibitor compound C and PKC inhibitor Gö6983, but not by Wortmannin (Akt inhibitor). Meanwhile, EDP boosted GLUT4 expression, and also increased intracellular Ca2+ levels. In the presence of 2 mM, 0 mM extracellular Ca2+ and 0 mM extracellular Ca2+ + BAPTA-AM, the involvement of intracellular Ca2+ levels contribute to EDP-induced GLUT4 expression and fusion with plasma membrane. Therefore, this study investigated whether EDP promoted GLUT4 expression through AMPK and PKC signaling pathways, thereby enhancing GLUT4 uptake of glucose and fusion into plasma membrane in L6 skeletal muscle cells. In addition, both EDP induced GLUT4 translocation and uptake of glucose were Ca2+ dependent. These findings suggested that EDP may be potential drug for the treatment of type 2 diabetes.
Embryo collection from pigs post-pseudopregnancy induced by Estradiol dipropionate
Anim Sci J 2019 Dec;90(12):1523-1529.PMID:31646735DOI:10.1111/asj.13303.
We aimed to define whether embryo collection carried out after pseudopregnancy was of similar outcome and quality as after artificial abortion. To induce pseudopregnancy, 30 gilts or sows were given 20 mg intramuscular Estradiol dipropionate (EDP) 10-11 days after the onset of estrus. Ten additional pigs were inseminated artificially at natural estrus as a control group. Prostaglandin F2α (PGF2α ) was administered twice with a 24 hr interval beginning 15, 20, or 25 days after EDP-treatment (n = 10 per group) or between 23 and 39 days after artificial insemination in control pigs. Following this, all pigs were given 1,000 IU equine chorionic gonadotropin and 500 IU human chorionic gonadotropin (hCG) and then inseminated. Embryos were recovered 6 or 7 days after hCG treatment and outcome was recorded. There was no significant difference in the number of normal embryos collected from the pigs with PGF2α initiated at different time points or from the control group. Embryonic developmental stages 7 days after hCG treatment also did not differ among groups. These results indicate that the use of EDP to induce pseudopregnancy, followed by PGF2α administration to synchronize estrus for subsequent embryo harvest, is a suitable alternative to the artificial abortion method.
Antagonistic effects of Estradiol dipropionate and progesterone on the histology of the vagina and uterus of the mouse
J Exp Zool 1984 Oct;232(1):151-5.PMID:6502091DOI:10.1002/jez.1402320118.
Administration of Estradiol dipropionate (20 micrograms/day; 7 days) to ovariectomized mice caused heavy epithelial proliferation and intense cornification in the vagina and cellular as well as glandular proliferation in uterine tissues. Endometrial hypertrophy with cystlike appearance of uterine glands was seen in response to a long-term (14 days) administration of Estradiol dipropionate. Daily injection of progesterone (2 mg; 7 days) to ovariectomized mice resulted in desquamating mucosa, without any trace of vaginal cornification, and the presence of dense uterine connective tissue in the stromal region with typical uterine glands. However, treatment of estradiol depropionate in combination with progesterone at 1:100 dose ratio for 7 days produced vaginal histology similar to that in proestrus and uterine histology equivalent to the ovariectomized condition. The results revealed that progesterone antagonized the estrogenic effects and also that Estradiol dipropionate antagonized the effects of progesterone. The effects of the two female sex steroids (Estradiol dipropionate and progesterone) in vivo appeared to be more potent in the uterus than in the vagina.
Induction of short-term pseudopregnancy in gilts by the administration of estradiol benzoate or Estradiol dipropionate to achieve ovulatory synchronization for embryo collection
Anim Sci J 2021 Jan-Dec;92(1):e13480.PMID:33543586DOI:10.1111/asj.13480.
A study was conducted to investigate whether ovulation in gilts could be synchronized for embryo collection by the administration of estradiol benzoate (EB) or Estradiol dipropionate (EDP) to induce pseudopregnancy, followed by the treatment with prostaglandin F2α (PGF2α ) on 10 days after. Ten gilts each received a total of 20 mg of EB or EDP on Day 10 or EB on Day 10 and 14 to induce pseudopregnancy (Day 0 = onset of estrus). Donors received PGF2α 10 or 15 days (as a control) after the first administration of estrogens and subsequently eCG and hCG, and were then inseminated artificially. The embryos were collected 7 days after the administration of hCG, and assessed for embryo yield and their developmental stages. All protocols resulted in good embryo yield (9.8-13.2 embryos in average), and the embryos showed average ability to develop to the expanded blastocyst stage (3.29-4.03 as developmental scores) without any significant differences among the protocols. These results suggest that the administration of PGF2α 10 days after the treatment of gilts with EB or EDP would allow synchronization of ovulation and embryo collection, as well as shortening the period from estrus detection to embryo collection, thus improving embryo collection efficiency.
Estrus synchronization in microminipig using Estradiol dipropionate and prostaglandin F2α
J Reprod Dev 2016 Aug 25;62(4):373-8.PMID:27151362DOI:10.1262/jrd.2015-169.
The induction of pseudopregnancy by the exogenous administration of Estradiol dipropionate (EDP) was investigated in cyclic Microminipigs (MMpigs) and the effects of exogenous administration of prostaglandin (PG) F2α on estrus exhibition were assessed in pseudopregnant MMpigs. In experiment 1, ovariectomized MMpigs were given a single intramuscular injection of 0.5, 1.5, or 2.5 mg of EDP. The estradiol-17β level at each of these doses was significantly higher 1 to 3 days after EDP administration than on the day of the injection. In experiment 2, animals were given 1.5 mg of EDP once at 9 to 12 days after the end of estrus (D0) and then no (1.5 mg × 1 group), one (D0 and D4; 1.5 mg × 2 group), or two (D0, D4 and D7; 1.5 mg × 3 group) additional treatments. The pseudopregnancy rate was significantly higher in the 1.5 mg × 3 than in the 1.5 mg × 1 group. In experiment 3, PGF2α was administered twice between 26 and 28 days after EDP treatment to five pseudopregnant gilts with a 24-h interval between the two injections. Estrus after PGF2α treatment and LH surge were observed in 100% and 80% pseudopregnant MMpigs, respectively. The interval from the day of the first PGF2α treatment to the onset of estrus was 6.5 ± 0.2 days. These results indicate that multiple EDP treatments are required for induction of pseudopregnancy in MMpigs and estrus exhibition can be controlled in MMpigs by treatment with EDP and PGF2α.
