Abstract:
Infertility is believed to be triggered by endometriosis whose pathophysiology and the etiology is still unknown. Certain genes play pivotal roles in pathogenesis of endometriosis. Natural products and plants are used as important sources for production of new drugs. The current study assesses the effects of gamma-oryzanol (GO) in a rat model with surgically induced endometriosis. The experimental endometriosis was induced in 24 wistar rats, and the animals were subsequently subdivided into endometriosis-sole (endom group), 3000 and 6000 µg/kg GO (GO-3000 and GO-6000) and Vit C groups. The protein levels of estrogen receptor-alpha (ER-α), Steroidogenic factor 1 (SF1), Sirtuin 1 (SIRT1), heme oxygenase 1 (HO1), light chain 3 (LC3B) and Beclin1 (BECN1) were assessed. TUNEL staining was used for detecting the apoptosis rate. The results revealed that protein levels of SF1, HO1, and total LC3B significantly (P < 0.05) decreased in GO-6000-treated groups compared to endom group. Moreover, the protein level of BECN1 and SIRT-1 significantly (P < 0.05) increased in GO-6000-treated groups compared to endom group. GO treatment did not imply any significant difference (P > 0.05) concerning the protein levels of ER-α. The TUNEL staining results showed higher TUNEL-positive cells reactions in the rats treated with GO-6000 and Vit C. Thus, GO is involved in improving condition rats involved with endometriosis through modulation in the protein levels of some molecules and also induction of apoptosis.
Insights
Gamma-oryzanol (GO) shows promise in improving endometriosis conditions in rats. GO treatment modulated key protein levels and induced apoptosis, suggesting a potential therapeutic role for this natural compound.
Area of Science:
- Reproductive Biology
- Molecular Biology
- Pharmacology
Background:
- Endometriosis is a complex condition linked to infertility with unknown causes.
- Genetic factors are crucial in endometriosis development.
- Natural products offer potential for novel drug discovery.
Purpose of the Study:
- To investigate the therapeutic effects of gamma-oryzanol (GO) on surgically induced endometriosis in a rat model.
- To assess GO's impact on specific protein expressions and apoptosis rates in endometriosis.
Main Methods:
- Surgically induced endometriosis in 24 Wistar rats.
- Treatment groups: endometriosis-sole, gamma-oryzanol (3000 & 6000 µg/kg), and Vitamin C.
- Assessed protein levels (ER-α, SF1, SIRT1, HO1, LC3B, BECN1) and apoptosis via TUNEL staining.
Main Results:
- GO (6000 µg/kg) significantly decreased SF1, HO1, and LC3B protein levels.
- GO (6000 µg/kg) significantly increased BECN1 and SIRT1 protein levels.
- GO and Vitamin C treatments increased TUNEL-positive cells, indicating apoptosis induction.
Conclusions:
- Gamma-oryzanol demonstrates a therapeutic effect in an endometriosis rat model.
- GO modulates specific molecular pathways and induces apoptosis in endometriosis.
- Further research into GO as a natural therapeutic agent for endometriosis is warranted.
