Abstract
Malathion serves as a pivotal pesticide in agriculture and the management of the Aedes aegypti mosquito. Despite its widespread use, there is a notable absence of studies elucidating the mechanisms through which malathion may affect the female reproductive system. Consequently, the objective of this investigation was to assess whether exposing juvenile female rats to low doses of malathion during the juvenile and peripubertal periods could compromise pubertal onset, estradiol levels, and the integrity of the ovaries and uterus while also examining the underlying mechanisms of damage. To achieve this, thirty juvenile female rats were subjected to either a vehicle or malathion (10 mg/kg or 50 mg/kg) between postnatal days 22 and 60, with subsequent verification of pubertal onset. Upon completion of the exposure period, blood samples were collected for estradiol assessment. The ovaries and uterus were then examined to evaluate histological integrity, oxidative stress, and the expression of genes associated with cell proliferation, antiapoptotic responses, and endocrine pathways. Although estradiol levels and pubertal onset remained unaffected, exposure to malathion compromised the integrity and morphometry of the ovaries and uterus. This was evidenced by altered oxidative profiles and changes in the expression of genes regulating the cell cycle, anti-apoptotic processes, and endocrine pathways. Our findings underscore the role of malathion in inducing cell proliferation, promoting cell survival, and causing oxidative damage to the female reproductive system in rats exposed during peripubertal periods.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116842. [PMID: 37356746 DOI: 10.1016/j.jep.2023.116842] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 06/19/2023] [Accepted: 06/22/2023] [Indexed: 06/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thespesia garckeana (F. Hoffm.) Exell & Hillc. is called Gorontula (Kola of Tula) in Nigeria, Morojwa in Bostwana, and Thespesia garckeana in South Africa and is widely distributed across Africa. Its parts reportedly possess multiple medicinal properties and are employed for treating various diseases. In Tula, Gombe State, Nigeria, the ripe fruit decoction is taken as remedy for female infertility as documented by Ochokwu and co in the Journal of Biology, Agriculture and Healthcare in 2015. AIM OF THE STUDY This research examined the effects of aqueous fruit extract of T. garckeana (F. Hoffm.) Exell & Hillc. (AFETG) on selected reproductive tissues and hormones in female rats and also evaluated the inhibitory potentials of its phytoconstituents against human 5-alpha reductase 2 (SRD5α2) using in silico approach. METHODS Twenty-five (25) sexually matured female rats were randomized into 5 groups (i.e. A - E). Oestrous in the rats was synchronized (subcutaneous oestradiol conjugate [10 μg/100 g BW]). Group A received distilled water (control). Group B received standard drug, clomiphene citrate (0.85 mg/kg BW), while groups C, D, and E received AFETG at 50, 100, and 200 mg/kg BW respectively. The animals were treated for five (5) days and sacrificed 24 h after. Their blood was collected and prepared for analysis of serum prolactin, oestradiol (E2), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) while ovaries, uteruses, and oviducts were studied for histological and histomorphometric changes. For the in silico study, the target protein, human steroid 5α-reductase 2 (SRD5α2) was prepared and its receptor grid was generated using Optimized Potential for Liquid Simulations-2005. The ligand 2D structures were prepared using LigPrep 2.4 software and docked using Glide. The binding energy of the ligands to the protein receptor was predicted using Molecular Mechanics/Generalized Born Surface Area (MM-GBSA) analysis. RESULTS AFETG significantly increased serum levels of E2 but did not alter serum levels of prolactin, LH and FSH when compared with distilled water and clomiphene citrate. AFETG also significantly increased ovarian tertiary follicular diameter, oviductal epithelial height and serosa thickness as well as uterine endometrial epithelial height, endometrial thickness, and myometrial thickness when compared with control. Ovarian secondary follicular diameter and oviductal submucosa thickness and muscular thickness were significantly decreased by AFETG when compared with control. Two compounds in T. garckeana (F. Hoffm.) Exell & Hillc.; D-Melezitose (-12.55 kcal/mol XP GScore) and 1, 3, 4-trihydroxy-5-oxo cyclohexane-1-carboxylic acid (-9.136 kcal/mol XP GScore) exhibited higher binding affinities for SRD5α2 than the reference ligand, epristeride (-8.096 kcal/mol XP GScore). In conclusion, the ability of AFETG to increase serum E2 level, thickness of uterine endometrium and ovarian tertiary follicles size can be explored for the treatment of female infertility caused by thinning of the uterine endometrium and reduced follicular size. Two compounds in AFETG (i.e. D-Melezitose and 1, 3, 4-trihydroxy-5-oxo cyclohexane-1-carboxylic acid are potential inhibitors of SRD5α2, thus aiding the biosynthesis of E2. Available evidence therefore corroborate the traditional use of T. garckeana (F. Hoffm.) Exell & Hillc fruit as a female fertility enhancer in Northern Nigeria.

The Phytochemical Profile and Biological Activity of Malva neglecta Wallr. in Surgically Induced Endometriosis Model in Rats. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27227869. [PMID: 36431970 PMCID: PMC9695446 DOI: 10.3390/molecules27227869] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 11/02/2022] [Accepted: 11/03/2022] [Indexed: 11/16/2022]
Abstract
Leaves and aerial parts of Malva neglecta Wallr. have been traditionally used in Anatolia for the treatment of pain, inflammation, hemorrhoids, renal stones, constipation, and infertility. This study investigated the effects of M. neglecta leaves in a rat endometriosis model. The dried plant material was extracted with n-hexane, ethyl acetate, and methanol, successively. Experimental endometriosis was surgically induced in six-week-old female, non-pregnant, Wistar albino rats by autotransplant of endometrial tissue to the abdominal wall. After twenty-eight days, rats were evaluated for a second laparotomy. Endometrial foci areas were assessed, and intraabdominal adhesions were scored. Rats were divided into five groups as control, n-hexane, ethyl acetate, methanol, and aqueous extracts, as well as reference. At the end of the treatment, all rats were sacrificed and endometriotic foci areas and intraabdominal adhesions were re-evaluated and compared with the previous findings. Moreover, peritoneal fluid was collected to detect tumor necrosis factor- α (TNF-α), vascular endothelial growth factor (VEGF), and interleukin-6 (IL-6) levels, and cDNA synthesis, and a quantitative real-time polymerase chain reaction (PCR) test was done. The phytochemical content of the most active extract was determined using High-Performance Liquid Chromatography (HPLC). Both endometrial volume and adhesion score decreased significantly in the group treated with methanol extract. In addition, significant decreases were observed in TNF-α, VEGF, and IL-6 levels in animals administered methanol extract. HPLC results showed that the activity caused by the methanol extract of M. neglecta was due to the polyphenols. Taken together, these novel findings indicate that M. neglecta may be a promising alternative for the treatment of endometriosis.

Abstract
Background The endometrium is a heterogeneous tissue composed of luminal epithelial (LE), glandular epithelial (GE), and stromal cells (ST), experiencing progesterone regulated dynamic changes during the estrous cycle. In the cow, this regulation at the transcriptomic level was only evaluated in the whole tissue. This study describes specific gene expression in the three types of cells isolated from endometrial biopsies following laser capture microdissection and the transcriptome changes induced by progesterone in GE and ST cells. Results Endometrial LE, GE, and ST cells show specific transcriptomic profiles. Most of the differentially expressed genes (DEGs) in response to progesterone are cell type-specific (96%). Genes involved in cell cycle and nuclear division are under-expressed in the presence of progesterone in GE, highlighting the anti-proliferative action of progesterone in epithelial cells. Elevated progesterone concentrations are also associated with the under-expression of estrogen receptor 1 (ESR1) in GE and oxytocin receptor (OXTR) in GE and ST cells. In ST cells, transcription factors such as SOX17 and FOXA2, known to regulate uterine epithelial-stromal cross-talk conveying to endometrial receptivity, are over-expressed under progesterone influence. Conclusions The results from this study show that progesterone regulates endometrial function in a cell type-specific way, which is independent of the expression of its main receptor PGR. These novel insights into uterine physiology present the cell compartment as the physiological unit rather than the whole tissue.

Abstract
Objective Endometriosis is a chronic debilitating inflammatory condition characterized by the presence of endometrial tissues outside the uterine cavity. Pelvic soreness and infertility are the usual association. Due to the poor effectiveness of the hormone therapy and the high incidence of recurrence following surgical excision, there is no single effective option for management of endometriosis. Mesenchymal stem cells (MSCs) are multipotent stromal cells studied for their broad immunoregulatory and anti-inflammatory properties; however, their efficiency in endometriosis cases is still a controversial issue. Our study aim was to evaluate whether adipose tissue-derived MSCs (AD-MSCs) could help with endometriosis through their studied anti-inflammatory role. Methods Female Wistar rats weighting 180 to 250 g were randomly divided into two groups: group 1, endometriosis group; established by transplanting autologous uterine tissue into rats’ peritoneal cavities and group 2, stem cell treated group; treated with AD-MSCs on the 5th day after induction of endometriosis. The proliferative activity of the endometriosis lesions was evaluated through Ki67 staining. Quantitative estimation of interferon γ, tumor necrosis factor-α, interleukin (IL)-6, IL-1β, IL-10, and transforming growth factor β expression, as well as immunohistochemical detection of CD68 positive macrophages, were used to assess the inflammatory status. Results The size and proliferative activity of endometriosis lesions were significantly reduced in the stem cell treated group. Stem cells efficiently mitigated endometriosis associated chronic inflammatory reactions estimated through reduction of CD68 positive macrophages and the expression of the proinflammatory cytokines. Conclusion Stem cell therapy can be considered a novel remedy in endometriosis possibly through its anti-inflammatory and antiproliferative properties.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a multifactorial hormonal disorder accompanied by impairment of endometrial function and structure. Pomegranate is recognized for its role in normalizing the female sex hormones in PCOS with little known about its effect on the accompanying endometrial histological alterations. AIM OF THE WORK To assess the possible ameliorative role of pomegranate juice extract (PJE) on endometrial injury in a rat model of PCOS. MATERIAL AND METHODS Forty adult albino rats were equally divided into 4 groups; control, PJE-treated (400mg/kg/day for 3 weeks), letrozole-treated (PCOS) (1mg/kg/day for 3 weeks), and PJE & PCOS groups. Serum Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), testosterone, estradiol, and tissue malondialdehyde (MDA) were assayed. Uterine samples were processed for histological staining with hematoxylin & eosin and Masson's trichrome stains, Ki67 and androgen receptor immunohistochemical staining, and scanning electron microscopy. RESULTS PCOS group revealed a significant increase in serum FSH, LH, testosterone, estradiol, and tissue MDA. Uterine sections depicted various histological alterations in the endometrium with signs of inflammation. A significant increase in the endometrial collagen fiber content, as well as a significant upregulation in Ki67 and androgen receptor immunohistochemical expression were detected. Scanning electron microscopy showed a significant decrease in the mean number of pinopodes. Concomitant administration of PJE efficiently restored the studied biochemical, histological, and immunohistochemical parameters. CONCLUSION PJE ameliorated PCOS accompanying endometrial histological alterations through its antioxidant, anti-inflammatory, anti-fibrotic, anti-proliferative, and anti-androgenic effects most probably due to its polyphenols content.

Abstract
Endometriosis causes infertility and the alterations in endometrial receptivity. Pinopodia in eutopic endometrial epithelium may have significant implications in the endometriosis-associated infertility. The aim of this study is to ascertain whether the surgical interventions to remove endometrioid ovarian cysts (EOCs) can improve endometrial receptivity. The study included 172 patients of reproductive age with EOC, who underwent laparoscopic cystectomy. Aspiration endometrial biopsy was performed at 6 and 12 months after the surgery during the proliferation and secretion phases. Histopathology analysis included H&E staining and IHC. Morphometric studies were performed on endometrial biopsies collected during the proliferation phase of 28 patients, and the secretion phase of 12 patients. The expression of IHC markers for estrogen receptors (ER) and progesterone receptors (PR) and the percentage of cells containing pinopodia were determined. A significant increase in the ER and PR expression was observed in the epithelium during the "middle stage, proliferation phase" and in the stroma and glands during "middle stage, secretion phase". A delay in endometrial secretory transformation and statistically significant decrease in the number of pinopodia was observed on the apical surface of the cells. These structural and functional alterations were observed both at 6 and 12 months after cystectomy. The endometriosis-associated infertility after surgical intervention of EOC could be due to the extensive expression of ER and PR during the proliferation and secretion phases, as well as the delayed secretory transformation and impaired formation of pinopodia in the eutopic endometrium in the patients at 6 and 12 months after surgery.

Abstract
Metabolic (Met) syndrome is characterized by hypertension, insulin resistance and dyslipidaemia with high risk of cardiovascular disease. Endoplasmic reticulum (ER) stress is a key contributor in the pathogenesis of Met syndrome. The current study investigates the effect of Tauroursodeoxycholate (TUDCA), an ER stress inhibitor, on Met syndrome-induced cardiovascular complications and the possible underlying signalling mechanisms. Met syndrome was induced in rats, which were then treated with TUDCA. Body weight, blood pressure, glucose tolerance and insulin tolerance tests were performed. ER stress, survival and oxidative stress markers were measured in heart and aorta tissue. The results showed that TUDCA improved metabolic parameters in rats with Met syndrome. Treatment mitigated the Met syndrome-induced cardiovascular complications through upregulating survival markers and downregulating ER and oxidative stress markers. These results highlight the protective effect of ER stress inhibition as a potential target in the management of cardiovascular complications associated with Met syndrome.

Abstract
Anthemis austriaca Jacq. flowers are traditionally used to alleviate abdominal pain, hemorrhoids, ovary diseases and pneumonia. This study aimed to investigate the effects of A. austriaca flowers, which are frequently used in gynecological disorders, on the rat endometriosis model. The rat endometriosis model was used to evaluate the potential activity of the plant in endometriosis. The dried plant material was extracted with n-hexane, ethyl acetate (EtOAc), and methanol (MeOH), successively. The obtained extracts from A. austriaca flowers were applied to the rats. The adhesion scores, endometrial foci areas, and cytokine levels of the peritoneal fluids were measured on surgical induction of endometriosis in rats. The adhesion scores, endometriotic volume, and cytokine levels of the peritoneal fluids were reduced in the EtOAc, MeOH, and buserelin acetate-treated (reference) groups. The MeOH extract reduced the adhesion scores and endometrial foci areas from 3.1 to 1.1 (p < 0.01) and from 86.4 to 40.5 (p < 0.01), respectively and also the MeOH extract reduced tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), and interleukin (IL)-6 levels of the peritoneal fluids from 13.7 to 3.8 (p < 0.01), from 28.4 to 16.3 (p < 0.05) and from 50.2 to 24.3 (p < 0.01), respectively. Therefore, isolation studies were conducted on the EtOAc and MeOH extracts. After the MeOH extract was fractionated using RP-18 column, the obtained subfractions were evaluated again on the endometriosis rat model. Subfractions A and C of the MeOH extract displayed statistically significant activity on the endometriosis rat model. Phytochemical investigation resulted in the isolation of 4-β-D-glucopyranosyloxy-6-methyl-2H-pyran-2-one (1) from Fr. A and quercetin (2), apigenin-7-O-(3″-O-acetyl)-β-D-glucopyranoside (3), apigenin-7-O-(6″-O-acetyl)-β-D-glucopyranoside (4), apigenin-7-O-β-D-glucopyranoside (5), quercetin-7-O-β-D-glucopyranoside (6) from Fr. C. Moreover, β-sitosterol-3-O-β-D-glucopyranoside (7) was isolated from the EtOAc extract. As a conclusion, the MeOH extract obtained from A. austriaca flowers contributed to the regression of endometriosis. In addition, flavonoids and sterols of the plant were detected as the possible compounds responsible for the activity.
