Protective effect of Salvia hispanica (chia seeds) against obesity induced ovarian disorders in rat model. Tissue Cell 2023; 83:102156. [PMID: 37437332 DOI: 10.1016/j.tice.2023.102156] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 06/19/2023] [Accepted: 07/03/2023] [Indexed: 07/14/2023]
Abstract
The main goal of the current report is to assess the protective impacts of chia seeds against obesity-induced ovarian dysfunctions with a trial to elucidate the mechanism of action. Forty rats were divided into 4 groups including lean untreated, lean consuming chia seeds, obese untreated, and rats consumed high-fat diet (HFD) mixed with ground chia seeds for 10 weeks. Anthropometric measures including visceral fat, peri-ovarian fat, ovarian weights, and duration of the estrous cycle were computed. Serum luteinizing (LH), follicular stimulating (FSH), progesterone, estradiol hormones, and tumor necrosis-α (TNF-α) were estimated. Ovarian histopathology and immunohistochemistry (CD31) were performed. Results showed that chia seeds clearly reduced obesity and induced alteration in anthropometric measures with a clear increase in LH and progesterone. Such seeds notably reversed histopathological alteration and reduced TNF-α, and CD31 induced by HFD. Conclusively, chia seeds have a potential protective role against obesity-induced ovarian dysfunction owing to their anti-inflammatory properties.

Notch Signaling Induced by Endoplasmic Reticulum Stress Regulates Cumulus-Oocyte Complex Expansion in Polycystic Ovary Syndrome. Biomolecules 2022; 12:biom12081037. [PMID: 36008931 PMCID: PMC9405998 DOI: 10.3390/biom12081037] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/16/2022] [Accepted: 07/25/2022] [Indexed: 12/10/2022] Open
Abstract
Endoplasmic reticulum (ER) stress activated in granulosa cells contributes to the pathophysiology of polycystic ovary syndrome (PCOS). In addition, recent studies have demonstrated that Notch signaling plays multiple roles in the ovary via cell-to-cell interactions. We hypothesized that ER stress activated in granulosa cells of antral follicles in PCOS induces Notch signaling in these cells, and that activated Notch signaling induces aberrant cumulus-oocyte complex (COC) expansion. Expression of Notch2 and Notch-target transcription factors was increased in granulosa cells of PCOS patients and model mice. ER stress increased expression of Notch2 and Notch-target transcription factors in cultured human granulosa-lutein cells (GLCs). Inhibition of Notch signaling abrogated ER stress-induced expression of genes associated with COC expansion in cultured human GLCs, as well as ER stress-enhanced expansion of cumulus cells in cultured murine COCs. Furthermore, inhibition of Notch signaling reduced the areas of COCs in PCOS model mice with activated ER stress in the ovary, indicating that Notch signaling regulates COC expansion in vivo. Our findings suggest that Notch2 signaling is activated in granulosa cells in PCOS and regulates COC expansion. It remains to be elucidated whether aberrant COC expansion induced by the ER stress-Notch pathway is associated with ovulatory dysfunction in PCOS patients.

Abstract
Polycystic ovary syndrome (PCOS) is related to low levels of serum l-carnitine, which has antioxidant, anti-inflammatory and antiapoptotic properties. The aim of this study was to investigate the effect of l-carnitine on folliculogenesis in mice following induction of PCOS. PCOS was induced by daily injections of testosterone enanthate (1mg per 100g, s.c., for 35 days). NMRI mice (21 days old) were divided into four groups (n=6 per group): Control, Control+l-carnitine, PCOS and PCOS+l-carnitine. Mice were treated with 500mgkg-1, i.p., l-carnitine every second day for 28 days. Ovaries were studied stereologically and serum concentrations of FSH, LH, testosterone, interleukin (IL)-6 and tumour necrosis factor (TNF)-α were determined using ELISA kits. Serum concentrations of malondialdehyde (MDA) and the ferric ion reducing antioxidant power (FRAP) were also analysed. Apoptosis of follicles was evaluated by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling (TUNEL). CD31 was assessed immunohistochemically. Data were analysed using one-way analysis of variance (ANOVA) and Tukey's test, differences considered significant at P<0.05.The total volume of the ovary, cortex volume, oocyte volume, zona pellucida thickness and the number of antral follicles increased significantly, whereas the number of primary and preantral follicles decreased significantly, in the PCOS+l-carnitine versus PCOS group. In the PCOS+l-carnitine group, serum concentrations of FSH and FRAP increased significantly, whereas there were significant decreases in serum concentrations of testosterone, LH, MDA, IL-6 and TNF-α, as well as in the percentage of TUNEL-positive apoptotic cells, compared with the PCOS group. l-Carnitine improves folliculogenesis and is therefore suggested as a therapeutic supplement in the treatment of PCOS.

Abstract
BACKGROUND AND OBJECTIVES Polycystic ovary syndrome (PCOS) is a common heterogeneous endocrinological and metabolic disorder in women of reproductive age which leads to infertility/subfertility. The present study was commenced to elucidate the therapeutic efficacy of melatonin in the pathogenesis of letrozole induced polycystic ovary syndrome (PCOS) in Wistar rat. MATERIALS AND METHODS Letrozole was administered orally (1 mg kg-1) to induce PCOS condition in Wistar female rats for a period of 2-3 weeks followed by a dose of melatonin (200 µg/100 g b.wt.) to PCOS induced rats. On the completion of experimental period the level of cytokines and expression level of different receptors was assessed. RESULTS The PCOs rats showed down regulation in melatonin (MT1 and MT2), estrogen (ER-α) and cytokine (IL-2R and IL-6R) receptors expression and high circulatory level of IL-6 and TNF-α during PCO condition. These anomalies in expression pattern and circulatory level of cytokines were restored following the treatment. CONCLUSION Finding of present study showed the role of melatonin supplementation at receptor level and also suggesting a crosstalk between MT1R / MT2R via cytokine IL-2R and IL-6R resulting in modulation of ER-α receptors.

Abstract
The Notch signaling pathway, known to be a highly conserved signaling pathway in embryonic development and adult tissue homeostasis, participates in cell fate decisions that include cellular differentiation, cell survival and cell death. However, other studies have shown that aberrant in Notch signaling is pro-tumorigenic, particularly in hepatocellular carcinoma (HCC). HCC is one of the most common malignant tumors in the world and has a high mortality rate. Growing evidence supports that Notch signaling plays a critical role in the development of HCC by regulating the tumor microenvironment, tumorigenesis, progression, angiogenesis, invasion and metastasis. Accordingly, overexpression of Notch is closely associated with poor prognosis in HCC. In this review, we focus on the pro-tumorigenic role of Notch signaling in HCC, summarize the current knowledge of Notch signaling and its role in HCC development, and outline the therapeutic potential of targeting Notch signaling in HCC.

Abstract
BACKGROUND Many studies have reported that inflammation and oxidative stress are involved in the pathogenesis of polycystic ovary syndrome (PCOS). Bone marrow mesenchymal stromal cells (BM-MSCs) have anti-oxidant and anti-inflammation properties. In this study, we investigate the beneficial effect of stem cell therapy on folliculogenesis in mice with induced PCOS METHODS: Mouse model of PCOS was performed through daily injection of testosterone enanthate (1 mg/100 g/body weight subcutaneous (s.c).) for a period of 5 weeks. Naval Medical Research Institute (NMRI) mice (21 days old) were divided into three groups: control, PCOS and PCOS + BM-MSCs. BM-MSCs were labeled with Hoechst 33342 (0.5 µg/mL) and then injected into the mice (106/animal, via the tail vein) at 1 and 14 days after PCOS confirmation. Mice were humanely killed at 2 weeks after last transplantation. Ovarian stereological studies were done. Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), testosterone, interleukin (IL)-6 and tumor necrosis factor (TNF)-α serum levels were measured. The levels of malondialdehyde (MDA) and total antioxidant capacity (TAC) in serum were analyzed. Apoptotic index for ovarian follicles was assessed using Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL). CD31 expression in ovarian vessels was assessed with the immunohistochemistry. RESULTS There was a significant increase in the total volume of ovary, cortex, number of antral follicles, volume of oocyte and zona pellucida thickness, and there was a significant decrease in the primary and preantral follicles number in the PCOS + BM-MSCs group compared with the PCOS group. There was a significant increase in the serum level of FSH and TAC and a significant decrease in the serum level of testosterone, LH, MDA and percentage of TUNEL-positive apoptotic cells in the PCOS + BM-MSCs group in comparison with the PCOS group. DISCUSSION BM-MSC transplantation improves folliculogenesis in mice with induced PCOS. BM-MSC therapy can be an operative treatment for PCOS via anti-inflammatory, anti-oxidant and anti-apoptotic properties.

Abstract
We have studied the ontogeny of the developing human male and female urogenital tracts from 9 weeks (indifferent stage) to 16 weeks (advanced sex differentiation) of gestation by immunohistochemistry on mid-sagittal sections. Sixteen human fetal pelvises were serial sectioned in the sagittal plane and stained with antibodies to epithelial, muscle, nerve, proliferation and hormone receptor markers. Key findings are: (1) The corpus cavernosum in males and females extends into the glans penis and clitoris, respectively, during the ambisexual stage (9 weeks) and thus appears to be an androgen-independent event. (2) The entire human male (and female) urethra is endodermal in origin based on the presence of FOXA1, KRT 7, uroplakin, and the absence of KRT10 staining. The endoderm of the urethra interfaces with ectodermal epidermis at the site of the urethral meatus. (3) The surface epithelium of the verumontanum is endodermal in origin (FOXA1-positive) with a possible contribution of Pax2-positive epithelial cells implying additional input from the Wolffian duct epithelium. (4) Prostatic ducts arise from the endodermal (FOXA1-positive) urogenital sinus epithelium near the verumontanum. (5) Immunohistochemical staining of mid-sagittal and para-sagittal sections revealed the external anal sphincter, levator ani, bulbospongiosus muscle and the anatomic relationships between these developing skeletal muscles and organs of the male and female reproductive tracts. Future studies of normal human developmental anatomy will lay the foundation for understanding congenital anomalies of the lower urogenital tract.

Abstract
Livistona chinensis seeds have been used for centuries to clinically treat various types of cancer. Our published data suggest that Livistona chinensis seeds are able to inhibit hepatocellular carcinoma (HCC) growth in vitro and in vivo via promotion of mitochondrial-dependent apoptosis. To further elucidate the molecular mechanisms of its antitumor activity, in the present study, we used an HCC xenograft mouse model to evaluate the effect of an ethanol extract of Livistona chinensis seeds (EELC) on tumor angiogenesis and on the activation of the Notch pathway. Intratumoral microvessel density (MVD) in HCC xenograft mouse tumors was evaluated via immunohistochemical (IHC) staining for CD31. The mRNA and protein expression of vascular endothelial growth factor A (VEGF-A), VEGFR-2, Notch, Dll4 and Jagged1 was evaluated using RT-PCR and IHC, respectively. We found that EELC profoundly reduced MVD in the HCC mouse tumors, demonstrating the in vivo inhibitory effect of EELC on tumor angiogenesis. In addition, EELC treatment reduced the expression of VEGF-A and VEGFR-2 in tumor tissues. Furthermore, EELC treatment inhibited the expression of Notch, Dll4 and Jagged1. Our findings suggest that Livistona chinensis seeds inhibit tumor angiogenesis through suppression of the Notch pathway.
