Effects of Aloe vera extract on growth, viability, ultrastructure and expression of mRNA for antioxidant enzymes in bovine secondary follicles cultured in vitro. Anim Reprod Sci 2022; 247:107078. [PMID: 36179655 DOI: 10.1016/j.anireprosci.2022.107078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 07/01/2022] [Accepted: 09/21/2022] [Indexed: 11/24/2022]
Abstract
This study aimed to investigate the effects of Aloe vera extract on follicular growth, viability, ultrastructure, and mRNA levels for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase 1 (GPX1) and peroxiredoxin 6 (PRDX6) in bovine secondary follicles cultured in vitro. To this end, secondary follicles were mechanically isolated from the ovarian cortex and cultured at 38.5 °C, with 5% CO2 in air, for 18 days in TCM-199+ alone or supplemented with 2.5%, 5.0%, 10.0% and 20.0% Aloe vera extract. Follicular growth, morphology and antrum formation were evaluated every 6 days, while ultrastructure was evaluated at the end of culture. Analysis of viability was performed by calcein-AM and ethidium homodimer-1, while mRNA levels for SOD, CAT, GPX1 and PRDX6 were evaluated by real-time PCR at the end of culture. The results show that follicles cultured with 2.5% Aloe vera had increased the rate of antrum formation, while 2.5% and 5.0% Aloe vera improved follicular viability rate. Follicles cultured with 2.5% and 10.0% Aloe vera increased the levels of mRNA for SOD and GPX1 respectively, but the levels of CAT were reduced in follicles cultured with 2.5%, 5.0%, 10.0% and 20.0%. Additionally, follicles cultured with 2.5% of Aloe vera had their ultrastructure well preserved, while those cultured with 5.0%, 10.0% and 20.0% exhibited increased oocyte vacuolization and damaged organelles. In conclusion, 2.5% Aloe vera increases antrum formation, viability and expression of mRNA for SOD in cultured secondary follicles, but higher concentrations of Aloe vera have negative effects on follicular ultrastructure.

Aloe vera increases mRNA expression of antioxidant enzymes in cryopreserved bovine ovarian tissue and promotes follicular growth and survival after in vitro culture. Cryobiology 2021; 102:104-113. [PMID: 34270982 DOI: 10.1016/j.cryobiol.2021.07.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 07/10/2021] [Indexed: 11/25/2022]
Abstract
The aims of the present study were to evaluate the effects of Aloe vera extract on expression of mRNA for antioxidant enzymes in bovine ovarian tissue after vitrification, as well as on follicular morphology, viability, activation and extracellular matrix in cultured ovarian tissues that had been previously vitrified. Fragments from bovine ovarian cortical tissue were cryopreserved in a vitrification solution alone or supplemented with two concentrations of Aloe vera (10 or 50%). After thawing, the cryopreserved tissues were analyzed by histological techniques, as well as the levels of mRNA for SOD, CAT, PRDX6 and GPX1 were investigated. Furthermore, cryopreserved fragments were then culture in vitro in α-MEM for 6 days. Histological evaluation of cultured tissues was performed to determine the percentages of normal and developing follicles. The results showed that, after vitrification, the presence of Aloe vera in both concentrations was able to maintain percentages of collagen fibers similar to fresh tissues (P < 0.05). Aloe vera in both concentrations significantly increased mRNA levels for PRDX6 and GPX1 in cryopreserved tissues, while 10% Aloe vera increased mRNA levels for SOD (P < 0.05). In parallel, after in vitro culture, fragments vitrified in the presence of 10% Aloe vera had significantly higher levels of morphologically healthy follicles when compared to tissue that were vitrified without Aloe vera. In fragments vitrified with Aloe vera, the rate of developing follicles was significantly higher than in tissues vitrified without Aloe vera. Tissues vitrified with 10% Aloe vera and cultured in vitro maintained percentages of collagen fibers similar to fresh tissues. In conclusion, 10% Aloe vera increases the expression of mRNA for PRDX6, GPX1 and SOD in vitrified ovarian tissues, maintains follicular survival and promotes activation and development of follicles after in vitro culture of vitrified bovine ovarian tissue.

Growth differentiation factor-9 improves development, mitochondrial activity and meiotic resumption of sheep oocytes after in vitro culture of secondary follicles. Reprod Domest Anim 2019; 54:1169-1176. [PMID: 31173652 DOI: 10.1111/rda.13485] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Accepted: 06/04/2019] [Indexed: 01/03/2023]
Abstract
This study analysed the effect of growth differentiation factor-9 (GDF-9) on the in vitro culture of isolated ovine secondary follicles. The follicles were cultured in α-MEM supplemented with BSA, insulin, glutamine, hypoxanthine, transferrin, selenium, ascorbic acid and FSH (α-MEM+ -control medium) or α-MEM+ supplemented with 1, 10, 50 or 100 ng/ml GDF-9. Next, the oocytes were destined to in vitro maturation (IVM). After 12 days of culture, there were no differences regarding the percentage of normal follicles, antrum formation and follicle diameter between the treatments (p > 0.05). The rates of fully grown oocytes (≥110 µm) were higher (p < 0.05) in 100 ng/ml GDF-9 than other treatments, except for 10 ng/ml of GDF-9 (p > 0.05). Treatment containing 100 ng/ml GDF-9 showed higher (p < 0.05) mitochondrial activity than the control group. Moreover, 100 ng/ml GDF-9 showed more oocytes in MI than α-MEM+ , 1 or 50 ng/ml GDF-9 (p < 0.05). In conclusion, 100 ng/ml GDF-9 increased the growth, mitochondrial function and meiotic resumption of oocytes from in vitro grown sheep secondary follicles.

Pharmacological Properties of Morus nigra L. (Black Mulberry) as A Promising Nutraceutical Resource. Nutrients 2019; 11:nu11020437. [PMID: 30791521 PMCID: PMC6412198 DOI: 10.3390/nu11020437] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 02/13/2019] [Accepted: 02/18/2019] [Indexed: 12/27/2022] Open
Abstract
Mulberry plants belonging to the Moraceae family have been grown for the purpose of being the nutrient source for silk worm and raw materials for the preparation of jams, marmalades, vinegars, juices, wines, and cosmetics. Morus nigra L. (black mulberry) is native to Southwestern Asia, and it has been used as a traditional herbal medicine for animals and humans. In this article, recent research progress on various biological and pharmacological properties of extracts, fractions, and isolated active constituents from different parts of M. nigra are reviewed. M. nigra exhibited a wide-spectrum of biological and pharmacological therapeutic effects including antinociceptive, anti-inflammatory, antimicrobial, anti-melanogenic, antidiabetic, anti-obesity, anti-hyperlipidemic, and anticancer activities. M. nigra also showed protective effects against various human organs and systems, mainly based on its antioxidant capacity. These findings strongly suggest that M. nigra can be used as a promising nutraceutical resource to control and prevent various chronic diseases.
