Can some food/medicinal plants directly affect porcine ovarian granulosa cells and mitigate the toxic effect of toluene?

The action of buckwheat, rooibos and vitex on healthy female reproductive systems, as well as their ability to mitigate the reproductive toxicity of environmental contaminant toluene have not yet been examined. We analysed the influence of toluene (0, 10, 100 or 1000 ng/mL) with and without these plant extracts (10 μg/mL) on cultured porcine ovarian granulosa cells. Cell viability, proliferation (PCNA accumulation), apoptosis (accumulation of bax) and release of progesterone (P) and oestradiol (E) were measured.

Ghrelin and obestatin can promote human ovarian granulosa cell functions and FSH effects.

The aim of the present in-vitro experiments was to examine the direct influence of ghrelin and obestatin on viability, proliferation and progesterone release by human ovarian granulosa cells and their response to FSH administration. Human granulosa cells were cultured in presence of ghrelin or obestatin (both at 0, 1, 10 or 100 ng/ml) alone or in the presence of FSH (10 ng/ml). Cell viability, accumulation of proliferation markers PCNA and cyclin B1 and release of progesterone were analyzed by Trypan blue extrusion test, quantitative immunocytochemistry and ELISA.

Can flaxseed, chia or puncture vine affect mare ovarian cell functions and prevent the toxic effect of the environmental contaminant toluene?

The aim of this in vitro study was to examine the potential effect of functional food plant extracts, namely, extracts of flaxseed (Linum usitatissimum L.), chia (Salvia hispanica) and puncture vine (Tribulus terrestris L.), on basic mare ovarian cell functions and their response to the environmental contaminant toluene.

Chia (Salvia hispanica L.) can directly suppress basic ovarian cell functions in two farm animal species and protect ovarian cells from the proliferation-stimulating influence of xylene.

The influence of the functional food plant chia (Salvia hispanica L.) on reproduction functions and its ability to prevent the negative effects of environmental contaminants has not yet been studied. Our study aimed to examine the effect of chia seed extract alone and in combination with xylene on the markers of proliferation, apoptosis and hormones release by cultured bovine and porcine ovarian granulosa cells.

Ginkgo, fennel, and flaxseed can affect hormone release by porcine ovarian cells and modulate the effect of toluene.

Experimental studies have documented the toxic effects of toluene on the mammalian female reproductive processes. The aim of this in vitro study was to examine the potential of functional food plant extracts, namely, of ginkgo, fennel, and flaxseed, in modifying the toluene-induced effects on ovarian hormone release. Porcine granulosa cells were incubated with ginkgo, fennel, or flaxseed extracts (0, 1, 10, or 100 µg/mL) and/or toluene (10 µg/mL).

Bee pollens originating from different species have unique effects on ovarian cell functions.

Context: The species-specific differences and mechanisms of action of bee pollen on reproduction have not been well studied.

Objective: We compared the effects of bee pollen extracts from different plants on ovarian cell functions.

Materials And Methods: We compared the effects of pollens from black alder, dandelion, maize, rapeseed, and willow at 0, 0.

Plant polyphenols can directly affect ovarian cell functions and modify toluene effects.

The influence of toluene alone and in combination with plant polyphenols apigenin, daidzein or rutin on viability, proliferation (proliferating cell nuclear antigen accumulation), apoptosis (Bax accumulation) and release of progesterone (P), testosterone (T) and estradiol (E) in cultured porcine ovarian granulosa cells was evaluated. Toluene reduced ovarian cell viability, proliferation and E release; it promoted P release, demonstrating no effect on apoptosis or T output. Apigenin alone failed to affect cell viability, proliferation, apoptosis and P and T release, but stimulated E release, promoting the inhibitory action of toluene on proliferation, preventing and even reversing the stimulatory effect of toluene on apoptosis and P.

Buckwheat, rooibos, and vitex extracts can mitigate adverse effects of xylene on ovarian cells in vitro.

This study examines whether selected functional food and medicinal plants can mitigate the adverse effects of xylene on ovarian cells. The influences of xylene (0, 10, 100, or 1000 ng/mL), buckwheat (Fagopyrum esculentum), rooibos (Aspalathus linearis), vitex (Vitex agnus-castus), extracts (10 μg/mL each), and a combination of xylene with these plant additives on cultured porcine ovarian granulosa cells are compared. Cell viability, proliferation (PCNA accumulation), apoptosis (accumulation of bax), and release of progesterone (P4) and estradiol (E2) were analyzed by the trypan blue tests, quantitative immunocytochemistry, and enzyme-linked immunosorbent assays, respectively.

Abatement of the Stimulatory Effect of Copper Nanoparticles Supported on Titania on Ovarian Cell Functions by Some Plants and Phytochemicals.

The application of nanoparticles has experienced a vertiginous growth, but their interaction with food and medicinal plants in organisms, especially in the control of reproduction, remains unresolved. We examined the influence of copper nanoparticles supported on titania (CuNPs/TiO), plant extracts (buckwheat () and vitex ()), phytochemicals (rutin and apigenin), and their combination with CuNPs/TiO on ovarian cell functions, using cultured porcine ovarian granulosa cells. Cell viability, proliferation (PCNA accumulation), apoptosis (accumulation of bax), and hormones release (progesterone, testosterone, and 17-estradiol) were analyzed by the Trypan blue test, quantitative immunocytochemistry, and ELISA, respectively.

Effects of benzene on gilts ovarian cell functions alone and in combination with buckwheat, rooibos, and vitex.

We aimed to examine the influence of benzene and of three dimethyl sulfoxide (DMSO) plant extracts-buckwheat (Fagopyrum Esculentum), rooibos (Aspalathus linearis), and vitex, (Vitex Agnus-Castus), and the combination of benzene with these three plant extracts on basic ovarian cell functions. Specifically, the study investigated the influence of benzene (0, 10, 100, or 1000 ng/mL) with and without these three plant additives on porcine ovarian granulosa cells cultured during 2 days with and without these additives. Cell viability, proliferation (accumulation of proliferating cell nuclear antigen, PCNA), apoptosis (accumulation of Bcl-2-associated X protein , bax), and the release of progesterone (P) and estradiol (E) were analyzed by the Trypan blue test, quantitative immunocytochemistry, and enzyme-linked immunosorbent assay, respectively.

Plant isoflavones can prevent adverse effects of benzene on porcine ovarian activity: an in vitro study.

We evaluated the influence of the oil-related environmental contaminant benzene (0, 10, 100, or 1000 ng/mL) alone and in combination with apigenin, daidzein, or rutin (10 μg/mL each) on viability; proliferation (accumulation of proliferating cell nuclear antigen); apoptosis (accumulation of Bax); and release of progesterone (P), testosterone (T), and estradiol (E) in cultured porcine ovarian granulosa cells. Cell viability; proliferation; apoptosis; and release of P, T, and E have been analyzed by the trypan blue test, quantitative immunocytochemistry, and ELISA, respectively. Benzene did not affect apoptosis, but reduced ovarian cell viability and P and E release, and promoted proliferation and T output.

Effect of morphology and support of copper nanoparticles on basic ovarian granulosa cell functions.

The aim of this survey is to explore the possible effects of unsupported and supported copper nanoparticles (CuNPs) of different morphologies on basic ovarian cell functions. For this purpose, we have compared the activity of unsupported spherical, triangular, and hexagonal CuNPs, as well as of spherical CuNPs supported on titania, zeolite Y and activated charcoal (0, 1, 10, or 100 ng/mL) on cultured porcine ovarian granulosa cells. Cell viability, proliferation (accumulation of proliferating cell nuclear antigen, PCNA), apoptosis (accumulation of Bcl-2-associated X protein, bax) and release of steroid hormones progesterone, testosterone, and 17-estradiol have been analyzed by the Trypan blue test, quantitative immunocytochemistry, and ELISA, respectively.

Interrelationships between metabolic hormones, leptin and ghrelin, and oil-related contaminants in control of oxytocin and prostaglandin F release by feline ovaries.

We examined the effects of metabolic hormones leptin and ghrelin, and the oil-related environmental contaminants toluene and xylene on the release of ovarian hormones by gravid and non-gravid cats, as well as the functional interrelationships between metabolic hormones and contaminants. Ovarian fragments of non-gravid cats were cultured with and without leptin and toluene. Next, ovarian fragments of either non-gravid or gravid animals were cultured with and without ghrelin and xylene.

Effects of benzene, quercetin, and their combination on porcine ovarian cell proliferation, apoptosis, and hormone release.

We hypothesized that the environmental contaminant benzene and the plant antioxidant quercetin may affect ovarian cell functions and that quercetin could offer protection against the adverse effects of benzene. This study aimed to examine the action of benzene, quercetin, and their combination on porcine ovarian granulosa cell functions. We elucidated the effects of benzene (20  g mL ), quercetin (at the doses 0, 1, 10, 100  g mL ), and their combination on ovarian granulosa cell functions (proliferation, apoptosis, and hormone release) in vitro using immunocytochemistry and enzyme immunoassay respectively.

Can xylene and quercetin directly affect basic ovarian cell functions?

Exposure to xylene leads to dysfunction of mammalian female reproduction. Quercetin present in vegetables contribute significantly to their role as health-promoting foods. The effects of xylene and quercetin on ovarian cell function, their interrelationships, and mechanisms of action are insufficiently studied.
