Molecular regulation of progesterone synthesis in the bovine corpus luteum

Veterinární Medicína, 2007
In bovine luteal cells, progesterone can directly affect its own synthesis by increasing the activity of 3β-HSD. The effect of progesterone on its own secretion coincides with increased expression of the genes for 3β-HSD, StAR, and cytochrome P450scc ...

Chrysin Mitigates Acetamiprid‐Induced Testicular Injury in Mice via Suppression of Endoplasmic Reticulum Stress and Inflammation

Environmental Toxicology, EarlyView.
ABSTRACT Acetamiprid (ACP) is a neonicotinoid pesticide that is extensively utilized for the management of insect populations, but its toxic effects on the male reproductive system have become a source of concern. Chrysin (CHR) is a natural flavone found in many plants and bee products, including honey and propolis.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Regulatory mechanism of Cordyceps sinensis mycelium on mouse Leydig cell steroidogenesis

, 2012
[[abstract]]We demonstrate the mechanism by which Cordyceps sinensis (CS) mycelium regulates Leydig cell steroidogenesis. Mouse Leydig cells were treated with forskolin, H89, phorbol 12-myristate 13-acetate, staurosporine, or steroidogenic enzyme ...

Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

Filamin A in the ovary: a mediator of granulosa cell functions

Reproduction and Fertility
Filamin A (FLNA) regulates the mechanical properties and shape of cells by cross-linking actin filaments orthogonally. It also serves as a scaffold for numerous interacting proteins, thereby coordinating cell differentiation and morphogenesis.

Cordyceps sinensis mycelium activates PKA and PKC signal pathways to stimulate steroidogenesis in MA-10 mouse Leydig tumor cells

, 2012
[[abstract]]Cordyceps sinensis (CS) mycelium stimulates steroidogenesis in MA-10 mouse Leydig tumor cells, but the mechanisms remain unclear. In this study, MA-10 cells were treated with different reagents in the presence or absence of CS (10 mg/ml) for ...

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...
