Bisphenol A exposure stimulates prostatic fibrosis via exosome-triggered epithelium changes.

Fibrosis is the pathological basis for the clinical progression of benign prostatic hyperplasia (BPH). Prostatic fibrosis is an important risk factor in patients with BPH who experience lower urinary tract symptoms. Bisphenol A (BPA) is an environmental endocrine disruptor (EED) that causes prostate defects.

Mediation of PM2.5-induced cytotoxicity: the role of P2X7 receptor in NR8383 cells.

Ambient fine particulate matter (PM2.5) is a threat to public health. The P2 X 7purinergic receptor (P2X7R) is a modulator that responds to inflammation.

Circ_0027470 promotes cadmium exposure-induced prostatic fibrosis via sponging miRNA-1236-3p and stimulating SHH signaling pathway.

Cadmium (Cd) is a toxic heavy metal pollutant and serves as an important environmental endocrine-disrupting chemical. Cd exposure is believed to can enhance the risks of age-related disorders including benign prostatic hyperplasia (BPH). This study was to investigate the harms of Cd exposure on mice prostate and human nonmalignant prostate epithelial RWPE-1 cells.

Alcohol Exposure Induces Depressive and Anxiety-like Behaviors via Activating Ferroptosis in Mice.

Alcohol use disorder (AUD) is a global public health problem and is frequently comorbid with mental disorders, including anxiety and depression. Ferroptosis is an iron-dependent cell death, which is involved in the pathological process of various diseases such as neurodegenerative diseases, but the role of ferroptosis in the mediation of AUD and its induced mental disorders is unclear. In this study, we aimed to investigate whether ferroptosis was involved in alcohol-induced depressive and anxiety-like behaviors in mice.

PM exposure-induced ferroptosis in neuronal cells via inhibiting ERK/CREB pathway.

PM exposure has been demonstrated to correlate with neurological disorders recently. Ferroptosis is recognized as a newly found programmed form of cell death associated with neurodegenerative diseases, while glutathione peroxidase 4 (GPX4) is a key regulator of ferroptosis. However, the relationship between PM -induced neurotoxicity and ferroptosis is still unclear.

Candidate Chinese Herbal Medicine Alleviates Methamphetamine Addiction Regulating Dopaminergic and Serotonergic Pathways.

Methamphetamine (METH) addiction and its induced mental disorders have become a severe worldwide problem. A candidate Chinese herbal medicine (CCHM) in our lab had therapeutic effects on METH-induced locomotor sensitization, however, its chemical and pharmacological profiles remain to be elucidated. The current study aimed to investigate the effect of CCHM on conditioned place preference (CPP) induced by METH and screen the main active ingredients and key targets by using network pharmacology and molecular docking methods.

Terminalia chebula extracts ameliorate methamphetamine-induced memory deficits via activating the ERK and Nrf2 pathway.

As a psychoactive substance abused worldwide, methamphetamine (METH) abuse leads to multiple neurodegenerative symptoms including memory deficits. Terminalia chebula retzius extracts (TREs) isolated by our lab have great antioxidant activity and its effect on METH-induced memory deficits has not been investigated yet. The present study was designed to investigate the protective effect of TREs on METH induced cell apoptosis in vitro and memory deficits in vivo.

The exosome-circ_0001359 derived from cigarette smoke exposed-prostate stromal cells promotes epithelial cells collagen deposition and primary ciliogenesis.

Cigarettes consumption is continued to be popular. We found that cigarette smoke (CS) exposure promoted prostatic fibrosis. In this study, human prostate epithelial RWPE-1 cells were co-cultured with exosomes derived from CS exposed-WPMY-1 cells (CS-WPMY-1-exo).

Krill Oil Alleviated Methamphetamine-Induced Memory Impairment the MAPK Signaling Pathway and Dopaminergic Synapse Pathway.

Methamphetamine (METH) abuse exerts severe harmful effects in multiple organs, especially the brain, and can induce cognitive dysfunction and memory deficits in humans. Krill oil is rich in polyunsaturated fatty acids, while its effect on METH-induced cognitive impairment and mental disorders, and the underlying mechanism remain unknown. The aim of the present study was to investigate the protective effect of krill oil on METH-induced memory deficits and to explore the molecular mechanisms by using an integrated strategy of bioinformatics analysis and experimental verification.

The exosome-like vesicles derived from androgen exposed-prostate stromal cells promote epithelial cells proliferation and epithelial-mesenchymal transition.

Benign prostatic hyperplasia (BPH) is an age-related disease in men. Mesenchymal /stromal and epithelial cells interactions are essential to prostate functions. In this study, human nonmalignant prostate epithelial RWPE-1 cells were cocultured with testosterone (TE) -exposed prostate stromal fibroblasts WPMY-1 cells (TE-WPMY-1).

Lipopolysaccharide accelerates fine particulate matter-induced cell apoptosis in human lung bronchial epithelial cells.

Objectives: The aim of the study has been to investigate the effect of the Standard Reference Material of fine particulate matter (SRM 2786) on cytotoxicity and apoptosis in human lung bronchial epithelial cells (16HBE cells). Whether the lipopolysaccharide (LPS)-induced inflammation could further accelerate cell apoptosis induced by SRM 2786 stimulation has also been determined.

Material And Methods: 16HBE cells were exposed to various doses of SRM 2786 with or without LPS.

Combined effects of fine particulate matter and lipopolysaccharide on apoptotic responses in NR8383 macrophages.

Alveolar macrophages (AM) are the predominant lung cells responsible for both ingestion and clearance of inhaled particulate matter (PM). The aims of this study were (1) to examine effects of fine PM on rat NR8383 cell line apoptosis, and (2) to determine whether NR8383 cell functions are further affected when exposed to fine PM in the presence of inflammation induced by lipopolysaccharide (LPS). Standard Reference Material 2786 (SRM 2786) for fine PM was used to measure the following parameters: cytotoxicity, apoptotic rate, Bax/Bcl-2 expression, nitric oxide (NO) production, and reactive oxygen species (ROS) generation in NR8383 cells.
