Urinary MicroRNA-21 for Prostate Cancer Detection Using a Silver Nanoparticle Sensor: A Promising Diagnostic Tool.

In this study, we detected the expression levels of miR-21 in 38 clinical urine samples, obtained from 10 patients with PCa (with each sample obtained at three time points: before surgery, 1 month after surgery, and 3 months after surgery), 3 patients with benign prostatic hypertrophy (BPH), and 5 healthy subjects (as a control group). All of the samples were examined using a silver nanoparticle-based biosensor, and the sensitivity of the biosensor was simultaneously confirmed via qRT-PCR. The results were further analyzed together with clinical data such as PSA values and cancer stages.

Molecular Biological Mechanisms of Action of Chrysophanol in Hepatic Stellate Cells Activated by Hepatic B Virus X Based on Network Pharmacology.

Introduction: Chrysophanol (Cho) is a natural anthraquinone with biological effects such as inducing ferroptosis and anticancer activity. The hepatitis B virus X protein (HBx) is essential for HBV replication. We aimed to identify the key pathways in HBx-induced hepatic stellate cell (HSC) activation and to characterize the potential mechanisms of action of Cho against liver fibrosis.

Utilizing two-dose difference combined with stable isotope tracing for effective and comprehensive metabolite identification of pioglitazone via ultra-high-performance liquid chromatography-mass spectrometry.

Drug metabolite identification is an essential characterization process spanning multiple phases of drug discovery and development. Various data processing techniques have been employed in metabolite identification using high-resolution mass spectrometry. However, metabolite identification is not consistent among approaches.

Advanced metabolomics-based approach to reveal new insights into Bisphenol A metabolism and its presence in human excreta and water bodies in Taiwan.

Bisphenol A (BPA) is an environmental contaminant and can be detected in foodstuffs. Hence, investigating BPA metabolism in humans is crucial because certain BPA metabolites may exhibit similar or even greater be toxicity than does the parent compound. In this study, we used an advanced metabolomics-based data processing approach along with ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) to identify BPA metabolites in human liver enzyme incubation samples, and those metabolites were further detected in human excreta and water body samples in Taiwan.

An integrated platform for investigating drug-microbial interactions to support pharmacomicrobiomics studies.

Investigation of drug-microbial interactions has gained prominence due to the increasing need to study pharmacomicrobiomics. Previous research has revealed the microbiome's role in drug metabolism, influencing efficacy, bioavailability, and toxicity. Several potential interactions have reported between drugs and microbes, including bioaccumulation, biotransformation, and the influence of drugs on microbial growth.
