Environmentally persistent free radicals (EPFRs) are a recently recognized component of particulate matter that cause respiratory and cardiovascular toxicity. The mechanism of EPFR toxicity appears to be related to their ability to generate reactive oxygen species (ROS), causing oxidative damage. EPFRs were shown to affect cytochrome P450 (P450) function, inducing the expression of some forms through the Ah receptor.

Purpose: After failing primary and secondary hormonal therapy, castration-resistant and neuroendocrine prostate cancer metastatic to the bone is invariably lethal, although treatment with docetaxel and carboplatin can modestly improve survival. Therefore, agents targeting biologically relevant pathways in PCa and potentially synergizing with docetaxel and carboplatin in inhibiting bone metastasis growth are urgently needed.
Experimental Design: Phosphorylated (activated) AXL expression in human prostate cancer bone metastases was assessed by immunohistochemical staining.

In this study, we synthesized 12 monofunctional tridentate ONS-donor salicylaldimine ligand ()-based Ru(II) complexes with general formula [(Ru()(-cymene)]·Cl (-), characterized by H NMR, C NMR, UV, FT-IR spectroscopy, HR-ESI mass spectrometry, and single-crystal X-ray analysis showing ligand's orientation around the Ru(II) center. All 12 of these 12 complexes were tested for their anticancer activities in multiple cancer cells. The superior antitumor efficacy of , , and was demonstrated by reduced mitochondrial membrane potential, impaired proliferative capacity, and disrupted redox homeostasis, along with enhanced apoptosis through caspase-3 activation and downregulation of Bcl-2 expression.

Unlabelled: Bioluminescence imaging (BLI) using engineered bioluminescent viruses has emerged as a powerful tool for real-time, noninvasive monitoring of viral replication in living animals. While traditional luciferase-based systems, such as firefly luciferase, have been widely used, the NanoLuc luciferase system offers distinct advantages, including its significantly smaller gene size, increased brightness, and independence from ATP as a cofactor, allowing for extracellular detection. However, the utility of NanoLuc has been limited by its traditional substrate, furimazine, which exhibits poor water solubility and potential cytotoxicity.

Introduction: Intestinal lymphoma may be latent in some dogs with chronic inflammatory enteropathy. Mesenchymal stromal cells (MSCs) have potential therapeutic applications for refractory chronic inflammatory enteropathy, but their impact on the development of potential intestinal lymphomas has not yet been evaluated. Therefore, this study was performed to investigate the effect of canine adipose-derived MSCs (cADSCs) on the growth of canine lymphoma cell lines to assess the safety of MSC-based therapy in terms of pro- and anti-tumorigenic effects.
