Fenbendazole Exhibits Differential Anticancer Effects In Vitro and In Vivo in Models of Mouse Lymphoma.

ABSTRACT: Fenbendazole (FBZ) has been safely used as an antiparasitic agent in animals for decades, and the anticancer effects of FBZ have been studied through various mechanisms. However, there is a lack of in vivo studies that include lymphoma. Therefore, this study examined the effects of FBZ on EL-4 cells and a mouse T lymphoma model. FBZ induced G2/M phase arrest in EL-4 cells, resulting in cell death and decreased metabolic activity. However, FBZ had no anticancer effects on an EL-4 mouse lymphoma model in vivo, as evident by rapid weight loss and tumor growth comparable to the control. The FBZ-treated EL-4 cells expressed higher levels of PD-L1 and CD86, which are associated with T cell immunity in the tumor microenvironment (TME), than the controls. Furthermore, the hematoxylin and eosin staining of the FBZ-treated tumor tissues showed a starry sky pattern, which is seen in actively proliferating cancer tissues, and an immunohistochemical analysis revealed a high percentage of immunosuppressive M2 macrophages. These changes in the immune activity in the TME contradict the results of the in vitro experiments, and further studies are needed to determine the detailed mechanisms by which FBZ induces these responses.

Project description:BackgroundToxoplasma gondii is an obligate protozoan parasite capable of infecting a wide range of warm-blooded animals and humans. Current treatment options, primarily pyrimethamine and sulfadiazine, have limitations, such as high recurrence rates, long treatment durations, and limited effectiveness against T. gondii. There is an unmet need for novel, safe, low-toxicity, and highly effective treatments. This study aimed to evaluate the anti-T. gondii effects of glabridin, a natural compound derived from the roots of a widely used medicinal plant.MethodsThe cytotoxicity of glabridin in Vero cells was assessed using a CCK-8 cell viability assay. Quantitative polymerase chain reaction (qPCR) targeting the Tg-529 gene was developed to quantify T. gondii and assess the inhibitory effects of glabridin on parasite proliferation. Ultrastructural changes in T. gondii after treatment were examined using electron microscopy. The levels of reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) were examined to assess the effects of glabridin on ROS levels and ΔΨm in T. gondii tachyzoites. Additionally, metabolomics and transcriptomics analyses were conducted to investigate the mechanisms underlying glabridin's anti-T. gondii effects.ResultsGlabridin exhibited low toxicity to host cells and effectively inhibited T. gondii invasion and proliferation in vitro in a time-dependent manner. Glabridin-treated tachyzoites exhibited significant structural alterations, along with increased ROS production and a reduction in ΔΨm. Metabolomic analysis indicated that glabridin significantly affected amino acid metabolism pathways in T. gondii. In vivo, glabridin treatment significantly improved survival rates in T. gondii-infected BALB/c mice at a dosage of 100 mg/kg.ConclusionsThis study demonstrates that glabridin has potent anti-T. gondii effects in vitro and in vivo, likely through disruption of amino acid metabolism in the parasite. These findings highlight glabridin's potential as a promising therapeutic agent for toxoplasmosis.
